Retrieve Selected Value from drop down

[eluser]bigmac90[/eluser]
I want to retrieve the selected value from multiple drop downs so I can use a where SQL statement to retrieve data from a database. Is it possible to retrieve the value of a dropdown and if so, how do I do it? Also, I would prefer not to use Ajax but don't care if i have to.

Thanks

When the form is posted:

Code:

if ( $_POST ) {
    $dropdown1 = $this->input->post('dropdown_1');
    $dropdown2 = $this->input->post('dropdown_2');
    // Do something
}
