Updates help us and you keep your copy up-to-date. With updates, new features and other improvements are added to the script. Within a single update there can be different builds with minor fixes. The update and build number is written at the end of each page.

Click Maintenance - Update in the admin panel or run in the shell

cd your_path_to/scj/admin/
php update.php

and the script will be updated to the current version

Update 1

In version 1 each update had to be installed sequentially

cd your_path_to/scj/admin/
php update.php update_number


for example if you are on 49 and need to reach 52

php update.php 50
php update.php 51
php update.php 52

• Base command to run all updates. It will update your script to the latest version

cd /path_to_scj/admin; env HTTP_HOST=yourdomain.com php update.php

cd /path_to_scj/admin; env HTTP_HOST=yourdomain.com php update.php update_number
for example
cd /home/vasya/domain.com/scj/admin; env HTTP_HOST=domain.com php update.php 45

update.php source code

<?php
	require('../includes/prepare.php');
	require('../includes/libs/http_functions.php');

    // out of space fix
    $df = disk_free_space("./");
    if ($df < 5*1024*1024) {
    	die("No enough space for update");
    }

	// slow connection fix
	$mysql_version = db_value('ver', 'select version() as ver');
	if (stristr($d['ver'], '5.')) {
		db_query("set wait_timeout=240");
	}

	if ($argv[1] != '')  {
		$num = (int) $argv[1];
		if ($num > 0) {
			ProcessUpdate($num);
			exit;
		}
	}

	$tmp = get_url("http://smartcj.com/smartnews.php?action=last_update");
	if ($tmp['status'] != 200) {
		die("Can not get last update number, please, contact support");
	}

	$last_script_version = $tmp['body'];

	if ($last_script_version == $settings['last_update_number'] and !$_REQUEST['force_update']) die("You have the lastest version.");

	while ($settings['last_update_number'] < $last_script_version) {

	global $settings;

	$tmp = get_url("http://smartcj.com/updates/".(int)$update_id."/update.txt");
	if ($tmp['status'] != 200)  {
		echo "Sorry, can not find  update {$update_id}";
		return false;
	}
	$_REQUEST['terms_read'] = true;
    ob_start();
	eval ('?>' . $tmp['body']);
	$res = ob_get_clean();
	$res = str_replace('<br>', "\n", $res);

You can create a file, for example update.sh, which contains lines like this:

cd /path_to_domain/scj/admin; env HTTP_HOST=yourdomain.com php update.php
cd /path_to_domain2/scj/admin; env HTTP_HOST=yourdomain2.com php update.php

and so on for as many lines as needed. And run it from the shell

sh update.sh

During installation and update, the script does not write index.php or any files to the domain root, so as not to accidentally overwrite anything you have there. Accordingly, during updates, the question arises of copying the Smart index if it is used on the domain root. There are 2 options:

1. add lines like cp ../cgi/index.php ../../index.php to update.sh
2. or at installation time, do not copy the index, but make a symlink to the corresponding directory.

The only way is if you have a backup from the version you need.

You need to install the script of that version and upload the backup of the MySQL database from the same version.

You cannot just upload a backup of MySQL from version 44 to version 45 script for example.

Update can be a fairly heavy procedure for the server, and some pages may be incorrectly cached, etc. Some services, for example in case of a major update release, usually do this at night and close the site, showing a standard message that the service will be available in a few hours. But if you don't want to interrupt operations, you can do it as follows. To do this you need to

1. Install the script on another (sub)domain, ideally on a different server
2. Upload the database from the main domain there
3. Run the update on this separate subdomain
4. All heavy database procedures will run there, while the main site remains unaffected
5. Transfer the database from the auxiliary domain to the main one
6. Perform the update on the main - it will go quickly as the database is already changed, you only need to download the files.
