Show all model validation errors at the top of the page in cakePHP

Question

I am new to CakePHP. When I use Model Field Validations , then an error message appears infront of each field of the required form. I want to show it in a div at the top of the form. How can I implement this. Thanks in advance. Here is my code: Model:

 <?php class User extends AppModel { public $validate = array( 'username' => array( 'required' => array( 'rule' => array('notEmpty'), 'message' => 'A username is required' ), array( 'rule' => array('minLength', 8), 'message' => 'Username must be at least 6 characters long' ) ), 'password' => array( 'required' => array( 'rule' => array('notEmpty'), 'message' => 'A password is required' ) ), 'city' => array( 'required' => array( 'rule' => array('notEmpty'), 'message' => 'A City is required' ) ), 'state' => array( 'required' => array( 'rule' => array('notEmpty'), 'message' => 'A State is required' ) ), 'role' => array( 'valid' => array( 'rule' => array('inList', array('admin', 'author')), 'message' => 'Please enter a valid role', 'allowEmpty' => false ) ) ); } 

UsersController.php

 public function add() { $this->set('states_options', $this->State->find('list', array('fields' =>array('id','name') ))); $this->set('cities_options', array()); if ($this->request->is('post')) { $this->User->set($this->request->data); if($this->User->validates()) { $this->User->create(); if ($this->User->save($this->request->data)) { $this->Session->setFlash(__('The user has been saved')); $this->redirect(array('action' => 'index')); } else { $this->Session->setFlash(__('The user could not be saved. Please, try again.')); } } else { $errors = $this->User->validationErrors; $this->set('ValidateAjay',$errors); //pr($errors);die; } } } 

Custom view:

 <!--<script src="http://code.jquery.com/jquery-1.7.2.js"></script>--> <script> $(document).ready(function(){ $('#UserState').change(function(){ var stateid=$(this).val(); $.ajax({ type: "POST", url: "checkcity", data:'stateid='+stateid+'&part=checkcity', success: function(data) { $("#city_div").html(data); } }); }); }); </script> <div class="users form"> <?php if(!empty($ValidateAjay)){ pr($ValidateAjay); } echo $this->Form->create('User'); ?> <fieldset> <legend><?php echo __('Add User'); ?></legend> <?php echo $this->Form->input('username'); echo $this->Form->input('password'); echo $this->Form->input('state', array('options' => $states_options , 'empty' => 'Select State' )); ?> <div id="city_div"> <?php echo $this->Form->input('city', array('options' => $cities_options, 'empty' => 'Select City' )); ?> </div> <?php echo $this->Form->input('role', array( 'options' => array('admin' => 'Admin', 'author' => 'Author') )); ?> </fieldset> <?php echo $this->Form->end(__('Submit')); ?> </div> 

Answer 1

You can get all validation errors from the $this->validationErrors variable in the view. Then feel free to go through them and show how you like. They will be organized by model, for example:

 array( 'User' => array( 'username' => 'This field cannot be empty.', 'password' => 'This field cannot be empty.' ) ); 

You can then iterate over them on the screen and display them as such. In this example, they appear as an unordered list:

 $errors = ''; foreach ($this->validationErrors['User'] as $validationError) { $errors .= $this->Html->tag('li', $validationError); } echo $this->Html->tag('ul', $errors); 

Finally, you can hide automatic form error messages by hiding them using CSS or by setting default values ​​for FormHelper so that they do not appear.

CSS

 .input.error { display: none; } 

or

in view

 $this->Form->inputDefaults(array( 'error' => false ));

The jeremyharris example makes a lot of sense, however, if you don't want to manually set a loop for each form field, you can try the following:

 $errors = ''; foreach($this->validationErrors as $assoc) { foreach ($assoc as $k => $v) { $errors .= $this->Html->tag('li', $v); } } echo $this->Html->tag('ul', $errors); 

So, if your check returns several errors, the result will look like this:

  - A username is required - A password is required 

Answer 3

Although this is a very old post, I would like to answer my decision here as well.

To get model validation errors, just use $model->getErrors(); This will return an array of errors with the key field.

example

 $errors = $user->getErrors();
