laravel form validation

gongpex · September 8, 2016

Hello everyone,

long time no see, I hope all you are fine,

I tried to create laravel form validation using this code :

on : app\http\Requests\ValidationRequest.php

<?php

namespace App\Http\Requests;

use Illuminate\Support\Facades\Input;
use App\Http\Requests\Request;
use DB;

class ValidationRequest extends Request
{
    /**
     * 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
     */
    public function rules()
    {
	    $username = Input::get('username');
		$password = Input::get('password');
		$tables = DB::table('admin')->where('password',$password)->where('username',$username)->count();
	
		if(count($errors) > 0) {
                   return [
                         'username' => 'required|min:3',
			 'password' => 'required',		 
                   ];
		} else if($tables == 0){
		   return ['db' => 'dberr'];
		}

    }
	
	public function messages()
{
    return [
        'username.required' => 'Username is required',
		'username.min' => 'Username at least 3 character length',
		'password.required'  => 'Password is required',
		'db.dberr' => 'Username or Password is wrong',
    ];
}
}

this my routes :

Route::get('post', 'AdminController@index');
Route::post('signin', 'AdminController@store');

Route::get('post/home', 'AdminController@home');
Route::get('post/addcategory', 'AdminController@addcategory');

this is my controller : (AdminController.php)

<?php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Input;
use App\Http\Requests\ValidationRequest;
use App\Http\Controllers\Controller;
use DB;

  class AdminController extends Controller {
	 
    public function index()
    {
        return view('admin.admin',['db'=>null]);
    }

	
	/* laravel message and form validation */
	public function rules() {}
	public function messages() {}
	
	public function store(ValidationRequest $request){
	    
		//echo $tables;
	}
	
  }
  
  
/* 
 * To change this license header, choose License Headers in Project Properties.
 * To change this template file, choose Tools | Templates
 * and open the template in the editor.
 */

and this is my view :

<body>
  
    <form method="post" action="{{URL::to('signin')}}">
		   <div class="f_wrapper">
		    {{ $errors->first('db') }}
		    <div class="admin_panel">Store login</div>
			 <div> </div>
		     <div class="f_col">Admin Username</div><div class="f_col"><input name="username" type="text" class="inbox"></div>
			 <div class="f_col_w"><span class="number">{{ $errors->first('username') }}</span></div>
			 
			 <div class="f_col">Password</div><div class="f_col"><input name="password" type="password" class="inbox"></div>
			 <div class="f_col_w"><span class="number">{{ $errors->first('password') }}</span></div>
			 
			 <div class="f_col"> </div><div class="f_col"><a><input type="submit" value="Sign In"></a></div>
             <div class="f_col_w" style="height:10px;"> </div>
		   </div>   
    </form>

</body>

You need to explain what you mean when you say it doesn't work. You've been here long enough to know that saying it doesn't work tells us nothing about the problem.

ugh sorry yesterday I was drunk when post on this forum,

alright this is about how to make custom validator on laravel.

I had renew my code after search on google :

on controller (AdminController.php)

namespace App\Http\Controllers;

use Validator;

use Illuminate\Http\Request;

use Illuminate\Support\Facades\Input;

use App\Http\Requests\CreateUserRequest;

use App\Http\Controllers\Controller;

use DB;

public function postForm(CreateUserRequest $request) { return 'Success!'; }

on routes :

Route::post('signin', 'AdminController@postForm');

and on view :

 <form method="post" action="{{URL::to('signin')}}">
      <div class="f_wrapper">
	 @if ($errors->any())
	    <ul>{!! implode('', $errors->all('<li style="color:red">:message</li>')) !!}</ul>
	 @endif
		    
      <div class="f_col">Admin Username</div><div class="f_col"><input name="username" type="text" class="inbox"></div>
      <div class="f_col_w"><span class="number">{{ $errors->first('username') }}</span></div>
</form>

and this is on appServiceProvider.php :

<?php

namespace App\Providers;

use Validator;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
       Validator::extend('foo', function($attribute, $value, $parameters) {
            return substr($value, 0, 3) == '+44';
        });
    }

    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

and this is on http request :

<?php

namespace App\Http\Requests;

use Illuminate\Support\Facades\Input;
use App\Http\Requests\Request;
use DB;

class CreateUserRequest extends Request
{
    /**
     * 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
     */
    public function rules()
    {
	    return [
	      'username' => 'required|foo',
	    ];
    }

}

This custom validator expect if you put number on input field it's should be start +44,

here is the error : if I put field empty, the error message will be shown --this is ok (use laravel default validator),

but if I input random number not start with +44, it will cause error like this :

BadMethodCallException in Validator.php line 2694:

Method [validateFoo] does not exist.

Please someone help me

thanks

Note : please ignore post that I've made before, because I made it when I was drunk.....

Are you adding that validator correctly in the boot method, and are you sure that boot is getting called? It sounds like the validator function isn't defined.
