Delete uploaded files after email has been send
When your WordPress form is submitted, delete any uploaded files directly after the email has been send.
Note: This code should no longer be used, you can now configure this via Super Forms > Settings > File Upload Settings
add_action('super_before_email_success_msg_action', '_super_delete_uploaded_files', 30, 1);
function _super_delete_uploaded_files( $atts ) {
// REPLACE 123 WITH YOUR FORM ID
$id = 123;
// CHANGE AND ADD THE NAMES OF FILE UPLOAD FIELDS
$fields = array(
'file1',
'file2',
'file3',
);
$form_id = absint($atts['post']['form_id']); // contains the form ID that was submitted
if( $form_id == $id ) {
$data = $atts['data']; // contains the submitted form data
foreach( $fields as $field_name ) {
if( isset( $data[$field_name]['files'] ) ) {
$files = $data[$field_name]['files'];
if( is_array( $files ) ) {
foreach( $files as $file ) {
wp_delete_attachment(absint($file['attachment']), true);
}
}
}
}
}
}
