Sending variable using HTTP_REFERER

main.php
------------------


<?
echo $msg;
?>



<form action="process.php" method="post">
<input type="text" name="name">
<input type="hidden" name="action" value="vua">
<input type="submit" value="submit">
</form>



process.php
----------------------

<?

if($action=="vua")

exit();
}

?>


Hi,

I have created above php files. user will type his/her name in input box and clicking on submit button, process.php will check and send a value (name) in $msg variable and redirect to referer page. Then referer page will show the value of $msg

But this script is not working(

Please help me

 

Why not do everything from one file? Try this:

<?

if ( isset( $_POST['name'] )
{
    echo 'hello' . htmlentities( $_POST['name'] ) . '<br />';
}
?>

<form action="process.php" method="post">
<input type="text" name="name">
<input type="hidden" name="action" value="vua">
<input type="submit" value="submit">
</form>

Hi Brewster, I think you forgot the word 'php' beside the "<?" sign.

i.e.

 

oops, you're right. I must have missed that when copying the original code. Thanks for pointing it out.

Thanks for reply

But I need the process.php with its code as the same.

Please help

 

if($action=="vua")
{
$msg="Hello $name";
header("Location: ".$HTTP_REFERER);
exit();
}

you should read about globals

if($_POST['action']=="vua")
{
$msg="Hello $_POST['name']";
header("Location: ".$_SERVER['HTTP_REFERER']);
exit();
}

 

I have used


if($_POST['action']=="vua")
{
$msg="Hello ".$_POST['name'];
header("Location: ".$_SERVER['HTTP_REFERER']);
exit();
}

Not responsing.

msg.php is not getting the value of $msg

By the by, how process.php will send the value of $msg ?????

 

I need to send a value from process.php to msg.php but i need to use HTTP_REFERER

 

HTTP_REFERER doesn't work with other browsers.

 

What exactly do you want to achieve?

You could use something like this, but it just doesn't make sense why would you want it this way:
In main.php replace this:

<?
echo $msg;
?>

PHP:

with this

<?
if (isset($_GET['message'])) echo $_GET['message']; 
?>

PHP:

process.php should contain this code (i took the code version from coches):

if($_POST['action']=="vua")
{
 $msg="Hello ".$_POST['name'];
 header("Location: ".$_SERVER['HTTP_REFERER']."?message=".$msg);
 exit();
}

PHP:

Didn't check the code for errors and vulnerabilites, but just try it out and explain what exactly you want...

 

if($_POST['action']=="vua")
{
$msg="Hello ".$_POST['name'];
echo $_SERVER['HTTP_REFERER'];
header("Location: ".$_SERVER['HTTP_REFERER']);
exit();
}

PHP:

What do you get?

Peace,

 

it is working

Thanks

 

Sessions would work fine aswell.

 

Yes,

I have write the scripts like below and working very well as my requirement

special thanks and repu added


msg.php
-------------

<?
session_start();
session_register("msg");

echo $msg;
?>



<form action="process.php" method="post">
<input type="text" name="name">
<input type="hidden" name="action" value="vua">
<input type="submit" value="submit">
</form>


process.php
-------------------

<?
session_start();
session_register("msg");

if($_POST['action']=="vua")
{
$msg="Hello ".$_POST['name'];
header("Location: msg.php");
exit();
}

?>

 

Thanks for the nice solution. Hope it will help me solve my problem.

welcome @ srobona

Thanks for repu

 

You can use the global $_SESSION when you use sessions, which i prefer to do.

 

Thanks for the better solution
