session variable problem

Expand Post »

Im trying to use session variables to save the puzzle key, and than open a new file that prints it out, but it gives me
Notice: Undefined index: puzzleName in C:\Apache2.2\htdocs\users\jmdrenning0\wordfind\wordfindkey2.php on line 13

i have no idea what it means, any help please.

wordfind.php

PHP Syntax (Toggle Plain Text)
function printPuzzle(){
	//print puzzle
 
	global $puzzle, $word, $keyPuzzle, $boardData;
	//print puzzle itself
 
	print <<<HERE
	<h1>{$boardData["name"]}</h1>
	$puzzle
	<h3>Word List</h3>
	<u1>
 
HERE;
	//print word list
	foreach ($word as $theWord){
		$theWord = rtrim($theWord);
		print "<li>$theWord</li>\n";
	}
	print "</ul>\n";
	$puzzleName = $boardData["name"];
 
	//print form for requesting answer key
	//save answer key as session variable
 
	$_Session["key"] = $keyPuzzle;
	$_Session["puzzleName"] = $puzzleName;
 
	print <<<HERE
 
	<form action = "wordfindkey2.php"
		  method = "post"
		  id = "keyForm">
 
	<div>
	<input type = "submit"
		   value = "show answer key" />
	</div>
	</form>
 
HERE;
}
function printPuzzle(){
	//print puzzle
	
	global $puzzle, $word, $keyPuzzle, $boardData;
	//print puzzle itself
	
	print <<<HERE
	<h1>{$boardData["name"]}</h1>
	$puzzle
	<h3>Word List</h3>
	<u1>
	
HERE;
	//print word list
	foreach ($word as $theWord){
		$theWord = rtrim($theWord);
		print "<li>$theWord</li>\n";
	}
	print "</ul>\n";
	$puzzleName = $boardData["name"];
	
	//print form for requesting answer key
	//save answer key as session variable
	
	$_Session["key"] = $keyPuzzle;
	$_Session["puzzleName"] = $puzzleName;
	
	print <<<HERE
	
	<form action = "wordfindkey2.php"
		  method = "post"
		  id = "keyForm">
		  
	<div>
	<input type = "submit"
		   value = "show answer key" />
	</div>
	</form>

HERE;
}

Re: session variable problem

In wordfind.php, when you set the session variables, the session variables should be capitalized like this.

php Syntax (Toggle Plain Text)
$_SESSION["key"] = $keyPuzzle;
$_SESSION["puzzleName"] = $puzzleName;
$_SESSION["key"] = $keyPuzzle;
$_SESSION["puzzleName"] = $puzzleName;

Re: session variable problem

You have named $_SESSION correctly in the second file, but have named it $_Session (incorrect) in the first. Variables are case sensitive.

Re: session variable problem

wow, i feel stupid, i know i have to have it as $_SESSION but didnt realize that was the problem. I put it as $_SESSION["key"] and such. It works fine, thanks guys.
