[英]Change cart item prices based on custom cart item data in Woocommerce
currently i create a form in product single page so that customer can enter height and width of the product .目前我在产品单页中创建了一个表单,以便客户可以输入产品的高度和宽度。 So the product price vary based on the entered height and width .因此产品价格根据输入的高度和宽度而变化。
I created this form in我在
woocommerce->single-product->add-to-cart->simple.php woocommerce->单一产品->加入购物车->simple.php
Before modification the form is修改前的表格是
<form class="cart" method="post" enctype='multipart/form-data'>
<?php
/**
* @since 2.1.0.
*/
do_action( 'woocommerce_before_add_to_cart_button' );
/**
* @since 3.0.0.
*/
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( $_POST['quantity'] ) : $product->get_min_purchase_quantity(),
) );
/**
* @since 3.0.0.
*/
do_action( 'woocommerce_after_add_to_cart_quantity' );
?>
<button type="submit" name="add-to-cart" value="<?php echo esc_attr( $product->get_id() ); ?>" class="single_add_to_cart_button button alt"><?php echo esc_html( $product->single_add_to_cart_text() ); ?></button>
<?php
/**
* @since 2.1.0.
*/
do_action( 'woocommerce_after_add_to_cart_button' );
?>
</form>
After modification form is修改后的形式是
<form class="cart" method="post" enctype='multipart/form-data'>
<p>width <input type="text" name="new-width" class="new-width"></p>
<p>Height <input type="text" name="new-height" class="new-height"></p>
<?php
/**
* @since 2.1.0.
*/
do_action( 'woocommerce_before_add_to_cart_button' );
/**
* @since 3.0.0.
*/
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( $_POST['quantity'] ) : $product->get_min_purchase_quantity(),
) );
/**
* @since 3.0.0.
*/
do_action( 'woocommerce_after_add_to_cart_quantity' );
?>
<button type="submit" name="add-to-cart" value="<?php echo esc_attr( $product->get_id() ); ?>" class="single_add_to_cart_button button alt"><?php echo esc_html( $product->single_add_to_cart_text() ); ?></button>
<?php
/**
* @since 2.1.0.
*/
do_action( 'woocommerce_after_add_to_cart_button' );
?>
</form>
After this i used the following code and for testing pupose i set value to 30 .在此之后,我使用了以下代码,为了测试目的,我将值设置为 30 。 But it is not working .但它不起作用。 what i missed ?我错过了什么?
add_filter( 'woocommerce_add_cart_item' , 'set_woo_prices');
function set_woo_prices( $woo_data ) {
if(isset( $_POST['new-width'])) { $woo_data['new-width'] =$_POST['new-width']; }
if(isset( $_POST['new-height'])) { $woo_data['new-height'] =$_POST['new-height']; }
if( $_POST['new-width'] !=="" && $_POST['new-height']!=="" ){
$woo_data['data']->set_price( "30" );
}
return $woo_data;
}
Please advice .请指教。 My aim is to change product price based on user entered width and height .我的目标是根据用户输入的 width 和 height 更改产品价格。
You need to use 2 different hooks:您需要使用 2 个不同的钩子:
The code:代码:
add_filter( 'woocommerce_add_cart_item', 'add_custom_cart_item_data', 10, 2 );
function add_custom_cart_item_data( $cart_item_data, $cart_item ) {
if( isset( $_POST['new-width'] ) )
$cart_item_data['new-width'] = $_POST['new-width'];
if(isset( $_POST['new-height'] ) )
$cart_item_data['new-height'] = $_POST['new-height'];
return $cart_item_data;
}
add_action( 'woocommerce_before_calculate_totals', 'set_custom_cart_item_price', 20, 1 );
function set_custom_cart_item_price( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// First loop to check if product 11 is in cart
foreach ( $cart->get_cart() as $cart_item ){
if( isset($cart_item['new-width']) && isset($cart_item['new-height'])
&& ! empty($cart_item['new-width']) && ! empty($cart_item['new-height']) )
$cart_item['data']->set_price( '30' );
}
}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.代码位于活动子主题(或主题)的 function.php 文件或任何插件文件中。
Tested and works测试和工作
