Order custom fields alphabetically

Question

I've been trying to order the custom fields alphabetically, but I can't get the ordered list I want... this is the code I'm using:

<?php 
        $vMarca = get_field('tienda_marcas'  , false, false);
        $post_objects = get_posts(array(
            'post__in'   => $vMarca,
            'order'   => 'ASC'  ,
            'orderby'   => 'title'  
        ));

        if($vMarca)
        {
            echo '<ul>' ;
            foreach($vMarca as $post_objects)
            {
                echo '<li>'  . $post_objects . '</li>' ;
            }
            echo '</ul>' ;
        }

        ?>

I need the custom fields to be ordered alphabetically.

It looks like you're trying to output the wrong stuff. You've ordered the $post_objects, not the $vMarca. Try using the $post_objects variable for your if and foreach statements thus:

<?php 
    $vMarca = get_field('tienda_marcas'  , false, false);
    $post_objects = get_posts(array(
        'post__in'   => $vMarca,
        'order'   => 'ASC'  ,
        'orderby'   => 'title'  
    ));

    if($post_objects)
    {
        echo '<ul>' ;
        foreach($post_objects as $post)
        {
            setup_postdata($post); ?>
            <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
            <?php the_content(); ?>
        }
        echo '</ul>' ;

    ?>
