   Hello all,

   I tried to realize a plugin that would allow me to replace some words by others in the post. I created the DB contained the words to replace and the word to put instead, i created the function and all is working fine, BUT, I don't find how to use it on BBPRESS.

   My function is something like
   echo replace_words($TextToBeTransform,$WordToReplace)
   , and the function use the DB to see what is be put instead of the $WordToReplace. As I can see, the post are printed out from the post.php of the template we do use.

   I got this:
   
<?php
$tset="A trial phrase.";
$WordToBeReplaced="trial";
?>
<div class="threadpost">
<div class="post">
<?php echo replace_words( $test,$WordToBeReplaced); post_text()?></div>
<div class="poststuff">
<?php printf( __('Posted %s ago'), bb_get_post_time() ); ?>
">#
<?php post_ip_link(); ?> <?php post_edit_link(); ?>
<?php post_delete_link(); ?></div>
</div>


   It print me exactly as I want the "A trial phrase" replace trial by "new" (from the DB).

   The problem is that when I want to apply this to the text of the post, post_text(), it won't work at all. I see that this post_text() is actually applying filters and others to the text, which my cause my function to fail (no error, it just don't replace the words).

   Could someone tell me where should I apply my own filter replace_words() for it to be taken into account?

   Thank you very much.

   I'm guessing get_post_text() would be your best option. post_text() doesn't return a value, it just pastes the text onto the page.

   You also need http://tw2.php.net/str_replace

   I think it's better to write a plugin (using a filter) for this task, instead of modifying template. (ya... this would be a good example to be "How to write a plugin" on my podcast show)

   I just finished uploading talkPress 002: A Simple bbPress Plugin - Bad Words Filter. You can watch this here.
   The code mentioned in video is:
   

   <?php
   /*
   Plugin Name: Bad Words Filter
   Plugin URI: http://www.livibetter.com/
   Description: Removing bad words from post content
   Author: Yu-Jie Lin
   Author URI: http://www.livibetter.com/
   Version: 0.1
   */
   
   function BadWordsFilter($post_text) {
   //  $post_text = str_ireplace('bad', '*****', $post_text);
   
       $bad_words = array('bad', 'topic', 'cialis');
       foreach($bad_words as $bad)
   //      $post_text = str_ireplace($bad, '*****', $post_text);
           $post_text = preg_replace("/\\b$bad\\b/i", '*****', $post_text);
   
       return $post_text;
       }
   
   add_filter('post_text', 'BadWordsFilter');
   ?>
