[SOLVED] Call to a member function....on a non-object

Akenatehm · June 30, 2009

Hey Guys,

A bit of a problem here with a small Membership Class that I am working on.

Here's the error:

Fatal error: Call to a member function checkEmail() on a non-object in /Library/WebServer/Documents/projects/sample/register.php on line 78

Here's Member.class.php:

<?php

class Register{
private $dbhost,$dbuser,$dbpass,$database,$LastResult;
public function __construct($dbhost,$dbuser,$dbpass,$database) {
       $this->dbhost = $dbhost;
        $this->dbuser = $dbuser;
        $this->dbpass = $dbpass;
        $this->database = $database;
   	}
public function checkUsername($username){
	$this->username = mysql_escape_string($username);
	$connect = mysql_connect($this->dbhost,$this->dbuser,$this->dbpass) or die(mysql_error());
	mysql_select_db($this->database) or die(mysql_error());	
	$checkuser= mysql_query("SELECT * FROM users WHERE Username = '$this->username'") or die(mysql_error());
	if(mysql_num_rows($checkuser) == 1){
		$response = "Username Already Exists <br />";
	}

mysql_close($connect);
}

public function samePasswords($password,$confirmpassword){
	$this->password = md5(mysql_escape_string($password));
	$this->confirmpassword = md5(mysql_escape_string($confirmpassword));
	if($this->password != $this->confirmpassword){
	$response = "Passwords Do Not Match<br />";	
	}	

	}

public function checkEmail($email)
	{
    	$formatTest = '/^[-\w+]+(\.[-\w+]+)*@[-a-z\d]{2,}(\.[-a-z\d]{2,})*\.[a-z]{2,6}$/i';
    	$lengthTest = '/^(.{1,64})@(.{4,255})$/';

    	$check = (preg_match($formatTest, $email) && preg_match($lengthTest, $email));
    	
    	if($check == 'false'){
    		$response = "Invalid Email<br />";
    	}
    
}      


public function createUser($username,$password,$email){
$connect = mysql_connect($this->dbhost,$this->dbuser,$this->dbpass) or die(mysql_error());
mysql_select_db($this->database) or die(mysql_error());	
$insertuser = mysql_query("INSERT into users (username,password,email) values('$username','$password','$email')") or die(mysql_error());
if($insertuser){
    	$response = "<p>Your account was successfully created. Please <a href=\"index.php\">click here to login</a>.</p>";
}

elseif(!$insertuser){
        $response = "Problem Creating User. Please Try Again Later.<br />";
}
mysql_close($connect);	


}



}
?>

and here is register.php:

<?php
session_start();
require "Connection.class.php";
require 'Member.class.php';
$select = new Connection('localhost','root','');
$select->db ('TimelessVoice');

else{

}

else{

</fieldset>
</form>
    
   <?php
}
?>
</div>
</body>
</html>

Help would be greatly appreciated as I am new to OOP with PHP.

Have you instantiated object $servervalidation?

(something like folloving)

$servervalidation = new ClassName(...) // I suppose class name is Register

$servervalidation is not object of some class type until you instantiate them
