There's a section of this lesson missing.

The lesson doesn't go over (skips) the part when the input variables are placed in the checkbox callback function.

This makes sense now. I was going back and forth trying to figure out why my checkbox wasn't showing.

Louis, I looked at the project downloads and paused the video in the right spot in the subsequent lesson to get the code I needed.

The Author really needs to go back and rectify this omission as this may cause unnecessary confusion. How about an addendum video focusing on the missed info? Zach? You listening?

Otherwise this course was great.

The rest of the input/label code can be found in the next video "Coding Out a Theme Options Page Setting Form" at 5:10 for a split second.

This issue still persists. It'd be useful if the snippet of code missing could at least be posted. Obviously the most helpful solution would be a video explaining the code as well but I understand that that would take some time. Gloria Dwomoh Zac Gordon

Here is the code he skipped over 

function wpt_slideshow_checkbox_callback() {

      $option = get_option('wpt_show_slideshow');

      $html = '<input type="checkbox" id="wpt_show_slideshow" value="1"' . checked(1, $option, false) .'/>';
      $html .= '<label for="wpt_show_slideshow">Check to enable slideshow on the homepage</label>';

      echo $html;

}

He makes a slight change to this code in the very next video.

Having just gone started this course myself in the last couple of days, my assumption was that Zac was going to introduce all of this code in the next video. https://teamtreehouse.com/library/wordpress-settings-api/creating-a-theme-options-page-settings/coding-out-a-theme-options-page-setting-form.

I'm a little confused as I never felt like anything has been missing out of place so far because even Zac says at this point we haven't actually coded anything that adds form fields to the page.

Here's a link to another thread that may help people with showing the form fields on the Theme Options page.

This is the code you need:

function wpt_slideshow_checkbox_callback() {

$option = get_option( 'wpt_show_slideshow' );

$html = '<input type="checkbox" id="wpt_show_slideshow" value="1"' . checked( 1, $option, false ) . '/>'; $html .= '<label for="wpt_show_slideshow">Check to enable Slideshow on the homepage</label>';

echo $html;

}
