Install updates on client system

[gr8abbasi]

Hi,

 

I want to install updates on the client system if any updates are available on the central server. So Please can anyone help me in retrieving the directories and files on central server, so that i can compare them with the clients version and if files on central server are updated then update the client files too.....

 

So what will be the best solution for it?

 

 

Thanks in advance

Use Subversion it will tell you exactly which files are updated since the last checkout.

Thanks ignace for your reply,

 

Is there any other way to do this using php?

PHP execute server side so no, your solution need to execute on the client.

the only way you can do is

have a  file version file in both client sever, and central server

have the client (your visitors, the admin), load the current server's file version

have a iframe to load central server's version

in the iframe, use parent.document.getElementById("version")==document.getElementById("serverversion")

I doubt he will be able to write his own version control system using something like Subversion is really his best option as all he'll have to do is:

 

cd /path/to/web/root/

svn update

 

You can use hooks but I do not recommend it as you don't want an unstable copy on the production server.

Thanks for your replies.

Depends how does WP do it's update? Automatic? Or does it just tell you there is a new update and refers you to the download site?

@ignace:

 

wordpress shows the link to update and on clicking that link it installs the updates while stays on your own site. So you never need to go to any site or anything else.

 

Thanks

Most probably they contact an interface that communicates with the version control system and returns the updated files since your release version.

plz can you give me some example, how it can be done...

 

Thanks

PHP execute server side so no, your solution need to execute on the client.

I think he means a web-app which can update on a single click or maybe auto-update using cron.

 

@OP:

You can create a php file on central server which simply echoes (or displays xml) latest version of software available.

You can then use curl to download the archive on to client server, use zip libraries to extract the files and redirect the client-browser to upgrade.php or something.
