Final code seems to be different in WordPress 4.5

I'm working in WordPress 4.5 for all of these changes so the code that Zac uses to get this to work has changed.

Most of it is the same but there are a few changes from the code in the video, to the code in the project downloads and the code I used to get the dropdown settings to save. So for clarity. here is the code I used to get the dropdown menu setting to save in WordPress 4.5.

First, register the setting which is the same across all versions to date

register_setting( 'wpt_settings-group', 'wpt_select_test');


Then add the theme setting below the code for the other fields. Again this code has not changed.


        'Dropdown field',

Then in the callback function things start to change. Use the get options function as normal but as the paremamer use wpt_settings rather than wpt_select_test

function wpt_slideshow_select_callback() {

    $options = get_option( 'wpt_settings' );
    if( !isset( $options['wpt_select_test'] ) ) $options['wpt_select_test'] = 1;


There may well be other ways of solving the issue of this code discrepancies but this is what worked for me :)
