Permanently save file uploaded by a custom form's managed_file form element in Drupal 8/9/10

By hari, 4 January, 2023

Sometime we permanently lose custom form uploaded files after the cron run, this is due to the file status flag. Here is an example how to add custom form file upload permanently available on the website.

Here I created a sample form from FormBase, and added form element image with managed_file type.

<pre>
<code>
class AddBannerForm extends FormBase {


public function getFormId()
{
  return 'add_banner_form';
}

public function buildForm(array $form, FormStateInterface $form_state)
{


  $form['image'] = [
    '#type'          =&gt; 'managed_file',
    '#title'         =&gt; t('Choose Image File'),
    '#upload_location' =&gt; 'public://images/',
    '#default_value' =&gt; '',
    '#description'   =&gt; t('Specify an image(s) to display.'),
  ];

  $form['submit'] = [
    '#type' =&gt; 'submit',
    '#value' =&gt; t('Save image'),
  ];

  return $form;
}

public function submitForm(array &amp;$form, FormStateInterface $form_state) {
  /* Fetch the array of the file stored temporarily in database */ 
   $image = $form_state-&gt;getValue('image');

  /* Load the object of the file by it's fid */ 
   $file = File::load( $image[0] );

  /* Set the status flag permanent of the file object */
   $file-&gt;setPermanent();

  /* Save the file in database */
   $file-&gt;save();
}
</code>
</pre>
