WP_DEBUG is telling me:

Notice: Undefined index: no_cat_base in myplugin.php on line 20

Here's the lines of code where I'm pulling the value of "no_cat_base" from my options array called "myoptions"...

$myoptions = get_option('my_settings');

if($myoptions['no_cat_base']){//This is line 20}

Is the correct fix for this...

if ( isset($myoptions['no_cat_base'])){//do something}
  • Not 100% sure, but if you're expecting an array from your setting (i.e. you're pulling action_plugins setting from the database), I believe you have to cast it as an array?

  • Yes, its a multidimensional array.

just to be on the safe side use:

if (array_key_exists('no_cat_base', $myoptions) && isset($myoptions['no_cat_base'])){
//do your thing
  • isset is enough, no need for array_key_exists Feb 6, 2011 at 10:38
  • 1
    As i posted "just to be on the safe side", but yes isset is enough
