   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. :)
