我将自定义插件用于WooCommerce运输方法。该插件运行了一个扩展WC_SHIPPT_METHOD的新类,但是问题是在其他功能中计算出"成本"价格。
所以在当前类中有:
public function calculate_shipping( $package=array() ) {
/* $this->add_rate( array(
'id' => $this->id . $this->instance_id,
'label' => $this->title,
'cost' => 0,
) ); */
$rate = array(
'id' => $this->id,
'label' => $this->title,
'cost' => 0,
'taxes' =>false,
//'calc_tax' => 'per_item'
);
// Register the rate
$this->add_rate( $rate );
}
在班级外,在另一个文件中,我有一个功能,该功能计算运费的成本:
//add shipping cost to checkout total
add_action('woocommerce_cart_calculate_fees', 'woo_add_cart_fee');
function woo_add_cart_fee() {
global $woocommerce;
$woocommerce->shipping;
$wc_econt = new WC_Econt_Shipping_Method;
if ( is_checkout() && (bool)$wc_econt->inc_shipping_cost == TRUE ) {
if(!isset($_SESSION)){
session_start();
}
//write_log('session econt customer shipping cost:'.$_SESSION['econt_shipping_cost']);
$extracost = (isset($_SESSION['econt_shipping_cost']) ? $_SESSION['econt_shipping_cost'] : 0 );
if ($extracost != '0') {
WC()->cart->add_fee(__('Econt Express Shipping Method','woocommerce-econt'), $extracost);
}
}
}
如果仅在类功能中将0更改为$ extracode,则不会更新结帐页面上的运输成本:
公共功能calculate_shipping($ package = array()){
/* $this->add_rate( array(
'id' => $this->id . $this->instance_id,
'label' => $this->title,
'cost' => $extracost,
) ); */
$rate = array(
'id' => $this->id,
'label' => $this->title,
'cost' => $extracost,
'taxes' =>false,
//'calc_tax' => 'per_item'
);
// Register the rate
$this->add_rate( $rate );
}
我猜该类在woo_add_cart_fee函数之前运行,这就是为什么它无法获得$ extracost varible的值。
如何解决此问题?
在计算运输成本的功能中,与您的新计算值添加会话变量:
//add shipping cost to checkout total
add_action('woocommerce_cart_calculate_fees', 'woo_add_cart_fee');
function woo_add_cart_fee() {
global $woocommerce;
$woocommerce->shipping;
$wc_econt = new WC_Econt_Shipping_Method;
if ( is_checkout() && (bool)$wc_econt->inc_shipping_cost == TRUE ) {
if(!isset($_SESSION)){
session_start();
}
//write_log('session econt customer shipping cost:'.$_SESSION['econt_shipping_cost']);
$extracost = (isset($_SESSION['econt_shipping_cost']) ? $_SESSION['econt_shipping_cost'] : 0 );
if ($extracost != '0') {
WC()->session->set( 'Econt_Express_Shipping_Method' , $extracost );
}
}
}
然后在计算运输功能上使用WC会话变量来设置以下成本的值:
public function calculate_shipping( $package=array() ) {
/* $this->add_rate( array(
'id' => $this->id . $this->instance_id,
'label' => $this->title,
'cost' => 0,
) ); */
$rate = array(
'id' => $this->id,
'label' => $this->title,
'cost' => WC()->session->get('Econt_Express_Shipping_Method' ),
'taxes' =>false,
//'calc_tax' => 'per_item'
);
// Register the rate
$this->add_rate( $rate );
}
使用下面的JavaScript在结帐时更新您的新运输价值:
$('body').trigger('update_checkout', { update_shipping_method: true });
,如果您在结帐时多次使用上述代码,则可能需要更改计费地址或运输地址或国家/地区的价值,以便能够更新您的价值。这也是我卡住并被迫伪造这些更改的地方,以便WooCommerce可以更新我的运输价值...尽管如此,仍在寻找解决方案...大声笑:)
$("#billing_address_1").trigger("keypress").val(function(i,val){return val + 'a';});
