Echo custom fields in any category

Here is a neat trick. Say you want to show a custom field in you post or in a certain categories post. There is a simple code you need to write in order to accomplish this:

<?php $image = get_post_meta($post->ID, "image", $single = true); ?>
<?php if($image != '') : if(in_category(7)) { echo ''; } else { ?>
<img src="<?php echo $image ?>" alt="<?php the_title(); ?>" /></a>

In the example above I am calling the variable $image and telling the server that it equals the value of “image” inside get_post_meta or “custom field” of the current post.

Then we are asking if that variable $image doesn’t equal nothing or != and if it is in the category id of 7, echo what ever is in the single quotes (which is nothing in this example), otherwise show the <img> and the value inside “image” which should be the location of the image.

Update: Thanks to Austin from PressedWords for pointing out his trick, from the comment below.
