Session variable

Ice725

PAGE1 User enters his name, clicks submit button.
PAGE2 I display his name and a hyperlink to move to 3rd page.
PAGE3 Here I can no longer display his name from the $_SESSION['name'] variable.

I've looked around at other posts and I dont see anything I'm doing wrong.

Note: Page2 DOES work. It's page3 that doesn't show his name.

Here's my code. (I have <? session_start(); ?> at the top of all my pages!)

PAGE1

Simple text box and submit button. Nothing special

Page2

<?php 
	session_start(); 

$name = $_POST['name'];
$_SESSION['name'] = $name;


?>

PAGE 3

<?php 

session_start(); 

?>

<?
	if (empty($_SESSION['name']))
	{
		echo "You have not logged in...<BR>";
		exit;
	}
	else
	{
		echo "Welcome ".$_SESSION['name']."<BR>";
		echo "<a href = \"delete.php\">Lets delete the session value</a><br>";
        echo "<a href = \"destroy.php\">Lets destroy the session</a><br>";
	}
?>


</body>
</html>

When I try and view PAGE3, I get the "You have not logged in..." message. Again, PAGE2 works, not PAGE3

You might want to check php.ini to see if Sessions are enabled(they are by default), you might want to try to print out the SESSION on pages to test them out etc to see if it is your conditions prob oir is it the session not registering.

I only thing I changed in the php.ini was the save path location. Although I dont know if its important, it now reads

session.save_path = C:\temp

If I look in that directory after I test my pages, I do see a bunch of files in there, and they multiply each time I run my pages.

Could you give me an example on how to check if the session is not registering, or how to make it register?

Thanks

Say I do this:

At the top of page1.

<?
   session_start();
   $_SESSION['myvar'] = "Hello World";

?>

On this same page, I add a hyperlink to another page...

On the 2nd page, I simply add this at the top

   <?

  session_start();
  echo $_SESSION['myvar'];
   ?>

When I click the hyperlink on page 1, should I see "Hello World" on page2??

If so, what do I need to do or fix in order for this to work?

If you see Hello World on the second page, then your good 🙂

Ice725

It doesn't :mad:

I'm using version 4.3.4 and phpinfo() says Session Support is enabled.

hmmm there must be something screwed up because the code works good on my server...
Is this a hosting company? If so, maybe you should check with them.
Or you could try session_register()

Ice725

It's installed locally at my home PC. And I tried using the session_register() function but I got a warning

<?
session_start();
$myvar = "Hello";

session_register('myvar');
?>

Produces the following message:

Unknown(): Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0

I've been stuck on this for days!

Yah Ive gottent hat error, before, its soemthing with PHP.INI, try ti enable register_globals, that helps definitely, so I wouldnt know, but the codeyou did before with the tranfer of Hello World from the first to second page wprls perfect on my server. You might want to try it on an external server to see if its your code or if it was your php prob.

I turned register globals on, was off... But it didn't work. I still cannot get it to echo the session variable on the 2nd page. I did venture into the file where its saving the session files, or cookies? Anyway, when I open up the file in notepad, I see

myvar|s:9:"Hello";

So its writing the variable, but I just cannot get it to read it!
