Question

以下代码检查产品ID 117是否在购物车中。如果是，则显示其他结帐字段。

我正在试图弄清楚如何转换此代码，而不是检查产品ID，它检查变量ID。我有两个产品，每个产品有2个变量。我希望表单字段可见的变量ID是7509和7529.我已经尝试了所有我能想到的东西，并且在选择这些变量时似乎无法填充这些字段。

此代码位于http://wordimpress.com/create-conditional-checkout-fields-woocommerce/

/**
 * Add the field to the checkout
 **/
add_action( 'woocommerce_after_order_notes', 'wordimpress_custom_checkout_field' );

 function wordimpress_custom_checkout_field( $checkout ) {

//Check if Book in Cart (UPDATE WITH YOUR PRODUCT ID)
$book_in_cart = wordimpress_is_conditional_product_in_cart( 117 );

//Book is in cart so show additional fields
if ( $book_in_cart === true ) {
    echo '<div id="my_custom_checkout_field"><h3>' . __( 'Book Customization' ) . '</h3><p style="margin: 0 0 8px;">Would you like an inscription from the author in your book?</p>';

    woocommerce_form_field( 'inscription_checkbox', array(
        'type'  => 'checkbox',
        'class' => array( 'inscription-checkbox form-row-wide' ),
        'label' => __( 'Yes' ),
    ), $checkout->get_value( 'inscription_checkbox' ) );

    woocommerce_form_field( 'inscription_textbox', array(
        'type'  => 'text',
        'class' => array( 'inscription-text form-row-wide' ),
        'label' => __( 'To whom should the inscription be made?' ),
    ), $checkout->get_value( 'inscription_textbox' ) );

    echo '</div>';
}

}

/**
 * Check if Conditional Product is In cart
 *
 * @param $product_id
 *
 * @return bool
 */
function wordimpress_is_conditional_product_in_cart( $product_id ) {
//Check to see if user has product in cart
global $woocommerce;

//flag no book in cart
$book_in_cart = false;

foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
    $_product = $values['data'];

    if ( $_product->id === $product_id ) {
        //book is in cart!
        $book_in_cart = true;

    }
}

return $book_in_cart;

}

我很感激可以给予任何帮助。提前谢谢。

Answer 1

使用in_array应该有效。

如此改变

$book_in_cart = wordimpress_is_conditional_product_in_cart( 117 );

传递带有产品ID的数组。

$book_in_cart = wordimpress_is_conditional_product_in_cart( array(117,113) );

然后改变

if ( $_product->id === $product_id ) {

检查产品ID是否在数组中。

if ( in_array($_product->id, $product_id) ) {

如果购物车中的产品在数组中，则会显示这些更改，然后会显示该额外字段。

Answer 2

所有必需的数据都存储在购物车中，更改

if ( $_product->id === $product_id ) {

到

if ( $_product->variation_id === $product_id ) {

要检查多个variation_id将它们作为数组传递，您之前尝试过的以下内容将无效，因为它向调用函数发送1（true）。

wordimpress_is_conditional_product_in_cart(7509 || 7529) // This is incorrect, see @Howlin's answer for the correct way

Woocommerce变量结帐字段基于变量ID
