Open Source ACH was developed on a Linux machine with an Apache server with PHP 5.2 and MySQL 5; it might work with earlier versions but has not been tested on them.
It has been successfully installed, with modifications, on a Windows server.
Because this is a Web application, you cannot install it on an ordinary desktop computer. To make that happen, you should install a tool like XAMPP. If you're interested in using Open Source ACH but don't have access to a Web server, stay tuned: we will have an online version ready in the near future.
1: At the top of parts/includes.php, edit the following lines to reflect your environment, replacing SITEURL with your own domain. Include trailing slashes (eg. domain.com/ instead of domain.com).
<base href="http://SITEURL/"> <?php $base_URL="http://SITEURL/"; $email_domain="SITEURL"?>
2: In code/common_db.php, add your database connection details:
$dbhost = 'HOST'; $dbusername = 'DBUSER'; $dbuserpassword = 'DBUSERPASSWORD'; $default_dbname = 'DBNAME';
3: Create your database and run the MySQL script to create the tables.
4: If you want to install ACH into a subdirectory so that it runs from, for example, domain.com/ach, you must edit line 3 of the .htaccess file to read
If pages do not load correctly after completing the above, the problem may be with your server settings. If possible, change your Apache vhost configuration file by altering the directory-level settings to the following (or add them if none exist):
<Directory /path/to/remote/root/> Options Indexes FollowSymLinks AllowOverride All Order allow,deny allow from all </Directory>
PHP should have the short_opentag setting turned on. You can verify this either with a phpinfo page, or by editing your php.ini file.
