The correct code for saving the checkbox setting on the WordPress Settings API course.

Following on from my previous thread here, https://teamtreehouse.com/community/using-addthemepage yesterday thanks to this review video I was able to investigate and find the right code for saving the Checkbox setting.

It's actually available in the project downloads.

I followed the code exactly from the video and while the form field and label appeared, but the setting would not stay the same so it would clear the checkbox.

<?php  
function wpt_slideshow_checkbox_callback() {

    $options = get_option( 'wpt_show_slideshow' );  


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

    echo $html;

}

?>

However if I check the downloads for the same callback function this code as an added condition statement that checks the status of the checkbox setting and remembers the last setting when saved.

So for clarity, this is the one to use.

<?php 
function wpt_slideshow_checkbox_callback() {

    $options = get_option( 'wpt_settings' );    
    if( !isset( $options['show_slideshow'] ) ) $options['show_slideshow'] = 0;

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

    echo $html;

}


 ?>

Hi Konrad, Just to let you know your solution to the Checkbox issue not saving it's state is the only one across the entire web i've found that works! Cheers.
