Example 2 : Laravel Form Validation- Server Side form validation

Defining Routes

Route::get('sell', function(){
    return view('sell');
});
Route::post('sell', 'ProductController@sell');

Creating Sell Form

Fill the form to sell



Name  








product_code  








productminmax  








producttype
 


Male
 


Female






promo_code








Confirm promo_code

Creating the Controller

name = $req->name;
  $Product->product_code= $req->product_code;
  $Product->productminmax = $req->productminmax;
  $Product->producttype = $req->producttype;
  $Product->promo_code = $req->promo_code;

  $Product->save();

  echo "Product Created Successfully";

 }
}

Simple Laravel Validation Logic

validate($req, [
   'name' => 'required',
   'product_code' => 'required|product_code',
   'productminmax' => 'required|max:10|min:10',
   'producttype' => 'required',
   'promo_code' => 'required|confirmed',
   'promo_code_confirmation' => 'required',
  ]);
  $Product = new \App\Product;
  $Product->name = $req->name;
  $Product->product_code= $req->product_code;
  $Product->productminmax = $req->productminmax;
  $Product->producttype = $req->producttype;
  $Product->promo_code = $req->promo_code;

  $Product->save();

  echo "Product Created Successfully";

 }
}

Displaying All the Errors

@if (count($errors) > 0)
 

 

  @foreach ($errors->all() as $error)
   
{{ $error }}
  @endforeach
 
 
@endif

  },
  error: function(data){
   var errors = data.responseJSON;
   for(i in errors){
