How to Get WordPress Post Data Using Custom Query

How to Get WordPress Post Data Using a WordPress Custom Query with tax_query and meta_query
When you’re building advanced functionality in WordPress, the default queries don’t always give you enough control. That’s where using a WordPress custom query with tax_query and meta_query becomes essential.
These tools let you filter posts by taxonomy terms and custom field values, so you can display exactly the content your project needs. Whether it’s a blog, portfolio, product listing, or something more advanced, mastering custom queries will help.
What is a WordPress Custom Query?
A WordPress custom query is a way to override the default post loop and pull specific content based on your own conditions. With WP_Query, you can apply filters like:
✅ tax_query to filter posts by categories, tags, or custom taxonomies
✅ meta_query to filter posts by custom field (post meta) values
Combining these gives you total flexibility to display filtered content across your site.
Why Use tax_query and meta_query with a WordPress Custom Query?
Here’s why developers love this approach:
✔️ Filter posts by categories, tags, or custom taxonomies
✔️ Show posts based on custom fields like “featured” or “rating”
✔️ Combine multiple filters for advanced queries
✔️ Build dynamic sections like carousels, filtered grids, and widgets
✔️ Essential for projects using custom post types or ACF fields
Example: Get Post Data with a WordPress Custom Query
Let’s say you want to:
✅ Get posts from the “news” category
✅ Only show posts where the custom field “featured” is set to “yes”
Here’s the WordPress custom query for that:
<?php
$args = array(
'post_type' => 'post',
'posts_per_page' => 5,
'tax_query' => array(
array(
'taxonomy' => 'category',
'field' => 'slug',
'terms' => 'news',
),
),
'meta_query' => array(
array(
'key' => 'featured',
'value' => 'yes',
'compare' => '=',
),
),
);
$query = new WP_Query($args);
if ( $query->have_posts() ) :
while ( $query->have_posts() ) : $query->the_post();
echo get_the_title() . ;
echo get_the_excerpt() ;
endwhile;
wp_reset_postdata();
else :
echo 'No posts found.';
endif;
This custom query fetches posts exactly how you want — based on both taxonomy and meta field conditions.
Advanced Example with Multiple Filters
Need to filter by multiple conditions? You can extend your WordPress custom query like this:
<?php
$args = array(
'post_type' => 'post',
'posts_per_page' => 10,
'tax_query' => array(
array(
'taxonomy' => 'category',
'field' => 'slug',
'terms' => 'events',
),
),
'meta_query' => array(
'relation' => 'AND',
array(
'key' => 'highlight',
'value' => 'yes',
'compare' => '=',
),
array(
'key' => 'rating',
'value' => 4,
'compare' => '>=',
),
),
);
$query = new WP_Query($args);
This shows posts that:
✅ Are in the “events” category
✅ Have a custom field highlight set to “yes”
✅ Have a rating custom field value of 4 or higher
When to Use a WordPress Custom Query
Consider using a WordPress custom query when you need:
✔️ Custom post listings for specific categories or taxonomies
✔️ Filtered content based on ACF fields or other custom meta
✔️ Dynamic sections like featured posts, product highlights, or rating-based sorting
✔️ Advanced search filters or AJAX-powered content updates
Best Practices for WordPress Custom Queries

'posts_per_page'to control results and optimize performanceAlways reset post data with
wp_reset_postdata()after the custom loopAvoid overly complex queries on high-traffic pages
Sanitize and validate inputs when building dynamic queries
