rwmb_delete_meta

rwmb_delete_meta deletes the value of a field. It works with all storages: post meta, term meta, user meta, settings pages and custom tables.

Arguments

rwmb_delete_meta( $object_id, $field_id, $args = [] );

Parameter	Description
`$object_id`	Object (post, term, user) ID. For a settings page, use the option name.
`$field_id`	Field ID.
`$args`	Extra arguments, the same as in rwmb_meta, such as `object_type`. Optional.

The function returns true if the value is deleted, false if not. It returns false if the field is not registered.

warning

This function works only after the field is registered (hook init with priority 20). Run it after that, the same as rwmb_set_meta.

Delete a field value of a post:

rwmb_delete_meta( 123, 'subtitle' );

Delete a field value of a term:

rwmb_delete_meta( 15, 'color', [ 'object_type' => 'term' ] );

Delete a field value in a custom table:

rwmb_delete_meta( 123, 'price', [
    'storage_type' => 'custom_table',
    'table'        => 'wp_products',
] );
