CakePHP "Agree TOS" Checkbox Validation

Question

I am trying to have a Checkbox "Agree TOS".

If the Checkbox is not checked, I want to put out a Flash Message.

How do I do this?

My View:

<?php   
        echo $form->create('Item', array('url' => array_merge(array('action' => 'find'), $this->params['pass'])));
        echo $form->input('Search', array('div' => false));
        echo $form->submit(__('Search', true), array('div' => false));
        echo $form->checkbox('tos', array('label' => false, 'value'=>1)).' Agree TOS'; 
        echo $form->error('tos');
        echo $form->end();
?>

My Model:

var $check = array(
            'tos' => array(
               'rule' => array('comparison', 'equal to', 1),
               'required' => true,
               'allowEmpty' => false,
               'on' => 'index',
               'message' => 'You have to agree TOS'
               ));

Your rules array should be $validate, not $check, I believe. — lxa

Maybe overkill, but you can also leverage a Confirmable Behavior. — mark

This seems working for me. Hope it will help.

In model:

            'tos' => array(
                'notEmpty' => array(
                    'rule'     => array('comparison', '!=', 0),
                    'required' => true,
                    'message'  => 'Please check this box if you want to proceed.'
                )

In view:

    <?php echo $this->Form->input('tos', array('type'=>'checkbox', 'label'=>__('I confirm I have read the <a href="/privacy-statement">privacy statement</a>.', true), 'hiddenField' => false, 'value' => '0')); ?>

basically, you add the rule "notEmpty" for this field to the public $validate array of the model. this way an error will get triggered on Model->validates() if the checkbox has not been checked.

maybe some overhead in your case, but if you happen to use it more often try a DRY (dont repeat yourself) approach. you can also use a behavior for this to use this clean and without tempering too much with the model/controller:

// view form
echo $this->Form->input('confirmation', array('type'=>'checkbox', 'label'=>__('Yes, I actually read it', true)));

and in the controller action

// if posted
$this->Model->Behaviors->attach(array('Tools.Confirmable'=>array('field'=>'confirmation', 'message'=>'My custom message')));
$this->Model->set($this->data);
if ($this->Model->validates()) {
    // OK
} else {
    // Error flash message here
}

I believe you need try save it into your model to catch your tos rules. I should do something like =

if(!$mymodel->save()){
 // catch error tos.
}

$this->ModelName->invalidFields() returns an array of fields that failed validation.

You could try and search this for the tos field, and output a message if the key exists.

~untested (I'm not sure off the top of my head the exact structure of the invalidFields return array.

$failed_fields = $this->ModelName->invalidFields();

if(array_key_exists('tos', $failed_fields)) {
    $this->Session->setFlash('Please accept the terms and conditions');
}

you don't even have to have validation rule for tos, just check that at the controller before saving the data.

if($this->data['Model']['tos']==1){
     // save data
  }else{
     //set flash
  }
