conditional tag - show custom field only if has value? - ad2003 - 2012-11-23
Hi there!
Has anybody an idea how to get content only be shown as custom field has value?
e.g: I am using GS Blog Custom Fields, I have a custom field calles "pic1"
I want to have some images within a class like:
<img class="thumbnail" src="<?php echo $post->pic1; ?>" width="100" height="80" alt="" title="" />
But if theres no custom field value I don't want to have the class and stuff to be loaded.
I tried something like this:
<?php if ($post->pic1, TRUE) { ?> <img class="thumbnail" src="<?php echo $post->pic1; ?>" width="100" height="80" alt="" title="" /> <?php } ?>
But this doesn't work...any suggestions?
Thank you!

true is only to evaluate booleans.
You need to use isset() or !isempty() dependnig on what you are checking for.

Hi Shawn -
thank you for the reply. Could you be so kind and have a look at this example:
__________________________________________
<?php if(isset($_GET['post']) && $blogSettings["customfieldname"] == 'Y') { ?> do stuff <?php } ?>
__________________________________________
How should I write it than?
Thank you!

okoko: Thanks - it works like this:
<?php if (!empty($post->customfieldname)) { ?>
do stuff <?php } ?>
