我在維護會話中的變量時遇到了問題。我已確認，通過頁面導航會保留相同的會話ID，並且我還使用Print_r($_SESSION)來監視變量。PHP變量被覆蓋爲空
我正在使用四頁。
- 的index.php
- custinfo.php
- custbilling.php
- confirm.php
在第一頁我用一種形式將數據發送到下一個頁面。
<form name="prescreen" action="custinfo.php" method="post">
<label>From DIA</label>
<input name="startlocation" id="fromdia" type="radio" value="From DIA">
<label>To DIA</label>
<input name="startlocation" id="todia" type="radio" value="To DIA">
<label>Choose Location:</label>
City:<input name="city" id="city" type="text" />
<span>or</span><br />
Zipcode:<input name="zipcode" id="zipcode" type="text" />
<h3>When do you need picked up?</h3>
<label>Choose Date:</label>
<input name="date" id="date" type="datetime-local" />
<label>Choose Time:</label>
<input name="time" id="time" type="time" />
<input type="submit" value="Get a Ride Now!" class="textbtn"></input>
</form>
在custinfo.php，然後我在文檔的頭部使用：
<?php
session_start();
$_SESSION['testvar'] = 'THIS IS A TEST';
$startlocation = $_POST["startlocation"];
$city = $_POST["city"];
$zipcode = $_POST["zipcode"];
$date = $_POST["date"];
$time = $_POST["time"];
//Assign variables to the Session
$_SESSION['startlocation'] = $startlocation;
$_SESSION['city'] = $city;
$_SESSION['zipcode'] = $zipcode;
$_SESSION['date'] = $date;
$_SESSION['time'] = $time;
?>
的變量正確讀取並存儲在數組中。然後，我在custinfo.php頁面使用此表：
<form name="customerinfo" action="custbilling.php" method="post">
<label>Contact Name</label>
<input name="contactname" id="contactname" type="text">
<label>Contact Email</label>
<input name="contactemail" id="contactemail" type="text">
<label>Contact Phone</label>
<input name="contactphone" id="contactphone" type="text" />
<?php
if($_SESSION['startlocation'] == "From DIA")
{
echo '<hr />';
echo '<label><b>To Location:</b></label>';
echo 'Address1:<input name="toaddress1" id="toaddress1" type="text" />';
echo 'Address2:<input name="toaddress2" id="toaddress2" type="text" />';
echo 'City:<input name="tocity" id="tocity" type="text" />';
echo 'Zip:<input name="tozip" id="tozip" type="text" />';
echo '<hr />';
}
else
{
echo '<hr />';
echo '<label><b>From Location</b></label>';
echo 'Address1:<input name="fromaddress1" id="fromaddress1" type="text" />';
echo 'Address2:<input name="fromaddress2" id="fromaddress2" type="text" />';
echo 'City:<input name="fromcity" id="fromcity" type="text" />';
echo 'Zip:<input name="fromzip" id="fromzip" type="text" />';
echo '<hr />';
}
?>
<input type="submit" value="Book Your Ride!" class="textbtn"></input>
</form>
在custbilling.php頁我把一切都在拉像這樣的頭：
<?php
session_start();
/*Vars from Customer Info */
$contactname = $_POST['contactname'];
$contactemail = $_POST['contactemail'];
$contactphone = $_POST['contactphone'];
if($_SESSION['startlocation'] == "To DIA")
{
$address1 = $_POST['fromaddress1'];
$address2 = $_POST['fromaddress2'];
$city = $_POST['fromcity'];
$zipcode = $_POST['fromzip'];
}
else
{
$address1 = $_POST['toaddress1'];
$address2 = $_POST['toaddress2'];
$city = $_POST['tocity'];
$zipcode =$_POST['tozip'];
}
//Assign Variables to the Session
$_SESSION['contactname'] = $contactname;
$_SESSION['contactemail'] = $contactemail;
$_SESSION['contactphone'] = $contactphone;
$_SESSION['address1']=$address1;
$_SESSION['address2']=$address2;
$_SESSION['city']= $city;
$_SESSION['zipcode'] = $zipcode;
?>
在這一點上，我顯示這樣的信息：\
<h1><?php echo $_SESSION['testvar']; ?></h1>
<h2>Travel Information</h2>
<h3>Please fill out this form:</h3>
<p>Direction of Travel: <?php echo $_SESSION['startlocation']; ?></p>
<p>LocationTo: <?php echo $_SESSION['city'] , $_SESSION['zipcode']; ?></p>
<p>Date: <?php echo $_SESSION['date']; ?></p>
<p>Time: <?php echo $_SESSION['time']; ?></p>
<p>Customer Name: <?php echo $_SESSION['contactname']; ?></p>
<p>Customer Email: <?php echo $_SESSION['contactemail']; ?></p>
<p>Customer Phone: <?php echo $_SESSION['contactphone']; ?></p>
<p>Address Information: <br />
<span>Address 1:</span><?php echo $_SESSION['address1']; ?><br />
<span>Address 2:</span><?php echo $_SESSION['address2']; ?><br />
<span>City:</span><?php echo $_SESSION['city']; ?><br />
<span>ZipCode:</span><?php echo $_SESSION['zipcode']; ?><br />
</p>
但是，保存在數組中的第一篇文章的startlocation和所有變量現在已被刪除。您還可以看到我用來測試會話正在工作的testvariable，並且我的$_SESSION['testvar']在所有文件上正確顯示。我最初的代碼是這樣設置的，就像$_SESSION['varname] = $_POST['varname'];一樣，但是產生了同樣的問題。所以變量會轉到下一頁，但不會繼續到第三頁。
任何幫助將不勝感激。謝謝。
編輯：這可能是有用的信息：

我不明白當我的一個變量在整個時間內都能存活時，情況如何？或者你說這個問題是與index.php？如果是的話，我假設我需要找出一種方法來強制index.php具有https？ 實際上，目前沒有任何頁面正在https下......我強制索引使用https，並且所有地獄都打破了。 （因爲我沒有配置SSL證書） – ElijahGartin
