Code Igniter POST Variable

Question

Hi Everyone!

I am brand new to Code Igniter but I can't seem to find a way to do this in the documentation, In normal PHP you can retrieve the contents of the entire POST variable like this

$_POST = $postedVars

But I can't seem to find something that does this in the same manner, I've tried

$arr = $this->input->post;

and

$arr = $this->input->post();

With no luck! Is this possible in CI? Thanks in advance!

First, you need a form or something that sets the variables Then, you retrieve them.

$this->input->post('first_name').

You are missing the name of the variable!

The signup form:

echo form_open('CHome/signup');
$data=array('name'=>'first_name', 'id'=>'first_name','size'=>40,'value'=>set_value('first_name'));
echo "<p><label for='first_name'>First Name </label>";
echo form_input($data);
echo form_submit('submit','Make Account');

The Model:

 function addUser(){
    //you should use $this->input->post('first_name')
            $data=array(
                'first_name'=>db_clean(ucfirst($_POST['first_name'])), //db_clean is a custom func
                'last_name'=>db_clean(ucfirst($_POST['last_name'])),        
                'email'=>db_clean($_POST['email']),            
                'username'=>db_clean($_POST['username']),
                'password'=>db_clean(sha1($_POST['password1'])),            
                'type'=>db_clean('user'),
            );

            $this->db->insert('users',$data);
        }

Codeigniter stores sessions in cookies, it's all weird. I suggest just using PHP's native sessions, such as $_SESSION['first_name']. Make sure to write "session_start();" in your controller/model so you can use sessions!! (usually do it in the constructor)
