[wp-hackers] Site Address during development

Hi All,

I've had exactly the same problem so I wrote a plugin to address it. Please take a look:  


It's goal is to provide a one-click content migration process in the admin. To enable it you "register" all the data about your different hosts in /wp-config.php. Below are examples of the standard information that can be registered but anything that is different can be included such as Google Map API keys:

 'database'  => 'example_db',
 'user'      => 'example_user',
 'password'  => '12345',
 'host'      => 'localhost',
 'sitepath'  => '',        // '' if WordPress is installed in the root
 'name'      => 'Example Local Development',
 'host'      => '',
 'domain'    => 'example.dev',
 'rootdir'   => '/Users/mikeschinkel/Sites/example/trunk',
 'name'      => 'Example Test Server',
 'rootdir'   => '/home/example/public_html/test',
 'domain'    => 'test.example.com',
 'name'      => 'Example Staging Server',
 'rootdir'   => '/home/example/public_html/stage',
 'domain'    => 'stage.example.com',
 'name'      => 'Example Live Site',
 'rootdir'   => '/home/example/public_html/',
 'password'  => '%asd59kar12*fr',
 'domain'    => 'www.example.com',

It is designed to do the standard migrations that have been discussed on this thread but be hookable so any new migration needed because of a new requirement introduced by a plugin can quickly be coded and incorporated into the migration process.  And it can migrate the content from all servers to the current server based on the current URL.

It works by replacing DB_HOST, DB_USER, DB_NAME, DB_PASSWORD, etc. in /wp-config.php because it sets those for you based on the current site's URL matching one of the defined hosts. But you can easily revert back to standard all DB_* defines at any time by just commenting the host registration code out or deleting it and putting the DB_* defines back in page.  Note that Nacin (or maybe it was Lebens) saw this at WordCamp Savannah and reacted that end users would be confused by rootdir, which is optional (of course if it's not provided you don't migrate things like upload direction.) So realize this is NOT for end users; it is designed for professionals like those who commented on this list who need to work with dev, test, stage and production servers and it can go away when the project is done if that's what's appropriate. 

A writeup about it is here:


Would love to have all of you who are struggling with this to try it and to get your feedback on how well it resolves your use-cases.
