php session variable html not rendering

[sicklermd]

i have a couple test functions that i set up to make this easier to explain.  function setmsg() does just that, sets a message in a session variable.  fuction viewmsg() is called on the redirected page and displays the message and then unsets the variable.   the message shows up just fine, but when i view the source of the page, the html is not there.  make sense?

 

function setmsg(){
	
	//set message to user to display
	$_SESSION['type'] = "noError";
			
			$_SESSION['userMsg'] = "client status changed";
	
	redirect("second.php");
	exit;
	
}

function viewmsg() {
	
	echo '<div id="'.$_SESSION['type'].'">'.$_SESSION['userMsg'].'</div>';		
		

	
	unset($_SESSION['userMsg']);

	
}

  view the source of the "second.php" page and this is what i get.....

 

<div id="noError"></div>

 

the mesage "Client status was changed" clearly displays just fine.  is this normal?

fixed highlighting

Problem is single quotes vs double quotes. $_SESSION['type'] is echo'd with single quotes and therefore will not interpolate the variable.

Nope. Try again.

I think I misread the post. The redirect is obviously not right, but what html is not showing up? You mean your not seeing the usrMsg in the source? You have already unset the variable so it's not going to be in the source.

The stuff inside the <div> from the "userMsg". The "type" is still working fine.

Yeah, I finally figured out what the op was trying to say. Post was not worded very well. I edited my post as you were posting.

I fixed the highlighting so it should look better. Should show that there's no interpolation happening.

i'm not sure i understand, change my single quotes to double?

 

if i unset the $_session['type'] after echoing it, it has the same issue.  it will be visible on the screen, but gone when you view source.

 

also the redirect is another function, sorry i didn't say that.

When you're pulling up the source for the page, the browser is requesting the page a second time. It's not showing you the original source that it was presenting.

If you just want to browse the markup and don't mind seeing the current state of the DOM (as opposed to the original markup that the server returned) then use your browser's Inspect feature, whatever it may be called.
