添加 WooCommerce 结帐复选框字段,根据产品数量启用折扣
Add a WooCommerce checkout checkbox field that enable a discount based on product quantity
根据 Add a checkout checkbox field that enable a percentage fee in Woocommerce 答案代码,我有一个自定义复选框,我需要在上面为客户提供折扣。
我正在尝试应用 0.03 美元 x 产品数量的自定义折扣,例如
如果数量为 50,则折扣为 50 x 0.03 美元 = 1.5 美元
现在,它从购物车总计中扣除 0.03 美元。谁能帮我达到要求的结果?
这是我的代码尝试:
// Add a custom checkbox fields after billing fields
add_action( 'woocommerce_after_checkout_billing_form', 'add_custom_checkout_checkbox', 20 );
function add_custom_checkout_checkbox(){
// Add a custom checkbox field
woocommerce_form_field( 'discount30', array(
'type' => 'checkbox',
'label' => __(' Senior'),
'class' => array( 'form-row-wide' ),
), '' );
}
// Remove "(optional)" label on "Installement checkbox" field
add_filter( 'woocommerce_form_field' , 'remove_order_comments_optional_fields_label', 10, 4 );
function remove_order_comments_optional_fields_label( $field, $key, $args, $value ) {
// Only on checkout page for Order notes field
if( 'discount30' === $key && is_checkout() ) {
$optional = ' <span class="optional">(' . esc_html__( 'optional', 'woocommerce' ) .
')</span>';
$field = str_replace( $optional, '', $field );
}
return $field;
}
// jQuery - Ajax script
add_action( 'wp_footer', 'checkout_fee_script' );
function checkout_fee_script() {
// Only on Checkout
if( is_checkout() && ! is_wc_endpoint_url() ) :
if( WC()->session->__isset('enable_fee') )
WC()->session->__unset('enable_fee')
?>
<script type="text/javascript">
jQuery( function($){
if (typeof wc_checkout_params === 'undefined')
return false;
$('form.checkout').on('change', 'input[name=discount30]', function(e){
var fee = $(this).prop('checked') === true ? '1' : '';
$.ajax({
type: 'POST',
url: wc_checkout_params.ajax_url,
data: {
'action': 'enable_fee',
'enable_fee': fee,
},
success: function (result) {
$('body').trigger('update_checkout');
},
});
});
});
</script>
<?php
endif;
}
// Get Ajax request and saving to WC session
add_action( 'wp_ajax_enable_fee', 'get_enable_fee' );
add_action( 'wp_ajax_nopriv_enable_fee', 'get_enable_fee' );
function get_enable_fee() {
if ( isset($_POST['enable_fee']) ) {
WC()->session->set('enable_fee', ($_POST['enable_fee'] ? true : false) );
}
die();
}
// Add a custom 3 Cents Discount
add_action( 'woocommerce_cart_calculate_fees', 'custom_discount', 20, 1 );
function custom_discount( $cart ) {
// Only on checkout
if ( ( is_admin() && ! defined( 'DOING_AJAX' ) ) || ! is_checkout() )
return;
$discount = -0.03;
if( WC()->session->get('enable_fee') )
$cart->add_fee( __( 'Discount', 'woocommerce'), ( $discount ) );
}
要根据购物车中的商品数量确定折扣,您可以使用 WC()->cart->get_cart_contents_count();
然后可以在 woocommerce_cart_calculate_fees
动作挂钩中应用。
所以你得到:
