Question

I’m displaying a custom field like this:

<div class="blog_text">
    <img src="<?php the_field('imagen_prensa'); ?>" />
</div>

I would like to make the img appear only if the user has uploaded an image, because right now if there is no image then a broken image symbol appears.

I have tried the following, but it did not work:

<?php if (get_field('imagen_prensa') != ''): ?>
     <img src="<?php the_field('imagen_prensa'); ?>" />
<?php endif; ?>

Any can this be achieved?

EDIT:

this is the code now using the answers below but now it gives just a blank page:

<div id="blog_interior">

        <?php /* Start the Loop */ ?>
        <?php while ( have_posts() ) : the_post(); ?>

            <article>
            <div class="article_date"><?php the_time('d/m/Y'); ?></div>
            <h2><?php echo get_the_title(); ?></h2>
            <div class="blog_text">
                <?php if ( !empty(the_field('imagen_prensa')) ): ?>
                    <img src="<?php echo the_field('imagen_prensa'); ?>" />
                <?php endif; ?>
                <div class="video_prensa"><?php the_field('video_prensa'); ?></div>
                <?php the_content() ?>
            </div>
        </article>

        <?php endwhile; ?>    
            <div class="back">

            </div>
    </div>

You forgot the echo to actually print the result of the_field(‘imagen_prensa’).

Use this:

<?php if ( !empty(the_field('imagen_prensa')) ): ?>
     <img src="<?php echo the_field('imagen_prensa'); ?>" />
<?php endif; ?>

I’ve edited your code, to something which seems a bit more logical also added echo’s where they were missing. I’m not used to these constructions:

<?php while ( have_posts() ) : the_post(); ?>

So I’m not actually sure if it’s working properly or not, but you could check what these variables output by surrounding them with a var_dump like var_dump(have_posts());

Your edited code:

<div id="blog_interior">

    <?php /* Start the Loop */ ?>
    <?php foreach( $posts as $post ): ?>

        <div class="article_date"><?php echo the_time('d/m/Y'); ?></div>
        <h2><?php echo get_the_title(); ?></h2>
        <div class="blog_text">
            <?php if ( !empty(the_field('imagen_prensa')) ): ?>
                <img src="<?php echo the_field('imagen_prensa'); ?>" />
            <?php endif; ?>
            <div class="video_prensa"><?php the_field('video_prensa'); ?></div>
            <?php echo the_content() ?>
        </div>

    <?php endforeach; ?>    
    <div class="back">

    </div>
</div>
