file upload loop doesn’t return empty if no file is uploaded

    I have a file upload where I input an attachment and it will be echoed as a link on the frontend.

    On the post edit window, when I accidentally press the “+” button to add a loop but without uploading anything, in the output, it will still echo text, but without the source.

    I’ve tried a lot of things but nothing worked:

    if ( $theloop ) :

    if ( ! empty ($theloop ) ) :

    if ( $theloop != '' ) :

    if ( $theloop ) :

    How can I test if the added loop doesn’t have anything on it?

    here’s my full code:

    <?php $theloop = CFS()->get('file_upload');

    if ( ! empty ($theloop ) ) : foreach ( $theloop as $thefile ) {

    		$thesource= $thefile ['upload_file'];?><a>EN</a> ?>

    <?php}endif;?>

    Your foreach() and empty() may need to be reversed…

    
foreach ( (array) $theloop as $thefile ) {
    if ( ! empty( $thefile ) ) {
        // do something
    }
}
