Learn CakePHP v3.5 Tutorial in HINDI for beginners (Part 24) Data Validation in CakePHP(Model)

Описание: In this video we have discussed about Data validation in cakePHP,Validation rules in cakePHP

By Writting our Validation we can specify these either in Controller or in Model.

Here, we will see rules in Model.

Steps to do:
=============
Just use this in Model:
use Cake\Validation\Validator;

Here is the complete code of Model:
===============

namespace App\Model\Table;

use Cake\ORM\Table;
use Cake\Validation\Validator;

class TestsTable extends Table{

public function validationDefault(Validator $validator){

//rules
$validator-requirePresence("email","create","Email Should be needed")
-add("email",[
"unique"=[
"rule"="validateUnique",
"provider"="table",
"message"="Email should be unique"
]
])
-requirePresence("password","create","Password is needed")
-requirePresence("confirm_password","create","Confirm Password is needed")
-add("confirm_password",[
"password_mismatch"=[
"rule"=["compareWith","password"],
"message"="Password didn't match"
]
])
;

return $validator;
}

}

How to use in Controller
====================
$this-loadModel("Tests");
$validation = $this-Tests-newEntity($req_data); // $this-request-data
$validationErrors = $validation-errors();
if(!empty($validationErrors)){
//errors
print_r($validationErrors);
}else{
// passed
echo "Successfully Passed";
}

If any errors comes then "$validation" stores all errors.

To read the documentation of all these best way to read from its File:
file: /vendor/cakephp/cakephp/src/Validation/Validator.php
