If you want to change the number of products dispalyed per page in WooCommerce,
There is no option to do this easily.
You can do this by adding your Code Snippets.
I'm using WPCode to manage code snippets in WordPress. Install and activate it.
Click [Code Snippets] -> [+ Add Snippet] menu from left side menu.
And create new snippet using [Add Your Custom code (New Snippet)].
Set title as your want, select Code Type
to PHP Snippet
.
And Insert below code
// Change the Number of WooCommerce Products Displayed Per Page
add_filter( 'loop_shop_per_page', 'my_loop_shop_per_page', 30 );
function my_loop_shop_per_page( $products ) {
$products = 15;
return $products;
}
Save and Activate your new snippet.
