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">
<!-- <h2> week <?php echo $week; ?> <?php echo date("F Y", strtotime($begin)) ?> </h2>-->
<h2> week <?php echo date("F Y", strtotime($begin)) ?> </h2>
Previous |
Next
</span>
<div id="calendar">
<table>
<tr id="calendar-names"><!-- member names -->
<td> </td>
<?php foreach ($members as $member) { ?>
<td><p><?php echo $member ?></p></td>
<?php } ?>
</tr>
<?php
foreach ($posts as $key => $post) {
?>
<tr>
<td class="calendar-background-days"><p class="calendar-days"><?php echo date("D", strtotime($key)) ?></p></td>
<?php foreach ($members as $memberKey => $member) { ?>
<td class="calendar-background-content">
<?php foreach ($post as $contentKey => $content) { ?>
<?php if ($contentKey == $memberKey) { ?>
<?php foreach ($content as $c) { ?>
<p><?php echo $c['Post']['content'] ?></p>
<?php } ?>
<?php
}
}
?>
</td>
<?php } ?>
</tr>
<?php } ?>
</table>
</div>
</div>
in model
public function getWeekPosts($begin, $end) {
$res = $this->find("all", array("order" => array('deadline', 'member_id'), "conditions" => "deadline BETWEEN '" . $begin . "' AND '" . $end . "'"));
$res = $this->formatWeekPosts($begin, $res);
return $res;
}
public function formatWeekPosts($begin, $res) {
$dt = array();
for ($i = 0; $i < 6; $i++) {

$posts[$d][] = $r;
}
}
}
$sortedPosts = array();
foreach ($members as $member) {
foreach ($posts as $key => $postDate) {
foreach ($postDate as $key2 => $p) {
if ($p["Post"]['member_id'] == $member) {
$sortedPosts[$key][$p["Post"]['member_id']][$key2] = $p;
}
}
}
}
ksort($sortedPosts);
return $sortedPosts;
}
public function PostgetUniqueMembers($posts) {
$members = array();
foreach ($posts as $post) {
