Wordpress Add custom permalink - wordpress

Question

I have a dynamic page setup in wordpress which uses a $_GET['id'] php variable to make a query to the database. The problem is that my url format looks like the following:
http://site.com/business/id?=123
What's the best way to make the url look like:
http://site.com/business/business-name-here
Is it done using rewrite rules in the .htaccess file?
Thanks in advance

I've found a great class to do just that by Kyle E try it.
<?php
/*
//Author Kyle E Gentile
//To use this class you must first include the file.
//After including the file, you need to create an options array. For example:
$options = array(
'query_vars' => array('var1', 'var2'),
'rules' => array('(.+?)/(.+?)/(.+?)/?$' => 'index.php?pagename=$matches[1]&var1=$matches[2]&var2=$matches[3]')
);
//After creating our $option array,
//we will need to create a new instance of the class as below:
$rewrite = new Add_rewrite_rules($options);
//You must pass the options array, this way. (If you don't there could be problems)
//Then you can call the filters and action functions as below:
add_action('wp_head', array(&$rewrite, 'flush_rules'));
add_action( 'generate_rewrite_rules', array(&$rewrite, 'add_rewrite_rules') );
add_filter( 'query_vars', array(&$rewrite, 'add_query_vars') );
//That is it.
*/
//prevent duplicate loading of the class if you are using this in multiply plugins
if(!class_exists('add_rewrite_rules')){
class Add_rewrite_rules{
var $query_vars;
var $rules;
function __construct($options){
$this->init($options);
}
function init($options){
foreach($options as $key => $value){
$this->$key = $value;
}
}
function rules_exist(){
global $wp_rewrite;
$has_rules = TRUE;
foreach($this->rules as $key => $value){
if(!in_array($value, $wp_rewrite->rules)){
$has_rules = FALSE;
}
}
return $has_rules;
}
//to be used add_action with the hook 'wp_head'
//flushing rewrite rules is labor intense so we better test to see if our rules exist first
//if the rules don't exist flush its like after a night of drinking
function flush_rules(){
global $wp_rewrite;
if(!$this->rules_exist()){
//echo "flushed"; // If want to see this in action uncomment this line and remove this text and you will see it flushed before your eyes
$wp_rewrite->flush_rules();
}
}
//filter function to be used with add_filter() with the hook "query_vars"
function add_query_vars($query_vars){
foreach($this->query_vars as $var){
$query_vars[] = $var;
}
return $query_vars;
}
//to be used with a the add_action() with the hook "generate_rewrite_rules"
function add_rewrite_rules(){
global $wp_rewrite;
$wp_rewrite->rules = $this->rules + $wp_rewrite->rules;
}
}
}
?>
Add the following function to the init of your plugin / functions file.
public function rewriteRules()
{
//Add the query variables to the list so wordpress doesn't discard them or worse use them to try and find by itself what page to serve.
$options = array(
'query_vars' => array('trainingid', 'vakname'),
'rules' =>
array( 'uncategorized/vak/([^/]+)/([^/]+)/?$' => 'index.php?p=1316&vakname=$matches[1]&level=$matches[2]'
)
);
//I use a autoloader but if you don't you have to include the class.
//include_once('path/to/AddRewriteRules.php');
$rewrite = new AddRewriteRules($options);
add_action('wp_head', array(&$rewrite, 'flush_rules'));
add_action('generate_rewrite_rules', array(&$rewrite, 'add_rewrite_rules'));
add_filter('query_vars', array(&$rewrite, 'add_query_vars'));
}
