   Struggling a bit here.

   I'm trying to add an array using add_option.

   When I try to access the array using get_option I'm not getting the results I expect.

   Here's a simple demo of my code:

   $test = array(
   'a' => 'b',
   'c' => 'd',
   'e' => 'f',
   );
   
   add_option('something', "$test");  // I've done the  	register_setting    bit earlier on
   
   $result = get_option("$test"); 
   
   print_r ($result);  // The output is     Array
   
   echo '<br />';
   
   echo $result ['e'];  // The output is  f

   I'm not quite sure why print_r ($result) is only returning 'Array'.

   I want to access $result using foreach but obviously I'm not being allowed to since apparently there's an empty array. :-)

   I'm 90% sure that when setting or retrieving the value, you need to remove the quote marks, since it's an array.

   In other words, change:

   add_option('something', "$test");

   to:

   add_option('something', $test);

   and change:

   $result = get_option("$test");

   to:

   $result = get_option($test);

   After that, you're right that you'll need to access the data with a foreach loop similar to this:

   foreach ($result AS $currentVal) {
     echo $currentVal . '<br />';
   }
