Form input autofocus attribute
Is there a way to disable the 'autofocus' attribute from the text form inputs without manually hacking it out of the source code? I have issues on long forms where the autofocus shifts the page to the bottom of the form as soon as it is loaded because of that attribute (on pages using the #forminput parser functions). Removing it after the fact with jQuery doesn't work because by the time the jQuery call kicks in, the page has already been shifted down from the autofocus. --Lalquier (talk) 14:35, 4 April 2017 (UTC)


 * Nevermind - Answering my own question. I reviewed the list of parameters for #forminput and found I missed the 'noautofocus' parameter. --Lalquier (talk) 14:42, 4 April 2017 (UTC)

Pipes are not working with wikitable format
I get the following error when using a simple wikitable in a textarea box. Actual error message is "|" is not allowed, except within or ...

I see this was reported previously here: https://www.mediawiki.org/wiki/Extension_talk:Page_Forms/Archive_January_to_March_2016#Pipes_are_not_allowed

But it seems to be not working for us now. Version used: PageForms 4.0.2 (f0816ba) 22:12, 6 January 2017

 * A naked pipe will be interpreted as the end of the parameter you are trying to set with your field. Did you try transcluding the pipes with | ? - Lbillett (talk) 09:30, 7 April 2017 (UTC)


 * I am trying to use the WikiEditor to insert a table. The basic format of the table has pipes. I don't think I can transclude them, maybe tables just don't work with page forms?--Nischayn22 (talk) 13:27, 5 June 2017 (UTC)

Nested Forms with Multiple Instances
I'd like to have a form that allows multiple instances and has an optional sub-form that can go with each instance. For example, you may have a main form (form "Item"), which can have an "Item Detail" sub-form. And you can have multiple "Item" instances, each with its own sub-form. Is this possible? I think this is what the partial forms are for, but I cannot figure out how to use it. Thanks in advance. Gstupp (talk) 20:12, 9 April 2017 (UTC)


 * Are you asking about having a form that only edits one instance of a multiple-instance template? If so, unfortunately that's not possible. Yaron Koren (talk) 22:41, 9 April 2017 (UTC)

Autocomplete not working
Can you think why autocomplete isn't working with the following?

I am sure it used to work, but I can't think what's changed. Thanks. Jonathan3 (talk) 14:15, 28 April 2017 (UTC)


 * Someone else said this was a problem too, but I can't reproduce it. Do you see any JavaScript error message in the browser console? Yaron Koren (talk) 17:35, 28 April 2017 (UTC)


 * Yes. This is from Firefox:

 * Could you add "?debug=true" (or "&debug=true") to the URL, to see if a more helpful error message can be seen? Yaron Koren (talk) 14:37, 30 April 2017 (UTC)


 * That didn't make any difference. It may be because I'm still using PF 4.1 (7f1cec5). I can't easily upgrade, as I haven't written that map/coordinates code for you yet, so have to add it each time... I'll get back to you when I do get the latest version. Jonathan3 (talk) 22:27, 1 May 2017 (UTC)


 * Ah - I'm pretty sure that upgrading will fix the problem, but until then, implementing these two changes directly in your code should hopefully fix the problem as well. Yaron Koren (talk) 01:58, 2 May 2017 (UTC)


 * I have reproduced the problem here, can you see it ? Nicolas NALLET Wiki-Valley.com, Semantiki.fr (talk) 09:40, 2 May 2017 (UTC)


 * This might be a different issue - in the JS console for that page, there's a Chameleon skin error that might be blocking the rest of the JS. Yaron Koren (talk) 13:36, 2 May 2017 (UTC)


 * Ok it's working now with Page forms version 4.1 (bb3327e) avril 27 2017 both here and vector skin based wikis. Thanks Yaron Nicolas NALLET Wiki-Valley.com, Semantiki.fr (talk) 07:04, 7 May 2017 (UTC)

Different list behaviour between dropdown and combobox
I have a property that has a set of allowed values defined using Allows value::xyz. If I put a field on a form related to this property, and I set the input type to dropdown, the dropdown list displays all the allowed values. In older Semantic Forms versions, the combobox input type also displayed the same list. Now, though, the combobox input type only lists the values that are actually assigned to the property on other pages. Is there any way to get the combo box to list all the allowed values?

Empty hidden field
Hello,

I'm trying to use an empty hidden field like this:

I want the form to automatically add  to the template on the new page. But it does not seem to work, this parameter is not added to the new page.

