How do I get all options from a custom fields select, and render a drop down on the frontend from it with the exact same values as is displayed in the backend?
For the sake of needing this at a later point:
$field_key = "field_5925c714d03e7"; // <-- Find this by turning on Field Keys under Screen Options in admin interface
$field = get_field_object($field_key);
if( $field ) {
echo '<select id="brands" name="brands" class="brands" autocomplete="off">';
echo '<option value="-1">All</option>';
foreach( $field['choices'] as $k => $v ) {
echo '<option value="' . $k . '"';
if ( $k == $brand ) {
echo ' selected';
}
echo '>' . $v . '</option>';
}
echo '</select>';
}
This demonstrates a good use of get_field_object(). Until I found this I was maintaining a separate lookup table in PHP because I couldn’t figure out a way of reading select labels from values on front-end pages without a result set.
Kudos to @blaasvaer for sharing this.
