RE: [PHP] Form Validating Class (OOP misunderstandings...)

[@ Nilaab]

Nicholas,

I think I know where you found this code. I have the same code, except I
modified it a little to work for me. You may need to change it for your
needs. When I first used it, it didn't work. I had to modify it to make it
work. My code is usually kind of sloppy, but maybe you would get better use
of the following class:

<?php

class FormValidator {

var $_errorList;


function FormValidator() {
   $this->resetErrorList();
}


function isEmpty($field, $msg) {
   if (trim($field) == "") {
      $this->_errorList[] = array("value" => $field, "msg" => $msg);
      return true;
   } else {
      return false;
   }
}


function isZero($field, $msg) {
   if($field == 0) {
      $this->_errorList[] = array("value" => $field, "msg" => $msg);
      return true;
   } else {
      return false;
   }
}


function isUploadedFile($img, $img_type, $img_size, $msg) {
   $pattern = "/(pjpeg)$/";
   if (is_uploaded_file($img) && preg_match($pattern, $img_type) &&
$img_size <= 1000000) {
      return true;
   } else {
      $this->_errorList[] = array("value" => $img, "msg" => $msg);
      return false;
   }
}


function isString($field, $msg) {
   if(!is_string($field)) {
      $this->_errorList[] = array("value" => $field, "msg" => $msg);
