Calling custom fields for next/previous posts
Custom fields are definitely very useful and are used on many WordPress installs. Today I’m going to show you how to easily get custom fields values outside the loop.
With that said, I’d like to say I am using this snippet for a new theme I am building.
I want to pull a custom field from the “next” & “previous” post. So I used the following to do so:
<?php $previous_post = get_previous_post(); $next_post = get_next_post(); $image_prev = get_post_meta( $previous_post->ID, 'image', $single = true); $image_next = get_post_meta( $next_post->ID, 'image', $single = true); ?>
Simple. This is how I put it to use:
<?php if ( $image_prev != '' ) : ?> <img src="<?php echo FROSTY_SCRIPTS ?>/thumb.php?src=<?php echo $image_prev; ?>&h=50&w=169&zc=1&q=80" alt="" /> <?php endif; ?>
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.
Tips & Tricks
Disable caching of your site or post
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.
Tips & Tricks
Disable search engine on search pages
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. 🙂
