Question

如何将从数据库中检索到的动态详细信息（例如购物车表中的详细信息）从一个页面传递到另一个页面，以便您可以使用mail（）函数通过电子邮件发送它们？我尝试了很多方法“$ message”但没有效果。我是PHP的新手，并没有太多的经验。任何帮助将不胜感激，谢谢。

请说明到目前为止您所尝试的内容您想要将数据从一个页面发送到另一个页面，请尝试在html中使用表单标记并将method属性设置为post和action属性到您要发送数据的位置。
html代码看起来像这样


<form action="post" action="getdata.php">  <input id="val" type="text" value="" name="cart" style="display:none;">  <button type="submit" >hit me</button> </form>

您可以使用javascript

设置输入值


    document.getElementById("val").value="YourValue";

getdata.php看起来像这样


> if ($_SERVER["REQUEST_METHOD"] == "POST"){ 
> $cartval=$_POST['cart'];
> echo $cartval; }

确保在执行用户输入之前验证数据并检查任何隐藏代码
