Replace keywords or cursing in the comments

Adding this snippet to the functions.php of your wordpress theme will replace keywords like cursing or even affiliate links within your post comments. May even be fun to change some random words lol, however keep in mind the filtered content will be saved.

add_filter( 'pre_comment_content', 'wps_filter_comment' );
function wps_filter_comment($comment) {
	$replace = array(
		'foobar' => '*****',
		'hate' => 'love',
		'zoom' => '<a href="http://zoom.com">zoom</a>'
	$comment = str_replace(array_keys($replace), $replace, $comment);
	return $comment;

    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 🙂
