Support › General › File advanced rwmb_meta helper, array error
Hello, when I use rwmb_meta helper to get a link for file download into Oxygen repeater. I need to get just one file.
<?php $files = rwmb_meta( 'cf-den-1-ustanoveni', array( 'limit' => 1 ) ); $file = reset( $files ); ?> <a href="<?php echo $file['url']; ?>">Ustanovení</a>
I get the link on the frontend just fine, but backend reports this error reset() expects parameter 1 to be array, string given. Any thoughts on this?
Thank you.
Hi,
That means on the backend, the helper function gets the wrong third argument $post_id. You can try to put the post ID to the helper function and re-check it.
$post_id
$files = rwmb_meta( 'cf-den-1-ustanoveni', array( 'limit' => 1 ), 1234 );
Get more details on the documentation https://docs.metabox.io/rwmb-meta/#arguments
