This is my Route. I use resource with TaskController class

Route::resource('main',TaskController::class);

This is my post form in main.blade.php. I know laravel post form must input $crsf

 <form action="" method="post" enctype="multipart/form-data"">
    @csrf
    @method('POST')
  <input type="file" hljs-string">"name="img" accept="image/*">
  <button  name="upload" type="submit" value="ok">Button</button>
  </form>

Here is my TaskController. I use function index() and try to delete process if it shows blankpage agian

When I submit my form laravel shows black page. Where may be the problem?

CodePudding user response：

The action attribute in form tag is blank. Change it to the corresponding route

CodePudding user response：

You need to set the action on the form to match your Resource:

   <form action="/main" method="post" enctype="multipart/form-data"">

And after that if you post to that endpoint the controller function that will be invoked is store. Documentation

CodePudding user response：

I have found a solution. I changed the following route:

Route::resource('/main',TaskController::class);

to

Route::get('/main',[TaskController::class,'index']);
Route::post('/main',[TaskController::class,'index']);
