问题描述
在 Woocommerce 结帐页面中，我尝试在结帐页面上添加一个复选框并将其称为分期付款".
勾选复选框以添加3%总金额.
例如，如果总金额是100$，它会在总金额之前添加一个额外的部分，并称之为分期付款(3% = $3) 并将该金额添加到总数中.
基于"
<小时>仅在选中复选框时激活的分期付款"百分比费用:
In Woocommerce checkout page, I'am trying to add a check box on checkout page and call it "Installment".
When checkbox is ticked to add 3 percent total amount.
For example, if the total amount is 100$ it will add an extra section before the total amount and call it Installment fee (3% = $3) and add that amount to the total.
Based on "Dynamic shipping fee based on custom radio buttons in Woocommerce", Here it's a light changed version, with a checkbox located after billing fields, that will enable a 3% fee when checkbox is checked:
// 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( 'installment_fee', array(
'type' => 'checkbox',
'label' => __(' Installment 3% fee'),
'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( 'installment_fee' === $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=installment_fee]', 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 dynamic 3% fee
add_action( 'woocommerce_cart_calculate_fees', 'custom_percetage_fee', 20, 1 );
function custom_percetage_fee( $cart ) {
// Only on checkout
if ( ( is_admin() && ! defined( 'DOING_AJAX' ) ) || ! is_checkout() )
return;
$percent = 3;
if( WC()->session->get('enable_fee') )
$cart->add_fee( __( 'Installment fee', 'woocommerce')." ($percent%)", ($cart->get_subtotal() * $percent / 100) );
}
Code goes in function.php file of your active child theme (or active theme). Tested and works.
The field displayed after billing checkout fields:
The Percentage "Installment" fee activated only when checkbox is checked:
