This includes the number of posts to display per page, whether commenting is enabled, and more. Once these defaults are established, WordPress checks to see what the user asked for. This information is used to determine which posts to fetch from the database.

If the user didn't ask for a specific post, category, page, or date, WordPress uses the previously collected default values to determine which posts to prepare for the user. If the user did ask for a specific post, category, page, or date, then WordPress will use that information to specify which post s to fetch from the database. After all this is done, WordPress connects to the database, retrieves the specified information, and stores the results in a variable. The Loop uses this variable's value for display in your templates.

By default, if the visitor did not select a specific post, page, category, or date, WordPress uses index. For the first part of this discussion of The Loop we'll focus only on index. Later on, once you understand how things work, we'll investigate tricks with The Loop in other template files.

The following is a functional index file index. This example demonstrates how little is actually necessary for the functioning of The Loop. The following is a step-by-step look at the default usage of the Loop that comes with the default and classic theme in the standard installation of WordPress v1.

Found at the top of the default index. Internally, this is based on a posts counter, which is compared to the total number of posts in the collection. When the posts collection is exhausted the posts counter matches the total number of posts , the while loop ends and The Loop moves on to whatever instructions it has beyond the while statement, still within the if test. For example, the if might have an else clause with statements to be executed if the posts collection did not contain any data in the first place. Once the post data is made available, the template can start converting it into HTML to send to the visitor.

The following template tags get the current post's title, the time it was posted, and who posted it. This is the meat and potatoes of each pass through The Loop:. The post meta data section is located beneath each post's content in the index. If you're using the comments popup window , this link will open the comments window; otherwise it will jump right to this post's comments.

If the visitor is viewing an index of posts i. The following ends The Loop. After this, the various post-related template tags will not work as expected or if they do, they will use the last post from The Loop. This means, that if you need to use a template tag that works within The Loop , you need to put it in before this point. This section, immediately after the end of The Loop, displays navigation controls to move forward and backward by each web page. If the blog is set to display 10 posts per page, and the conditions used by The Loop collect 25 posts, there will be three pages to navigate: The navigation links will allow the visitor to move forward and backward through the collection of posts.

The navigation controls are included outside The Loop, but inside the if condition, so that they only show up if there are any posts. The navigation functions themselves also check whether or not there is anything to which they will link, based on the current Loop, and only display links if there's something to link. No posts show up if, for example, the visitor requested a specific day for which no posts were made or a search was performed that produced no results.

This ends the conditional test of "if there are posts do this, else if there are no posts, do that". Once the conditional test is finished, the default index. WordPress can use different template files for displaying your blog in different ways. In the default WordPress theme, there are template files for the index view, category view, and archive view, as well as a template for viewing individual posts.

Each of these uses The Loop , but does so with slightly different formatting, as well as different uses of the template tags. For any view which does not have a separate template file, WordPress will use index. If a visitor requests a single post, WordPress will first look for a file named single. If that file exists, it will be used to present the post to the visitor.

If that file does not exist, WordPress will use index. This is called the Template Hierarchy. If you are making your own Theme , it's often helpful to look at the template files from the default Theme as a point of reference. It's also helpful to use your theme's index. Doing so may give you a known and working page from which to begin making changes as you create more template files.

An archive is a collection of historical posts. In the default usage, the posts displayed on your main index are recent chronological postings. When a visitor clicks on one of your archive links, or if they manually request a specific date http: By default, the archive will use index.
