# Change number of related products output
|
||
|
||
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 );
|
||
```
