This meta-data can include bits of information such as: Mood: Happy Currently Reading: Cinderella Listening To: Rock Around the Clock Weather: Hot and humid With some extra coding, it is possible to achieve more complex actions, such as using the metadata to store an expiration date for a post.

Meta-data is handled with key/value pairs. Keys can be used more than once per post. Here is an example of what this information might look like on your post: Currently Reading: Calvin and Hobbes Today's Mood: Jolly and Happy Function Reference Usage Based upon our example above, let's put this into action. On your next post, you can add a new book and mood to your meta-data. Displaying Custom Fields It might look like this in the source code: Wp_enqueue_script() Enqueue a script.

This article assumes that you've read Writing a Plugin, giving an overview (and many details) of how to develop a plugin.

Hooks: Actions and Filters Hooks are provided by WordPress to allow your plugin to 'hook into' the rest of WordPress; that is, to call functions in your plugin at specific times, and thereby set your plugin in motion. You can sometimes accomplish the same goal with either an action or a filter.

Conditional Tags

For example, you might want to display a snippet of text above the series of posts, but only on the main page of your blog. With the is_home() Conditional Tag, that task is made easy. Note the close relation these tags have to WordPress Template Hierarchy. Warning: You can only use conditional query tags after the posts_selection action hook in WordPress (the wp action hook is the first one through which you can use these conditionals).

Templates Languages: English • Español • Italiano • 日本語 • Русский • (Add your language) Templates are the files which control how your WordPress site will be displayed on the Web.


These files draw information from your WordPress MySQL database and generate the HTML code which is sent to the web browser. Through its powerful Theme system, WordPress allows you to define as few or as many Templates as you like all under one Theme. Each of these Template files can be configured for use under specific situations. General Theme Articles. Page Templates. Page Templates Pages are one of WordPress's built-in Post Types. You'll probably want most of your website Pages to look about the same. Sometimes, though, you may need a specific Page, or a group of Pages, to display or behave differently.

This is easily accomplished with Page Templates. Selecting a Page Template Your Theme files should include a default page template (named: page.php). Edit Page Screen: You can assign a custom template for any individual Page by using the Template dropdown in the Edit Page screen (part of the Page Attributes module): Select a Template from the list (e.g., My Custom Page). All Pages Screen: The Quick-Edit and Bulk Edit options on the All Pages screen also have Template dropdowns. Class Reference/WP Query. Languages: English • Italiano • 한국어 • 日本語 • 中文(简体) • Português do Brasil • (Add your language) Description WP_Query is a class defined in wp-includes/class-wp-query.php that deals with the intricacies of a post's (or page's) request to a WordPress blog. The wp-blog-header.php (or the WP class in Version 2.0) gives the $wp_query object information defining the current request, and then $wp_query determines what type of query it's dealing with (possibly a category archive, dated archive, feed, or search), and fetches the requested posts.

It retains a lot of information on the request, which can be pulled at a later date. Interacting with WP_Query Most of the time you can find the information you want without actually dealing with the class internals and global variables. There are two main scenarios you might want to use WP_Query in. The second is during The Loop. Usage Standard Loop. Class Reference/WP Post. Languages: English • Italiano • 日本語 • (Add your language) Role of WP_Post The WP_Post class is used to contain post objects stored by the database and is returned by functions such as get_post.
