You can simply use laravel 5.8 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.
It will be always great if you use laravel validation for your web form in laravel 5.8 project. we can use laravel validation very simply if we don't need to use jquery ajax. because laravel provide easy way to use validation without ajax. But if you want to use laravel validation with jquery then you can't do it easily. However you can make it by following example.
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');
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
<?phpnamespace 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()]);}}
Step 3: Create View File
In Last step, let's create myform.blade.php(resources/views/myform.blade.php) for layout and we will write design code and jquery ajax code,so put following code:
resources/views/myform.blade.php
