On a recent project i had to use sortable a LOT. I mean over 3-4 different sortable on page. So, how i manage to avoid heavy code?

One function to rule them all:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

$('.sortable').each(function(){
	var _t = $(this);
	_t.sortable({
		handle:'.move',
		items:'dd',
		update:function(){
			$.ajax({
				type: "POST",
				url: $(this).find('a.move:eq(0)').attr('href'),
				data: _t.sortable('serialize'),
				cache: false
			});
		}
	});
});

The HTML markup (for two sortables) is this:

1
2
3
4
5
6
7
8
9
10

<dl class="sortable">
	<dd id="sotableEl1-1"><a href="updateUrl.php?id=sortableID-1" class="move">move</a></dd>
	<dd id="sotableEl1-2"><a href="updateUrl.php?id=sortableID-1" class="move">move</a></dd>
	<dd id="sotableEl1-3"><a href="updateUrl.php?id=sortableID-1" class="move">move</a></dd>
</dl>
<dl class="sortable">
	<dd id="sotableEl2-1"><a href="updateUrl.php?id=sortableID-2" class="move">move</a></dd>
	<dd id="sotableEl2-2"><a href="updateUrl.php?id=sortableID-2" class="move">move</a></dd>
	<dd id="sotableEl2-3"><a href="updateUrl.php?id=sortableID-2" class="move">move</a></dd>
</dl>

This means that you don’t need to use an ID for each sortable. Instead, you add the id to the update URL, on MOVE handler (which MUST be a link). I think this is pretty simple and useful trick.

• OXID eSales is an Open source e-shop which can be a better alternative to OSCommerce, Zencart, and other ANTIQUE shops.
• If I start talking about shops, take a look at simpleCart(js). You don’t need nothing but a paypal account and few minutes to set up. No PHP, no MySQL, no nothing (but if you want, you can use).
• And the last link for shops will get you to Sitepoint: How to pick the right shopping cart? Seven carts reviewed
• Sort your tables with no effort and no huge libraries like prototype or jquery (even if I am a big fan of jQuery, I can’t use it on every single project, especially when is a small project)
• Kaltura - Open source video platform. Which mean you can start your own youtube and hope that google will buy you

• Do you really need version control for your code? These guys convinced me i do. And bonus, review of few version control systems on smashingmagazine.
• Absolutely FREE CSS menu framework.

Most of bloggers have a problem with spam. Of course, there is Akismet, but sometimes Akismet is not good enough because he doesn’t catch all spam messages. So, with this in mind, i wanted only to get rid of all automated messages.

So, look what i did:

First of all, i go with „robots fills ALL fields with something” in my mind. I’ve added only TWO lines of code: one in comments.php from your theme folder and one in wp-comments-post.php from your root folder.

Ok, how you do it?

First of all you need a ftp client and a text editor. E-texteditor is 2 in 1 so you can download a trial version for doing this. Ofcourse, you can use the old and ugly notepad (or whatever your OS has default).

Open comments.php (which is in your wp-content/themes/your_theme_name folder) then find this line:

<form action="<?php echo get_option('siteurl'); ?>/wp-comments-post.php" method="post" id="commentform">

Some things can vary (like ID of the form), but 90% in cases you won’t need to look for something else

Just AFTER this line you add:

<p style="position:absolute; left:-9999px;">Don't fill this! <input type="text" name="name2" /></p>

We put a form here and hide it. I didn’t use display:none because i wanted to be sure that field will be showed up, even is on the left side of the screen (you should actually turn you head to left to see it ) So the bot will actually SEE that form and will fill. Normal user won’t.

Save and upload (or just save if you work directly on ftp) then open wp-comments-post.php from your root folder. Just after the

<?php
/**
 * Handles Comment Post to WordPress and prevents duplicate comment posting.
 *
 * @package WordPress
 */

beginning part, just add this:

if( $_POST['name2']!= ''){
	die('Spammer!');
}

Save and upload.

Next you need to… Hmm… You don’t need to do anything else ! Now empty your Akismet queue and wait to see if you get any other spam messages

Note that is possible to not catch ALL spams, but those are automated you won’t get it anymore Also, when you upgrade wordpress make sure you make those changes again. And finally, BACK UP FIRST!
