rwmb_set_meta
is a helper function that helps you to set meta value for an object.
To set meta value, use the following code:
rwmb_set_meta( $object_id, $field_id, $value, $args = [] );
Parameter | Description |
---|---|
$object_id |
Object (post, term, user) ID. If you need to set value for an option (using MB Settings Page), object ID is the option name. |
$field_id |
Field ID. |
$value |
Value. Should be compatible with field value format. See database. |
$args |
Extra arguments for some object types or storages. It works similarly in rwmb_meta function. Can be array or a string in format param1=value1¶m2=value2.Optional. |
Important Note
This function works only when the field is already registered. In Meta Box, fields are registered at hook init
with priority 20. So, you need to run this function after that:
add_action( 'init', function() {
rwmb_set_meta( 12, 'my_field', 'my_value' );
}, 99 );
