Hash symbol in URL causes a problem

Hi
I'm currently using Codeigniter version 3.0rc3, but I've had the same problem in version 2.2 as well

My routes.php look like this

PHP Code:

$route['event/:num'] = "events/event"; 


config.php

PHP Code:

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-'; 


If I try to reach, for example

Code:

http://example.com/event/32

I'm getting expected results

If I try to reach

Code:

http://example.com/event/asd

I'm getting 404 Page Not Found
Also expected

If I try to reach

Code:

http://example.com/event/+34

I'm getting An Error Was Encountered The URI you submitted has disallowed characters.
Also expected

But I try to reach the same controller with just a hash symbol

Code:

http://example.com/event/#

I'm getting a database error because of if

I would appreciate if somebody could help me fix this problem.
Thanks.

What does your events/event controller/method look like? How are you using the 3rd parameter (id) sent to it? Are you just running a query on the database to retrieve data for id "#"? I'm guessing that's where the issue is as I have no problem using #, however my segments DONT start with #, they're like site.com/controller/method#something

As CroNiX mentioned, this is most likely an issue with how you are handling your input.

In most cases, the # will not be included in the value checked against permitted_uri_chars (especially when the # is after the last slash in the URI), because the URI is passed through PHP's parse_url() function and the path and query portions are extracted, which do not include the #.

The actual database error (or at least the relevant part of it) would probably help determine what is happening, as I can't be sure whether you're receiving no input or receiving '#' as an input.

Thank for the answers guys

I'm aware that my ID is # because I set that variable just like this

Code:

$id = $this->uri->segment(2);

...assuming that $this->uri->segment(2) is nothing but number, like I remapped it in routes.php

Code:

$id = $this->uri->segment(2);

...assuming that $this->uri->segment(2) is nothing but number, like I remapped it in routes.php

Never assume anything coming from user input. You should type-cast to integer to be safe and minimize risk of SQL injection:

PHP Code:

$id = (int)$this->uri->segment(2);
