I am trying to pass variables between pages and i am failing

本文关键字：变量失败之间 | 更新日期: 2023-09-27

我一直试图在页面之间传递一个变量，以便在测验中计算分数，由于某种原因，变量没有按我希望的方式在页面之间传播，如果点击第一个按钮，我希望分数为1，如果点击第二个按钮，则分数为2，到目前为止，我点击哪一个按钮，结果总是0。

第1页-减去一大堆样式：

<?PHP
$Score=0;
if ( isset( $_POST['Submit1'] ) ) { 
    $Score=$Score+1;
}
if ( isset( $_POST['Submit2'] ) ) { 
    $Score=$Score+2;
}
?>
<body>
<center><img src="http://fc06.deviantart.net/fs70/f/2011/002/d/3/purple_blob_pet_by_bunni0222-d36aw4q.png" alt="" align="middle"/></center>
<FORM NAME ="form1" METHOD ="POST" ACTION ="Test1.php">
<INPUT TYPE = "Hidden" Name = "h1" Value = <?PHP echo $Score; ?> >
<center><INPUT TYPE = "Submit" class=myButton Name = "Submit1" VALUE = "1"></center>
<center><INPUT TYPE = "Submit" class=myButton Name = "Submit2" VALUE = "2"></center>
</FORM>

</body>

这是完整的第二页：

<html>
  <head>
    <title>Test</title>
  </head>
  <body>
    <p>
      <?php
        $Score = 0;
        //error_reporting(0);
        $Score = $_POST['h1'];
        echo $Score;

      ?>
    </p>
  </body>
</html>

我会感谢你的帮助，如果这是愚蠢的事情，我道歉，我只是在学习如何写html和php。

我认为问题出在这一行：

<INPUT TYPE = "Hidden" Name = "h1" Value = <?PHP echo $Score; ?> >

至

<INPUT TYPE = "Hidden" Name = "h1" Value = "<?PHP echo $Score; ?>" >

将第一页php代码放在第二页php的顶部。它会起作用的。。

第一页将是

<body>
<center><img src="http://fc06.deviantart.net/fs70/f/2011/002/d/3/purple_blob_pet_by_bunni0222-d36aw4q.png" alt="" align="middle"/></center>
<FORM NAME ="form1" METHOD ="POST" ACTION ="Test1.php">
<INPUT TYPE = "Hidden" Name = "h1" Value = <?PHP echo $Score; ?> >
<center><INPUT TYPE = "Submit" class=myButton Name = "Submit1" VALUE = "1"></center>
<center><INPUT TYPE = "Submit" class=myButton Name = "Submit2" VALUE = "2"></center>
</FORM>
</body>

第二页是

<html>
  <head>
    <title>Test</title>
  </head>
  <body>
    <p>
      <?php
        $Score=0;
if ( isset( $_POST['Submit1'] ) ) { 
    $Score=$Score+1;
}
if ( isset( $_POST['Submit2'] ) ) { 
    $Score=$Score+2;
}
        $Score = $_POST['h1'];
        echo $Score; ?>
    </p>
  </body>
</html>

FirstPage.php应该如下所示。

<body>
    <FORM NAME ="form1" METHOD ="POST" action="SecondPage.php">
        <center><input TYPE = "Submit"  name = "Submit1" VALUE = "1"></center>
        <center><input TYPE = "Submit" name = "Submit1" VALUE = "2"></center>
    </FORM>
</body>

SecondPage.php应该喜欢这个

<body>
    <p>
      <?php
            $Score=0;   
            if ( isset( $_POST['Submit1'] ) ) { 
                $Score=$_POST['Submit1'];   
            }
            echo $Score; 
      ?>
    </p>
</body>
