   Hi,

   I used to use a plugin called smart link (by Semiologic.) It's now part of a commercial product, and the old version is no longer supported. And, the old version no longer works with WordPress 2.8.2, so all of my old links have died - i.e. are rendered in the page as [foo -> bah].

   I'm looking for one of two solutions:
   a) a plugin that lets me define a macro that will behave as a link with the syntax above
   b) the ability to find/replace using regex in all of my posts

   Ideas?

   Thanks

   You can replace text dynamically with a plugin. Here is a basic example:

   <?php
   /*
   Plugin Name: Replace text
   Plugin URI:
   Description:
   Author:
   Version: 1.0
   Author URI:
   */
   
   function replace_the_text($content) {
   	$content = str_replace("foo", "bah", $content);
   	return $content;
   }
   
   add_filter('the_content', 'replace_the_text');
   
   ?>

   As you can see, the 'replace_the_text' function gets the content of the post/page, modifies it, and returns it back where it is displayed.

   Thanks! Here's what I ended up with. The regex possibly needs a little tweaking, but it works on everything I've checked so far. I'm going to post this on the plugin repo in case anybody else needs it.

   <?php
   /*
   Plugin Name: Replace text
   Plugin URI: http://replacetext.com
   Description: Replaces text
   Author: Reuben Firmin
   Version: 1.0
   Author URI: http://www.flavor8.com
   */
   
   function replace_the_text($content) {
           $content = ereg_replace("\[([0-9a-zA-Z\(\)\'\" ]*)[ ]*\-\>[ ]*([0-9a-zA-Z:/\.\_\-\'\(\)]*)\]", '<a href="\2">\1</a>', $content);
           return $content;
   }
   
   add_filter('the_content', 'replace_the_text');
   
   ?>
