  • I’m getting this error too. In PHP < 5.6 (I think), the empty() function only accepts variables and not returns from another function.

    So what you need to do is change line 107 from:

    $tptn_settings[‘exclude_post_ids’] = empty( sanitize_text_field( $_POST[‘exclude_post_ids’] ) ) ? ” : implode( ‘,’, array_map( ‘absint’, explode( ‘,’, sanitize_text_field( wp_unslash( $_POST[‘exclude_post_ids’] ) ) ) ) );

    … to:

    $exclude_post_ids_value = sanitize_text_field( $_POST[‘exclude_post_ids’] );

    $tptn_settings[‘exclude_post_ids’] = empty( $exclude_post_ids_value ) ? ” : implode( ‘,’, array_map( ‘absint’, explode( ‘,’, sanitize_text_field( wp_unslash( $_POST[‘exclude_post_ids’] ) ) ) ) );

    Basically put the result of sanitize_text_field( $_POST[‘exclude_post_ids’] ) into a variable before you put it through empty().

    This might not be an issue on later versions of PHP, but will likely be required for backwards compatibility.

    Thanks for the fix. You could potentially directly use this on line 107.

    $tptn_settings['exclude_post_ids'] = empty( $_POST['exclude_post_ids'] ) ? '' : implode( ',', array_map( 'absint', explode( ',', sanitize_text_field( wp_unslash( $_POST['exclude_post_ids'] ) ) ) ) );
