如何将PHP会话变量提交到隐藏字段中的表单中？ [英] how to submit php session varibles into form in hidden fields?

问题描述

我有一个创建服务器会话变量的脚本。

我需要使用隐藏的表单域将这些变量中的2个插入到一个简单的表单中（在php页面上）。

 <？php 
 session_start（）; 
？>< pre><？php 
 print_r（$ _ SESSION）; 
？> 
  

我用上面的代码创建了一个简单的php页面。我可以很容易地在页面上看到会话变量，就像你从我们从页面复制的代码的这一部分可以看到的那样：

  [login] => andrew8855 
 [pass] => $ P $ BIsPUTQ / e4mJSlaDsRLA48mB20xxIC1 
 [email] => [e-mail] 
 [name_f] => Andrew 
 [name_l] => 
 [street] => 
 [street2] => 
 [city] => 
  

在自定义表单中，我需要从上面获取/打印上面的变量，如下所示：

 < input type =hiddenname =login_emailid =login_emailvalue =[email]/ > 
< input type =hiddenname =login_userid =login_uservalue =[login]/> 
  

所以当提交表单时，会话中存在的变量将以隐藏形式提交领域。

在搜索了几个小时之后，我发现我可以用session_start（）来做到这一点，但是我不清楚如何完成这个。谢谢你的任何建议。

解决方案

会话以session_start（）函数开始。

使用PHP全局变量设置会话变量：$ _SESSION。

如果您没有使用任何自动会话处理框架...如果您使用自己的脚本，那么您必须在使用之前开始会话。您可以尝试

 <？php 
 //开始会话< / p> BR /> 
 session_start（）; 
？> 
  

这是您的脚本的开始位置。之后您可以使用会话变量。

更改您的html模板：

 <输入类型=hiddenname =login_emailid =login_emailvalue =<？php echo $ _SESSION ['email'];？> /> 
< input type =hiddenname =login_userid =login_uservalue =<？php echo $ _SESSION ['login'];？> /> 
  

从PHP 5.4开始，无论short_open_tag（php.ini）设置如何，都会启用内联回显短标签。

如果没有启用，请设置

short_open_tag =在php.ini中打开

之后，重新启动Apache服务器，然后您可以使用

 <？= $ _ SESSION [ '电子邮件'] GT？; 
  

而不是：

 <？php echo $ _SESSION ['email'];？> 
  

您可以尝试 http://www.w3schools.com/php/php_sessions.asp for session.i认为它对你有帮助。

I have a script that creates server session variables.

I need to insert 2 of these variables into a simple form (on a php page) using hidden form fields.

<?php
session_start();
?><pre><?php
print_r($_SESSION);
?> 

I created a simple php page with the code above. I can see the session variables easily on the page, as you can see in this part of the code I copied from the page:

[login] => andrew8855
[pass] => $P$BIsPUTQ/e4mJSlaDsRLA48mB20xxIC1
[email] => [e-mail]
[name_f] => Andrew
[name_l] => 
[street] => 
[street2] => 
[city] =>

In the custom form, I need to get/print the variables from above into the form as so:

<input type="hidden" name="login_email" id="login_email" value="[email]" />
<input type="hidden" name="login_user" id="login_user" value="[login]" />

So when the form is submitted, the variables that exist in the session will be submitted in the hidden form fields.

After searching for hours, I found that I might be able to do this somehow with session_start();....but I'm not clear about how to accomplish this. Thank you for any suggestions.

解决方案

A session is started with the session_start() function.

Session variables are set with the PHP global variable: $_SESSION.

if you are not using any automatic session handling framework ...if you use your own script then you have to must start session before it use.you can try

<?php
// Start the session<br/>
session_start();
?>

which is set beginning of your script.after that you can use session variables.

Change your html template as such :

<input type="hidden" name="login_email" id="login_email" value="<?php echo $_SESSION['email'];?>" />
<input type="hidden" name="login_user" id="login_user" value="<?php echo $_SESSION['login'];?>" />

Since PHP 5.4 the inline echo short tags are always enabled regardless of the short_open_tag (php.ini) setting.

if it's not enable then please Set

short_open_tag=On in php.ini

after that restart your Apache server then you can use

<?=$_SESSION['email']?>

instead of :

<?php echo $_SESSION['email'];?>

you can try http://www.w3schools.com/php/php_sessions.asp for session.i think it's helpful for you.
