Question

I am having a problem. I can't display the weekdays. So when I click next it should display the week for nextweek displaying Monday to Friday. And when I click previous it should display lastweek Monday to Friday

here's my code

in controller

    <?php
        public function calendar($dt) {
    //         = date("Y/m/d");
            $beginDate = $dt;
            $endDate = date("Y-m-d", strtotime($dt . "+6 days"));

            $posts = $this->Post->getWeekPosts($beginDate, $endDate);
            $members = $this->Post->PostgetUniqueMembers($posts);
    //        $week = $this->Post->weekNo($beginDate, $endDate);

            $this->set("posts", $posts);
            $this->set("members", $members);
            $this->set("begin", $beginDate);
    //        $this->set("week", $week);
        }


in view

<div id="content">
        <span id="calendar-week">
