In the previous post about adding and viewing the blog post. This post is about creating the dashboard for the blog. Create dashboard.php. Add the following.
[sourcecode language=”php”]
<?php
try {
$mongodb = new Mongo();
$articleCollection = $mongodb->myblogsite->articles;
} catch (MongoConnectionException $e) {
die(‘Failed to connect to MongoDB ‘.$e->getMessage());
}
$currentPage = (isset($_GET[‘page’])) ? (int) $_GET[‘page’]
: 1;
$articlesPerPage = 5;
$skip = ($currentPage — 1) * $articlesPerPage;
$cursor = $articleCollection->find(array(),array(‘title’,
‘saved_at’));
$totalArticles = $cursor->count();
$totalPages = (int) ceil($totalArticles / $articlesPerPage);
$cursor->sort(array(‘saved_at’=>-1))->skip($skip)
->limit($articlesPerPage);
?>
<html>
<head>
<title>Dashboard</title>
<link rel=”stylesheet” href=”style.css”/>
<style type=”text/css” media=”screen”>
body { font-size: 13px; }
div#contentarea { width : 650px; }
</style>
</head>
<body>
<div id=”contentarea”>
<div id=”innercontentarea”>
<h1>Dashboard</h1>
<table class=”articles” cellspacing=”0"
cellpadding=”0">
<thead>
<tr>
<th width=”55%”>Title</th>
<th width=”27%”>Created at</th>
<th width=”*”>Action</th>
</tr>
</thead>
<tbody>
<?php while($cursor->hasNext()):
$article = $cursor->getNext();?>
<tr>
<td>
<?php echo substr($article[‘title’], 0, 35)
. ‘…’; ?>
</td>
<td>
<?php print date(‘g:i a, F j’,
$article[saved_at’]->sec);?>
</td>
<td class=”url”>
<a href=”blog.php?id=<?php echo $article[‘_id’];
?>”>View
</a>
</td>
</tr>
<?php endwhile;?>
</tbody>
</table>
</div>
<div id=”navigation”>
<div class=”prev”>
<?php if($currentPage !== 1): ?>
<a href=”<?php echo
$_SERVER[‘PHP_SELF’].’?page=’.($currentPage — 1);
?>”>Previous </a>
<?php endif; ?>
</div>
<div class=”page-number”>
<?php echo $currentPage; ?>
</div>
<div class=”next”>
<?php if($currentPage !== $totalPages): ?>
<a href=”<?php echo
$_SERVER[‘PHP_SELF’].’?page=’.($currentPage + 1);
?>”>Next</a>
<?php endif; ?>
</div>
<br class=”clear”/>
</div>
</div>
</body>
</html>
[/sourcecode]
Then create edit.php and delete.php pages. edit.php
[sourcecode language=”php”]</div>
<div class=”separator” style=”clear: both; text-align: left;”>
<?php
$action = (!empty($_POST[‘btn_submit’]) &&
($_POST[‘btn_submit’] === ‘Save’)) ? ‘save_article’
: ‘show_form’;
$id = $_REQUEST[‘id’];
try {
$mongodb = new Mongo();
$articleCollection = $mongodb — ->myblogsite->articles;
} catch (MongoConnectionException $e) {
die(‘Failed to connect to MongoDB ‘.$e->getMessage());
}
switch($action){
case ‘save_article’:
$article = array();
$article[‘title’] = $_POST[‘title’];
$article[‘content’] = $_POST[‘content’];
$article[‘saved_at’] = new MongoDate();
$articleCollection->update(array(‘_id’ => new
MongoId($id)),
$article);
break;
case ‘show_form’:
default:
$article = $articleCollection->findOne(array(‘_id’ =>
new MongoId($id)));
}
?>
<h1>Blog Post Creator</h1>
<?php if ($action === ‘show_form’): ?>
<form action=”<?php echo $_SERVER[‘PHP_SELF’];?>” method=”post”>
<h3>Title</h3>
<p><input type=”text” name=”title” id=”title” value=”<?php echo $article[‘title’]; ?>”></p>
<h3>Content</h3>
<textarea name=”content” rows=”20"> <?php echo $article[‘content’]; ?>
</textarea>
<input type=”hidden” name=”id” value=”<?php echo
$article[‘_id’];?>”>
<p>
<input type=”submit” name=”btn_submit” value=”Save”>

}
$articleCollection->remove(array(‘_id’ => new MongoId($id)));
