这个问题在这里已经有了答案:

在woocommerce中创建一个新的运输方法3 (1个答案)

封闭 3个月前.

我正试图为WooCommerce创建一个插件，根据产品重量计算运费。我一直在得到这个错误。

警告：WC_Your_Shipping_Method::calculate_Method的声明 声明WC_Your_Shipping_Method::calculate_shipping($package)应该与WC_Shipping_Method::calculate_shipping($package = Array)兼容，在C:\Users\Michelle\Dropbox\MEDIEINSTITUTET\Utveckling mot e-handel\WooCommerce/WC-kurs/wp-content\plugins\frakt/frakt.php第18行。

这是我的整个插件。

<?php

    add_filter( 'woocommerce_shipping_methods', 'add_your_shipping_method' );

?>

I really cant find the error... when I try the code I just see "Mici Shipping" but no price at all, meaning that somehow it does not read the if else statement? Thanks in advance for your help!

Answer 1

你的类WC_Your_Shipping_Method extends WC_Shipping_Method已经有这个方法了.把这个。

public function calculate_shipping( $package ) 

变成这个

public function calculate_shipping( $package = array() )
