Cannot declare function twice

时间：2021-02-28 作者：Carrie

我在代码片段插件中使用了两个挂钩：

1.

    add_filter( \'woocommerce_package_rates\', \'businessbloomer_hide_free_shipping_for_shipping_class\', 10, 2 );
       
    function businessbloomer_hide_free_shipping_for_shipping_class( $rates, $package ) {
      
    
     $shipping_class_target = \'1173\'; // This is Deluxe Tables shipping class ID 
       $in_cart = false;
       foreach ( WC()->cart->get_cart_contents() as $key => $values ) {
          if ( $values[ \'data\' ]->get_shipping_class_id() == $shipping_class_target ) {
             $in_cart = true;
             break;
          } 
       }
       if ( $in_cart ) {
          unset( $rates[\'local_pickup:45\'] ); // This is Local Pick up shipping method with ID 
       }
       return $rates;
    }
add_filter( \'woocommerce_package_rates\', \'businessbloomer_hide_free_shipping_for_shipping_class\', 10, 2 ); function businessbloomer_hide_free_shipping_for_shipping_class( $rates, $package ) { $shipping_class_target = \'1750\'; // This is Stag & Doe shipping class ID $in_cart = false; foreach ( WC()->cart->get_cart_contents() as $key => $values ) { if ( $values[ \'data\' ]->get_shipping_class_id() == $shipping_class_target ) { $in_cart = true; break; } } if ( $in_cart ) { unset( $rates[\'WB_Custom_WooCommerce_Shipping_Method52\'] ); // This is Delivery shipping method with ID } return $rates; } 如果一次只激活一个，它就会工作！但是它说我不能两次声明这个函数，那么如何将这两者结合起来呢？我尝试了这么多的变化，但都没有效果。请帮忙！

我同意Pat的意见：最简单的方法是在两个代码片段中的一个片段中重命名函数，在函数定义和add\\u过滤器行中更改名称。但是，如果您确实想将这两者结合到一个片段中，可以执行以下操作：

function businessbloomer_hide_free_shipping_for_shipping_class( $rates, $package ) {
    $deluxe_tables_shipping_class_target = \'1173\';
    $stag_and_doe_shipping_class_target = \'1750\';

    $hide_local_pickup = false;
    $hide_delivery_shipping = false;

    foreach ( WC()->cart->get_cart_contents() as $key => $values ) {
        $shipping_class_id = $values[ \'data\' ]->get_shipping_class_id();
        if ( $deluxe_tables_shipping_class_target == $shipping_class_id ) {
            $hide_local_pickup = true;
        } elseif ( $stag_and_doe_shipping_class_target == $shipping_class_id ) {
            $hide_delivery_shipping = true;
        }
    }
    if ( $hide_local_pickup ) {
        // This is Local Pick up shipping method with ID
        unset( $rates[\'local_pickup:45\'] );
    }
    if ( $hide_delivery_shipping ) {
        // This is Delivery shipping method with ID
        unset( $rates[\'WB_Custom_WooCommerce_Shipping_Method52\'] );
    }
    return $rates;
}
add_filter( \'woocommerce_package_rates\',
            \'businessbloomer_hide_free_shipping_for_shipping_class\', 10, 2 );
（您还可以将代码更改为在两个== $shipping_class_id 行，但我不知道WooCommerce是否将该ID存储为字符串或数字，因此==更安全。）
