主要思想是验证客人的邮政编码并根据它显示不同的消息。 我使用此线程设置运输代码:Set shipping postcode early before add to cart in WooCommerce
我构建了一个有效的 AJAX 请求,该请求采用着陆页中输入的值。
jQuery(document).ready(function ($) {
let postcodeField = jQuery("#postcode-field");
let postcodeVal;
postcodeField.on("change", function () {
postcodeVal = postcodeField.val();
});
jQuery("#ph_btn").on("click", function () {
var data = {
action: 'postcode_handler',
postcode: postcodeVal
};
// since 2.8 ajaxurl is always defined in the admin header and points to admin-ajax.php
// If you need it on a public facing page, uncomment the following line:
var ajaxurl = ph_script.ajax_url;
jQuery.ajax({
type: 'POST',
url: ajaxurl,
data: data,
success: function (result) {
// console.log(result);
},
error: function () {
console.log("error");
}
});
})
});
然后将该值传递给一个 PHP 函数,该函数应该将 postcode
值添加到访客 session customer_data
。
function my_AJAX_processing_function(){
// Getting the postcode value
$postcode = intval($_POST['postcode'] );
//Check if the input was a valid integer
if ( $postcode == 0 ) {
echo "Invalid Input";
wp_die();
}
//Important: Early enable customer WC_Session
add_action( 'init', 'wc_session_enabler' );
function wc_session_enabler() {
if ( ! is_admin() && ! WC()->session->has_session() ) {
WC()->session->set_customer_session_cookie( true );
}
}
// Get an array of the current customer data stored in WC session
$customer_data = (array) WC()->session->get('customer');
// Change the billing postcode
$customer_data['postcode'] = $postcode;
// Change the shipping postcode
$customer_data['shipping_postcode'] = $postcode;
// Save the array of customer WC session data
WC()->session->set('customer', $customer_data);
// Sending a response to the AJAX request
echo($postcode);
wp_die();
}
我还构建了一个短代码函数来显示客人的 session customer_data
。
function shortcode_postcode_field(){
// Getting the customer data from the session
$customer_data = (array) WC()->session->get('customer');
// Get the billing postcode
// if ( isset( $customer_data['postcode'] ) )
$postcode = $customer_data['postcode'];
// Showing the customer data for debug reasons
var_dump($customer_data);
return '
<p class="form-row postcode-field on" id="postcode-field_field" data-priority="">
<label for="postcode-field" class="">Code postal
<span class="optional">(facultatif)</span>
</label>
<span class="woocommerce-input-wrapper">
<input type="number" class="input-text" name="postcode" id="postcode-field" placeholder="85000" value="">
</span>
<button id="ph_btn" style="color: black">Vérifier son code postal</button>
<p>Votre code postal est '.$postcode.'</p>
</p>
';
}
add_shortcode( 'postcode-field', 'shortcode_postcode_field' );
问题是获取 AJAX 响应的 PHP 函数似乎没有将 postcode
设置为访客 session customer_data
。我试过直接在短代码中设置 postcode
(使用相同的方法)并且它有效。
你能帮我找出问题所在吗?
我也很难调试 - 我怎么知道 session customer_data
已更改?
谢谢。
编辑:我已将客人的 session 客户数据
发送到 AJAX 响应,我得到了这个:
array(26) { ["id"]=> string(1) "0" ... ["postcode"]=> int(44500) ... }
这意味着数据是在 AJAX 响应后立即存储的。问题似乎是当我重新加载页面并再次尝试获取 guest session customer data
时未存储此数据。
最佳答案
您需要在 WC_Customer
对象上使用可用的 setter 和 getter 方法,例如:
WC()->customer->get_billing_postcode()
或WC()->customer->get_shipping_postcode()
WC()->customer->set_billing_postcode()
或WC()->customer->set_shipping_postcode()
现在您的代码中有一些错误。我已经重新访问了您的所有代码,如下所示:
// Early enable customer WC_Session
add_action( 'init', 'wc_session_enabler' );
function wc_session_enabler() {
if ( ! is_admin() && ! WC()->session->has_session() ) {
WC()->session->set_customer_session_cookie( true );
}
}
// Shortcode
add_shortcode( 'postcode-field', 'shortcode_postcode_field' );
function shortcode_postcode_field(){
return '<p class="form-row postcode-field on" id="postcode-field_field" data-priority="">
<label for="postcode-field" class="">' . __("Postcode", "woocommerce") . '
<span class="optional">(optional)</span>
</label>
<span class="woocommerce-input-wrapper">
<input type="number" class="input-text" name="postcode-input" id="postcode-input" placeholder="85000" value="">
</span>
<button id="postcode-submit" name="postcode-submit" class="button alt">' . __("Check your postcode", "woocommerce") . '</button>
<br><div class="postcode-message" style="display:none"></div>
</p>';
}
// Jquery (Ajax sender)
add_action( 'wp_footer', 'postcode_field_js_script' );
function postcode_field_js_script() {
?>
<script type="text/javascript">
jQuery( function($) {
var postcode = '';
$('#postcode-input').on("input change", function () {
postcode = $(this).val();
});
$("#postcode-submit").on('click', function () {
$.ajax({
type: 'POST',
url: '<?php echo admin_url('/admin-ajax.php'); ?>',
data: {
'action': 'postcode_receiver',
'postcode': postcode
},
success: function (response) {
$('.postcode-message').html(response).show(300);
// console.log(response);
},
error: function (error) {
$('.postcode-message').html(error).show(300);
// console.log(error);
}
});
});
});
</script>
<?php
}
// Php (Ajax receiver) - Check and set the postcode - return message (notice)
add_action('wp_ajax_postcode_receiver', 'postcode_receiver');
add_action('wp_ajax_nopriv_postcode_receiver', 'postcode_receiver' );
function postcode_receiver(){
if( isset($_POST['postcode']) ) {
$postcode = sanitize_text_field($_POST['postcode']);
if ( $postcode > 0 ) {
WC()->customer->set_shipping_postcode($postcode);
WC()->customer->set_billing_postcode($postcode);
$saved_postcode = WC()->customer->get_shipping_postcode();
echo sprintf( '<span style="color:green;">' . __("Your postcode %s has been registered successfully.", "woocommerce") . '</span>', '"' . $saved_postcode . '"' );
} else {
echo '<span style="color:red;">' . __("Check your postcode input please.", "woocommerce") . '</span>';
}
wp_die();
} else {
echo '<span style="color:red;">' . __("A problem has occurred, try later.", "woocommerce") . '</span>';
wp_die();
}
}
代码进入事件子主题(或事件主题)的 functions.php 文件。经过测试并有效。
