This is my controller:

class Timesheet extends Controller {

    ...

    function index() {
        //loads view with a form that submits to "timesheet/change_date"
    }

    function summary() {
        //loads view with a form that submits to "timesheet/change_week"
    }

    function change_date() {
        ...
        redirect('timesheet');
    }

    function change_week() {
        ...
        redirect('timesheet/summary');
    }

    ...

}

The first form is located at http://localhost/dts/index.php/timesheet and when I submit the change_date form, it correctly goes thru the change_date() function and re-loads http://localhost/dts/index.php/timesheet correctly.

However, the second form is located at http://localhost/dts/index.php/timesheet/summary, and when I submit the change-week form, it goes thru the change_week() function but goes to http://localhost/dts/index.php/timesheet/timesheet/change_week. Notice the word timesheet is repeated. When I submit the form again, another timesheet is added.

What's wrong and how do I improve my code?

My .htaccess is below:

RewriteEngine on
RewriteCond $1 !^(index\.php|webroot|robots\.txt)
RewriteRule ^(.*)$ index.php/$1 [L]
