3 * module_uninstall.php performs reversion of module_install.php
\r
7 * the line below safe-guards this file from being accessed directly from
\r
8 * a web browser. It will only execute if required from within an ATutor script,
\r
9 * in our case the Module::uninstall() method.
\r
11 if (!defined('AT_INCLUDE_PATH')) { exit; }
\r
15 * the following code checks if there are any errors (generated previously)
\r
16 * then uses the SqlUtility to run reverted database queries of module.sql,
\r
17 * ie. "create table" statement in module.sql is run as drop according table.
\r
19 if (!$msg->containsErrors() && file_exists(dirname(__FILE__) . '/module.sql')) {
\r
20 // deal with the SQL file:
\r
21 require(AT_INCLUDE_PATH . 'classes/sqlutility.class.php');
\r
22 $sqlUtility = new SqlUtility();
\r
25 * the SQL file could be stored anywhere, and named anything, "module.sql" is simply
\r
26 * a convention we're using.
\r
