Tips & Tricks
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.
I talked about Disabling search engine on search pages in a previous post using the meta tag. Today lets go over the web bots Cached copy of your site. If you are working on builder your blog, or have a temporary site up, use the following code:
<meta name="robots" content="noarchive">
This will tell any bot to follow your site, index it, but prevents a cached copy of this page from being available in the search results.
A good idea when trying to get the most out of your blog is usging the meta tag to tell the web bots to search & index your site. But for good SEO you should apply this code in your header.php file of your WordPress blog.
<?php if(is_search()) { ?>
<meta name="robots" content="noindex, nofollow" />
<?php }?>
This will keep your site from getting a hit from bots over duplicate entries. 🙂
Here is a really neat trick! Access your PHP5 while running PHP4.
If you haven’t created a .htaccess file, you may want to check out the WordPress Codex on permalink structure.
Anyway, open any text editing document and paste in this code:
AddType x-mapp-php5 .php
That’ it! Save your text document as .htaccess and your server should parse all .php files as PHP5

No need to call get_post_meta() twice. Save some CPU cycles and echo the $image variable instead for the image src attribute.
