我通过URL中的链接将字符串值传递到下一个页面,如下<a href="ApplicationRegister.php?plan=trial">
在ApplicationRegister.php页面中,我得到的值如下$plan = $_GET["plan"];
我会把它放入一个会话变量中,比如$_SESSION['plans'] = $plan;
在这里我得到了价值。但是在if语句之后,即使在使用Session变量之后,我也无法获得该计划的值。
我的完整代码是这样的
$plan = $_GET["plan"];
echo $plan;
$_SESSION['plan'] = $plan;
$plans = $_SESSION['plan'];
echo $_SESSION['plans'];
include('connect.php');
If (isset($_POST['submit']))
{
$CompanyName = $_POST['CompanyName'];
$CompanyEmail = $_POST['CompanyEmail'];
$CompanyContact = $_POST['CompanyContact'];
$CompanyAddress = $_POST['CompanyAddress'];
$StoreName = $_POST['StoreName'];
echo $plans;
$myURL ="$_SERVER[HTTP_HOST]";
$myURL =$StoreName.'.'.$myURL;
if (stripos($myURL, 'www.') !== 0) {
$myURL = 'www.' . $myURL;
}
if (stripos($myURL, 'http://') !== 0) {
$myURL = 'http://' .$myURL;
}
if(stripos($myURL, '.com') !== 0) {
$myURL = $myURL . '.com';
}
echo $plans;
$RegistrationType = $_POST['RegistrationType'];
$Status = "Active";
$sql = "select * from plans where planname = '$plans'";
echo $sql;
mysql_query($sql) or die (mysql_error());
$planID = $row['planid'];
$query1 = "select count(CompanyEmail) from ApplicationRegister where CompanyEmail = '$CompanyEmail'" ;
$result1 = mysql_query($query1) or die ("ERROR: " . mysql_error());
$msg = "";
while ($row = mysql_fetch_array($result1))
{
if($row['count(CompanyEmail)'] > 0)
{
$msg = "<font color='red'> <b>This E-mail id is already registered </b></font> ";
break;
}
}
if($msg == "")
{
$query2 = "select count(URL) from ApplicationRegister where URL = '$myURL' ";
$result2 = mysql_query($query2) or die ("ERROR: " . mysql_error());
$msg = "";
while ($row = mysql_fetch_array($result2))
{
if($row['count(URL)'] > 0)
{
$msg = "<font color='red'> <b>This Stroename is already registered </b></font> ";
break;
}
}
if($msg == "")
{
$sql = "INSERT INTO ApplicationRegister(planid, CompanyName, CompanyEmail, CompanyContact, CompanyAddress, RegistrationType, ApplicationPlan, ApplicationStatus, URL, CreatedDate) VALUES ('$planID', '$CompanyName', '$CompanyEmail', '$CompanyContact', '$CompanyAddress', '$RegistrationType', '$plans', '$Status', '$myURL', NOW() )";
mysql_query($sql) or die(mysql_error());
$id = mysql_insert_id();
$_SESSION['application_id'] = $id;
if($plans == "trail")
{
header("Location: userRegister.php");
exit();
}
else
{
header("Location : PaymentGateway.php");
exit();
}
}
}
}
?>
只有在开始时,它才保持该值,如果我尝试在if (isset($_POST['submit']))
中显示它,它会为计划显示空白值。不知道该怎么办。Plz建议
已编辑即使这样使用后,它也是一样的。我不知道问题出在哪里:(
$plan = $_GET["plan"];
echo $plan;
$_SESSION['plans'] = $plans;
echo $_SESSION['plans'];
// $plan = +$plan;
include('connect.php');
If (isset($_POST['submit']))
{
$CompanyName = $_POST['CompanyName'];
$CompanyEmail = $_POST['CompanyEmail'];
$CompanyContact = $_POST['CompanyContact'];
$CompanyAddress = $_POST['CompanyAddress'];
$StoreName = $_POST['StoreName'];
echo $_SESSION['plans'];
已编辑
在ApplicationRegister.php中,我已经传递了从上一页(如)获得的隐藏值
<input type="hidden" name="plan" value="<?php echo $plan ?>"/>
然后POST方法我已经使用了这个。现在我得到了它的价值。感谢所有
已编辑
if($PlanName == "trail")
{
header("Location: userRegister.php");
exit();
}
else
{
header("Location : PaymentGateway.php");
exit();
}
这是因为您没有在页面顶部调用session_start()
。您需要这样才能使会话在请求之间持久存在(这是会话的要点)
除了没有调用session_start();
之外,这个代码是错误的:
$plan = $_GET["plan"];
echo $plan;
$_SESSION['plan'] = $plan;
$plans = $_SESSION['plan'];
echo $_SESSION['plans'];
应该是:
$plan = $_GET["plan"];
echo $plan;
$_SESSION['plan'] = $plan;
$plans = $_SESSION['plans'];
echo $_SESSION['plans'];
您正在设置$_SESSION['plan']
,然后尝试访问$_SESSION['plans']
。
此外,您是在点击链接还是提交form
?您说您有一个链接,但您的代码试图访问从form
传递的值。
如果您使用的是form
,请不要使用链接。相反,使用select
元素来选择计划,然后将$plan = $_GET["plan"];
更改为$plan = $_POST["plan"];
。
编辑:
对于重定向问题,请尝试以下代码:
echo "<pre>** Plan Name: **'n";
var_dump($PlanName);
echo "</pre>";
if($PlanName == "trail")
{
header("Location: userRegister.php");
exit();
}
else
{
header("Location: PaymentGateway.php");
exit();
}
看看它输出什么。
当有人点击链接时,它将正确设置变量。然而,它不会触及$_POST['submit']
逻辑,因为它不是post,只是get。然后,假设您稍后实际发布到该页面,尝试访问$_GET
中的任何内容都将为null,然后将会话变量重置为null。
你的第一页应该有类似的代码
<form action="ApplicationRegister.php" method="post">
<select name="plan">
<option value="trial">Trial</option>
</select>
<input type="submit"/>
</form>
然后,检查$_POST['plan']
和$_POST['submit']
