validation not taking spaces in to account

[ldoozer]

I am using a standard form to mail script and have a few fields that I need to be required to be filled in.

This is working fine until someone enters a space character in a required field, which is being let thorugh.

 

How can I stop this? here the code for required fields -  I thought the trim function in the below would have taken care of this???

 

// This is because I originally had it require but too many people
// were used to Matt's Formmail.pl which used required instead.
if ($required)
   $require = $required;
// handle the required fields
if ($require) {
   // seperate at the commas
   $require = ereg_replace( " +", "", $require);
   $required = split(",",$require);
   for ($i=0;$i<count($required);$i++) {
      $string = trim($required[$i]);
      // check if they exsist
      if((!(${$string})) || (!(${$string}))) {
         // if the missing_fields_redirect option is on: redirect them
         if ($missing_fields_redirect) {
            header ("Location: $missing_fields_redirect");
            exit;
         }
         $require;
         $missing_field_list .= "<b><font color=\"#990000\">Missing: $required[$i]</font></b><br>\n";
      }
   }
   // send error to our mighty error function
   if ($missing_field_list)
      print_error($missing_field_list,"missing");
}

Trim the POST'ed values and then check for string length. An empty POST'ed value trimmed == ""

 

(or have strlen == 0)
