Filters a meta value before it is saved to the database for any Groundhogg object. Use this to sanitise, validate, or transform custom meta values written by your extension.
apply_filters( 'groundhogg/sanitize_object_meta', $value, $key, $object_type, $original_value );
You will receive the sanitised value, the meta key string, the object type string (e.g. 'contact'), and the original unsanitised value.
Example
add_filter( 'groundhogg/sanitize_object_meta', 'my_extension_sanitize_meta', 10, 4 );
/**
* Enforce a maximum value for the loyalty_points meta key.
*
* @param mixed $value
* @param string $key
* @param string $object_type
* @param mixed $original_value
*
* @return mixed
*/
function my_extension_sanitize_meta( $value, $key, $object_type, $original_value ) {
if ( $key === 'loyalty_points' && $object_type === 'contact' ) {
return min( absint( $value ), 10000 );
}
return $value;
}
