I created a custom Flickr Widget for Wordpress and successfully set up an options form for users to enter their Flickr information, but I cannot get the checkbox in the form to save whether or not it is checked. Any help would be greatly appreciated! Here are my widget(), form(), and update() functions:

function widget($args, $instance) {
extract($args);

$title = apply_filters('widget_title', $instance['title']);
$displaynum = $instance['displaynum'];
$flickrid = $instance['flickrname'];
$num = 6;
$feed = new SimplePie($instance['feed']);
$feed->handle_content_type(); 
$photostream = $instance['show_photostream'];


function update($new_instance, $old_instance) {
$instance = $old_instance;

$instance['title'] = strip_tags($new_instance['title'] );
$instance['displaynum'] = strip_tags($new_instance['displaynum'] );
$instance['feed'] = $new_instance['feed'];
$instance['flickrname'] = $new_instance['flickrname'];
$instance['show_photostream'] = (bool) $new_instance['show_photostream'];

return $instance;
}

function form($instance) {
$defaults = array (
    'title' => 'My Recent Flickr Uploads',
    'displaynum' => 6,
    'feed' => 'http://api.flickr.com/services/feeds/photos_public.gne?id=33927859@N06&lang=en-us&format=rss_200',
    'flickrname' => 'rastajellyfish',
    'show_photostream' => isset( $instance['show_photostream'] ) ? (bool) $instance['show_photostream'] : false
);
$instance = wp_parse_args( (array) $instance, $defaults); ?>

Any help would be greatly appreciated!!!

I would do:

function update($new_instance, $old_instance) {
    ...

    $instance['show_photostream'] = $new_instance['show_photostream'];

    return $instance;
}

function form($instance) {
    $defaults = array (
        ...
        'show_photostream' => !empty( $instance['show_photostream'] ) ? $instance['show_photostream'] : false
    );
    $instance = wp_parse_args( (array) $instance, $defaults);

  • hmmm...there seems to still be a problem. I'll still check the checkbox in the widgets page, the save process works fine, but the value of the checkbox is not retained and always reverts to being unchecked. Sep 3, 2010 at 14:53
