I am building a drupal 7 (7.20) website with a "project" content type which contains multiple image fields (i do not want to use galleries).
I would like to be able to perform a mass delete operation on these fields from the node edit page. From what I have gathered I have to override theme_file_widget_multiple and return a tableselect instead of a table and then use a button plus javascript to delete the images from the database.
Am I missing something obvious ? This seems like alot of work for something so trivial.
EDIT:
I have had some progress with this:
function mytheme_file_widget_multiple($variables) {
$element = $variables ['element'];
$headers = array ();
$headers ['info'] = t ( '' );
$widgets = array ();
foreach ( element_children ( $element ) as $key ) {
$widgets [] = &$element [$key];
}
usort ( $widgets, '_field_sort_items_value_helper' );
$rows [] = array ();
$i = 0;
foreach ( $widgets as $key => &$widget ) {
// Save the uploading row for last.
if ($widget ['#file'] == FALSE) {
$widget ['#description'] = $element ['#file_upload_description'];
continue;
}
$operations_elements = array ();
foreach ( element_children ( $widget ) as $sub_key ) {
if (isset ( $widget [$sub_key] ['#type'] ) && $widget [$sub_key] ['#type'] == 'submit') {
$operations_elements [] = &$widget [$sub_key];
}
}
$information = drupal_render ( $widget );
$rows [$i ++] ['info'] = $information;
}
$output = '';
$output = drupal_render_children ( $element );
$form ['element'] = array (
'#type' => 'tableselect',
'#header' => $headers,
'#options' => $rows,
'#js_select' => TRUE,
'#empty' => t ( 'No data' ),
'#attributes' => array () );
$output .= empty ( $rows ) ? "" : drupal_render ( $form );
return $output;
}
This was included in my theme's template file however the tableselect does not have checkboxes. This is driving me crazy.. Can someone please tell me what I am doing wrong ?
