Putting the Loop in Context in wordpress

The Loop is the heart of a theme, which is what controls how your content is displayed. It is the functional connection between the MySQL database data and the HTML that is rendered in the visitor’s browser. Basically, anywhere a post or page is displayed, WordPress is going to use the Loop. This can be a single post or page, a loop of posts, or a sequence of loops with different display options.

Most WordPress themes feature a header, footer, and sidebar element. Figure 5.1 shows how the Loop is placed directly in the middle of these elements, creating your website content area. This section of your website is usually dynamic and will change as you navigate through it.

Figure 5.1 The WordPress Loop

The Loop, by default, is used in your WordPress theme template files. Custom Loops can be created anywhere in your theme template files, as Figure 5.2 shows. Custom Loops are also used in plugins and widgets. Loops can be used anywhere inside of WordPress, but different methods exist for creating custom Loops depending on where they are used, and the potential side effects of each construction will differ.

Figure 5.2 Using multiple Loops

Multiple Loops can be used throughout your theme template files. Custom Loops can be created in your header, sidebars, footer, and main content areas of your website. There is no limit to the number of Loops that can be displayed on your website. Keep in mind that a Loop is effectively a database query to select content and then an iteration over the selection to display it. The default Loop uses context from the visited URL to make that selection, but you can fine-tune and craft a query against the WordPress content database to implement any number of content management processes.

The following section looks at the basic flow control of the Loop and the WordPress template functions provided to customize the way content is displayed while being handled inside of a loop. Having armed you with the basics, you will now explore building custom Loops based on hand-tailoring those query parameters.
