Jetpack by WordPress

So at work today we have this posted in our communal chat.

http://jetpack.me/

Took at look at the site. Figured out what it was. Its a nice little collection of plugins that Automattic make bundled into one plugin, the idea being that these are the plugins installed on Hosted blogs over at WordPress.com. I only used the WordPress.com site stats plugin, (since the whole package is available as separate plugins), which out of them all is the only one that needs linking to WordPress, so makes you wonder why after installing JetPack I need to link up to WordPress.com when the only plugin from the pack that needs it is already linked…..

Anywho that aside its a nice little plugin with a nice interface:

So hats off for that and the simple ness of installing. Just a shame that according to JetPack.me FAQ’s all the stand alone plugins are coming to a end and users will need to get JetPack in the future.

On a side note I tested the plugin on a separate domain and got this:

Twas nice of JetPack to deactivate the old/current WordPress.com stats plugin I had installed to stop conflicts 😀

Travels of a Commercial WordPress Plugin Developer 1

My job at the moment is updating and coding YourMembers, which is a commercial plugin for WordPress.

Recently I’ve been working on a method to Auto Upgrade the plugin, since commercial plugins cannot go on Extend, and there is no commercial equivalent. Extend being the WordPress plugin repository.

Commercial plugins get no nice little “Plugin needs updating Circle” on the plugins tab, or a nice little message on the plugins page, let alone access to the auto updater!

Which leaves us (commercial plugin devs) to write our own version checkers and hook in accordingly.

So now I have a nice little PHP class which will detect whether it can fwrite/rename and if not if it can FTP instead, much the same as the WordPress updater does.

Now this is all well and good, but I needed a method to download and unzip the new plugin file. Grabbing the file is easy, either file_get_contents (heaven forbid), or curl (yay for curl), and write the file (being a zip) to the web servers temporary directory and process from there.

Now the problem here is how to unzip. A Brief look at how WordPress does it seems to show it has three different methods of unzipping. So dump that.

Didn’t feel the need to use PHP’s ZipArchive class, since I don’t need to edit the zip, just extract its contents.

Off to php.net I go and I find some nice handy functions, and quite surprised to find that the zip_read function can handily recurs into directories within the zip file to return their paths/names. Mildly annoying at the time as I had gone and written a recur loop to go inside directories…. and got thrown a error, nice headdesk moment!

So basically the Zip functions, the basic ones of PHP, are actually quite nice, handy and useful!

Heres my code snippet:

<?php
class someclass() {
	private function unpack() {
		$from = $this->tmp_write;
		$to = $this->tmp_out;
		@mkdir($to);
		
		$zip = zip_open($from);
		if (is_resource($zip)) {
			$this->readzip($zip);
			zip_close($zip);
		} else {
			// failed to open
			$this->error = 1;
		}
	}
	
	private function readzip($zip) {
		$from = $this->tmp_write;
		$to = $this->tmp_out;
		
		echo '</pre><textarea style="width: 100%; height: 100px;">';
		
		while (FALSE !== ($file = zip_read($zip))) {
			$name = zip_entry_name($file);
			echo $name . "\n";
			if (!strpos($name, '.')) {
				// is dir
				@mkdir($to . '/' . $name);
			} else {
				// it recurs into directorys on its own!
				$item = zip_entry_open($zip, $file);
				$size = zip_entry_filesize($file);
				
				$read = zip_entry_read($file, $size);
				$fp = fopen($to . '/' . $name, 'w');
				fwrite($fp, $read);
				fclose($fp);
			}
		}
		
		echo '</textarea><pre>';
	}
}
?>

I just installed this code snippet plugin, which I might need to change its background colours…..

Any suggestions for code snippet plugins greatly appreciated!
