Hi,
I’m trying to make my first plugin, and I’m really not php dev, so I sweat a little bit...
Goal is to
manage automatically external links to add a wanted class (the string is contained into $extlink_class) + a
rel="external" statement to each of them. (in fine, the goal is to keep strict validity without ’
target_blank links’, some JS will do the final job).
I made something working, but it’s too basic and not idiot proof, because in the RTE, the redactor could have already added the external class manually to a link, AND a link could have already
some classes defined (my first version crusches the class statement).
What could be the preg_replace good expression to do the following :
The motif would be like this : in the dom look for each link, string beginning by ’<a’ followed by anything til the final ’>’
Look inside for a string beginning by ’class="’
Taking out inside this one the content (string) of $extlink_class (in cas it is already set)
them add it (again if it was here before, yes) to the previous class statement (keeping potential other already set classes)
I think about this as a beginning :
I’d like to use this :
$modx->documentOutput = preg_replace($the_motif,$the_replacement,$modx->documentOutput);
and here’s what I’ve done in the first basic version:
/*
Plugin: Auto-extlink , set OnWebpagePrerender
Description: Auto-extlink get all external links (http:// scheme) and add a rel="external" + class="ext-link" in your MODx content to all external links.
Version: 0.2
Author: Eric Lacomblez
*/
$extlink_class = 'lien-externe';
$text = $modx->documentOutput;
// search and replace external Links in document
$modx->documentOutput = str_replace('base href="http://','basehref="http://',$modx->documentOutput);
$modx->documentOutput = str_replace(' href="http://',' class="'.$extlink_class.'" rel="external" href="http://',$modx->documentOutput);
$modx->documentOutput = str_replace('basehref="http://','base href="http://',$modx->documentOutput);
return; // stop
thank you
