[SOLVED] Save variable after changing pages?

[Nexy]

Why Hello There! Just wondering how I would save a variable even after you change pages.

 

I have this:

 

<?php

if($_POST['pmsend'] && $_GET['do'] == "mod")
{
$sql = "SELECT username FROM users WHERE username = '$pmuser'";
$res = mysql_query($sql) OR die(mysql_error());

if(!empty($pmuser) && !empty($subject) && !empty($message) && mysql_num_rows($res) == 1)
{
	$pm_set = "1";

	if($_SESSION['user'])
	{
		mysql_query("INSERT INTO pm_inbox(user, sender, subject, date, message, status) 
				VALUES('$pmuser', '".$_SESSION['user']."', '$subject', '".date('m-j-Y')."', '$message', 'Unread')");
		mysql_query("INSERT INTO pm_draft(user, sender, subject, date, message, status) 
				VALUES('$pmuser', '".$_SESSION['user']."', '$subject', '".date('m-j-Y')."', '$message', 'Unread')");
	}
	else if($_COOKIE['user'])
	{
		mysql_query("INSERT INTO pm_inbox(user, sender, subject, date, message, status) 
				VALUES('$pmuser', '".$_COOKIE['user']."', '$subject', '".date('m-j-Y')."', '$message', 'Unread')");
		mysql_query("INSERT INTO pm_draft(user, sender, subject, date, message, status) 
				VALUES('$pmuser', '".$_COOKIE['user']."', '$subject', '".date('m-j-Y')."', '$message', 'Unread')");
	}
}
else if(empty($pmuser) || empty($subject) || empty($message) || mysql_num_rows($res) == 0) { $pm_set = "2"; }
}

if($pm_set == "1")
{
echo "<div class='create' style='width: 495px; padding: .2em; color: #00FF7F'>
	<img src='images/update.ico' alt='' /> Your Message to " . $_SESSION['suser'] . ' has been sent!
		</div>';
}
else if($pm_set == "2")
{
echo "<div class='create' style='width: 495px; padding: .2em; color: #CD5C5C'>
	<img src='images/remove.ico' alt='' /> Your message has encountered a problem!
		</div>";
}

?>

 

When you click submit on the form, it takes you to index.php?page=PM&pg=send&do=mod. After that it takes you back to index.php?page=PM&pg=send. But, once you change pages, I'm guessing the variable $pm_set doesn't have those values any more.

 

Since it doesn't have those variables, it doesn't echo the what is set under them. I tried using a session, but it still didn't display. My question is; is there any way I can save that variable's value once it changes pages and comes back and it shows the message? I did this, to stop the user from pressing refresh and inserting the same thing more than once.

 

I had <form action='index.php?page=PM&pg=send'>, but your still able to press refresh and insert multiple entries of the same thing. I can't use PHP_SELF because this is an included inside of index.php, so it would take me back to the main page. Any help would be appreciated.

 

Thank You!

Sessions work if you do them correctly.  Do you have session_start() on every page that requires sessions?

Yes, I do. But it didn't work the way I did it. I replaced $pm_set = "1"; with $_SESSION['pm_set'] = "1"; and the other with "2". And it didn't display anything under the echo.

Nvm, I figured it out.
