I'm using cakephp 2.0 and I'm having problem using Cake's validation thing, which works wonderful when used for it alone.
var $validate = array(
'loginname' => array(
'minCharactersRule' => array(
'rule' => array('minLength', 3),
'required' => true,
'allowEmpty' => false,
'on' => 'create',
),
'alphaNumericRule' => array(
'rule' => 'alphaNumeric',
),
'uniqueRule' => array(
'rule' => 'isUnique',
),
),
'password' => array(
'minCharactersRule' => array(
'rule' => array('minLength', 5),
'required' => true,
'allowEmpty' => false,
),
// on so on ...
Due to Internalization I put the error messages into the view like this:
echo $this->Form->input('display_name', array(
// some other options ...
'error' => array(
'betweenRule' => __('Your Dispay Name must contain at least 3 characters and should be maximal 20 characters long.'),
'uniqueRule' => __('This Display Name is already in use!'),
),
);
Now I want jQuery to validate the form on client-side as well with some little - sexy message box to return validation errors if something goes wrong.
The Ajax Request works fine but the problem here is: I only get returned the name of the validation rule, not the message.
sure: Because I didn't specified any messages in the model.
But how can I get those messages I declared in the view?
Is there any solution without having to type everything twice (PHP and JS)?

I have a form on my homepage from an element in my Leads plugin. I have this in my Lead model:
public $validate = array(
'last_name' => array(
'notempty' => array(
'rule' => array('notempty'),
'message' => 'Your custom message here',
'allowEmpty' => false,
),
),
'phone' => array(
'rocket' => array(
'rule' => array('phone', null, 'us')
),
),
);
My app is validating correctly because it's not posting to my database unless I fill in required fields. The problem is that the because my url isn't /leads/add it's not showing my custom error messages on my fields when I submit the form.
I think it has something to do with the fact that I'm using an element. Anyone have any ideas or had trouble with this before?
The rule should be notEmpty instead of notempty. What is working right now is the allowEmpty set to false which makes sure the field is not empty using !empty($field) || is_numeric($field).
I just created a form in cakephp and I would like to do a validation for one of the field.
The form will only be submitted if this particular field is left empty.
Here's a my particular field
<?php echo
$this->Form->input('MyForm.fieldA', array(
'type' => 'text',
'label' => '',
'class' => 'span3 detector-form',
))
?>
And my validation code:
public $validate = array(
'fieldA' => array(
'rule' => 'blank',
'on' => 'submit',
'message' => 'Failed authorize',
'last' => true
),
);
P/s. I tried using
public $validate = array(
'fieldA' => array(
'rule' => 'blank',
'on' => 'create',
'message' => 'Failed authorize',
'last' => true
),
);
But the 'create' sounds like only worked when the field is created.So I changed to 'submit' for a testing purpose.
I tried to use rule''=> 'Empty' as well but the validation doesn't work. Or is there any other alternative rules that I can use to reach this goal?
I wrote a custom validation method inside my Submission model that basically allows a blank input field, but once someone enters something in it, it'll validate the data entered.
The validation inside my Submission Model looks like this (All other validation rules are working except for 'description'):
var $validate = array(
'title' => array(
'title' => array(
'rule' => 'notEmpty',
'required' => true,
'allowEmpty' => false,
'message' => 'Please enter a title'
),
'minLength' => array(
'rule' => array('minLength', 5),
'message' => 'Please make your title longer'
),
'maxLength' => array(
'rule' => array('maxLength', 300),
'message' => 'Your title needs to be shorter'
),
),
'description' => array(
'checkDescription' => array(
'rule' => array('validateDescription'),
'message' => 'Description must be greater than 5 characters'
),
),
'source' => array(
'source' => array(
'rule' => 'notEmpty',
'required' => true,
'allowEmpty' => false,
'message' => 'Enter a valid source URL'
),
'website' => array(
'rule' => 'url',
'message' => 'Please enter a valid source URL'
),
)
);
My method which is also in my Submission model (below the above code) is:
public function validateDescription($data) {
if(empty($data['Submission']['description']))
return true;
if((strlen($data['Submission']['description'])) <= 5)
return false;
}
I'm not sure why this isn't working at all. In my view, I've got this to display the error:
if ($form->isFieldError('Submission.description'))
echo ($form->error('Submission.description', null, array('class' => 'error')));
The only reason I'm trying to do this, is because using the normal validation with required => false and allowEmpty => true along with a minLength and maxLength validation rule weren't behaving how I intended.
Any help would be greatly appreciated! :)
The $data variable passed into the validation method only contains array($fieldname => $value). You're also not returning true for strings over length of 5. Your method should look like this:
public function validateDescription(array $data) {
$value = current($data);
return !$value || strlen($value) > 5;
}
I've some conditions to a form to be valid that has to be on several fields instead one, how to do this.
Some example for a registration:
enterprise or firstName+lastName filled
mobile phone number OR static phone number filled
How to do this? Is there an implemented way or I've to do it myself every time?
Thank you
Write your own validation rules. Cake Book: Custom validation rules
Attach a rule to the enterprise field what checks if it is filled or the first, last names are filled. Attach another rule to the name fields to check if the names or the enterprise fields are filled. Similar to the phone fields. You are in the model so you can reach all passed fields in $this->data
I am not sure if I understand the question correctly but you can create your own validation rule and then apply it for the desired fields (not really the other way around). See here
Otherwise Cakephp has a lot of pre-built validation rules here is an example:
var $validate = array(
'title' => array(
'titleRule1' => array (
'rule' => array('minLength', 1),
'required' => true,
'allowEmpty' => false,
'last' => true,
'message' => 'Please enter a title.'
),
'titleRule2' => array(
'rule' => array('between', 1, 100),
'message' => 'Your title must be between 1 and 100 characters long.'
)
),
'description' => array(
'rule' => array('minLength', 1),
'required' => true,
'allowEmpty' => false,
'last' => true,
'message' => 'Please write a description.'
)
);
I am trying to get multiple rules to run during an upload validation. One validation is built in and one is custom. The custom one works fine however the built in one is not working. The custom one extension was working on another field earlier just fine. Do I have this setup correct?
var $validate = array(
'description' => array(
'rule' => 'notEmpty',
'message' => 'This field cannot be left blank.',
'required' => true
),
'title' => array(
'rule' => 'notEmpty',
'message' => 'This field cannot be left blank.',
'required' => true
),
'Filedata' => array(
'rule' => array('FileExtCheck'),
'message' => 'Please supply a valid type.',
'required' => true
),
'Thumbdata' => array(
'dimensions'=>array(
'rule' => array('dimensions','120','142'),
'message' => 'Your image dimensions are incorrect: 120x142'
),
'extension' => array(
'rule' => array('extension'=>array('jpg','jpeg','png')),
'message' => 'Please supply a valid type.',
'required'=>true
)
)
);
The one I am having issue with is Thumbdata. I want the Thumbdata field to be required and make sure it has correct dimensions and is an image of jpg, jpeg or png. I don't want animated gif's.
I guess, you have a syntax error - unnecessary =>. Should be:
'rule' => array('extension', array('jpg','jpeg','png')),
