post_title: Change number of related products displayed

tags: code-snippet

Add code to your child theme's functions.php file or via a plugin that allows custom functions to be added, such as the [Code snippets](https://wordpress.org/plugins/code-snippets/) plugin. Avoid adding custom code directly to your parent theme's `functions.php` file as this will be wiped entirely when you update the theme.
|
|
|
|
Please note that it does not work for all themes because of the way they're coded.
|
|
|
|
```php
|
|
if ( ! function_exists( 'YOUR_PREFIX_related_products_args' ) ) {
|
|
/**
|
|
* Change number of related products output.
|
|
*
|
|
* @param array $args The related products args.
|
|
* @return array The modified related products args.
|
|
*/
|
|
function YOUR_PREFIX_related_products_args( $args ) {
|
|
if ( ! is_array( $args ) ) {
|
|
$args = array();
|
|
}
|
|
|
|
$args['posts_per_page'] = 4; // 4 related products.
|
|
$args['columns'] = 2; // Arranged in 2 columns.
|
|
|
|
return $args;
|
|
}
|
|
}
|
|
add_filter( 'woocommerce_output_related_products_args', 'YOUR_PREFIX_related_products_args', 20 );
|

```
