我们有一个销售电脑零件的网站,这个网站上有一个名为“组装你的电脑”的部分,允许用户选择零件(主板 - cpu - ram等)并支付价格并获得他们的组装产品,一切正常,但它需要一个选项来添加“装配费”到购物车。 仅当用户通过“组装您的PC”向导过程时才应添加此费用。 我正在使用此代码,但它将其添加到所有购物车,我的意思是它不是有条件的。
public function calculate_fees( $fees ){
global $woocommerce;
$cart_subtotal = $woocommerce->cart->subtotal;
$additional_fee = 0; // Additional fee
$additional_fee_text = __('Assembling fee : ', 'dornaweb');
if( $_POST['assembly_fee'] === 'flat_assembly_rate' ){
$additional_fee = intval( dw_option('flat_assembly_rate') ) ?: 0; // flat assembly fee
$additional_fee_text .= __(' ( assembly, no warranty )', 'dornaweb');
} elseif( $_POST['assembly_fee'] === 'percentage_assembly_fee' ) {
$additional_fee = dw_option('percentage_assembly_fee') ? ( ( intval( dw_option('percentage_assembly_fee') ) / 100 ) * $cart_subtotal ) : 0; // percentage assembly fee
$additional_fee_text .= __(' ( assembly + one year warranty )', 'dornaweb');
}
$woocommerce->cart->add_fee( $additional_fee_text, intval( $additional_fee ), 1 );
}
并在constructor
上:
add_action( 'woocommerce_cart_calculate_fees', array( $this, 'calculate_fees' ) );
让我解释一下这个向导(组装你的PC)的更多信息: 我们在本节中有3个步骤,
我也尝试添加费用,而我将产品添加到购物车但是这种方式不起作用,当我去购物车页面时,这样没有额外费用
/* User chooses list of products ( mainboard, ram, ... ) and can choose quantity of each product
and also can choose whether he/she wants to get an assembled computer
or just wants to buy the products individually,
then when he/she hits submit products get added to cart all together
in this step assembling fee should be added and calculated in cart total */
if( !empty( $_POST['action'] ) && $_POST['action'] == 'add' ){
/**
* Add each product to cart based on user choice
*/
foreach( $_POST['products'] as $product_id => $data ) {
WC()->cart->add_to_cart( $product_id, $data['qty'] );
}
/**
* Add additional fees
*/
WC()->cart->add_fee( 'Assembling fee', 10 ); // 10 is an example , the fee differs depending on user choice ( no assemble:0, assemlby+warranty:5% of the cart subtotal, assembly+no warranty: a flat fee eg. 20$ )
WC()->cart->calculate_fees();
/**
* Redirect to cart
*/
wp_safe_redirect( WC()->cart->get_cart_url() );
}
答案 0 :(得分:6)
这对我有用,如果有人有同样的问题: 我在产品添加到购物车时设置了一些会话,当购物车获得付款或清空时,我取消了这些会话。
if( !empty( $_POST['action'] ) && $_POST['action'] == 'add' ){
/**
* Add each product to cart based on user choice
*/
foreach( $_POST['products'] as $product_id => $data ) {
WC()->cart->add_to_cart( $product_id, $data['qty'] );
}
/**
* We set sessions after products added to cart
*/
WC()->session->set( 'MY_SESSION', 'My_value' );
/**
* Redirect to cart
*/
wp_safe_redirect( WC()->cart->get_cart_url() );
}
现在,当客户被重定向到另一个页面(在这种情况下,购物车页面)时,我们可以根据该会话确定他/她的购物车额外费用
function dw_calculate_fees( $cart_object ){
global $woocommerce;
if ( is_admin() && ! defined( 'DOING_AJAX' ) ) return;
if( ! WC()->session->MY_SESSION ) return;
$cart_subtotal = $woocommerce->cart->subtotal;
$additional_fee = null;
if( WC()->session->MY_SESSION === 'example_a' ){
$additional_fee = 1;
} elseif( WC()->session->MY_SESSION === 'example_b' ) {
$additional_fee = 2;
} else{
$additional_fee = 0;
}
if( ! is_null( $additional_fee ) ) {
$woocommerce->cart->add_fee( 'Additional fee ', intval( $additional_fee ), 1 );
}
}
add_action( 'woocommerce_cart_calculate_fees', 'dw_calculate_fees' );
我们需要在购物车付款或清空时取消设置这些会话:
add_action( 'woocommerce_cart_emptied', 'dw_unset_fee_session' );
function dw_unset_fee_session(){
unset( WC()->session->MY_SESSION );
}
这对我有用,如果有什么问题,请与我分享。
