我正在尝试为WordPress写一个if条件Woocommerce PHP读取文本行如果对于某个特定单词然后执行条件，则返回false。

以下是我要查找的示例：cart.php 

<?php
/**
 * Cart Page
 *
 * @author      WooThemes
 * @package     WooCommerce/Templates
 * @version     2.3.0
 */

if ( ! defined( 'ABSPATH' ) ) {
    exit; // Exit if accessed directly
}

wc_print_notices();

do_action( 'woocommerce_before_cart' ); ?>

<form id="cart-table" action="<?php echo esc_url(  WC()->cart->get_cart_url() ); ?>" method="post">
<?php do_action( 'woocommerce_before_cart_table' ); ?>
<table class="shop_table cart" cellspacing="0">
    <thead>
        <tr>
            <th class="product-remove">&nbsp;</th>
            <th class="product-thumbnail">&nbsp;</th>
            <th class="product-name"><?php _e('Product', 'yit'); ?></th>
            <th class="product-price"><?php _e('Price', 'yit'); ?></th>
            <th class="product-quantity"><?php _e('Quantity', 'yit'); ?></th>
            <th class="product-subtotal"><?php _e('Total', 'yit'); ?></th>
        </tr>
    </thead>
    <tbody>
        <?php do_action( 'woocommerce_before_cart_contents' ); ?>

        <?php

SEE THE RESULT 请帮忙。什么应该是 if条件的产品属性。<​​/ strong>

2 个答案:

答案 0 :(得分：0)

我相信你正在寻找isset()：

if ( isset($attributes['Color']) ){

或者，如果您正在寻找特定的颜色：

if ( isset($attributes['Color']) && $attributes['Color'] == 'somecolor' ){

答案 1 :(得分：0)

如果您正在寻找特定颜色，那么您也可以使用 - 

global $product;
$color = $product->get_attribute( 'Color' );

然后检查if条件。

修改

如果您在购物车页面上，那么global $product对您没用。您需要循环浏览添加到购物车的产品数组，然后检查属性。

如果以下代码可以帮助您，请参阅

    global $woocommerce;

    $cart = $woocommerce->cart->get_cart();

    foreach ( $cart as $key => $values ) {
        $product = $values['data'];
        $attributes = $product->get_attributes();

        if(isset($attributes['Color'])){ //can use in_array() as well
            //Something 
        }
        else{
            //Another Something
        }
    }

您需要将上面的代码放在一个函数中并挂钩到一个合适的WooCommerce过滤器。
