javascript - Ajax Post 值未传递到 php 文件

Question

我在将变量传递到 php 页面时遇到问题。

下面是代码:

var varFirst = 'something'; //string
var varSecond = 'somethingelse'; //string

$.ajax({  
   type: "POST",  
   url: "test.php",  
   data: "first="+ varFirst +"&second="+ varSecond,  
       success: function(){  
          alert('seccesss');

   }
});

PHP:

$first = $_GET['first']; //This is not being passed here
$second = $_GET['second']; //This is not being passed here

$con=mysqli_connect("localhost","root","pass","mydb"); 

if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

mysqli_query($con,"INSERT INTO mytable (id, first, second) VALUES ('', $first, $second)");

mysqli_close($con);


}

我是不是漏掉了什么？实际数据正在保存到数据库，但 $first 和 $second 值没有传递到 php 文件。

Answer 1

您正在使用 POST 类型，请在 POST 中检索它:

$first = $_POST['first'];
$second = $_POST['second'];

或者更改您的 JQuery 调用:

$.ajax({  
   type: "GET",  
   url: "test.php",  
   data: "first="+ varFirst +"&second="+ varSecond,  
       success: function(){  
          alert('seccesss');
   }
});
