Cakephp, validate field if not required - php

Hi i encounter strange problem, i have this input in my form
$this->Form->input('processing_data', array('label' => 'STH', 'required' => 'required'));
and this produces this html
<input id="UserProcessingData" type="checkbox" value="1" required="required" name="data[User][processing_data]">
my model validating this field is User model and code of it :
'processing_data' => array(
'rule' => 'notEmpty',
'allowEmpty' => false,
'message' => 'Prosze zaznaczyć'
),
but let's say someone manually delete required="required" from input and then validation is not triggered i thought 'rule => 'notEmpty' will do but nothing changed so next i added 'allowEmpty' => false, but also it didn't help.
What can be done to validate this field even if required is not present

Use this-
'processing_data' => array(
'rule' => array('notEmpty'),
'required' => true,
'message' => 'Prosze zaznaczyć'
),

use required => true in model and you can true your allowEmpty validation if it is mandatory.
'processing_data' => array(
'rule' => 'notEmpty',
'required' => true,
'allowEmpty' => true,
'message' => 'Prosze zaznaczyć'
),

try this
'processing_data' => array(
'rule' => 'notEmpty',
'required' => true,
'allowEmpty' => false,
'message' => 'Prosze zaznaczyć'
),

ZF2 - Need to display specific error message on specific condition failure

I am using ZF2 form validation.I have to validate two fields USERNAME and PASSWORD.
everything is working fine but I am getting message like
Please enter username.
Username can not be less than 3 characters.
Please enter password.
Password can not be less than 6 characters.
If user is not entering any value then only this message should display
Please enter username.
Please enter password.
I don't want do display all the error messages on a field on failure.
Thanks in advance.
I got the answer :
In order to break the validation chain in ZF2 , we have to use
'break_chain_on_failure' => true
$this->add(
array(
'name' => 'usernmae',
'required' => true,
'filters' => array(
array('name' => 'Zend\Filter\StringTrim')
),
'validators' => array(
array('name' => 'NotEmpty',
'options' => array('encoding' => 'UTF-8',
'messages' => array(
NotEmpty::IS_EMPTY => 'Please enter username')),
'break_chain_on_failure' => true),
array(
'name' => 'Zend\Validator\StringLength',
'options' => array(
'encoding' => 'UTF-8',
'min' => 3,
'max' => 30,
'messages' => array(
StringLength::TOO_LONG => 'Username can not be more than 30 characters long',
StringLength::TOO_SHORT => 'Username can not be less than 3 characters.')
),
'break_chain_on_failure' => true
)
)
)
);
My Blog : http://programming-tips.in
Zend_Validate allow you to break validators chain if certain vaildation fails. The second parameter of addValidator() function $breakChainOnFailure should be TRUE in this case.
$validatorChain = new Zend_Validate();
$validatorChain->addValidator(new Zend_Validate_NotEmpty(), TRUE)
->addValidator(new Zend_Validate_StringLength(6, 12));
You can also set the 'error_message' key, for example:
'email' => [
'required' => true,
'error_message' => 'Incorrect email address ',
'filters' => [
[
'name' => 'StripTags',
],
[
'name' => 'StringToLower',
]
],
'validators' => [
[
'name' => 'EmailAddress',
'break_chain_on_failure' => true
]
]
],

cakephp show validation errors with jquery

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)?

Custom validation rule in CakePHP not working as intended

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;
}

CakePHP why am I getting this error?

Here is the error message:
Warning (2): preg_match() [http://php.net/function.preg-match]: Delimiter must not be alphanumeric or backslash [CORE/cake/libs/model/model.php, line 2611]
This is happening when I call the following code from my controller:
$this->Account->save($this->data)
The model looks like this:
class Account extends AppModel
{
var $validate = array(
'first_name' => array(
'rule' => array('minLength', 1),
'required' => true
),
'last_name' => array(
'rule' => array('minLength', 1),
'required' => true
),
'password' => array(
'rule' => array('minLength', 8),
'required' => true
),
'email' => array(
'emailRule1' => array(
'rule' => 'email',
'required' => true,
'message' => 'You must specify a valid email address'
),
'emailRule2' => array(
'rule' => 'unique',
'message' => 'That email address is already in our system'
)
)
);
}
I found a similar problem explained here
He solved it by changing required' => true to required' => array(true) I tried that for every occurange in my model but it did not fix the problem.
The problem was I named the rule unique it should be isUnique instead.
I would have figured this out much faster with a better error message.

CakePHP multirule validation

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')),
