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');

?>
