PHP warning: low_select_entries/vt.low_select_entries.php, Invalid argument supplied for foreach()

Tim Kelty 12 Jan 2012 23:27 problem, complete

Severity: Warning
Message: Invalid argument supplied for foreach()
Filename: low_select_entries/vt.low_select_entries.php
Line Number: 258

It would seem this->EE->api_channel_categories can also return FALSE in some cases, causing this warning

   Hi Tim,
   
   Thanks for reporting. You can replace that code block (the foreach loop) with this:
   
   

   if ($tree = $this->EE->api_channel_categories->category_tree($group_id)) 
    { 
     foreach ($tree AS $cat) 
     { 
      $indent = ($cat[5] > 1) ? str_repeat(NBS.NBS, $cat[5]) : ''; 
      $select[$cat[0]] = $indent.$cat[1]; 
     } 
    }

   
   
   ...which I'll add to the core.

   v2.0.2 should fix this issue.
