<?php
include 'include/funkcje.php';
 
$id = $_GET['id'];
$code = $_GET['code'];
 
if ($id&&$code)

	$check = mysql_query("SELECT * FROM users WHERE user_id='$id' AND user_code_activation='$code'");
	$checknum = mysql_num_rows($check);
 
	if ($checknum==1)
	{
 
		$acti = mysql_query("UPDATE users SET user_activated='1' WHERE user_id='$id'");
		die("Użytkownik został aktywowany.");
 
	}

}else
die("Data missing!");

Cytat z manula do wartości zwracanych z mysql_query:

Return Values

For SELECT, SHOW, DESCRIBE, EXPLAIN and other statements returning resultset, mysql_query() returns a resource on success, or FALSE on error.

For other type of SQL statements, INSERT, UPDATE, DELETE, DROP, etc, mysql_query() returns TRUE on success or FALSE on error.

The returned result resource should be passed to mysql_fetch_array(), and other functions for dealing with result tables, to access the returned data.

Use mysql_num_rows() to find out how many rows were returned for a SELECT statement or mysql_affected_rows() to find out how many rows were affected by a DELETE, INSERT, REPLACE, or UPDATE statement.

mysql_query() will also fail and return FALSE if the user does not have permission to access the table(s) referenced by the query.
