Custom Fields Hacks For WordPress

Advertisement

In our previous articles on WordPress hacks, we discussed the incredible flexibility of WordPress, which is one of the biggest reasons for its popularity among bloggers worldwide. Custom fields in particular, which let users create variables and add custom values to them, are one of the reasons for WordPress’ flexibility.

In this article, we’ve compiled a list of 10 useful things that you can do with custom fields in WordPress. Among them are setting expiration time for posts, defining how blog posts are displayed on the front page, displaying your mood or music, embedding custom CSS styles, disabling search engine indexing for individual posts, inserting a “Digg this” button only when you need it and, of course, displaying thumbnails next to your posts

1. Set An Expiration Time For Posts

The problem. Sometimes (for example, if you’re running a contest), you want to be able to publish a post and then automatically stop displaying it after a certain date. This may seem quite hard to do but in fact is not, using the power of custom fields.

The solution. Edit your theme and replace your current WordPress loop with this “hacked” loop:

<?php
if (have_posts()) :
     while (have_posts()) : the_post(); ?>
         $expirationtime = get_post_custom_values('expiration');
         if (is_array($expirationtime)) {
             $expirestring = implode($expirationtime);
         }

         $secondsbetween = strtotime($expirestring)-time();
         if ( $secondsbetween > 0 ) {
             // For example...
             the_title();
             the_excerpt();
         }
     endwhile;
endif;
?>

To create a post set to expire at a certain date and time, just create a custom field. Specify expiration as a key and your date and time as a value (with the format mm/dd/yyyy 00:00:00). The post will not show up after the time on that stamp.

Code explanation. This code is simply a custom WordPress loop that automatically looks to see if a custom field called expiration is present. If one is, its value is compared to the current date and time.

If the current date and time is equal to or earlier than the value of the custom expiration field, then the post is not displayed.

Note that this code does not remove or unpublish your post, but just prevents it from being displayed in the loop.

2. Define How Blog Posts Are Displayed On The Home Page

Screenshot

The problem. I’ve always wondered why 95% of bloggers displays all of their posts the same way on their home page. Sure, WordPress has no built-in option to let you define how a post is displayed. But wait: with custom fields, we can do it easily.

The solution. The following hack lets you define how a post is displayed on your home page. Two values are possible:

  • Full post
  • Post excerpt only

Once more, we’ll use a custom WordPress loop. Find the loop in your index.php file and replace it with the following code:

<?php if (have_posts()) :
    while (have_posts()) : the_post();
         $customField = get_post_custom_values("full");
       	 if (isset($customField[0])) {
              //Custom field is set, display a full post
              the_title();
              the_content();
         } else {
              // No custom field set, let's display an excerpt
              the_title();
              the_excerpt();
    endwhile;
endif;
?>

In this code, excerpts are displayed by default. To show full posts on your home page, simply edit the post and create a custom field called full and give it any value.

Code explanation. This code is rather simple. The first thing it does is look for a custom field called full. If this custom field is set, full posts are displayed. Otherwise, only excerpts are shown.

3. Display Your Mood Or The Music You’re Listening To

Screenshot

The problem. About five or six years ago, I was blogging on a platform called LiveJournal. Of course it wasn’t great as WordPress, but it had nice features that WordPress doesn’t have. For example, it allowed users to display their current mood and the music they were listening to while blogging.

Even though I wouldn’t use this feature on my blog, I figure many bloggers would be interested in knowing how to do this in WordPress.

The solution. Open your single.php file (or modify your index.php file), and paste the following code anywhere within the loop:

$customField = get_post_custom_values("mood");
if (isset($customField[0])) {
    echo "Mood: ".$customField[0];
}

Save the file. Now, when you write a new post, just create a custom field called mood, and type in your current mood as the value.

Code explanation. This is a very basic use of custom fields, not all that different from the well-known hack for displaying thumbnails beside your posts’ excerpts on the home page. It looks for a custom field called mood. If the field is found, its value is displayed.

4. Add Meta Descriptions To Your Posts

Screenshot

The problem. WordPress, surprisingly, does not use meta description tags by default.

Sure, for SEO, meta tags are not as important as they used to be. Yet still, they can enhance your blog’s search engine ranking nevertheless.

How about using custom fields to create meta description tags for individual posts?

The solution. Open your header.php file. Paste the following code anywhere within the <head> and </head> tags:

<meta name="description" content="
<?php if ( (is_home()) || (is_front_page()) ) {
    echo ('Your main description goes here');
} elseif(is_category()) {
    echo category_description();
} elseif(is_tag()) {
    echo '-tag archive page for this blog' . single_tag_title();
} elseif(is_month()) {
    echo 'archive page for this blog' . the_time('F, Y');
} else {
    echo get_post_meta($post->ID, "Metadescription", true);
}?>">

Code explanation. To generate meta descriptions, this hack makes extensive use of WordPress conditional tags to determine which page the user is on.

