Question

I’m using Codeigniter 2.1.3 with Friendly URL (.htaccess).

In Controller:

public function confirm($key) {
   var_dump($this->input->get());
}

But link _http://site.com/confirm/12345 returns “boolean false”.

How to enable Query strings in URL, or how to filtering $key ?

My .htaccess:

RewriteEngine on
RewriteCond $1 !^(index\.php|robots\.txt|files|templates)
RewriteRule ^(.*)$ /index.php?/$1 [L]

Answer 1

You receive key as the function argument, so you can do this:

public function confirm($key) {
   echo $key;
}

http://site.com/confirm/12345 will echo 12345.

Filtering of characters in this can be done via $config['permitted_uri_chars'] in config.php.

If you want to receive it as a GET parameter and want to perform XSS filtering on it, the URL needs to be

http://site.com/confirm?key=12345 and in your controller

public function confirm() {
   echo $this->input->get('key', TRUE);   // true implies XSS filtering
}

The second method requires $config['enable_query_strings'] to be set to TRUE.
