Extension:ExternalLinks

The ExternalLinks extension adds  which lists all external links used on the wiki including dynamic URLs by templates, i.e. all URLs stored in the externallinks table.

The special page lists the pages which use the URL (edit link with preview).

URLs can be filtered with a truncated text string.

URL validation
The extension also works as link checker by validating the reported URLs.

For each result page you can let PHP check the availability of each URL target by reporting its server response header (requires the  setting, see below).

You could also use a browser plugin like Pinger for Firefox.

Although e-mail addresses cannot be validated too easily, they can be added to the report list.

 * Define the validation mode, e.g..
 * If enabled, this setting will ignore your $wgMiserMode setting and can slow down your server.
 * Options:

Skip previously checked URLs
Optional: When you validate URLs you can store the date and skip these URLs next time, e.g. by hiding all URLs which have been validated (and stored) in the past X days.

will add the option Mark all URLs on result pages as "checked today".

To store the date you need to add a new row  to the  -table. Run this SQL command:

With stored dates you can later use the option Last validation is older than: [___] days

Coding
Please post if you have a working solution for


 * grouping results of different wiki pages with the same URL (same URLs should only be listed once with a list of the pages they're used on, should also work with )
 * a page name filter that excludes pages with a given string (like URL string filter)
 * a namespace selector as on Special:Search
 * validating https-URLs
 * validating flash-URLs
 * removing the toolbox link if the page doesn't use external URLs
 * This can be tricky since a simple javascript check for a link is not enough. An URL could be used in a templare to produce some content without a link of that URL (varying link, flash content, etc.).
