Get Querystring in Codeigniter Project

In most of the codeigniter project it is turned off the querystring. And We can easily do anything without enabling the query-string because we can do everything by segment.

Now coming to the point. If you are integrating a payment system in your application and the payment gateway return you like the following method : ... bla

then you should think about enabling the query-string.

But enabling query-string by the config it may turned off the segment. It is a great problem.

So what can we do? There is a good solution for that. Here goes the solution:

 $query_str = $_SERVER['QUERY_STRING'];
 $req_uri = $_SERVER['REQUEST_URI'];
 $org_query = substr($req_uri, strlen($query_str)+1);
 parse_str($org_query, $_GET);

Now we can get the query string by :

$myOrder = $_GET['</code><code>ORDER_ID</code><code>'];

Isn’t very simple? Happy coding ………….

    Cool, but I use below solution for my CI project so I am sharing it with you.

    in controller method:

      parse_str($_SERVER['QUERY_STRING'], $_GET); 

    and in config.php the following change

    $config['uri_protocol']	= "PATH_INFO";
    $config['permitted_uri_chars'] = '';

    and in .htaccess file

    RewriteEngine on
    RewriteCond $1 !^(index\.php|images|robots\.txt)
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php/$1 [L]

      Yeah, Shaon vai it seems ok but you need to change the .htaccess and config but I tried to do it without changing anything 🙂 Anyway like your solution also.

    Maybe I’m doing something wrong, but using Mahmud Ahsan solution i had problem with pagination. To solve this issue I had to combine both solutions, and seems to work perfectly 😀