Is there any way to do that?

Issue with two datetimepickers in the same form
Hi, I have an issue when two datetimepickers are used in the same form. The datepicker-part is missing, but the time-part is shown. The problem disappears when I reduce to only one datetimepicker in the form.

Is there a limit on number of values in a dropdown when populated from cargo fields?
I am trying to populate a dropdown (or combobox) using tokenized data stored as a single "List of String" in a Cargo table.

The dropdown works - in that it populates, and I can select individual list items - but it looks like it's stopping at around 100 entries. Is this a limitation of values dependent on using Cargo, or is this a limitation with using a tokenized single list?

Here is the field declaration in the muti-instance template:

The data is stored as in a separate template.

Before I look to structuring the data differently (ie, store ThirdPartyCollect as separate rows instead of a delimited single entry), I'd like to know if this would solve the issue. FYI, the real goal is actually to combine several Cargo fields into a single, alphabetized dropdown in the spreadsheet-style view. I've almost got this in place, but it's konking out at 100 entries in the dropdown.

--Bgrenon (talk) 02:17, 16 May 2017 (UTC)


 * Is this happening in the spreadsheet display, or in a standard display? Or both? Yaron Koren (talk) 15:17, 16 May 2017 (UTC)

It looks like both. --Bgrenon (talk) 15:48, 16 May 2017 (UTC)


 * The fact that it's happening in the spreadsheet is not that surprising, but with the standard display it's quite surprising. What versions are you using of Page Forms and Cargo? Yaron Koren (talk) 17:49, 16 May 2017 (UTC)

Cargo 1.1.1 and Semantic Forms 3.7 --Bgrenon (talk) 18:19, 16 May 2017 (UTC)


 * Oh... those are both old, as I'm guessing you know. Maybe upgrading to the latest versions would fix the problem? Yaron Koren (talk) 18:31, 16 May 2017 (UTC)

Same settings, different resulting fields
I am not sure if it is a PF issue, but here we are: I have these two form fields:

the only difference between the two is the name field. But when the form loads, it looks like different. See. We can see from the URL that both of the fields are sending the same information: Institution[Has hierarchical superior]=Configuração:Institution 003 & Institution[Has parent page]=Configuração:Institution 003

Autocompetion on Category
Hi, I am using PageForms to create pages with sequential names, e.g. 'PageName 0001', 'PageName 0002' etc. To avoid duplications I used the argument 'Autocomplete on category', so users can check if a page name already exists. This is very useful until there are few pages, but when they become hundreds, users are obliged to guess which will be the next 'free' page name. I didn't find anything in Page Forms user guide to solve this problem. While I was searching for a solution I have a simple idea about how to solve it: it would be enough to set 'Autocomplete on category' to show page names in a reverse alphabetical order (Z to A), so users would immediately see the last page name used. Does anyone know if this could be a possible solution?

Update: I have found something here.

Thanks,

Value delimiter
Hi, there is an issue that I am not able to fix by myself.

I have a very simple form to create bibliographical pages; in the template I set the field 'Name' as follows:

The same field in the form is set as follows:

When I start typing the field, autocompletion appears as expected; but if I select one of suggested values, a comma is automatically added after the value. If I add a new value, the same happens; after saving, the whole field contains a unique value composed by all the values that I have added, separated by a comma. Now, I understand why this happens, since in the template the delimiter is semicolon. If I come back to the field and I manually change comma with semicolon, the values are actually processed as two different values, but, after saving, I see them separated by comma not semicolon. This is one issue.

Secondly, when I am filling the form and I use semicolon to separate the values, autocompletion doesn't work; otherwise, it works if a I use a semicolon.

Am I missing something very basic? Please help!

Thanks,

--Loman87 (talk) 12:11, 6 June 2017 (UTC)


 * I didn't really understand the second issue, but I'm guessing that both would be fixed if you added "|delimiter=;" to the field tag in the form definition. Normally the form would be able to figure that out from the template, but somehow it's failing here - maybe because of the parentheses in the field name. It seems like a Page Forms bug, in any case. Yaron Koren (talk) 13:37, 6 June 2017 (UTC)
 * I meant 'otherwise, it works if a I use a comma', sorry. However I added "|delimiter=;" to the field tag in the form definition and everything works fine, both visualization and autocompletion. Thanks for the help. --Loman87 (talk) 14:06, 6 June 2017 (UTC)

