会话变量不能被访问到不同的页面

-1

我有三个PHP脚本 1. index.php的不同页面的工作问题（包括HTML格式）

<?php 
session_start(); 

if (isset($_POST['submit'])) { 
$_SESSION['billTo_email'] = $_POST['billTo_email']; 

} 
?> 
<form id = 'form_submit' method="post" action = "NetworkOnline.php"> 
<td><input type="text" name="billTo_email" id="f_name2" /></td> 
<td><input type="submit" name="submit" id="submit" value="Submit"/></td> 
</form> 
?>

NetworkOnline.php

<?php 
    session_start(); 
    $_SESSION['billTo_email'] = $_POST["billTo_email"]; 
    ?> 

    $f_name=$_POST["f_name"]; 
    $l_name=$_POST["l_name"]; 
    $billTo_country=$_POST["billTo_country"]; 
    $billTo_city=$_POST["billTo_city"]; 
    $billTo_state=$_POST["billTo_state"]; 
    $billTo_street1=$_POST["billTo_street1"]; 
    $billTo_pin=$_POST["billTo_pin"]; 
    $billTo_email = $_SESSION["billTo_email"];

response.php

<?php 
session_start(); 
$_SESSION["billTo_email"] = $_POST["billTo_email"]; 
?> 

<form name = "form1" method = "post" action="mail.php" > 
<input type="hidden" name="order" id="order" value="<?php echo $order ?>" > 
<input type="hidden" name="bank" id="bank" value="<?php echo $bank ?>" > 
<input type="hidden" name="amount" id="amount" value="<?php echo $amount ?>" > 
<input type = "test" name= "email" id ="email" value= "<?php echo $billTo_email ?>"> 
<input type="submit" id="submit" value="submit" name="submit"> 
</form>

NetworkOnline.php上的结束标记位置错误。 –

下面尝试，

你关闭标签是错误的地方，

的index.php

<?php 
session_start(); 

if (isset($_POST['submit'])) { 
$_SESSION['billTo_email'] = $_POST['billTo_email']; 
} 
?> 
<form id = 'form_submit' method="post" action = "NetworkOnline.php"> 
<td><input type="text" name="billTo_email" id="f_name2" /></td> 
<td><input type="submit" name="submit" id="submit" value="Submit"/></td> 
</form>

NetworkOnline.php

<?php 
    session_start(); 

    $_SESSION['billTo_email'] = $_POST["billTo_email"]; 
    $f_name=$_POST["f_name"]; 
    $l_name=$_POST["l_name"]; 
    $billTo_country=$_POST["billTo_country"]; 
    $billTo_city=$_POST["billTo_city"]; 
    $billTo_state=$_POST["billTo_state"]; 
    $billTo_street1=$_POST["billTo_street1"]; 
    $billTo_pin=$_POST["billTo_pin"]; 
    $billTo_email = $_SESSION["billTo_email"]; 
    ?>

response.php

<?php 
session_start(); 
$_SESSION["billTo_email"] = $_POST["billTo_email"]; 
?> 

<form name = "form1" method = "post" action="mail.php" > 
<input type="hidden" name="order" id="order" value="<?php echo $order; ?>" > 
<input type="hidden" name="bank" id="bank" value="<?php echo $bank; ?>" > 
<input type="hidden" name="amount" id="amount" value="<?php echo $amount; ?>" > 
<input type = "test" name= "email" id ="email" value= "<?php echo $billTo_email; ?>"> 
<input type="submit" id="submit" value="submit" name="submit"> 
</form>

如我在回答中提到的，不需要检查** if（isset（$ _ POST ['submit']））**。 – SHAZ

@SHAZ投票之前告诉我这段代码的危害.. – jlocker

我没有downvote你的代码。 – SHAZ

UPDATE：

您的index.php

<form id = 'form_submit' method="post" action = "NetworkOnline.php"> 
    <td><input type="text" name="billTo_email" id="f_name2" /></td> 
    <td><input type="submit" name="submit" id="submit" value="Submit"/></td> 
</form>

注：无需检查if (isset($_POST['submit'])) { ... }这里，因为index.php发送数据到NetworkOnline.php。

你NetworkOnline.php：

<?php 
    ob_start(); // turn on output buffering 
    session_start(); 
    if(isset($_POST['billTo_email'])) { // work only if **billTo_email** has some value 
    $_SESSION['billTo_email'] = $_POST["billTo_email"]; 
    } 

    // ?> <-- remove this closing tag 

    $f_name=$_POST["f_name"]; // this line of code shows undefined variable, 
     //because in your index.php there is no any f_name field presnet. 

    // your remaining codes 


?>

** Downvoting的原因** ????? – SHAZ

未定义的索引：f_name – jlocker

我明确提到** if（）**条件上面检查变量具有价值。我把这两行代码，只是为了显示编码器**错位**结束标签。 @jlocker – SHAZ

试试这个，的index.php：

<html> 
<form id = 'form_submit' method="post" action = "NetworkOnline.php"> 
<td><input type="text" name="billTo_email" /></td> 
<td><input type="submit" name="submit" id="submit" value="Submit"/></td> 
</form> 
</html>

NetworkOnline.php：

<?php 
session_start(); 
$_SESSION['billTo_email'] = $_POST["billTo_email"]; 
header('Location: response.php'); 
?>

response.php：

<?php 
session_start(); 
$billTo_email=$_SESSION["billTo_email"] 
?> 
<form name = "form1" method = "post" action="mail.php" > 
<br /> 
<br /> 
<input type = "test" name= "email" value= "<?php echo $billTo_email ?>"> 
<input type="submit" id="submit" value="submit" name="submit"> 
</form>
