如何在其他网页上输出用户输入？

Question

I am setting up a website for ordering pizza and want to be able to output the user's orders on the checkout page. 我正在建立一个网站订购披萨，并希望能够在结帐页面上输出用户的订单。 I need to know which image the user clicked, each image is a different pizza. 我需要知道用户单击的图像，每个图像都是不同的披萨。 The sauce is working perfectly because I can use a form with a submit button, however for the OnlinePizzaOrderingPage.html I cannot use a submit button. 这种调料效果很好，因为我可以使用带有提交按钮的表单，但是对于OnlinePizzaOrderingPage.html，我不能使用提交按钮。 I have included the sql tag below because sql is allowed to be used, however I don't know if it will help in this scenario. 我已在下面添加了sql标记，因为允许使用sql，但是我不知道它在这种情况下是否会有所帮助。 How do I achieve display the type of pizza the user selected on the ShoppingCart.php page? 如何实现显示在ShoppingCart.php页面上用户选择的比萨饼的类型？

I have tried using POST and GET with php and using Javascript. 我试过将POST和GET与php一起使用，并使用Javascript。

Expected results are the pizza type selected by the user through clicking the images on OnlinePizzaOrderingPage.html to be displayed on the ShoppingCart.php page. 预期结果是用户通过单击OnlinePizzaOrderingPage.html上要显示在ShoppingCart.php页面上的图像选择的比萨饼类型。

.html has no native way of retrieving or storing request values (post/get) that can then be passed to a PHP file. .html没有检索或存储可传递到PHP文件的请求值（发布/获取）的本地方法。 You would need to change DetailedSauceandquantitypage.html to to a PHP page, and use a querystring in OnlinePizzaOrderingPage.html to determine which link was clicked on, such as href="DetailedSauceandquantitypage.php?pizza=Supreme" . 您需要将DetailedSauceandquantitypage.html更改为PHP页面，并在OnlinePizzaOrderingPage.html中使用查询字符串来确定单击了哪个链接，例如href="DetailedSauceandquantitypage.php?pizza=Supreme" 。

As was mentioned in a previous question you made, you should seriously consider converting all of your .html files to .php , to avoid having make a ton of changes later, when you want to expand your application files to use php code. 正如您在上一个问题中提到的那样，当您想要扩展应用程序文件以使用php代码时，应认真考虑将所有.html文件转换为.php ，以避免以后进行大量更改。

If you are using Apache web server you could use SSI (server side includes) , but as you are using PHP, it would be a lot simpler and less error prone to convert to PHP instead. 如果您使用的是Apache Web服务器，则可以使用SSI （服务器端包含），但是当您使用PHP时，将其转换为PHP会更加简单，并且出错的可能性也较小。

Example: 例：

I removed some of the javascript for brevity. 为了简洁起见，我删除了一些JavaScript。 I am also not sure how you would like to be able to add on to or checkout the current order, aside from storing it in a database. 除了将其存储在数据库中之外，我还不确定您希望如何添加或签出当前订单。
