    Hi All,
    I’ve searched on this one and can find nothing. Any help would be gratefully appreciated

    I’ve this code to get a image from a custom field

    <?php
	$values = get_post_custom_values("miniatura");
	if (isset($values[0])) {
?>
<a href="<?php the_permalink() ?>" rel="bookmark" title="link permanente para <?php the_title(); ?>"><img src="<?php bloginfo('template_url'); ?>/miniatura/<?php $values = get_post_custom_values("miniatura"); echo $values[0]; ?>" alt="" /></a>
      <?php } ?>

    and this works fine. The post load the image and the css.

    The problem!? How can I make the post print the image and the css only if there is a custom field?

    Can someone help me??

  • I don’t know if I understand what you need, but from what I can tell, the piece of code you wrote above will ouput nothing when the custom field is empty…

    No?

    The “if” condition if (isset($values[0])) make the link and the img tag appear only if there is something in $value… If no, it does nothing…

    True indeed.
    The problem it’s that on a post without the custom field the css still gets printed making appear a blank space on the posts.

    Maybe its not a problem after all and only a bad css coding.

    Well, put the your css in your code… ??

    Then, it will relative to the condition just like the img tag

    <?php
	$values = get_post_custom_values("miniatura");
	if (isset($values[0])) {
?>
-------> <div class for your image>
<a href="<?php the_permalink() ?>" rel="bookmark" title="link permanente para <?php the_title(); ?>"><img src="<?php bloginfo('template_url'); ?>/miniatura/<?php $values = get_post_custom_values("miniatura"); echo $values[0]; ?>" alt="" /></a>
-------> </div class for your image>
      <?php } ?>
