Installation

• Copy the update folder to your project (what should be updated)
• Create a update.ini on your server (where the updates are from)

Important: Please notice that PHP needs write permissions to update the files on your webserver

Description

The update folder consists of two files:

• index.php - includes the class and calls the update
• update.php - update class

You should not call the update out of your project (what happens if you try to update a file which is in use at the moment?). At your server you need a folder with a configuration file update.ini and the ziped versions.

update.ini

The update.ini should look like this:

[1]
version = 0.1
url = http://example.com/updates/0.1.zip

[2]
version = 0.2
url = http://example.com/updates/0.2.zip

You can name the versions whatever you want but the sections (for example [1]) has to be an integer so that the class can compare the versions. You cannot compare 1.4.3-13.r1441 with 1.4.3-12.r1445 without problems. The url has to be absolute.

Update files

Zip your project and rename it to version.zip. The zip file should include all of the project files.

Check for an update

/*
 * Index.php in the folder update
 */

require('update.php');

$update = new AutoUpdate(true); //Enable logging

$update->currentVersion = 1;

/*
 * In this example the folder 'updateUrl' includes 3 files, 0.1.zip, 0.2.zip and update.ini
 */
$update->updateUrl = 'http://example.com/updates';

$latest = $update->checkUpdate();

if ($latest !== false) {
	if ($latest > $update->currentVersion) {
		//Install new update
		echo "New Version: ".$update->latestVersionName."<br>";
		
		//You can also stop here and let the user decide when to update.
		echo "Installing Update...<br>";
		if ($update->update()) {
			echo "Update successful!";
		}
		else {
			echo "Update failed!";
		}
		
	}
	else {
		echo "Current Version is up to date";
	}
}
else {
	echo $update->getLastError();
}