For category pages, tag pages, archives and the home page, a static meta description is used. Edit lines 3, 7 and 9 to define your own. For posts, the code looks for a custom field called Metadescription and use its value for the meta description.

5. Link To External Resources

Screenshot

The problem. Many bloggers have asked me the following question: “How can I link directly to an external source, rather than creating a post just to tell visitors to visit another website?”

The solution to this problem is to use custom fields. Let’s see how we can do that.

The solution. The first thing to do is open your functions.php file and paste in the following code:

function print_post_title() {
	global $post;
	$thePostID = $post->ID;
	$post_id = get_post($thePostID);
	$title = $post_id->post_title;
	$perm  = get_permalink($post_id);
	$post_keys = array(); $post_val  = array();
	$post_keys = get_post_custom_keys($thePostID);

	if (!empty($post_keys)) {
  	  foreach ($post_keys as $pkey) {
    	    if ($pkey=='url1' || $pkey=='title_url' || $pkey=='url_title') {
      	      $post_val = get_post_custom_values($pkey);
    	    }
  	  }
  	  if (empty($post_val)) {
    	    $link = $perm;
  	  } else {
    	    $link = $post_val[0];
  	  }
	} else {
  	  $link = $perm;
	}
	echo '<h2><a href="'.$link.'" rel="bookmark" title="'.$title.'">'.$title.'</a></h2>';
}

Once that’s done, open your index.php file and replace the standard code for printing titles…

<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></h2>

… with a call to our newly created print_post_title() function:

<?php print_post_title() ?>

Now, whenever you feel like pointing one of your posts’ titles somewhere other than your own blog, just scroll down in your post editor and create or select a custom key called url1 or title_url or url_title and put the external URL in the value box.

Code explanation. This is a nice custom replacement function for the the_title() WordPress function.

Basically, this function does the same thing as the good old the_title() function, but also looks for a custom field. If a custom field called url1 or title_url or url_title is found, then the title link will lead to the external website rather than the blog post. If the custom field isn’t found, the function simply displays a link to the post itself.

6. Embed Custom CSS Styles

Screenshot

The problem. Certain posts sometimes require additional CSS styling. Sure, you can switch WordPress’ editor to HTML mode and add inline styling to your post’s content. But even when inline styling is useful, it isn’t always the cleanest solution.

With custom fields, we can easily create new CSS classes for individual posts and make WordPress automatically add them to the blog’s header.

The solution. First, open your header.php file and insert the following code between the <head> and </head> HTML tags:

<?php if (is_single()) {
    $css = get_post_meta($post->ID, 'css', true);
    if (!empty($css)) { ?>
        <style type="text/css">
        <?php echo $css; ?>
        <style>
    <?php }
} ?>

Now, when you write a post or page that requires custom CSS styling, just create a custom field called css and paste in your custom CSS styling as the value. As simple as that!

Code explanation. First, the code above makes sure we’re on an actual post’s page by using WordPress’ conditional tag is_single(). Then, it looks for a custom field called css. If one is found, its value is displayed between <style> and </style> tags.

Source:

7. Re-Define The <title> Tag

Screenshot

The problem. On blogs, as on every other type of website, content is king. And SEO is very important for achieving your goals with traffic. By default, most WordPress themes don’t have an optimized <title> tag.

Some plug-ins, such as the well-known “All in One SEO Pack,” override this, but you can also do it with a custom field.

The solution. Open your header.php file for editing. Find the <title> tag and replace it with the following code:

<title>

<?php if (is_home () ) {
    bloginfo('name');
} elseif ( is_category() ) {
    single_cat_title(); echo ' - ' ; bloginfo('name');
} elseif (is_single() ) {
    $customField = get_post_custom_values("title");
    if (isset($customField[0])) {
        echo $customField[0];
    } else {
        single_post_title();
    }
} elseif (is_page() ) {
    bloginfo('name'); echo ': '; single_post_title();
} else {
    wp_title('',true);
} ?>
</title>

Then, if you want to define a custom title tag, simply create a custom field called title, and enter your custom title as a value.

Code explanation. With this code, I have used lots of template tags to generate a custom <title> tag for each kind of post: home page, page, category page and individual posts.

If the active post is an individual post, the code looks for a custom field called title. If one is found, its value is displayed as the title. Otherwise, the code uses the standard single_post_title() function to generate the post’s title.

Source:

8. Disable Search Engine Indexing For Individual Posts

Screenshot

The problem. Have you ever wanted to create semi-private posts, accessible to your regular readers but not to search engines? If so, one easy solution is to… you guessed it! Use a custom field.

The solution. First, get the ID of the post that you’d not like to be indexed by search engines. We’ll use a post ID of 17 for this example.

