Fatal error: Cannot instantiate non-existent class: gim_page in /home/.mabeloven/mecharpg/mechaasylum.com/global/game/prepare.php on line 50


What does this mean...

Spesificly this: Fatal error: Cannot instantiate non-existent class:


this is the coding for the first error:

class GIM_Country {
		var $id = -1;
		var $data = array();
		var $db = NULL;
		function GIM_Country() {
			$this->db = new GIM_DB;
		}
		function link($id) {
			if ($this->id == $id) return;
			$this->id = $id;
		}
		function fill($name, $id = -1) {
			if ($id == -1) $id = $this->id;
			$this->db->Query("SELECT $name FROM countries WHERE id='$id'");
			$this->db->Next();
			$this->data[$this->id] = $this->db->getAll();
		}
		function set($name, $val, $met = "") {
			$id = $this->id;
			if ($met != "") {
				$set = "$name = $name $met $val";
				if ($met == "+") $this->data[$id][$name] += $val;
				if ($met == "-") $this->data[$id][$name] -= $val;

			} else {
				$this->data[$id][$name] = $val;
				$set = "$name = $val";
			}
			$this->db->Query("UPDATE countries SET $set WHERE id='$id'");
		}

		function get($name, $id = -1) {
			if ($id == -1) $id = $this->id;


			if ($this->data[$id][$name] == NULL) {
				$this->db->Query("SELECT $name FROM countries WHERE id='$id'");
				$this->db->Next();
				$this->data[$id][$name] = $this->db->get($name);
			}
			return $this->data[$id][$name];
		}
		function getoil($id) {
			global $cdb;
			$cdb->query("SELECT oil FROM countries WHERE id='$id'");
			$cdb->Next();
			return $cdb->get("oil");
		}
		function getname($id) {
			global $cdb;
			$cdb->query("SELECT name FROM countries WHERE id='$id'");
			$cdb->Next();
			return $cdb->get("name");
		}
		function getlatlon($cid) {
			$db = new GIM_DB;
			$db->Query("SELECT * FROM countries WHERE id='$cid'");
			$db->Next();

			$info[0] = $db->Get("lat");
			$info[1] = $db->Get("lon");

			return $info;
		}
		function time($dist, $speed) {
			return $dist / $speed * 60 * 60;
		}
		function distance($c1, $c2, $unit = "K") {
			$l1 = $this->getlatlon($c1);
			$l2 = $this->getlatlon($c2);


			$lat1 = $l1[0];
			$lon1 = $l1[1];

			$lat2 = $l2[0];
			$lon2 = $l2[1];

			$theta = $lon1 - $lon2;

			$dist = sin(deg2rad($lat1)) * sin(deg2rad($lat2)) + cos(deg2rad($lat1)) * cos(deg2rad($lat2)) * cos(deg2rad($theta));
			$dist = acos($dist);

			$dist = rad2deg($dist);
			$dist = $dist * 60 * 1.1515;
			switch($unit) {
				case "M":
					break;
				case "K":
					$dist = $dist * 1.609344;
		      			break;
				case "N":

		  return ($dist);

'Cannot instantiate non-existent class' normally means that you have either not defined a class, or you have defined your classes in the wrong order.

Where abouts have you defined gim_db and gim_page?

oooh thanks! ill post more if i have other questions

umm... what would i put in this spot

var $cID	= 0;
           var $qID 	= 0;

i know im suposed to put somthing where the zeros r... what?

One more small tip...
Are you sure you included the class file itself in your script file?
Just in case..

ya

class GIM_DB {

		var $Hostname	= "mysql.mechaasylum.com";
		var $Username	= "this is secret...";
		var $Password	= "this is secret...";
		var $Database	= "this is secret...";
		var $cID	= 0;
		var $qID 	= 0;

		var $Record	= array();

this is the index preparing script:

 include("$dir/modules/db/db.php");
	include("$dir/modules/page/page.php");
	include("$dir/modules/info/info.php");

	include("$dir/modules/user/user.php");
	include("$dir/modules/events/events.php");
	include("$dir/modules/country/country.php");
	include("$dir/modules/province/province.php");
	include("$dir/modules/script/script.php");
	include("$dir/modules/provarlist/provarlist.php");
	include("$dir/modules/uservarlist/uservarlist.php");

That really depends what they are used for

Are you sure that GIM_DB is defined before it is used (i.e. before GIM_Country is defined)?

here is the full database script:

 class GIM_DB {

		var $Hostname	= "mysql.mechaasylum.com";
		var $Username	= "this is secret...";
		var $Password	= "this is secret...";
		var $Database	= "this is secret...";
		var $cID	= 0;
		var $qID 	= 0;

		var $Record	= array(); 

/* Connecting to DB.
		¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯*/
		function Connect() {

			if (!$this->cID) {

				$this->cID=mysql_pconnect($this->Hostname, $this->Username, $this->Password);

				if (!$this->cID) {

					$this->Halt("Couldnt connect to $this->Hostname");
					return false;
				}


				if (!mysql_select_db($this->Database,$this->cID)) {

					$this->Halt("Couldnt select $this->Database");
					return false;
				}
			}

			return true;
		}

		/* Free sql results.
		¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯*/
		function Free() {
			  @mysql_free_result($this->qID);
			  $this->qID = 0;

		}

		/* Sending Query
		¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯*/
		function Query($Query) {
			if ($Query == "") {
				//$this->Halt("Empty query");
				return 0;
			}
			if (!$this->Connect()) {
				return;
			}

			if ($this->qID) {
				$this->Free();
			}

			$start = getmicrotime();
			$this->qID = @mysql_query($Query,$this->cID);

			if (!$this->qID) {
				$this->Halt("Invalid SQL: $Query (" . mysql_error() . ")");

				return false;
			}
			$end = round((getmicrotime() - $start), 4);

			if ($end > 0.20 && 0) {
			?>
				<span class="error_msg"><pre><?= "$end sec ($Query)"; ?></pre></span><br>;
			<?
			}

			return true;
		}


		/* Get next result in array after Query()
		¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯*/
		function Next() {
			if (!$this->cID) {
				$this->Halt("Can not fetch while no query is pending...");
				return false;
			}

			$this->Record = mysql_fetch_array($this->qID);

			if (is_Array($this->Record)) return true;

			return false;

		}

		/* Get value of array fetched my Next
		¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯*/

		function Get($Name) {
			return $this->Record[$Name];
		}
		/* Get the entire result array.
		¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯*/

		function getall() {
			return $this->Record;
		}

		/* Return number of records current query has.
		¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯*/
		function affected_Rows() {
			return mysql_affected_rows($this->cID);
		}
		function num_Records() {
			return @mysql_num_rows($this->qID);
		}

		/* Something went wrong function.
		¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯*/
		function Halt($Msg = "") {
			echo $Msg;

		}
	}

well i fixed the GIM_DB problem... the other one is still open...
