Showing quantity inputs in WooCommerce loops

Here is a quick snippet showing how you can add quantity inputs to WooCommerce loops for simple products. This used to be only possible through template edits, but is now doable through filters because they are magic.


<?php
/**
* Code should be placed in your theme functions.php file.
*/
add_filter( 'woocommerce_loop_add_to_cart_link', 'quantity_inputs_for_woocommerce_loop_add_to_cart_link', 10, 2 );
function quantity_inputs_for_woocommerce_loop_add_to_cart_link( $html, $product ) {
if ( $product && $product->is_type( 'simple' ) && $product->is_purchasable() && $product->is_in_stock() && ! $product->is_sold_individually() ) {
$html = '<form action="' . esc_url( $product->add_to_cart_url() ) . '" class="cart" method="post" enctype="multipart/form-data">';
$html .= woocommerce_quantity_input( array(), $product, false );
$html .= '<button type="submit" class="button alt">' . esc_html( $product->add_to_cart_text() ) . '</button>';
$html .= '</form>';
}
return $html;
}
