In this post, I am going to cover A to Z about Laravel Validation.
Things we will talk about in this post.
After Installing Laravel we will create a sample form to see our validation.
1 - Create Form
To create form in resources/views folder create a view file form.blade.php.
@extends('app') @section('content') <!-- Container (Contact Section) --> <div id="contact" class="container"> <h3 class="text-center">Create User</h3> <p class="text-center"><em>Register Here</em></p> <div class="row"> <div class="col-md-12"> <div class="row"> <div class="col-sm-6 form-group"> <input class="form-control" id="name" name="name" placeholder="Full Name" type="text" required> </div> <div class="col-sm-6 form-group"> <input class="form-control" id="email" name="email" placeholder="Email" type="email" required> </div> </div> <div class="row"> <div class="col-sm-6 form-group"> <input class="form-control" id="gender" name="gender" placeholder="Gender" type="text" required> </div> <div class="col-sm-6 form-group"> <input class="form-control" id="password" name="password" placeholder="Password" type="password" required> </div> </div> <div class="row"> <div class="col-md-12 form-group"> <button class="btn pull-right" type="submit">Send</button> </div> </div> </div> </div> </div> @endsection 2 - Create Validation
To create validation Rule write inside controller
$request->validate([ 'name' => 'required', 'email' => 'required', 'gender' => 'required', 'password' => 'required', ]); To Display the error message on Input Fields
@error('name') <span class="text-danger">{{$message}}</span> @enderror 3 - Create Validation Using Validator Facade
To create validation using Validator Facade we can write in controller
$validate = Validator::make($request->all(), [ 'name' => 'required|min:5', 'email' => 'required', 'gender' => 'required', 'password' => 'required', ],[ 'name.required' => 'Name is must.', 'name.min' => 'Name must have 5 char.', ]); if($validate->fails()){ return back()->withErrors($validate->errors())->withInput(); } 4 - Create Request File For Validation
To Create a Request File we have to run a command
php artisan make:request FormDataRequest This will create a file inside App\Http\Requests folder.
The file will be like.
<?php namespace App\Http\Requests; use Illuminate\Foundation\Http\FormRequest; class FormDataRequest extends FormRequest { /** * Determine if the user is authorized to make this request. * * @return bool */ public function authorize() { return true; } /** * Get the validation rules that apply to the request. * * @return array<string, mixed> */ public function rules() { return [ 'name' => 'required|min:5', 'email' => 'required', 'gender' => 'required', 'password' => 'required', ]; } public function messages() { return [ 'name.required' => 'Name is Must', 'name.min' => 'Name Must be 5 Chr.', ]; } } Here you will get complete video tutorial on Youtube.
If you face any issues while implementing, please comment your query.
