I have a custom meta box. In it there are input fields, as well as a select box. What I want, is to have the get_tags array list to be outputted as the values in the select box.
I currently have the select box option values hard coded. I want this to be dynamic depending on the tags on the website.
Here is the code;
// Add the Meta Box
function spk_project_info_meta_box() {
add_meta_box(
'spk_project_info_meta_box', // $id
'Project Information', // $title
'show_spk_project_info_meta_box', // $callback
'post', // $page
'normal', // $context
'default'); // $priority
}
add_action('add_meta_boxes', 'spk_project_info_meta_box');
// Field Array
$prefix = 'spk_project_info_';
$tags_array = get_tags();
$custom_meta_fields = array(
array(
'label'=> 'Client',
'desc' => 'A description for the field.',
'id' => $prefix.'client',
'type' => 'text'
),
array(
'label'=> 'Our Role',
'desc' => 'A description for the field.',
'id' => $prefix.'role',
'type' => 'text'
),
array(
'label'=> 'Year',
'desc' => 'A description for the field.',
'id' => $prefix.'year',
'type' => 'text'
),
array(
'label'=> 'Select Box',
'desc' => 'A description for the field.',
'id' => $prefix.'select',
'type' => 'select',
'options' => array (
'one' => array (
'label' => 'Option One',
'value' => 'one'
),
'two' => array (
'label' => 'Option Two',
'value' => 'two'
),
'three' => array (
'label' => 'Option Three',
'value' => 'three'
)
)
)
);
// The Callback
function show_spk_project_info_meta_box() {
global $custom_meta_fields, $post;
echo '<input type="hidden" name="spk_project_info_meta_box_nonce" value="'.wp_create_nonce(basename(__FILE__)).'" />';

You can do it like so — replace the $tags_array = get_tags(); with this:
$tags_opt = array();
foreach ( get_tags() as $term ) {
$tags_opt[] = array(
'label' => $term->name,
'value' => $term->term_id,
);
}
And then, for the "Select Box" field, set the options to $tags_opt like this:
array(
'label' => 'Select Box',
...
'options' => $tags_opt,
)
If you want to save the term/tag slug instead of its ID (term_id), change the 'value' => $term->term_id to 'value' => $term->slug.
And if you want to include tags without any posts, use get_tags( array( 'hide_empty' => 0 ) ).
