Fatal Error: Call to undefined function. - function EXISTS!

[intellectualmoron]

Hello all!

 

Im using php5.2.1 w/ mysql 5.0

 

Im having some trouble with my on of my class functions. On processing a logon, the following error occurs:

 

Fatal error: Call to undefined function generateRandID() in C:\webserver\htdocs\papple\include\session.php on line 97

 

line 97 reads:

$this->userid = $_SESSION['userid'] = $this->generateRandID();

 

generating a uid for my cookies.

 

the function that is called is:

 

function generateRandID(){

return md5($this->generateRandStr(16));

}

 

function generateRandStr($length){

$randstr = "";

for($i=0; $i<$length; $i++){

$randnum = mt_rand(0,61);

if($randnum < 10){

$randstr .= chr($randnum+48);

}else if($randnum < 36){

$randstr .= chr($randnum+55);

}else{

$randstr .= chr($randnum+61);

}

}

return $randstr;

}

}

 

Any help would be great,

Thanks in anticipation,

Moron!

$this->userid = $_SESSION['userid'] = $this->generateRandID();

 

I may not know what I am talking about since I do not have any other code to look at, but if you are trying to cal a function of a class outside the class don't you need to instantiate it? IE:

 

<?php
$genClass = new genereateClass();
$userid = $_SESSION['userid'] = $genClass->generateRandID();
?>

 

???

What I am grasping at is more code would be very helpful.

Hello Frosty, the functions are all within the same class. the session class is listed below. the generate rand ID functions ar e close to the bottom of the code.

 

Thanks,

[redbullmarky]

your class differs to your example.

 

In Session::login, this:

 

$this->userid    = $_SESSION['userid'] = generateRandID();

 

should be as it is in your first post:

 

$this->userid    = $_SESSION['userid'] = $this->generateRandID();

[intellectualmoron]

my bad. it actually reads $this->userid    = $_SESSION['userid'] = $this->generateRandID(); now...sthe error has slightly changed to :

 

Fatal error: Call to undefined method Session::generateRandID() in C:\webserver\htdocs\papple\include\session.php on line 97
