function arrange_fields_get_form_fields in Arrange Fields 6

Same name and namespace in other branches

1. 7 arrange_fields.module \arrange_fields_get_form_fields()

This function uses recursion to go through an array (presumably $form). It will return back an array of references to fields which we might want to place wrappers around.

It is meant to be used by arrange_fields_add_draggable_wrappers().

Parameters

array $arr:

string $previous_key:

Return value

array

1 call to arrange_fields_get_form_fields()

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.

File

./arrange_fields.module, line 342

      // the entire buttons array, NOT each individual button (this was
      // causing a bug where Diff's View changes and the Delete button
      // were not arrangeable.
      if ($name == "buttons" && $element["#type"] == "" && $element["submit"]["#type"] == "submit") {

        // Okay, we found it (most likely, anyway).
        // Let's add it to our return array.

        // actually want to use the previous element.

        // and explore this new level.