Dollar symbol issue
I have a form with a price input, but for some reason whenever I enter say "$100" it becomes "0" or "$9.55" becomes ".55". am I doing something wrong? or is something else affecting this? -- Cy be r XR ef ☎ 06:39, 8 June 2017 (UTC)


 * That was a problem a while ago, but I thought it was fixed already. What version of Page Forms are you using? Yaron Koren (talk) 14:10, 8 June 2017 (UTC)


 * Page Forms 4.1.1, Semantic MediaWiki	2.5.0 -- Cy be r XR ef ☎ 16:52, 8 June 2017 (UTC)


 * Well, there's a slightly newer version of PF, but I doubt that's the issue. What version of MediaWiki are you running? What is the input type of that field? And what is the type of the corresponding SMW property? Yaron Koren (talk) 18:34, 8 June 2017 (UTC)


 * We're using MediaWiki 1.28.1 and the input is just "text". The problem occurs in any field I enter a number starting with a dollar symbol actually.
 * If I enter "$123.456" in pretty much any field. When I click the "Show changes" the value shows up as:.
 * This is true even if I disable JavaScript, Just to make sure I don't have some conflicting library. -- Cy be r XR ef ☎ 20:36, 8 June 2017 (UTC)


 * I just tested it some more and discovered this only happens when I work on pages with existing template. If I try to create a new page with the form, it saves the value correctly (e.g., "$123.456"). Maybe this can help pinpoint the exact issue. -- Cy be r XR ef ☎ 22:21, 8 June 2017 (UTC)


 * I can't reproduce this issue, with either new pages or existing pages. Is this a public wiki, by any chance? Also, I would try upgrading to the latest version of PF - who knows, maybe that will fix it. Yaron Koren (talk) 15:42, 9 June 2017 (UTC)

Two forms in one Page
Is there a way to edit two forms in the same time on the same page ? --Paul LEMPERIERE (talk) 19:29, 9 June 2017 (UTC)


 * Sorry, I don't know what you mean exactly. Yaron Koren (talk) 15:43, 9 June 2017 (UTC)


 * For exemple, I want to create a page "Project 0001" and a page "Event 0001", using a form called "Project" and a form called "Event". But I don't want to call successively this two forms. I want to create the two pages in the same time. Is it possible ? --Paul LEMPERIERE (talk) 19:29, 9 June 2017 (UTC)


 * Alternatively, I'd say you want to use a single form - not two - to create as well as edit two separate pages, right? What you could do is use the AutoCreatePage extension to create your second page (Event 0001) automatically as soon as the first page (Project 0001) is created. Secondly, ensure that the first page contains the source data for both pages but only show the information relevant for each page. This requires that your second page contains calls to your master page - clever transclusion or use of queries through the Semantic MediaWiki extension or Cargo could help you with that. Cavila 06:45, 11 June 2017 (UTC)


 * Thanks a lot, it seems that this is the good way to solve my problem ! But I have another question : in a standard form, you can use the "page name=" parameter combined with the tag to generate incremental and unique page name. That's what I use to define the name of my "Project" pages (Project 0001, Project 0002,Project 0003,...). Unfortunately, when I use the parser provided by the AutoCreatePage extension to create my event pages, I can't use this way to name the pages, and so I can't name incrementally my events (Event 0001, Event 0002,...). Do you know a way to solve this problem ? Thanks ! --Paul LEMPERIERE (talk) 09:25, 5 July 2017 (UTC)

Image in a combobox

 * I think you can do this only in a roundabout way, via the External Data extension - see here. It's somewhat confusing, especially if the image data comes from MediaWiki itself - let me know if any of it doesn't make sense. Yaron Koren (talk) 03:05, 12 June 2017 (UTC)

formlink variable doesn't get parsed through (SOLVED)
Hi, I following direction from: https://www.mediawiki.org/wiki/Extension:Page_Forms/Linking_to_forms#Using_.23formlink to parse through a value to a variable using formlink. In the example the 'pagename' gets assigned to 'Author' in the cargo table Quote. I'm trying something similar for example: http://csdms.colorado.edu/wiki/Model:HydroTrend#References. The 2 buttons ( "Automatically enter Reference by DOI" and "Manually enter Reference" ) are defined at: http://csdms.colorado.edu/wiki/Template:AddReferenceUploadButtons. The formlink contains the table name, variable and value (pagename) as indicated, but the value doesn't get passed. Is this because the template in the form is set up to hold multiple values ? This is how the URL looks when trying to parse through the variable: http://csdms.colorado.edu/wiki/Special:FormEdit/Reference-auto1?RefsInt2%5BPublicationMultipleModelsCargo%5D=HydroTrend so seems like almost working to me. Tested this in Chrome.

