Warning preg_match() Delimiter nust not be alphanumeric or backslash - Cant fix

Question

I keep getting this error, the error is in reference to this section of code, can someone tell me what I am missing:

if(!preg_match("class",$parameters)) $parameters .=" class='ibox'";

$field = '<input type="' . tep_output_string($type) . '" name="' . tep_output_string($name) . '"';

Thanks!

You are missing delimiters.

!preg_match("/class/", $parameters)

It would be much more efficient to use strpos in this case.

strpos($parameters, "class") === false

Thanks for this, what would I use for this line: 'echo $domain . preg_replace( $search, $replace, $string);' as it is experiencing the same error. – user1764987 Feb 05 '14 at 19:05
`$search` variable probably doesn't have delimiters like `/` surrounding it either – Michal Brašna Feb 05 '14 at 19:06

You can use

if( strpos($param, "class") === false ) {
    // do 
 }
