Meta tags in skin from MediaWiki template

Hi! I'm a little bit confused with interacting between template and skin.

Let's say i have a template in my MediaWiki like

<includeonly>
 
 <div id="custom-person">
 
 * <span>Birthday:</span> {{#if: {{{birth date|}}} | <b>{{#ol-time:|{{{birth date}}}}}</b> | — }}
{{#if: {{{full name|}}} | * <span>full name:</span> <b>{{{full name}}}</b>}}
{{#if: {{{birth place|}}} | * <span>birth place:</span> <b>{{{birth place}}}</b>}}
{{#if: {{{age|}}} | * <span> age:</span> <b>{{{age}}}</b>}}
{{#if: {{{nationality|}}} | * <span> nationality:</span> <b>{{{nationality}}}</b>}}

<div class="clear"></div>

</div>

[[Category:Person]]

__NOTOC__

</includeonly>

All these pages are in one Namespace (0).

I need to generate head meta tags with data from this template.

I figured out how to filter such a pages and add title tags in my SkinPerson.php

if ( $out->getTitle()->getNamespace() == 0 ) {
    $out->addMeta( "description", $out->getPageTitle());
    $out->addHeadItem( 'og:description', '<meta property="og:description" content="' . $out->getPageTitle() . '">');
}

But I'm really stuck on how can I insert in, say, 'og:description' tag something like {{{full name}}} + {{{age}}} ?


Thanks in advance!

wikitext templates are not simple key values, they are multilevel nested templating with logic that generates HTML. As such it is hard to retrieve the result of a parameter and reuse it elsewhere. Traditionally, we use parser functions like for instance #coordinates provided by Extension:GeoData. This parser function then is executing during the parsing of all the wikitext code of a page, extracts values and puts them into a storage location where it is reachable with database functions.

Then you reuse that information every time the page is rendered.

Maybe you should use something like Extension:Page Forms to store and retrieve your values. I suspect it will have some hooks that will allow you to retrieve the data in a hook so that you can add head items etc.

Thank you! I'll try to solve it one of these ways

I use Extension:WikiSEO for this and suspect it would work for you too. I use it alongside Extension:Cargo but from memory it would work the same within any template.