Thanks, --Albert Ke (talk) 16:16, 14 June 2017 (UTC)


 * Yes, the query string for multiple-instance templates needs to be different - if you replace "RefsInt2[PublicationMultipleModelsCargo]" with "RefsInt2[1][PublicationMultipleModelsCargo]", it should work. By the way, if you only have one field in the template, it doesn't seem worth it to have that template... you can just replace it with a field that holds a list of values, like a "tokens" input. Yaron Koren (talk) 17:45, 15 June 2017 (UTC)
 * Works!! That was a simple fix, thank you! I'll look into the "tokens" input, thanks, --17:53, 15 June 2017 (UTC)

Is it possible to hide empty sections?
Hi, is it possible to not add to the page the heading for sections left empty? I see the extension does this for empty template parameters, and I'm looking to have the same happen with empty sections. Is it possible? If not, could you point me in the right direction to accomplish this in code? Thanks, FFS Talk 12:48, 21 June 2017 (UTC)


 * It's not possible, but it sounds like an interesting idea. You would have to modify lines 171-178 of includes/wikipage/PF_WikiPage.php - and possibly more if you wanted to make it a true form option. Yaron Koren (talk) 18:55, 21 June 2017 (UTC)


 * Thanks for pointing the way! Since I definitely do not want to keep a fork of my own, I ended up doing it as an option (editing PFPageSection, PFWikiPageSection, PFFormPrinter and PFWikiPage). It was really easy to dive into your code! I'll try to clean it up and submit as a patch soon, so you can behold in horror the result of my horrendous naming skills. And maybe even merge it, eventually :-) FFS Talk 23:54, 21 June 2017 (UTC)


 * Actually, I have a question - I currently have it implemented as a section-by-section option ("hidewhenempty"). I'm not sure if that makes any sense; do you think it makes more sense to have it as a global configuration option, or maybe a form-level one? For my use case it doesn't matter at all (I will always hide empty sections on my wiki). FFS Talk 11:02, 22 June 2017 (UTC)


 * That's an interesting question. I agree that this would be a useful feature, but I think you're the first person who has asked about it, which means that I don't know what all the potential use cases for it would be. But it seems to me that a section-based option, like you have it, is the safest approach. Though maybe calling it "hide when empty" (with spaces) is better... Yaron Koren (talk) 15:00, 22 June 2017 (UTC)


 * OK, so I submitted 361238 and added you as a reviewer. I'd love your feedback and to know what mistakes I made along the way :-) FFS Talk 20:25, 24 June 2017 (UTC)

datepicker not usable
Hi Yaron,

i'm using PageForms 4.1.2. Fields with a a datepicker-type and a datetimepicker-type appear like usual fields. Here's the code from the form: There's no error on js-console. This is the html-code generated by the system: Wunschdatum:  What's wrong? --217.234.159.235 09:11, 26 June 2017 (UTC)

"Show on select" not working properly
I maintain the website where, among others, one can find information about locomotives. A locomotive can have status "scrapped", "in running order", "exhibit" and so on. Depending on the status the form displays some fields, and some fields not. In some cases the fields are the same - only instructions shown to the editor differ. When an editor uses the form to create a new record everything is fine. But when he wants to update information a problem appears. The form shows values in fields only when the fragment of the code responsible for displaying them is in the first block of conditional code. Example:

. ..

. ..

. ..

So when the status of the locomotive is "Złom" (which means scrapped) or "Ostawiona" (out of order) and the user wants to edit an existing page fields in the form are empty (values are not shown though they exist in the code of the page). When the status of a locomotive is "Sprawna" (in running order) values in the fields of the form are shown properly. Shortly said: data are shown in fields of the form only if the div responsible for displaying them is first in the code. When it is second, third and so on - fields of the form are empty. Is it a bug or it is me doing something wrong?

