Drupal file_validate_extensions для расширения вложения файла с использованием hook_form_alter
Я построил модуль, который изменяет форму с помощью функции под названием form_mods_form_alter. Я хочу разрешить только типы файлов jpg, jpeg, png. То, что я имею, не проверяет. Это позволяет GIF, и я не хочу, чтобы GIF.
<?php
function form_mods_form_alter($form, $form_state, $form_id) {
// Ad form
if($form_id == 'ad_node_form'){
$form['attachments']['wrapper']['new']['upload']['#description'] = 'BBGI test The maximum upload size is 1 MB. Only files with the following extensions may be uploaded: jpg jpeg png.';
$form['attachments']['wrapper']['new']['upload']['#ahah']['#upload_validators']['file_validate_extensions'][0] = 'png jpg jpeg';
}
}
?>
Вот что я получаю с помощью print_r($form);

Валидаторы загрузки должны идти на элемент, а не на #ahah имущество. Попробуй это:
$form['attachments']['wrapper']['new']['upload']['#upload_validators']['file_validate_extensions'][0] = 'png jpg jpeg';
