Widget Checkbox Group – not registering.

  • Hi,
    I’m having difficulties getting my checkboxes to save in a widget I’m developing. I’m pulling out the categories and displaying them as checkboxes, but I want them as a group as opposed to individual.

    Saving checkbox group value using below –
    $instance['gallerycats[]'] = isset($new_instance['gallerycats[]']);

    Displaying the checkboxes as follows –

    $categories=  get_categories();
foreach ($categories as $cat) {

$option='<input type="checkbox" id="'. $this->get_field_id( 'gallerycats[]' ) .'" name="'. $this->get_field_name( 'gallerycats[]' ) .'"';
					if (is_array($instance['gallerycats[]'])) {
					foreach ($instance['gallerycats[]'] as $cats) {
					if($cats==$cat->term_id) {
					$option=$option.' checked="checked"';
					}
					}
					}
					$option .= ' value="'.$cat->term_id.'" />';

                    $option .= $cat->cat_name;
                    $option .= ' ('.$cat->category_count.')';
                    $option .= '<br />';
                    echo $option;
                  }

    Thanks in advance!

    Sorted.

    Place the [] outside of the variable.

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

    $categories=  get_categories();
foreach ($categories as $cat) {
	$option='<input type="checkbox" id="'. $this->get_field_id( 'gallerycats' ) .'[]" name="'. $this->get_field_name( 'gallerycats' ) .'[]"';
					if (is_array($instance['gallerycats'])) {
					foreach ($instance['gallerycats'] as $cats) {
					if($cats==$cat->term_id) {
					$option=$option.' checked="checked"';
					}
					}
					}
					$option .= ' value="'.$cat->term_id.'" />';

                    $option .= $cat->cat_name;
                    $option .= ' ('.$cat->category_count.')';
                    $option .= '<br />';
                    echo $option;
                  }

    Thanks for posting your own solution. It helps those of us who are doing the same thing, yet it’s something many people leave unattended after they solve. ??