I use MediaWiki 28.2, SMW 2.5.2 and PageForms 4.1.1. But the problem also existed when I used slghtly older versions of MW, SMW and PF. Regards Pawel Niemczuk (talk) 17:02, 1 July 2017 (UTC)


 * Could you link to (if it's on a public wiki) or pastebin the entire form definition? Yaron Koren (talk) 02:35, 3 July 2017 (UTC)
 * Yaron, thank you for your prompt reply. In the meantime I've analyzed the code and rethought it. And I've come to the conclusion that it is my mistake and wrong way of thinking. So apparantly the code, though it is not displayed, is still parsed. And this produces unforseen or unwanted behaviour. Shortly said: if there are several divs which are displayed (or not) depending on selected value they should not use the same names of fields. So in order to avoid unwanted behaviour one should either carefully design the code of the form or, what is way more complicated, cumbersome, not elegant and obfuscates the code, redesign it changing names of the fields which are repeated in different divs (and, consequently, redesign templates, queries etc.).

To make a long story short: I think I've found the solution and once the form is ready I'll post links to both old and not working version and the new working one. Pawel Niemczuk (talk) 23:36, 3 July 2017 (UTC)

It worked for a moment by replacing it with a call to https://cdnjs.cloudflare.com/ajax/libs/openlayers/2.13.1/OpenLayers.js but after a day or so, this, too, failed.

Special:CreateClass over rides property pages with no warning
It appears that when I use Special:CreateClass and input properties that already exist, I edit the property pages with no warning. A user kept changing my properties page type from Has type::Page to Has type::Text and they didn't realize it because they were using Special:CreateClass. --Mav-Tek (talk) 17:09, 5 July 2017 (UTC)

Default filename when using "uploadable" parameter
Is it possible to base the default filename on the current contents of one of the form's own fields? Thanks. Jonathan3 (talk) 00:41, 16 July 2017 (UTC)


 * No, unfortunately. Yaron Koren (talk) 22:52, 16 July 2017 (UTC)

Autocomplete in forminput only works once
I use this to create or edit a page with autocompletion on a category (PageForms 4.1.2):

Strangely, autocompletion in this input field only works one single time after I change something in the LocalSettings.php (regardless of what I change, can be just a new line). When I reload the page, it's not working anymore (until I change again the LocalSettings). Any idea, what's going on there? The autocompletion in the search bar works. Marccreal


 * When it's not working, do you see any errors in the JavaScript console? Yaron Koren (talk) 17:39, 19 July 2017 (UTC)


 * No, there are no errors (in Chrome the console under "More Tools/Developer tools" is the correct place to look, right?). The only thing, that shows up there are these warnings, but they always show up (and already when loading the page):
 * VM13225:70 This page is using the deprecated ResourceLoader module "jquery.ui.position"


 * VM13225:81 This page is using the deprecated ResourceLoader module "jquery.ui.widget".


 * This page is using the deprecated ResourceLoader module "jquery.ui.core". Please use "mediawiki.ui.button" or "oojs-ui" instead. Marccreal (talk) 22:15, 19 July 2017 (UTC)


 * More puzzling findings: The behaviour is "page-wise". Even when there are two different forminput with autocomplete to different categories, autocompletion works for both of them but only until I reload the page. But if I then go to another page with a forminput, it works there again (but again only until reload). Marccreal (talk) 22:37, 19 July 2017 (UTC)


 * Alright. I know about those JS warnings - I need to fix those, but they're unrelated to this issue. I'm pretty sure the problem is the MediaWiki cache - you don't need to edit LocalSettings.php to get the autocompletion temporarily working, you just need to add "?action=purge" to the URL, I think. I don't know why this is happening for you, though. Do you have some unusual MW caching setup? And what version of MediaWiki are you using? Yaron Koren (talk) 03:54, 20 July 2017 (UTC)


 * You are right, adding "?action=purge" makes the autocompletion work. I also suspected some problem with caching. The setting after installation was $wgMainCacheType = CACHE_NONE; I tried CACHE_DB, but this did not change anything (or do I have to do additional steps besides setting the variable?). During installation, the following warning was displayed: "Warning: Could not find APCu, XCache or WinCache. Object caching is not enabled." Marccreal (talk) 08:14, 20 July 2017 (UTC)


 * What version of MediaWiki are you using? Yaron Koren (talk) 11:50, 20 July 2017 (UTC)


 * Sorry, forgot to answer that: 1.29.0. I now changed to $wgMainCacheType = CACHE_ANYTHING; With that, autocompletion seems to work!


 * Oh - very interesting. It's great that you found a solution. I'll have to look into that; ideally this can work with any caching type. Yaron Koren (talk) 12:17, 20 July 2017 (UTC)
