Introduction

In Wordpress, custom post types are a powerful feature that allows developers to create custom content types beyond the standard post type. However, when it comes to displaying posts from a specific category, things can get a bit tricky. In this article, we will explore the common issues and solutions for displaying custom post type posts from a specific category in Wordpress.

Understanding Custom Post Types and Categories

Before we dive into the solutions, let's quickly understand how custom post types and categories work in Wordpress.

  • Custom Post Types: Custom post types are a way to create custom content types beyond the standard post type. They allow developers to create custom content types with their own fields, templates, and behaviors.
  • Categories: Categories are a way to group posts together based on their content. They are used to organize and filter posts on a Wordpress site.

Common Issues with Displaying Custom Post Type Posts from a Specific Category

When trying to display custom post type posts from a specific category, you may encounter the following issues:

  • Incorrect Query Parameters: The query parameters used to retrieve posts from a specific category may be incorrect.
  • Missing Category Slug: The category slug may not be set correctly, leading to an empty query result.
  • Category Not Found: The category may not exist or may be deleted, leading to an empty query result.

Solutions for Displaying Custom Post Type Posts from a Specific Category

Solution 1: Using the category_name Parameter

One common way to display custom post type posts from a specific category is by using the category_name parameter in the WP_Query object.

<?php
$the_query = new WP_Query( [
    'post_type'      => 'your_custom_post_type',
    'category_name'  => 'your_category_slug',
] );
?>

In this example, replace your_custom_post_type with the actual name of your custom post type and your_category_slug with the actual slug of the category you want to display posts from.

Solution 2: Using the category__in Parameter

Another way to display custom post type posts from a specific category is by using the category__in parameter in the WP_Query object.

<?php
$the_query = new WP_Query( [
    'post_type'      => 'your_custom_post_type',
    'category__in'   => array( 1, 2, 3 ), // Replace with the actual category IDs
] );
?>

In this example, replace your_custom_post_type with the actual name of your custom post type and 1, 2, 3 with the actual IDs of the categories you want to display posts from.

Solution 3: Using the tax_query Parameter

You can also use the tax_query parameter in the WP_Query object to display custom post type posts from a specific category.

<?php
$the_query = new WP_Query( [
    'post_type'      => 'your_custom_post_type',
    'tax_query'     => array(
        array(
            'taxonomy' => 'category',
            'field'    => 'slug',
            'terms'    => 'your_category_slug',
        ),
    ),
] );
?>

In this example, replace your_custom_post_type with the actual name of your custom post type and your_category_slug with the actual slug of the category you want to display posts from.

Solution 4: Using the get_terms Function

You can also use the get_terms function to retrieve the terms (categories) and then use the WP_Query object to display the posts.

<?php
$terms = get_terms( 'category', array( 'slug' => 'your_category_slug' ) );
if ( ! empty( $terms ) ) {
    $the_query = new WP_Query( [
        'post_type'      => 'your_custom_post_type',
        'tax_query'     => array(
            array(
                'taxonomy' => 'category',
                'field'    => 'slug',
                'terms'    => $terms,
            ),
        ),
    ] );
}
?>

In this example, replace your_custom_post_type with the actual name of your custom post type and your_category_slug with the actual slug of the category you want to display posts from.