Open your header.php file and paste the following code between the <head> and </head> tags:

<?php $cf = get_post_meta($post->ID, 'noindex', true);
    if (!empty($cf)) {
    echo '<meta name="robots" content="noindex"/>';
}
?>

That’s all. Pretty useful if you want certain info to be inaccessible to search engines!

Code explanation. In this example, we used the get_post_meta() function to retrieve the value of a custom field called noindex. If the custom field is set, then a <meta name=”robots” content=”noindex”/> tag is added.

9. Get Or Print Any Custom Field Value Easily With A Custom Function

Screenshot

The problem. Now that we’ve shown you lot of great things you can do with custom fields, how about an automated function for easily getting custom fields values?

Getting custom field values isn’t hard for developers or those familiar with PHP, but can be such a pain for non-developers. With this hack, getting any custom field value has never been easier.

The solution. Here’s the function. Paste it into your theme’s functions.php file. If your theme doesn’t have this file, create it.

function get_custom_field_value($szKey, $bPrint = false) {
	global $post;
	$szValue = get_post_meta($post->ID, $szKey, true);
	if ( $bPrint == false ) return $szValue; else echo $szValue;
}

Now, to call the function and get your custom field value, use the following code:

<?php if ( function_exists('get_custom_field_value') ){
        get_custom_field_value('featured_image', true);
} ?>

Code explanation. First, we use the PHP function_exists() function to make sure the get_custom_field_value function is defined in our theme. If it is, we use it. The first argument is the custom field name (here, featured_image), and the second lets you echo the value (true) or call it for further PHP use (false).

10. Insert A “Digg This” Button Only When You Need It

Screenshot

The problem. To get traffic from well-known Digg.com, a good idea is to integrate its “Digg this” button into your posts so that readers can contribute to the posts’ success.

But do all of your posts need this button? Definitely not. For example, if you write an announcement telling readers about improvements to your website, submitting the post to Digg serves absolutely no value.

The solution. Custom fields to the rescue once again. Just follow these steps to get started:

  1. Open your single.php file and paste these lines where you want your “Digg this” button to be displayed:
    <?php $cf = get_post_meta($post->ID, 'digg', true);
      if (!emptyempty($cf)) {
      echo 'http://digg.com/tools/diggthis.js" type="text/javascript">'} ?>
  2. Once you’ve saved the single.php file, you can create a custom field called digg and give it any value. If set, a Digg button will appear in the post.

Code explanation. This code is very simple. Upon finding a custom field called digg, the code displays the “Digg this” button. The JavaScript used to display the “Digg this” button is provided by Digg itself.

Bonus: Display Thumbnails Next To Your Posts

Screenshot

The problem Most people knows this trick and have implemented it successfully on their WordPress-powered blogs. But I figure some people still may not know how to display nice thumbnails right next to the posts on their home page.

To view examples of this well-known trick, visit my blogs WpRecipes and Cats Who Code.

The solution.

  1. Start by creating a default image in Photoshop or Gimp. The size in my example is 200×200 pixels but is of course up to you. Name the image default.gif.
  2. Upload your default.gif image to the image directory in your theme.
  3. Open the index.php file and paste in the following code where you’d like the thumbnails to be displayed:
    <?php $postimageurl = get_post_meta($post->ID, 'post-img', true);
    if ($postimageurl) {
    ?>
          <a href="<?php the_permalink(); ?>" rel="bookmark"><img src="<?php echo $postimageurl; ?>" alt="Post Pic" width="200" height="200" /></a>
    <?php } else { ?>
          <a href="<?php the_permalink(); ?>" rel="bookmark"><img src="<?php bloginfo('template_url'); ?>/images/wprecipes.gif" alt="Screenshot" width="200" height="200" /></a>
    <?php } ?>
  4. Save the file.
  5. In each of your posts, create a custom field called post-img. Set its value as the URL of the image you’d like to display as a thumbnail.

Code explanation The code looks for a custom field called post-img. If found, its value is used to display a custom thumbnail.

In case a post-img custom field is not found, the default image is used, so you’ll never have any posts without thumbnails.

    I like wordpress, but i am also a good developer. Any application, program, script etc that needs so much hack is NOT an extensible program. WordPress has too much down sides. Definatly the best blogging tool, but WP is putting its users on a one-way track. Too few built-in extensible options. I hope WP devs will include more customizable options in 3.x versions.

    This article demonstrates why WP is just a blogging platform. Many people try to push it as a bona fide CMS, which it is not. However, a top-notch CMS like Joomla, already has most, if not all, of the items in this list as part of its function. No need for code hacks that may or may not work with the next update like WP.

    Great article, however I would also appreciate how to use custom fields with – more custom TinyMCE editors. I know that there is plugin for it – Custom Field Template, but it has problems when multiple WYSIWYG editors are used together.

    It is very useful, especially if you design a WP template that is more like a CMS and you need more editable fields etc.

