Mediawiki understand the ... wikilinks as fully textual, so if you want to pass custom parameters to an article for later retrieving them using the Extension:UrlGetParameters extension, you should use an external link. This external link has its custom "external" css class, which provides a custom icon. If you can deal with this icon, you have no problem. But if you have external urls in your wiki text (and maybe you open them in an external window), you will not want an "external" behaviour for your internal links.

This extension enables the creation of wikilinks which allow get parameters as in the next example:

[[My/Article?param1=value1&param2=value2|Go to My/Article]]


Just use the classic GET format in your wikilinks

  • [[My/Article1?param1=value1]]
  • [[My/Article2?param1=value1&param2=value2]]
  • [[My/Article2?param1=value1&param2=value2|Go to]]
  • ...

File AllowGetParamsInWikilinks.php


 * Allow Get Params In WikiLinks
 * Funcion que hace que se permita el paso de parametros "get" en un enlce tipo WikiLink,
 * de la forma [[destino?param1=valor1&param2=valor2]]
 * Actualmente, un wikilink no permite esto y se traduce en una pagina entera con nombre
 * "destino?param1=valor1&param2=valor2". Esta extension arregla esto para que se le pasen
 * los parametros tipo "get" a la pagina "destino"
 * Posibles BUGS conocidos: cuando un articulo tiene ? en su texto y va a haber otro que tenga
 * un titulo exactamente igual, pero mas largo. Mientras no existe, se tomaria como un paso de
 * parametros. Una vez definido el articulo, ya se llegaria a el sin problemas porque se
 * reconoceria como un articulo existente; sin embargo, no se podría pasar parametros al artículo
 * corto.
