Want to replace or remove offensive words in your WordPress comments? With our snippet, you can remove swear words or even affiliate links within your WordPress comments. However, keep in mind that the filtered content will be saved in WordPress.
Instructions:
All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:
add_filter( 'pre_comment_content', 'wps_filter_comment' );
function wps_filter_comment($comment) {
$replace = array(
// 'WORD TO REPLACE' => 'REPLACE WORD WITH THIS'
'foobar' => '*****',
'hate' => 'love',
'zoom' => '<a href="http://zoom.com">zoom</a>'
);
$comment = str_replace(array_keys($replace), $replace, $comment);
return $comment;
}

Instead of replacing words, is there a filter to add the words in the functions.php instead of in the wp-admin > discussion > Blacklist. Sure I can add it inside wp-admin but i’d like to just add it to the functions file.
This method would be for the functions.php file.
what happen if this keywords inside an img tag. I tried and it caused a problem. We can’t see images. My suggestion is it must be a filter that word must not inside a “img” and “a” tag. How can we check ?
good topic
function cudjex($text){$text = str_replace(‘sex’, ‘***’, $text);
$text = str_replace(‘porno’, ‘***’, $text);
$text = str_replace(‘cam?? ölüsü seni’, ‘***’, $text);
$text = str_replace(‘aq’, ‘***’, $text);
$text = str_replace(‘amk’, ‘***’, $text);
return $text;
}
add_filter(‘comment_text’, ‘cudjex’);the simple and useful 🙂
