Re: Cakephp 3.x Validation Error issue

Hi John,

I am working on form builder here you can see the image

https://www.dropbox.com/s/tefh2auwqy97g10/form_builder.png?dl=0

It is working in cakephp 2.x fine. here are answers of your questions.

Have you studied the CakePHP book?

yes I read the cakephp 3.x cook book

What have you tried?

In cakephp 2.x I have written validations like following but I have no idea how to try multiple index validation in cakephp 3.x

Cakephp 2.x Form fields are 

$this->Form->input('FormElement.text.1.title', ['type'=>'text', 'label'=>false, 'class'=>'form-control']);

$this->Form->input('FormElement.text.2.title', ['type'=>'text', 'label'=>false, 'class'=>'form-control']);

Cakephp 2.x Model Validations are

public $validate = array(

   'text'=> array(

'mustNotEmpty'=>array(

'rule' => 'checkForText',

'message'=> '',

'last'=>true)

),

'textarea'=> array(

'mustNotEmpty'=>array(

'rule' => 'checkForTextarea',

'message'=> '',

'last'=>true)

)

);

function checkForText() {

if(!empty($this->data['FormElement']['text'])) {

foreach($this->data['FormElement']['text'] as $key=>$val) {

if(empty($val['title'])) {

$this->validationErrors['text'][$key]['title'] = "Please enter title";

}

}

}

return true;

}

function checkForTextarea() {

if(!empty($this->data['FormElement']['textarea'])) {

foreach($this->data['FormElement']['textarea'] as $key=>$val) {

if(empty($val['title'])) {

$this->validationErrors['textarea'][$key]['title'] = "Please enter title";

}

}

}

return true;

}

so the validation work like a charm on multi index input fields 'FormElement.text.1.title' etc. The form fields are dynamically added.

I am not getting any clue to convert this code in cakephp 3.x

What does not work?

In cakephp 3.x I have tried so far.

Cakephp 3.x Form fields are 

$this->Form->input('FormElements.text.1.title', ['type'=>'text', 'label'=>false, 'class'=>'form-control']);

$this->Form->input('FormElements.text.2.title', ['type'=>'text', 'label'=>false, 'class'=>'form-control']);

Cakephp 3.x Model Validations are

public function validationForFormElements($validator) {

$validator

->add('text', [

'mustNotEmpty'=>[

'rule'=>'checkForText',

'provider'=>'table',

'message'=>''

]

])

->add('textarea', [

'mustNotEmpty'=>[

'rule'=>'checkForTextarea',

'provider'=>'table',

'message'=>''

]

]);

return $validator;

}

function checkForText($value, $context) {

if(!empty($context['data']['text'])) {

foreach($context['data']['text'] as $key=>$val) {

if(empty($val['title'])) {

I have no idea how add validation error on particular index

}

}

}

return true;

}

function checkForTextarea($value, $context) {

if(!empty($context['data']['textarea'])) {

foreach($context['data']['textarea'] as $key=>$val) {

if(empty($val['title'])) {

I have no idea how add validation error on particular index

}

}

}

return true;

}

Do you get any error messages?

I did not get any error messages

Please let me know if anything is not clear.

Please show the validation code you have tried, the code for the form and whatever else that may help us understand your problem.
