WP_Query Arguments: Posts, Pages, and Post Types

In this part of this series on page_id in our example. This 20 is cast to an integer because post_status argument to post__in argument to fetch posts, WordPress will still fetch sticky posts, even if they're not in your list, as you can see in the image above. To omit them, you use the post__in and post_type parameter in this code to just query for pages.

Querying for Post Types

In some of the examples above, I've used the post_type is usually set to any whenever you use the tax_query<code>tax_query argument in your queries.

To give a simple example, here's how you'd query for all of your site's pages:

$args = array(<br>    'post_type' => 'page'<br>);<br>

Custom Post Types

Querying for a custom post type is simple: use the name you gave the post type when registering it, not the title that's used in the admin menus. So let's say you registered your product post types using register_post_type()<code>register_post_type() as follows:

function register_product() {<br><br>    $args = array(<br>        'name' => __( 'Products', 'tutsplus' ),<br>        'singular_name' => __( 'Product', 'tutsplus' )<br>    );<br><br>    register_post_type( 'product', $args );<br>}<br>

The value you use for the post_type<code>post_type argument when querying for products isn't 'Product'<code>'Product' or 'Products'<code>'Products' but 'product'<code>'product':

$args = array(<br>    'post_type' => 'product'<br>);<br>

Attachments

By default, if you try to run a query for attachments, it won't work. That's because WordPress sets the post_status<code>post_status of attachments to inherit<code>inherit and WP_Query<code>WP_Query defaults to 'post_status' => 'publish'<code>'post_status' => 'publish' unless you specify otherwise. So if you want to query for attachments, you must include the post_status<code>post_status argument:

$args = array(<br>    'post_type' => 'attachment',<br>    'post_status' => 'inherit'<br>);<br>

Note that you could also use any<code>any instead of inherit<code>inherit.

Summary

Using WP_Query<code>WP_Query to create custom queries for posts and post types is something I do a lot. As you've seen from the examples here, there are plenty of possibilities:

• Use it to query for top-level pages in your site.
• Use it to query for posts of a specific post type.
• Use it to query for all posts except the ones you specify.
• Use it to query for all the children of the current page.

There are many more possibilities using the arguments covered here, but this should give you a taster.