    Maybe a topic for another SM article? :)

    I’m still wondering why there seems to be no subscribe option for comments here. It would make our lives a lot easier (and make so much more sense) if you could subscribe to the comments of articles you have commented on. How is a conversation going to be maintained otherwise? Am I going to re-check dozens of articles after I have commented on them months ago? Not likely. Which means that anyone who has asked for help may not get it, or, perhaps worse, may not know when they do get it… Come on SM! Sort it out!

    Since wordpress is well known and extensible, there are also 3rd party apps that use custom fields. For example silex(http://silex-ria.org) can be used as a Flash front end for WordPress using custom fields.

    The ‘noindex’ code doesn’t work as expected. First of all, it contains the same error as the ‘css’ code: if (!emptyempty instead of if(!(empty( . Secondly, the noindex tags also get included in the home page (in my case, the post I want to hide is the topmost on the homepage, that might have something to do with it). This hides your entire blog from Google, that’s a little too rigorous for my liking.

    Get tips! I am pulling my hair out to customize my Page Titles… I have tried and retried everything I know for 6 hours now…

    I am wanting to use a custom field per “Page” and have that field be the “Title.”

    I have attempted to edit the “Re-Define The Tag” code until I can take it no longer… and surprisingly there are no blogs about this – they all deal with Post titles….?

    Any idea how to set a custom field on the page level to rewrite the title?

    cheers!

    In case no one knew this… WORDPRESS absolutely sucks! It is the worst ^%$@#$ blog system ever created! It takes twice as long to setup, it is extremely difficult to customize and update, you CANNOT insert features or modify and it requires all kinds of insane plugins for basic functionality and did I mention it sucks!?? That idiot Matt McGyver, or whatever the F his name is, is an arrogant idiot that should drop dead for inflicting this crap on us!!!

    Hi there. Thanks for this, very useful.

    However, the ‘hack’ I want to use (no 1) doesn’t work. Firstly it seems there aren’t enough php tags, and secondly, when containing php elements in php tags, the code fails to pull the post from the database or recognise the timestamp. I may be doing something wrong, but have you actually tested this one?

    If so, is there some setting the time format must be on to make it work or something? Real shame, cos it would be THE perfect solution I’m looking for…

    Hey there, great post! I’ve been hacking through template tags for a long time trying to get my post title and description correct. I want to include a single tag and a single category within the title tag and description tag of my entry pages but still cannot figure out how to do it… Can anyone here tell me how that could be done? Would I need a custom loop? I was hoping that just putting in And would do it but it hasn’t worked. Here is what I am going for, I’ve already got my post title working, just need the cat and tag pieces.

    Post Title **category the post is in** And **tags the post has associated with it**

    The post-img custom field for thumbnail is great. It actually works with external links BUT it doesn’t work with images already uploaded on my website.
    It will won’t automatically display the thumbnails from the images uploaded in previous posts. So I have to edit all my previous posts which have thumbnails and add the “post-img”? Can you guys make it work with uploaded images also???

    PLEASE ANSWER THIS QUESTION because I have searched on google for hours and no one knew the answer.

    Hi
    Can anyone direct me to find some article about displaying list of pages with at least 3-5 custom fields ? I’m almost for 14 days searching on internet, I have only found the article of author of this post (WP Recipes – Jean-Baptiste Jung) , but there is only one custom field:
    http://www.wprecipes.com/how-to-use-a-custom-blurb-when-listing-pages
    . I asked him for the help to add more fields but instead of answer that he has no time or will to help or that he doesn’t have the time to think or he doesnt know the answer he eliminated my question and without any explanation banned my address (@ Jean …at least You should let somebody else to answer )
    Does anybody knows any article where somebody explains how to display more fields in list of pages?
    I have changed my wp-pages into girl’s portfolios so i need list of girls with the girl’s names(page title), country,province,city,age etc.
    Thanks a lot Daniel

    I know this is an old post, but I’ve recently found it during a search. I just wanted to mention that you forgot to close your ‘else’ statement in Example 2. There should be a closing ‘curly bracket’ before your ‘endwhile’.

    Great list as usual, however in #4 (Add Meta Descriptions To Your Posts) is there any reason why one couldn’t instead use a conditional tag for single posts to utilise the post’s excerpt instead of having to enter a custom field value for each post? This seems like the easiest solution for those of us using the excerpt feature unless there is a problem with this I am overlooking?

    PS: Have just realised this post is over a year old which might explain things.

    Can anyone help me with how to replace a custom field value with an image?

    What i want to achieve is replacing a custom field rating between 1 – 5 with the relevant star image, so that for example if the value is 4 it displays the 4star image in the place.

    Gotten so far as to making the value display, but all the attempts to replace with an image has left me with just a placeholder instead of the image itself, although the source code looks correct.

    Need help!
