Laravel 6 Ajax Form Validation Tutorial
In this Tutorial, i would like to guide how to use ajax form validation in laravel 6. we will use laravel 6 validation with ajax post request. we will gives errors response and display it on front side using ajax laravel 6.
Form validation is a basic requirement of any form. we should implement validation even if you use ajax or simple form. But if you are working with jquery ajax then you can use also server side validation using laravel and display error messages on front side.
You can simply use laravel 6 validation like required, email, same, unique, date, integer etc using jquery ajax post, get, put or delete request. we will use Validator make function for create validation and check using passes() function.
In this example i will show you how to use laravel default validation with jquery ajax. Here we also print laravel validation message when false. So if you want to ajax form validation in laravel app then you are right place.
Just follow bellow step to create ajax validation example:
Step 1: Add Route
In first step we will create new two routes for demo. so open your routes/web.php file and add following route.
routes/web.php
Route::get('my-form','HomeController@myform');
Route::post('my-form','HomeController@myformPost')->name('my.form');
Step 2: Create Controller
In this point, now we should create new controller as HomeController. So run bellow command and create new controller.
php artisan make:controller HomeController
After bellow command you will find new file in this path app/Http/Controllers/HomeController.php.
In this controller we will write three method for ajax view and post as listed bellow methods:
1)myform()
2)myformPost()
So, let's copy bellow code and put on HomeController.php file.
app/Http/Controllers/HomeController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Validator;
class HomeController extends Controller
{
/**
* Display a listing of the myform.
*
* @return \Illuminate\Http\Response
*/
public function myform()
{
return view('myform');
}
/**
* Display a listing of the myformPost.
*
* @return \Illuminate\Http\Response
*/
public function myformPost(Request $request)
{
$validator = Validator::make($request->all(), [
'first_name' => 'required',
'last_name' => 'required',
'email' => 'required|email',
'address' => 'required',
]);
if ($validator->passes()) {
return response()->json(['success'=>'Added new records.']);
}
return response()->json(['error'=>$validator->errors()->all()]);
}
}
