# Software architecture
|
|
|
|
## Program flow
|
|
|
|
`init.php`
|
|
: Initializes common values
|
|
|
|
`router.php`
|
|
: Receives every external HTTP request from the web server, executes actions required in any case, executes matching code in `pg-act` if appropriate, and calls `view.php` either way.
|
|
|
|
`pg-act/`
|
|
: Executed when a form is submitted: checks that every parameter is valid and secure, then executes the feature of the page according to the parameters.
|
|
|
|
`view.php`
|
|
: Displays global HTML and includes matching file from `pg-view`.
|
|
|
|
`pg-view/`
|
|
: Displays the main page content (notably HTML forms), may sometimes display form output passed through the `$data` array.
|
|
|
|
The `output` function is used to return success or error messages and stop processing of the request.
|
|
|
|
## Other components
|
|
|
|
`fn/`
|
|
: Functions, grouped by concerned service
|
|
|
|
`jobs/`
|
|
: CLI scripts
|
|
|
|
`sftpgo-auth.php`
|
|
: When someone tries to log in over SFTP, SFTPGo sends username and password to this script, which queries the database and replies whether authentication succeeded or not.
|
|
|
|
`DOCS/`
|
|
: Documentation (some important or standard files may be directly in the root)
|
|
|
|
`css/`
|
|
: Each `.css` file in this directory is declared in every page.
|
|
|
|
`db/`
|
|
: SQlite database, the only directory writable by the program
|
|
|
|
`locales/`
|
|
: Gettext translations, see [translation.md](translation.md)
