How to return data based on the email which I have in the sessions within codeigniter?

Question

I'm trying to build a site with codeigniter and when a user logs in I am able to get the email address they logged in with from the sessions data so I therefore can pin point their record which is in the database.

At the moment I am only able to get these records by querying the database where $email = email blah blah and doing a foreach statement which isn't ideal. I would rather be able to get the users id via the email address which has been passed in the sessions. Then pass the id into the urls for each item of the navigation menu when they log in and get the content this way.

Not sure if I'm being clear but what I need help with is:

1. Get the correct record from the database based on the session email

2. Creating dynamic URLs which pass the users id into each item of the navigation menu once logged in

3. Display that users content based on the id which is in the url

I have this for the function in my controller at the moment:

$email = $this->session->userdata('email');
$query = $this->db->get_where('users', array('email' => $email));

    foreach($query->result_array() as $result){
        echo $result['id'];
    }

So I'm unsure of what I need to do, getting muddled up, any help is greatly appreciated!

Since you're expecting a single row you can use $query->row_array().

$email = $this->session->userdata('email');
$query = $this->db->get_where('users', array('email' => $email));

$user = $query->row_array();

echo $user['id'];
