My Drupal version is 8.6.10

I am trying to upload a file through the file_save_upload function and the function is looking for the file in

Symfony\Component\HttpFoundation\FileBag Object

$all_files = \Drupal::request()->files; debug($all_files); Symfony\Component\HttpFoundation\FileBag Object ( [parameters:protected] => Array ( ) )

But my file is in

Symfony\Component\HttpFoundation\ParameterBag Object.

$all_files = \Drupal::request()->request; debug($all_files); Symfony\Component\HttpFoundation\ParameterBag Object ( [parameters:protected] => Array ( [name] => [type] => 4 [files] => Array ( [image_section] => logo_capnord.png ) [op] => Ajouter [form_build_id] => form-wMTrCGaN5mPlOOv8bqS7UsJ0lRiSN6QQp9UviA0cTIA [form_token] => 1hTMXJRfoQvFV9Lqq3TuJ29eYC6L-zt3U7Bow1P8yJ0 [form_id] => capnord_section_form_list ) )

The field is generated through the reloading of the form in ajax.

 $form["base"]["fields"] += [ "image_section" => [ "#type" => "file", "#title" => "Image", ] ];

  • I solved my problem, as I only reloaded one part of the form, the form generator did not know that there was a file element, so it did not add "multipart enctype / form-data" to the form. Commented Mar 14, 2019 at 14:30

Solution

$form["#attributes"] = ["enctype" => "multipart/form-data"]; $form["base"]["fields"] += [ "image_section" => [ "#type" => "file", "#title" => "Image", ] ];

I hope this will help someone in the same situation as me in the future.
