Meta Box

Hi Thomas,

The background field saves details into an array. If you use the helper function rwmb_meta() to get its value - you'll get an array.

To get the generated CSS for the background, please use the function rwmb_the_value().

This is the sample code:

$bg = rwmb_meta( 'field_id' );
echo $bg['color']; // Output a single background attribute

// Get CSS for background
$css = rwmb_the_value( 'field_id', '', '', false );
echo $css;

Hey guys. Thanks a lot for your details. Let me check Jason's code first. Looks like it's more complicated than I thought.

Hi, to combine values of 2 fields when saving, please use this snippet:

add_action( 'rwmb_after_save_post', function( $post_id ) {
    if ( isset( $_POST['field_1'] ) && isset( $_POST['field_2'] ) ) {
        $value = $_POST['field_1'] . $_POST['field_2'];
        update_post_meta( $post_id, 'field_combine', $value );
    }
} );

This snippet combines the values of field_1 and field_2 into field_combine.

To add JS to a meta box, please use this snippet:

add_action( 'rwmb_enqueue_scripts', function() {
    wp_enqueue_script( 'your-script', 'https://url-to-your-js-file', array( 'jquery' ), '', true );
} ):

Hi,

Basically, the snippet change the post data before it's saved to the database. In this case, it set the comment status to closed for all submitted posts.

If you want to make a checkbox for toggling comment status, you can add a checkbox field to the meta box and change the condition to something like this:

// change
// if ( 'meta-box-id' == $config['id'] ) {
// to
if ( 'meta-box-id' == $config['id'] && !empty( $_POST['checkbox_id'] ) ) {

Hi,

This happens with an old date metabox that i created

Can you check the status of those meta boxes? Make sure they're published. You can check in the phpMyAdmin as well.

And i try to import metabox to a new fresh install but i cant. After try to import i am gettiong error like this: Cannot load meta-box-import.

Did you use the export/import functionality from the Builder?

Hi Charlin, I've just fixed the bug. I'll release new version now.

The easiest way is just set their IDs like: prefix-text and prefix-radio. Please just don't make something like field-one and field-one-two.

I'm working on fixing this bug. Until then, this is the only way to get rid off the bug.
