How can this be a non-object?

[sifuhall]

I really like PHP, but I miss the debugging abilities of PERL.

include_once ("kwoon.php");
$newKwoon = new kwoon();
$retval = $newKwoon->kwoonVerify($kwoonname, $password, $activation);
// test for retval
if (strlen($retval) > 1) {
	$myoutput = new output();
	// display error page
	$myoutput->dispError($retval);			
	exit;
}
$newKwoon->kwoonByName($kwoonname);

//The infamous line 119 below
$newKwoon->kwoonActivate($kwoonname);

Running this results in the last line ($newKwoon->kwoonActivate) giving this error

Fatal error: Call to a member function on a non-object in /home/virtual/dragonslist/home/httpd/html/fun/game/signup.php on line 119

How can $newKwoon, that has been initialized and used twice already before this line, suddently become a non-object?

Maybe I just don't understand the error message

do you have a function kwoonActivate declared in your class ???? my guess is you don't

Thanks for the reply.

I must admit this problem doesn't make sense to me at all.

I do have the function kwoonActivate, and I was conviced the error was in there, so I reduced it to this (and still have the problem):

		// set activation flag and kwoon defaults
		function kwoonActivate() {
                               echo "test";
		}

ONe thing that strikes me as odd, and might be causing the problem is the line above line 119. In your original post on this subject

Your method

// get kwoon info by kwoon name 
function kwoonByName() { 

// database connection info 
require ("dlgame.php"); 

// check for persistant database connection 
mysql_pconnect("localhost", $dbuser, $dbpass); 

$query = "SELECT * from players where kwoon='$inputKwoonName'"; 
$result = mysql_db_query($dbname, $query); 
$kwoon = mysql_fetch_assoc ($result); 
mysql_free_result($result); 
$this = $kwoon; 
} 

function kwoonByName()

takes no parameters but you call it with one.

$newKwoon->kwoonByName($kwoonname);


This mya be part of the problem, unless of course you already fixed that part.

[sifuhall]

Yeah, I modified it to no longer user parameters in one of my many attempts to fix this.

You have a good memory!

I found the problem, but I don't understand it.

It appears the problem was in the function kwoonByName. This function takes a name and attempts to fill the object with the correct values (like the constructor, except the constructor takes the id and in this case the id isn't known, but the name is).

Here is the code, once I removed it (actually I combined it with another function) it works just fine:

		// return kwoon id by kwoon name
		function kwoonByName($inputKwoonName) {
			// database connection info
			require ("dlgame.php");

			// check for persistant database connection
			mysql_pconnect("localhost", $dbuser, $dbpass);
	
			$query = "SELECT * from players where kwoon='$inputKwoonName'";
			$result = mysql_db_query($dbname, $query); 
			$outKwoon = mysql_fetch_assoc ($result);
			$this = $outKwoon;
			mysql_free_result($result);
		}
