Update: Improved validation in CakePHP for version 1.x

I recently started a new project in CakePHP and thought it time to use version 1. But it seems the way that the validator code works has changed, so here is the updated code:

The following goes in app_model.php

Updated validator code
  1. function invalidFields ($data = array())
  2. {
  3. if (empty($data)) {
  4. $data = $this->data;
  5. }
  7. if (!$this->beforeValidate()) {
  8. return false;
  9. }
  11. if (!isset($this->validate)) {
  12. return true;
  13. }
  16. if (!empty($data)) {
  17. $data = $data;
  18. } elseif (isset($this->data)) {
  19. $data = $this->data;
  20. }
  22. if (isset($data[$this->name])) {
  23. $data = $data[$this->name];
  24. }
  26. $errors = array();
  27. foreach($this->validate as $field_name => $validators) {
  28. foreach($validators as $validator) {
  29. if (isset($data[$field_name]) && !preg_match($validator[‘expression’], $data[$field_name])) {
  30. $errors[$field_name] = $validator[‘message’];
  31. }
  32. }
  33. }
  34. $this->validationErrors = $errors;
  35. return $errors;
  36. }

The validation helper method (See my previous post) looks like this:

  1. function tagErrorMessages() {
  2. $messages = “”;
  3. if(isset($this->validationErrors)) {
  4. foreach($this->validationErrors as $tag) {
  6. foreach($tag as $element => $message) {
  7. $messages .= sprintf(SHORT_ERROR_MESSAGE, empty($message) ? ‘Error in field: ‘ . $element : $message);
  8. }
  10. }
  11. }
  12. return $messages;
  13. }
