Dealing with url request in CodeIgniter

I just started learning codeigniter and i must say its pretty easy but I have a problem dealing with wrong urls, for example:

if I have an anchor tag like this http://example.com/info/2 in the controller if I have 

public function info( $x ) {
   $data['body'] = "Personal_info";
   $data['details'] = $this->person_model->get_detail( $x );
   $this->load->view('view', $data);
}

the controller grabs the links 

segment (3)

and then grab the details of the id from the database. now for instance if a user manually edit the link on the browser and change the 

segment(3)

to lets say 7 and there is no id in the database as 4.

how do I handle such a problem? I am a beginner so please pardon me

You could use empty method to check if there is data and if not redirect away from the page.

public function info( $x ) 
{
    $details = $this->person_model->get_detail( $x );
    if(empty($details))
        redirect('other/url');

    $data['body'] = "Personal_info";
    $data['details'] = details;
    $this->load->view('view', $data);
}

This way it doesn't throw errors and potentially attempt to display something that doesn't exist.

you can check if the passed id exists in database before trying to fetch related data, like:

$data_exists = $this->person_model->data_exists( $x );
if( $data_exists ) {
    $data['details'] = $this->person_model->get_detail( $x );
    $this->load->view('view', $data);
}
else {
   //load some view for showing no such id exists in db
}

where data_exists() can be a function in model which returns TRUE or FALSE depending on existance of your id in database.
