   Hello,

   I am far from experienced with PHP. I know how to cut and paste a little but thats about as far as it goes. I was wondering if somebody could help me out with the following;

   On my blog I use a custom field called "Image" to add an image to the post and show it on top of the blog entry (on single.php). It's a rather big image (560x300). When I add a video to my post I would like that image not to show up. Basically, Im looking for a piece of code that can do the following:

   IF the post contains the tag 'video' DO NOT show image on top of post.

   From what I've read around these forums it seems difficult to do this based on a tag though, so I would also settle for the same code, based on a category instead of a tag.

   IF the post is in category 'video' DO NOT show image on top of post.

   This is what the coding on single.php looks like:

   <div id="content">
   
   	<?php if (have_posts()) : while (have_posts()) : the_post(); ?>
   
           <div class="post" id="post-<?php the_ID(); ?>">
   
   	<h2 class="title"><?php the_title(); ?></h2>
   	<div id="stats" class="clearfloat"><span class="left"> <!-- <?php _e('Geschreven door','arthemia');?> <?php the_author_posts_link(); ?> <?php _e('op','arthemia');?> --> <?php the_time(get_option('date_format')); ?> – <?php the_time(); ?> – <?php the_tags(' ', ' <b>x</b> '); ?></span><span class="right"><a href="#respond"><?php comments_number(__('0 Reacties','arthemia'), __('1 Reactie','arthemia'), __('% Reacties','arthemia') );?></a></span></div>
   
   	<div class="entry clear float">
   
   	<?php $values = get_post_custom_values("Image");
   	if (isset($values[0])) { ?>
   	<p><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><img src="<?php echo bloginfo('template_url'); ?>/scripts/timthumb.php?src=/<?php
   $values = get_post_custom_values("Image"); echo $values[0]; ?>&w=564&h=300&zc=1&q=100"
   alt="<?php the_title(); ?>" class="left" width="564px" height="300px"  /></a></p>
   
   <?php } ?>

   Any help would be much appreciated!

   using the conditional tags in_categeory() or has_tag() might work;
   http://codex.wordpress.org/Function_Reference/in_category
   http://codex.wordpress.org/Function_Reference/has_tag

   example (untested):

   <?php if( !has_tag('video') ) : ?>
   <?php $values = get_post_custom_values("Image");
   	if (isset($values[0])) { ?>
   	<p><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><img src="<?php echo bloginfo('template_url'); ?>/scripts/timthumb.php?src=/<?php
   $values = get_post_custom_values("Image"); echo $values[0]; ?>&w=564&h=300&zc=1&q=100"
   alt="<?php the_title(); ?>" class="left" width="564px" height="300px"  /></a></p>
   <?php } ?>
   <?php endif; ?>

   why don't you simply remove the custom field "Image" from all posts with a video?

   Hey alchymyth, thanks for your reply.

   Like I stated in my first post, I barely know anything about PHP. However, looking at your piece of code, it seems to me that it will show the "Image" when a post contains a 'video' tag. What I want it to do is not show the "Image" when it has the 'video' tag. Again, I might be wrong because I don't know a whole lot about PHP. Im gonna try it out anyway.

   The reason I must use the "Image" custom field is because it not only adds an image on top of my blog post but also as a thumbnail on the homepage.

   if( !has_tag('video') )

   the exclamation mark ! is a php logic negation operator - the above reads "if it not has the tag 'video' - show the image"
