Call to a member function on a non-object

Hey guys. here is my setup
The first snippet is the page that I am getting the error "Call to a member function on a non-object"

I am inferring that I am doing something wrong with the $l->get_state_full();

the get_state_full function is at the bottom of the second snippet

Let me know,
Thanks

require_once($physical_path."/class/class.Location.php");
global $l;
$state = $l->get_state_full();
$meta_description        = $state."'s largest internship network - find internships and jobs locally or state wide!"; 

PHP:

class Location {
	var $domain;
	var $id;
	var $title;
	var $description;
	var $use_default;
	var $google_code;
	var $state;
	var $state_full;
	var $code_abbrev;
	
	function Location($id = -1) {
		if($id  == -1){
			$this->domain = $_SERVER["SERVER_NAME"];
			if($this->domain == 'localhost')
				$this->domain = 'www.****.com';	
			if($this->domain == '**.**.***.**'){
				$this->domain = 'www.****.com';
			}
			if(substr($this->domain,0,4) != "www."){
				$this->domain = "www.".$this->domain;
			}
			$q = "SELECT * ".
			     "FROM locations " . 
				  "WHERE domain = '$this->domain'";
			//echo $q;
		} else {
			$q = "SELECT * ".
			     "FROM locations " . 
				  "WHERE id = $id";
		}
			//echo $q;
			$results = mysql_query($q);
			
		// If the above failed, try the domain redirection...
		if($results == false || mysql_numrows($results) == 0){
			$r = $this->check_redirect();
			$q = "SELECT * ".
			     "FROM locations " . 
				  "WHERE id = $id";
			$results = mysql_query($q);
		}
		
		// If either of these worked, process the data
		// If none of them worked, you're shit out of luck. 
		if($row = mysql_fetch_array($results)){
			
			$row = filter_record($row);
			$this->id = $row["id"];
			$this->domain = $row["domain"];
			$this->title = $row["title"];
			$this->google_code = $row["google_id"];
			$this->use_default = $row["use_default"];			
			$this->state = $row["state"];
			$this->code_abbrev = $row["code_abbrev"];
			
			$this->state_full = $row["state_full"];
			
		}else {
			$this->title = " - Not available - ";
			$this->description = " - Not available - ";
		}
	}

	function get_state_full(){
		return $this->state_full;
	
	}

PHP:

 

The error message is saying $l is not an object. I can't be any more specific with the code you've given but for whatever reason, $l is not what you're expecting it to be.

 

$l = new Location; //<------initialize your class object first before you use it

global $l; //<--you don't need a global, only use global if you inside function.

require_once($physical_path."/class/class.Location.php");

$l = new Location;
$state = $l->get_state_full();
$meta_description        = $state."'s largest internship network - find internships and jobs locally or state wide!";
