My custom Meta Box has a drop down field, but how do I set the default Option Value to be blank? It is currently populating via the CPT's meta_value, but I'd like that to change.
Here's a screenshot of the issue:
I want the first option for the Second Author field to be blank/have no selection.
Code for Meta Box:
case 'select' :
$author_select_query = new WP_Query(array(
'post_type' => 'people',
'tax_query' => array(
'relation' => 'OR',
array(
'taxonomy' => 'role',
'field' => 'slug',
'terms' => array('adjunct-faculty'),
),
array(
'taxonomy' => 'role',
'field' => 'slug',
'terms' => array('faculty'),
)
),
'meta_key' => 'ecpt_people_alpha',
'orderby' => 'meta_value',
'order' => 'ASC',
'posts_per_page' => '-1'));
$authors = $author_select_query ->get_posts();
echo '<select name="', $field['id'], '" id="', $field['id'], '">';
foreach($authors as $author) {
echo '<option value="' . $author->ID . '"', $meta == $author->ID ? ' selected="selected"' : '', '>', $author->post_title, '</option>';
}
echo '</select>';
