Low Variables Select Entries Throws PHP Notice

TJ Draper 9 May 2017 13:33 question,

This could be some artifact of upgrading from EE 2 to EE 3, I don't know. I was getting a PHP notice coming from vt.low_select_entries.php: 

array_filter() expects parameter 1 to be array, string given. 

 user/addons/low_variables/types/low_select_entries/vt.low_select_entries.php, line 278


On line 278, $this->settings('categories') was a string rather than an array.

I fixed the notice by doing this: 

$categories = $this->settings('categories'); 
 $categories = is_array($categories) ? $categories : array(); 
 $categories = array_filter($categories);


I don't know if there's a better way or a root cause somewhere else.

    Weird. Did the notice not go away after saving the settings?
