Use this handy code snippet tool to create custom WordPress queries to display unique content. Read on to learn about the snippet generator and how to use it.
What Is WP_Query and What Can I Do With It?
In the back-end, WordPress runs queries on each page that your site displays. The query it runs depends on the type of page that the user has requested. For instance, if the user is viewing an archive page, the query’s job is to retrieve all posts from that archive.
What if you want to create custom queries to display very specific content that wouldn’t normally be retrieved by WordPress’ standard queries? The WP_Query class allows developers to create custom queries using a number of parameters to define exactly what content you want the query to retrieve and how to output it.
The WP_Query class contains four main elements:
- Arguments for the query.
- The query itself.
- The loop.
- Closing if and while tags.
How Do I Use This WP_Query Snippet Generator Tool?
We’ve put together this WP_Query snippet generator tool to help developers create custom queries for their themes without having to hand-code them. By using this tool, all that’s left to do is set values for the required parameters based on your preference and the tool will generate a theme-specific, custom code snippet for you.
Let’s take a look at each of the fields one by one:
- Theme Slug: Enter your theme’s slug into this field in all lowercase letters, numbers and/or underscores. This value will be used to prefix functions and variables that would otherwise be incompatible with the WordPress core or any installed themes or plugins. Typically, this is the same string as the text domain, with all hyphens replaced by underscores.
- Unique Query Variable Identifier: Enter a descriptive name for your query variable. It will be used to identify the query variable. The query variable identifier should be a unique name in all lowercase letters, numbers and/or underscores.
- Include the Loop: Check this box if you’d like to have the code in the loop be processed on each post. By default, this value is set to false.
- Post ID: Enter the post ID in this field. It should be an integer value.
- Post Slug: Enter the post slug here. It should be in all lowercase letters, numbers, and/or underscores.
- Post Title: Enter the post title value in this text field. It is available with WordPress 4.4 and above.
- Post Parent: The page ID entered in this field will return only the child pages. To return only the top-level entries and excluding all child pages, set this value to 0. This field accepts an int. value.
- Page ID: Enter the page ID in this field. This field accepts an int. value.
- Page Name: Enter the page slug here. It should be in all lowercase letters, numbers, and/or underscores.

- Post to Show Per Page: Enter the number of posts you’d like to have displayed on each page. The value -1 shows all posts.
- Post to Show Per Archive Page: Enter the number of posts to show per page on archive pages only. It overrides posts_per_page and showposts on pages where the functions is_archive() or is_search() return true.
- Offset: Set the number of posts to displace or pass over. It will ignore the paged parameter and break pagination. Note: this parameter is ignored when posts_per_page is set to -1.
- Paged: Enter the number of page. It will show the posts that would normally show up on a given page when the Older Entries link is used.
- Page: Defines the number of page for a static front page. It will show the posts that would normally show up on a given page of a static front page.
- Ignore Post Stickiness: This boolean value determines whether or not to ignore post stickiness. By default, the value is set to false, which means that the sticky posts will be moved to the start of the set. If you set it to true, the sticky posts will not be moved to the start of the set.

How Do I Add the Code Snippets to My Website?
Download the theme’s functions.php file to your desktop via an FTP client. Next, open it up in a text editor and paste the code at the bottom of the file. Hit the Save button and re-upload it to your theme’s directory. Once you’re done, the newly added custom post status will be available for use.
Alternatively, you can add the generated code snippets to your site is by pasting them directly into your current theme’s functions.php file. You can edit it directly by heading over to Appearance > Editor from the admin panel.
