What’s the complete results for the print_r()? What you provided so far looks like just a portion.
It is also possible that it doesn’t, but I’d need some sort of test case data to tinker with and confirm.
here’s more code:
those are the complete results. if i select more options, however, it looks like this
Array ( [0] => new-orleans [1] => portland [2] => san-diego )
$vip_array = get_post_meta( get_the_ID(), '_rnr3_vip_dropdown', true );
print_r($vip_array );
serialized array looks like so:
a:3:{i:0;s:11:"new-orleans";i:1;s:8:"portland";i:2;s:9:"san-diego";}
Reading through this, I’m not sure I fully understand the request? Multicheck type saves an array of the values selected, like your debug demonstrates.
Side note, I would not do any queries to generate the options array for multicheck. It is far better if you create a callback and use the ‘options_cb’ to generate those results and do the query so that the query only happens when it’s needed (vs every page-load of the site).
// multicheck
$cmb->add_field( array(
'name' => 'Dropdown Events',
'id' => $prefix . 'vip_dropdown',
'type' => 'multicheck',
'options_cb' => 'get_updated_event_array',
'select_all_button' => false
) );
and
function get_updated_event_array() {
$event_array = $wpdb->get_results( "SELECT event_slug, event_location FROM DBNAME WHERE event_slug != 'series' ORDER BY event_location" );
$updated_event_array = array();
foreach( $event_array as $event ) {
$updated_event_array[ $event->event_slug ] = $event->event_location;
}
return $updated_event_array;
}
i guess i was trying to get a way to save a user’s option so that i could get 2 variables out of it.
if that’s not even possible, i’ll work on a diff way to do it…
the way i’m using it:
<?php
$vip_array = get_post_meta( get_the_ID(), '_rnr3_vip_dropdown', true );
// print_r($vip_array );
?>
<select id="selectrace">
<option value="box">-- Select a race --</option>
<?php foreach( $vip_array as $key => $value ) {
echo '<option value="'.site_url( $key.'/the-weekend/vip/') .'">'. $value .'</option>';
} ?>
</select>
** thanks for the sidenote, that’s helpful (i didn’t know it worked that way — always thought it only made the call on that page in the admin)
Yeah, looks like it’s not preserving the named indexes.
Is there a particular reason you’re needing the event slugs preserved? Curious if there’s a better field type for your use-case.
If you don’t want to do the DB lookup again based on the saved slug, you could always try to combine the value/label into the value field:
function get_updated_event_array() {
$event_array = $wpdb->get_results( "SELECT event_slug, event_location FROM DBNAME WHERE event_slug != 'series' ORDER BY event_location" );
$updated_event_array = array();
foreach( $event_array as $event ) {
$updated_event_array[ esc_attr( $event->event_slug . '::' . $event->event_location ) ] = $event->event_location;
}
return $updated_event_array;
}
and
foreach ( $saved_values as $value ) {
list( $slug, $location ) = explode( '::', $value );
}
love that solution, justin!
thanks!
