   I would like to validate the zipcode field in my forms to check for a minimum of 5 characters. Currently people are adding state abbreviations in the zipcode and not getting an error message.

   how can I specify the validation for that field only?

   Thanks.

   Hi,

   Try to edit "includes/post-functions.php" file and go around line 479 ~ 481, you'll see these code :

   if($validation_result !== true){
   	$error_elements[$element_id] = $validation_result;
   }

   then put these code exactly bellow that line

   if ($form_id == 5) {
   	if (strlen(trim($target_input[$element_name_5])) < 5 && empty($error_elements[$element_id]) ) {
   		$error_elements[$element_id] = "Zip code must more than 5 Character";
   	}
   }

   Those code will work on form id 5, make sure you change the form id with yours

   Now people are entering the state name for example "Florida" and since there are more than 5 characters the form is accepting this entry.

   I added this to the code || !preg_match("/^[0-9][\w]*$/i",$value[5])

   Would this work?

   if ($form_id == 4 || $form_id == 10) {
   if (strlen(trim($target_input[$element_name_5])) < 5 && empty($error_elements[$element_id]) || !preg_match("/^[0-9][\w]*$/i",$value[5]) ) {
   $error_elements[$element_id] = "Zip code must be more than 5 Characters";
   }
   }

   If you need to allow numeric value only for "ZIP" code, try to use this code instead :

   if ((strlen(trim($target_input[$element_name_5])) < 5 || !is_numeric($target_input[$element_name_5])) && empty($error_elements[$element_id]) ) {
   	$error_elements[$element_id] = "Zip code must more than 5 Character";
   }

   I think it's more simple to use "is_numeric" function
