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 $image
doesn’t equal nothing or !=
and if it is in the category id of 7, echo what ever is in the single quotes (which is nothing in this example), otherwise show the <img>
and the value inside “image” which should be the location of the image.
Update: Thanks to Austin from PressedWords for pointing out his trick, from the comment below.
Themes
Add additional meta boxes to Hybrid Theme
At the time of writing this post I have Theme Hybrid as my parent theme, and am using a custom version of Hybrid News that Justin Tadlock offers to the public.
Well I want to tell you how you can add additional custom meta boxes to your child theme’s running the Hybrid Theme.
In your child function.php
file just add the following to create a new post meta box:
/** * Add additional post meta boxes * * by WPCult */ function wpcult_post_meta_boxes($meta_boxes) { $meta_boxes['image'] = array( 'name' => 'image', 'default' => '', 'title' => __('Image:'), 'type' => 'text', 'show_description' => false, 'description' => __('Please use a full size image, larger than 500px (this photo will dynamically re-size itself!'), ); return $meta_boxes; } add_filter('hybrid_post_meta_boxes', 'wpcult_post_meta_boxes');
This will create a custom meta box called Image, and will create a custom field with the id of image.
Additionally you can create this on pages as well by copy/paste and replacing “post_meta_box” with “page_meta_box” every where inside the function.
Tips & Tricks
Sick of images being to large for the content area?
Have you ever uploaded an image that might have been a tad bigger than the width of your content area? I know I have! So here is a little CSS fix to handle these situations.
.post img { max-width: 600px; height: auto; }
That’s it, really simple huh. Just make sure that you change the .post
to the correct body class(which starts with a “.“) or body ID(which starts with a “#“).
Would you like a quick explanation?
The CSS is just telling any image inside the class of .post
to not be more than 600px wide. By the way make sure you change it to fit the dimension of your content width. And the height attribute is set to auto to automatically change the height to match the new width. 🙂

How to: Display RSS feeds from anywhere
Here is a simple way to display any RSS feed in your WordPress blog.
<?php include_once(ABSPATH . WPINC . '/rss.php'); $rss = fetch_rss('http://feeds2.feedburner.com/WPCult'); $items = array_slice($rss->items, 0, 4); if (empty($items)) echo '<li>No items</li>'; else foreach ( $items as $item ) : ?> <a style="font-size: 14px;" href='<?php echo $item['link']; ?>' title='<?php echo $item['title']; ?>'><?php echo $item['title']; ?></a><br /> <p style="font-size: 10px; color: #aaa;"><?php echo date('F, j Y',strtotime($item['pubdate'])); ?></p> <p><?php echo substr($item['summary'],0,strpos($item['summary'], "This is a post from")); ?></p> <?php endforeach; ?>
The first step is to include the WordPress file rss.php
then will apply code after to style the feeds.
Of coarse I forgot to mention, change the RSS feed to the feed you want to pull.

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