Hi,
I have create a description field and i want to call this in the header with this code :

// meta description 

function wpse_custom_meta_description() 
{

    if ( ! is_single() )
        return;

    $desc = get_field('meta_description');

    // Output
    if( ! empty( $desc ) )
        printf( 
            '<meta name="description" content="%s" />',
            esc_attr( trim( $desc ) )
        );
}
add_action( 'wp_head', 'wpse_custom_meta_description' , 2 );

 // meta description 

But $desc is umpty !

The code I created works very well, it will not pose any problem in the future is it right?
