Move coupon form before payment section in WooCommerce checkout

由 和自甴很熟 提交于 2021-01-27 16:10:31
问题 I would like to move the coupon field at checkout to the woocommerce_review_order_before_payment hook. Having the coupon field at the top of the page negatively affects conversions as users immediately try looking for a coupon code and abandon checkout if they fail to find one. I read online that it's not that simple because the coupon field is also a form. And placing the coupon field anywhere inside the checkout form causes the "Apply Coupon" to submit the order form instead of applying the

Send Angular $http.delete with body

由 不羁岁月 提交于 2021-01-27 14:30:35
问题 In my Angular app, I need to send an $http.delete request this route /projects/:id/activityTypes (note it does not end with an activity type id) passing a body with the following format: [{"id": 2}] This is to allow batch delete operations by sending multiple objects within the array. Testing the route above with Rest Web Service Client I get a 200, OK status so the route is already implemented and working fine, I just need to implement it in my Angular app. Now, I've checked this previous

Page_Load is been fired when WebMethod is called through javascript PageMethods

由 房东的猫 提交于 2021-01-27 14:20:35
问题 I have an aspx page. I've added a ScriptManager to it, and set EnablePageMethods=true , and created a static method marked as [WebMethod] on the server-side. I have always worked with WebMethods, and I've never seen this error before. On javascript, PageMethods is accessible. But when I call my method, the Page_Load method is fired, instead of the WebMethod. I've searched and found other people had this issue as well. But no answers.... Any ideas? HTML: <body> <form id="form1" runat="server">

Reload Masonry Grid after AJAX call

由 痴心易碎 提交于 2021-01-27 14:07:11
问题 I have a Masonry Grid that is working beautifully. It loads perfectly and readjusts. But I am using a plugin that filters results (Search & Filter plugin for Wordpress) and uses AJAX to do that. But after the AJAX call, my masonry grid is no longer working. I know it is due to the fact that I need to reload Masonry after the AJAX call, but I don't exactly know how to do that. Does anyone know how I can do that? Here is my basic HTML structure. <div id="masonry-container> <div id="search

Fastest way to check connection status from browser

由 こ雲淡風輕ζ 提交于 2021-01-27 13:39:32
问题 I'm using web app from which i send data to server very frequently. Option for sending data should be disabled if app has no internet connection. Which is the fastest way to check from browser if you are online? I've used navigator.onLine but it's unreliable because different browsers interpret it differently. My other solution was to put some plain file on server and attemp to reach it every time before sending. Code looked like this: function serverReachable() { var x = new XMLHttpRequest (

问题 I am trying to make an ajax post to the same php page. Ajax: $("#loginForm").submit(function(e) { e.preventDefault(); var postData = $(this).serialize(); $.post("login.php", postData); }); The postData is correct and is in the following format: username=john&password=123123 PHP (same page): if (!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') { echo 'Ajax Request Detected'; } However this if-check always returns false and the echo

Drupal 8 add ajax form element after ajax callback

由 时光怂恿深爱的人放手 提交于 2021-01-27 11:43:37
问题 I am building a drupal form with multiple ajax enabled form elements. I have one select list that does an ajax callback after change. The problem is that it adds a new select list to the page, which is also ajax enabled. This does not seem to work, which seems logical to me because the ajax is actually bundled an added to the page so it is lost in the replacecommand. Is there anyone experienced with this, and does anyone have a solution ? This is my code /** * {@inheritdoc} */ public function
