问题描述
我正在创建一个插件,该插件将使用API计算自定义的送货方式。我有一个jQuery脚本,可以根据输入的地址来计算邮政编码。
$("#billing_address_1").suggestions({
serviceUrl: "https://suggestions.dadata.ru/suggestions/api/4_1/rs",token: php_vars.dadata_suggest_token,type: "ADDRESS",count: 5,onSelect: function (suggestion) {
$("#billing_city").val(suggestion.data.city);
$("#billing_state").val(suggestion.data.region);
$("#billing_postcode").val(suggestion.data.postal_code);
if (suggestion.data.settlement_fias_id)
$("#billing_fias_code").val(suggestion.data.settlement_fias_id);
else if (suggestion.data.city_fias_id)
$("#billing_fias_code").val(suggestion.data.city_fias_id);
else
$("#billing_fias_code").val('');
}
});
要存储fias代码,我创建了自定义字段。
add_filter( 'woocommerce_checkout_fields',array( $this,'custom_checkout_fields' ));
add_action( 'woocommerce_checkout_update_order_meta','shipping_apartment_update_order_meta') );
function custom_checkout_fields( $fields ) {
$fields['shipping']['shipping_fias_code'] = array(
'type' => 'text','label' => __('FIAS','woocommerce'),'placeholder' => _x('Код','placeholder','required' => false,'class' => array('form-row-wide'),'clear' => true
);
$fields['billing']['billing_fias_code'] = array(
'type' => 'text','clear' => true
);
return $fields;
}
function shipping_apartment_update_order_meta( $order_id ) {
if ( ! empty( $_POST['shipping_fias_code'] ) ) {
update_post_meta( $order_id,'shipping_fias_code',sanitize_text_field( $_POST['shipping_fias_code'] ) );
}
if ( ! empty( $_POST['billing_fias_code'] ) ) {
update_post_meta( $order_id,'billing_fias_code',sanitize_text_field( $_POST['billing_fias_code'] ) );
}
}
woocommerce的WC_Shipping_Method中的calculate_shipping()方法使用$ package变量计算运输选项,该变量具有一个“目的地”数组字段,其中包含有关运输地址的信息。邮政编码默认情况下传递到此数组中。但是我还需要在$ package中传递我的自定义字段。
据我了解,仅在表单发布后,我创建的字段才会保存通过jQuery脚本添加的信息。但是$ package ['destination']中包含的其他字段在向其中添加信息后会立即保存。
如何将结帐表单中来自自定义字段的数据添加到$package['destination']
变量中?
解决方法
我无法测试(或修改)您的jQuery代码,因此您将不得不自己处理它,也许对其进行一些更改。我已经完全重新审视了您的所有代码(jQuery代码除外),并且一切正常。
因此$package['destination']
将为'fias_code'

}
此代码进入活动子主题(或活动主题)的functions.php文件中。经过测试,可以正常工作。
重要注意事项:
显示并保存fias_code
结帐字段:
我使用的是woocommerce_billing_fields
和woocommerce_shipping_fields
过滤器挂钩,而不是woocommerce_checkout_fields
,因为这样,数据本身就保存为顺序元数据和用户元数据。因此,您不再需要最后一个功能。
订单元密钥以下划线开头,就像所有开票和运输订单元数据一样。
这些字段将显示在“我的帐户”编辑地址上...因此,如果要避免这种情况,则需要为两个相关的挂钩添加条件。
关于我的jQuery代码:
您最好将其复制到外部文件,并以干净的WordPress方式进行注册/排队,将输出限制为仅结帐页面。然后您将删除相关的动作钩子和钩子函数…
关于动作和过滤器挂钩:
您将必须为插件更改所有add_action()
和add_filter()
,例如:
add_filter( 'woocommerce_billing_fields',array($this,'custom_billing_fields') );
add_filter( 'woocommerce_shipping_fields','custom_shipping_fields') );
add_action( 'wp_footer','checkout_send_fias_code_via_ajax_js') );
add_action( 'wp_ajax_fias_code','set_fias_code_to_wc_session') );
add_action( 'wp_ajax_nopriv_fias_code','set_fias_code_to_wc_session') );
add_filter('woocommerce_checkout_get_value','update_fias_code_checkout_fields_values'),2 );
add_filter( 'woocommerce_cart_shipping_packages','add_fias_code_to_destination_shipping_package') );
add_action( 'woocommerce_checkout_order_created','remove_fias_code_custom_wc_session_variable') );
