warning: Invalid argument supplied for foreach() in [...]\content_taxonomy_autocomplete.module on line 222.

Hi,

I use content taxonomy on a node whose I alter the node creation form with a node--form.tpl.php file.

I alter the render cause I use tabs module to render the form on several tabs, it use tabs_render() instead of drupal_render() to render the form into nice tabs.

The problem is that it brings a foreach problem into taxonomy_autocomplete module. It doesn't seems to alter functionnalities...

I think adding an if condition to make the loop only if $values is not empty would bring more security and avoid some php notice.

Here is a patch that apply on the 6.x beta 4 that avoid this problem.
