How to output this function to a specific location?

Question

WooCommerce

<?php
/**
 * Product quantity inputs
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/global/quantity-input.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see     https://docs.woocommerce.com/document/template-structure/
 * @package WooCommerce/Templates
 * @version 3.6.0

I want to display this code in the product card, but I don't know how. Can you suggest?

Answer 1

More specifically, what do you mean by output?

Answer 2

It seems to me that you crookedly corrected a piece of code, and use the insertion of the php code into the message, it's clearer.

Answer 3

What you showed is the output template of the quantity input field (input element)
The template can be called with the usual

wc_get_template( 'global/quantity-input.php', $args );

. Actually, that's how it's called. But it needs a certain list of data to work.
The standard call for this template is here.
In general, all you need to do is call the function that calls the template.

do_action( 'woocommerce_before_add_to_cart_quantity' );

    woocommerce_quantity_input( array(
      'min_value'   => apply_filters( 'woocommerce_quantity_input_min', $product->get_min_purchase_quantity(), $product ),
      'max_value'   => apply_filters( 'woocommerce_quantity_input_max', $product->get_max_purchase_quantity(), $product ),
      'input_value' => isset( $_POST['quantity'] ) ? wc_stock_amount( wp_unslash( $_POST['quantity'] ) ) : $product->get_min_purchase_quantity(), // WPCS: CSRF ok, input var ok.
    ) );

    do_action( 'woocommerce_after_add_to_cart_quantity' );

For examples of calling this function and the hooks that frame it, see product type templates,
for example, woocommerce/templates/single-product/add-to-cart/simple.php
