Introduction

WordPress Templates fit together like the pieces of a puzzle to generate the web pages on your WordPress site. Some templates (the header and footer template files for example) are used on all the web pages, while others are used only under specific conditions.

Since the introduction of Themes in WordPress v1.5, Templates have become more and more configurable. In order to develop WP themes, a proper understanding of the way WordPress selects template files to display the various pages on your blog is essential. If you seek to customize an existing WordPress theme, this article aims to help you decide which template file needs editing.

Using Conditional Tags

WordPress provides more than one way to match templates to query types. WordPress Theme developers can also use Conditional Tags to control which templates will be used to generate a certain page. Some WordPress Themes may not implement all of the template files described here. Some Themes use conditional tags to load other template files. See the Conditional Tags page and Query Based in Theme Development for more.

The Template File Hierarchy

The General Idea

WordPress uses the Query String mdash; information contained within each link on your web site mdash; to decide which template or set of templates will be used to display the page.

First, WordPress matches every Query String to query types mdash; i.e. it decides what type of page (a search page, a category page, the home page etc.) is being requested.

Templates are then chosen mdash; and web page content is generated mdash; in the order suggested by the WordPress Template hierarchy, depending upon what templates are available in a particular WordPress Theme.

WordPress looks for template files with specific names in the current Theme's directory and uses the first matching template file listed under the appropriate query section below.

With the exception of the basic tt style=font-weight:bold; color:#036index.php/tt template file, Theme developers can choose whether they want to implement a particular template file or not. If WordPress cannot find a template file with a matching name, it skips down to the next file name in the hierarchy. If WordPress cannot find any matching template file, tt style=font-weight:bold; color:#036index.php/tt (the Theme's home page template file) will be used.

Examples

If your blog is at tt style=font-weight:bold; color:#036nowikihttp://example.com/wp//nowiki/tt and a visitor clicks on a link to a category page like tt style=font-weight:bold; color:#036nowikihttp://example.com/wp/category/your-cat//nowiki/tt, WordPress looks for a template file in the current Theme's directory that matches the category's ID. If the category's ID is 4, WordPress looks for a template file named tt style=font-weight:bold; color:#036category-4.php/tt. If it is missing, WordPress next looks for a generic category template file, tt style=font-weight:bold; color:#036category.php/tt. If this file does not exist either, WordPress looks for a generic archive template, tt style=font-weight:bold; color:#036archive.php/tt. If it is missing as well, WordPress falls back on the main Theme template file, tt style=font-weight:bold; color:#036index.php/tt.

If a visitor goes to your home page at tt style=font-weight:bold; color:#036nowikihttp://example.com/wp//nowiki/tt, WordPress first determines whether it has a static front page. If a static front page has been set, then WordPress loads that page according to the page template hierarchy. If a static front page has not been set, then WordPress looks for a template file called tt style=font-weight:bold; color:#036home.php/tt and uses it to generate the requested page. If tt style=font-weight:bold; color:#036home.php/tt is missing, WordPress looks for a file called tt style=font-weight:bold; color:#036index.php/tt in the active theme's directory, and uses that template to generate the page.
