Menu icons

Hello,

I'm modifying the menu.module so that when the user adds a new menu item or edits an existing menu item, then will be able to upload a menu icon; so that the icon will be displayed along side with the text.

However I'm having difficulty uploading the icon.

I've added form elements to the menu_edit_item_form($mid = 0):

  $form['menu_icon_path'] = array(
    '#type' => 'textfield',
    '#title' => t('Path to menu item icon'),
    '#default_value' => t(''),
    '#description' => t('some text')
  );
  
  $form['menu_icon_upload'] = array(
    '#type' => 'file',
    '#title' => t('Upload menu item icon'),
    '#maxlength' => 40,
    '#description' => t("some more text."),
  );

In the function menu_edit_item_save($edit) I added the following check:

  // Check for a new uploaded menu item icon, and use that instead.
  if ($file = file_check_upload($edit['menu_icon_upload'])) {
  ....
  }

However, the above evaluates to false all the time.

When I dump $edit['menu_icon_upload'] all I get is the file name. But not the source directory it is to be picked up from.

I've read a lot about adding $form['#attributes'] = array('enctype' => "multipart/form-data"); but truth be told I have no idea where in the menu.module code I would have to add this line. When I add the line to the method menu_edit_item_form($mid = 0) I get a null value for $edit['menu_icon_upload'].

Any assistance is greatly appreciated.

Thanks,
