Draw Service type for particular post
In here we add meta information to posts. Posts can be either:
- Fire
- Snow
- Thunder
- Cold
- Wind
- Water
WordPress Dashboard can hold that info inside $meta_box_value like this:
function _draw_services(){
global $post;
$meta_box_value = get_post_meta($post->ID, 'service', true);
if(1 == $meta_box_value)
echo '<input type="radio" checked="checked" name="service" value="1" /> Fire';
else
echo '<input type="radio" name="service" value="1" /> Fire';
if(2 == $meta_box_value)
echo '<input type="radio" checked="checked" name="service" value="2" /> Snow';
else
echo '<input type="radio" name="service" value="2" /> Snow';
if(3 == $meta_box_value)
echo '<input type="radio" checked="checked" name="service" value="3" /> Thunder';
else
echo '<input type="radio" name="service" value="3" /> Thunder';
if(4 == $meta_box_value)
echo '<input type="radio" checked="checked" name="service" value="4" /> Cold';
else
echo '<input type="radio" name="service" value="4" /> Cold';
if(5 == $meta_box_value)
echo '<input type="radio" checked="checked" name="service" value="5" /> Wind';
else
echo '<input type="radio" name="service" value="5" /> Wind';
if(6 == $meta_box_value)
echo '<input type="radio" checked="checked" name="service" value="6" /> Water';
else
echo '<input type="radio" name="service" value="6" /> Water';
}
Action add_meta_boxes can take our function _services metabox to a post.
add_action( 'add_meta_boxes', 'add_custom_metaboxes');
/*add custom meta boxes function*/
function add_custom_metaboxes() {
// the next line is for playlists only for adding custom metabox for playlists!
$post_id = $_GET['post'] ? $_GET['post'] : $_POST['post_ID'] ;
/*post*/
add_meta_box(
'_services',
'Select the service type',
'_draw_services',
'post'
);
}
on post update we need to manage:
$service = $_POST['service'];
update_post_meta($post_id, 'service', $service);
Final output:
