function af_get in Arrange Fields 7

This is a helper function which will let me attempt to access indexes in an array which might not exist WITHOUT setting off a PHP Notice message in Drupal. A little kludgy? Perhaps, but I feel that it makes the code much more readable. For example, instead of: $x = (isset($GLOBALS["xyz"])) ? $GLOBALS["xyz"] : ""; I can just type: $x = af_get($GLOBALS["xyz"]); See what I mean? Much more simple and readable.

4 calls to af_get()

arrange_fields_add_draggable_wrappers in ./arrange_fields.module

In this function, we are going to add div's around elements we wish to make draggable on the page. The jQuery can then grab onto those divs to make them draggable.

arrange_fields_form_alter in ./arrange_fields.module

Implementation of hook_form_alter().

arrange_fields_page_alter in ./arrange_fields.module

arrange_fields_pre_render in ./arrange_fields.module

This function is called before the elements are displayed on screen. The main thing we wish to do here is move the contents of #af_prefix and #af_suffix into the real #prefix and #suffix fields.
