Install the gs_paragraphs module
Create a hook to add a file_managed type field on theme settings
Example:
/**
* Implements hook_form_system_theme_settings_alter().
*/
function test_form_system_theme_settings_alter(&$form, FormStateInterface $form_state) {
$form['custom_logo'] = [
'#type' => 'managed_file',
'#title' => t('Contact image'),
'#description' => t('Upload the contact image.'),
'#default_value' => theme_get_setting('contact_image'),
'#progress_indicator' => 'bar',
'#progress_message' => t('Please wait...'),
'#upload_location' => 'public://test',
];
$form['#submit'][] = 'test_theme_settings_form_system_theme_settings_submit';
}
/**
* Test theme form settings submission handler.
*/
function test_theme_settings_form_system_theme_settings_submit(&$form, FormStateInterface $form_state) {
if ($file_id = $form_state->getValue(['custom_logo', '0'])) {
$file = File::load($file_id);
$file->setPermanent();
$file->save();
}
}
