More often than not my day consists of WordPress website problems I need to find a solutions for. Much of it I can draw from my own experience, but often I’ll Google for the answers I need. Usually though, the answers aren’t found just in one place – they come from forums, blog comments, tutorials, and Q&A sites combined. Over time I gather tidbits of notes on common subjects, and that’s how blog posts like this one are born.
I posted a lengthy blog post yesterday on my blog (WordPress custom post types on steroids), in which I described how to create and manage custom post types using both PHP code and plugins. While writing that post, and while doing client work this week, I came across some really unique custom post type plugins and tricks. Being a big fan of “roundup” resource posts, I’ll present you with all kinds of custom post type goodies you can use in your WordPress website today.
Issues with Custom Post Types
Know your code…
Custom post types in WordPress are great, they turn it from merely a blogging system into a fully fledged CMS with grown up taxonomy capabilities. The problem with them is, you can’t “just create one” in your wp-admin dashboard (like you can a page, post, tag, category, etc.). Most developers I’ve asked use PHP code to create and maintain their custom post types, but some use plugins.
If you are using code, one really cool thing we’ve run across is this WordPress Custom Post Type Code Generator page.
Your mileage may vary with plugins…
Since there are so many options available for custom post types, your mileage with plugins may vary. In most plugins it’s easy to create a new post type, but it varies for editing or deleting. Most don’t handle any type of “migration” at all (renaming a post type, or moving posts from one post type to another). Some have “export” capabilities, some don’t – some CPT plugins place with others (some don’t). There are also different options for dealing with custom fields and meta boxes.
Getting the content to display…
Whether you get a custom post type created by PHP code or a plugin, once you get some content in it – the problem moves from how to create them to how to display them.
The initial issue is the home or archive page for the custom posts. Then you might want to customize the individual single custom post pages, and you might have to deal with the display of additional custom fields or meta information. Last are the style and layout concerns for the post content.
Fixing Common Custom Post Type Problems
We’re going to run through some common custom post type issues we’ve faced, along with some resources we’ve come across for fixing them.
It would probably be helpful first to explain the “template file hierarchy” for custom post types. We’ll explain more about them as we go.
How Do You Display Custom Post Type Archives?
In WordPress a page with a list of posts is commonly known as an “archive” page. Your blog page with latest posts, category and tag pages, date based post lists – are all “archive” pages. If you have a custom post type created, more than likely you’ll some type of inner page to display them in list view (to get at the single page for each).
When custom post types first appeared in WP, you had to create your own archives page manually, which is when plugins like Simple Custom Post Type Archives and Custom post type archives started coming out.
Then (in WP 3.1) archive support for custom post types came out, as long as the CPT was created with the “has_archive” parameter set.
Here’s the PHP code for that:
Before that functionality existed, WordPress developers started the process of creating an archive by creating a new “Page” in the WordPress dashboard. Let’s say your page is for a new custom post type “products”, the page would likely be called “Products” as well.
Next download “page.php” from your WP theme folder in FTP and “save as” something like “page-products.php”.
Then add this code to the top of the file, save – and re-upload to your theme folder:
Then reload the edit screen in wp-admin for your “Recipes” page and you would switch to your new template page for that custom post type, as in this example:
Last – you need to update “the_loop” in page-products.php to display your new custom post type archive. You can find that code if you need in the WP Beginner post about creating a custom post type archive page.
Even though there’s a new way to do this now (which we’re about to explain), let’s talk about when you would use this “theme page template” method for a custom post type archive page. When you have a client that wants editable text above the CPT archive (that they can edit in wp-admin from the page edit screen), this page template is definitely the way to go.
Now that you know the page template way to do it – let’s look at the theme template hierarchy way. If your CPT has the “has_archive” parameter set to true as we previously showed, the your custom post type can use the normal WordPress theme template hierarchy.
So if your custom post type is “products” – then by default with has_archive set to true your website should show www.website.com/products as an archive of products posts using “archive.php” as the theme template for display.
For a custom page this would be the template structure:
So download archive.php and “save as” archive-products.php, and customize it to your liking, and re-upload. This theme template page will now be used for www.website.com/products only.
How Can You Modify Single Custom Post Type Page Layout?
Just like “single.php” would control layout of normal posts, you can create a new template for custom post type single pages (if you want a different layout). You’ll definitely need to do this if you’re going to display custom fields or meta information associated with your CPT content.
This is the format to use:
So if we wanted to create a single template page for products we could download single.php and “save as” single-products.php. This theme file would then be used for all products pages. However, let’s say we had a products post page with a special layout called “Deal of the Day”. Just like we would edit the page in wp-admin at “Products -> Deal of the Day”, to create a theme template for this page we would name it single-products-deal-of-the-day.php, and it would be used for just that one single custom post.
Having explained both of those methods, now here are some quick and dirty custom post type display solutions with plugins:
First, the Custom post type list shortcode plugin. This little gem will output a list of custom posts wherever you can put a shortcode. You could use it in the content area of any post or page, or even in a widget – a great solution for a client or non-coder that needs to get this done easily.
