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',

    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 ?

  2. good topic

  3. 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 🙂
