Occasionally, I’ll run into a situation where I need to call a post specifically using the get_post() function. get_post() returns a Post object, with a number of member variables – the one that stores the actual content of the post being post_content. However, if you try just echoing $post->post_content, you’ll get completely unformatted text – which [...]
Get the Current Admin Page Title in a Plugin
Here’s something that comes up for me pretty often: depending on what I’m trying to do, I sometimes need plugin functions to run (or not run) simply based on which admin page the user is visiting. Here’s the WordPress function that will give you the title of the currently loaded admin page:
get_admin_page_title()
So, if you only [...]
How to Hide Certain Custom Fields From the Edit Post Page
Post meta is easily one of the most useful features in WordPress from a developer’s perspective. Adding custom content to a post provides the ability to accomplish countless goals quickly and easily. Sometimes, it makes sense to give the user access to a post meta field – for example, if they need to add a thumbnail [...]
Using a Custom User Table Share Users Between Two WordPress Installs
In one of many, many strokes of genius, the WordPress core developers threw in a bit of code to allow users (ok, other developers) to define a custom user table, and a custom usermeta table for a WordPress install. In it’s simplest form, you can point your Wordpress user table at that of another blog on [...]
How To: Get an Overview of all Action and Filter Hooks
Here’s a very cool little tidbit I found today (strangely enough, I found it in the bbpress codebase, while working on a bbpress plugin..) Wordpress keeps track of which function/filter combinations are registered, along with which action hooks have been called at any point. If you’re having trouble trying to figure out which action hook [...]
New Wordpress Plugin: Default Post Content
Justin over at justintadlock.com made a post a few days ago about how to preset text in the WordPress post editor. It’s a great post, with an interesting filter detailed. In the comments, somebody mentioned that they’d like to be able to preset custom fields as well – something that seems like it shouldn’t work [...]
Saving Wordpress Plugin Options – Admin Panels Done Right
This isn’t a terribly difficult task – it’s incredibly common, and it’s covered multiple places in the codex. So why am I writing about it? A few months ago, I was tasked with customizing a plugin – one that someone else wrote. I need to add some options to it, and their [...]
Creating User Friendly Custom Fields by Modifying the Post Page
Ralph over at ForTheLose.org wrote up a great post on how to use custom fields in wordpress a few days ago, and I thought I’d expand on it with another feature that I use for clients quite often. Custom fields are a great way to store extra post information, and they can really make for [...]
Maybe_Serialize and the Magic of Wordpress
As you may have noticed in a post I made a few days ago about widetizing wordpress plugins, I mentioned that we needed to serialize our variables before we created them as options in wordpress. As it turns out, this isn’t the case – WordPress does it for you when you go to update or [...]
Running Wordpress Admin Functions from a Cron Job
The quick version? Include wp-load.php and wp-admin/admin-functions.php in a file in the plugin directory, and point your cron there. For those of you with nothing important to do, a long winded explanation: I ran into a project a few days ago where the client needed a simple plugin put together – read an xml file, pull [...]