Second, you might be interested in the Post Types Order plugin, which allows you to quickly and easily order any post types in a drag and drop sortable manner without having to delve into the code of individual theme template pages.
How Do I Assign a Page Template to a Single Custom Post Type Page?
Even though we just showed how to easily create a single custom post theme template file, there are reasons why you might want to choose another route. In WordPress, with a normal static “Page”, you can assign a “page template” in the page attributes of the edit screen like this:
You can’t assign a page template to a normal “post” (because they’re for pages). Using the Custom post template plugin you can create single custom post templates, and select them from page attributes on the edit screen.
You might think – why would I need this plugin if I can create them template pages using the single–.php format for custom posts? The reason is, that’s a great way if your a coder and regularly use FTP. But if you have clients and multiple custom post templates they might need to select – this is clearly the better way (for that scenario).
Making Custom Post Types Display in Normal Archives
The “archives.php” is by default the homepage for most archives (date based). In some themes if there is no tag.php or category.php specific pages, the archives.php file runs tag and category archives as well.
Be default archives.php would show normal “posts” and not custom post (types). You can however, make archives.php include custom post types easily with this code:
How To Make Custom Post Type Taxonomy Template Pages
It’s easy to get very confused with WordPress custom posts types and taxonomy. A taxonomy is an ‘ordered list of things’. A taxonomy can exist without a custom post type. A taxonomy can be associated with one or many post types. Categories and tags, for example, could be associated with both normal posts and a custom post type. You can share a taxonomy among posts (or not). You could have a CPT for both “homes” and “apartments”, and both could share a taxonomy “location”. Or they could instead have their own independent “location” taxonomy.
In a bare WordPress install classic posts have built in taxonomy for both categories and tags. The template hierarchy allows you to create theme template pages for theme like this:
category-.php or category-.php
tag-.php or tag-.php
The theme will use archives.php by default for tag and category display, but if you have a tag.php or category.php it will use those (if available). You can create individual cat or tag pages using the -slug versions if you need to. You can’t use this method to create theme template pages for new custom post type taxonomy you’ve created though.
You need to instead create a “taxonomy.php” file in your theme folder. Much like category.php or tag.php, taxonomy.php will be the default file used for any custom taxonomy item.
Here’s the template hierarchy for taxonomy items in WP:
So our custom “location” taxonomy would be controlled by this page:
If we wanted to change the layout for our headquarters page in Dallas then the page would likely be:
How to Display Multiple Custom Post Types on One Page
There’s a lot of ways to do this, but here’s some code that displays all public custom post types (thanks Pippin!):
How to Add Custom Post Types into WordPress Navigation Menus
You might find after creating a CPT that when you go to Appearance -> Menus you can’t find the content to select. You need to make sure the custom post type has show_in_nav_menus set to true. Also in the top of the screen under “screen options”, make sure your custom post type is checked (so you can see it).
Also, if you need to add your main CPT archive pages into your WP nav menus try using a plugin like Custom Post Type’s Archive in WP Nav Menu.
If you need to add custom post links as children of a custom post type archive in navigation – you might try the Custom post types sub menu plugin.
How to Make RSS Feeds for Custom Post Types?
You don’t have to, they are already built into WordPress.
You can access RSS feeds for custom post types like this:
or taxonomy items like this:
However, just because you can access the RSS feeds at these URL’s doesn’t mean they are added into the header of your theme (like they should be). You can get that done automatically using the Custom Post Type RSS Feeds plugin.
How Do I Make ‘Show Custom Post Types’ on my Homepage?
Maybe, despite the fact that you have a custom post type archive – you want to show that content on your homepage (instead of classic posts).
You could add some code like this to your functions.php file of your theme:
Another solution might be to use the Custom Post Type Selector plugin, which enables a new selection under “Settings -> Post Types”, where you can choose which post types are selected for inclusion in the main loop of your blog. By doing this you could intermingle custom post types with classic posts, or turn them off in favor of custom post types, or even use multiple custom post types – all without custom code or changing/creating theme templates.
How to Migration Content From One Custom Post Type to Another
So you have a client that has a custom post type called “products” and they want to rename it to “goods”. Easier said than done right? If you just rename the custom post type – all the content will be lost (no longer associated with it). You could do some db code magic to fix this, or use the Custom Post Type Switcher plugin to switch the post types. You can do the same thing with Post Type Converter.
Caveat: (currently) can only switch from the post edit screens (one by one), and you have to create a new post type to move them to, then you can delete the old one safely.
If you need to do this in bulk – then try either Conver Post Types, or Post Type Convertr.
How Can I Edit Custom Post Type Permalinks?
Check the advanced section below in resource for an in-depth tutorial on how this works, or choose an easier route like using the Custom Post Type Permalinks plugin. You might also have a look at the Permalinks for Hierarchical Custom Post Types if that situation applies to you.
Sometimes you might not want to edit the permalink, as much as you’d like to remove the slug so the URL’s for custom posts are more in the /%postname%/ format (like www.website.com/%custom_post_type_title%/). The remove slug from custom post type plugin gets it done.
