Dev:xoops install uninstall

From XOOPS Web Application System

onInstall, onUninstall, onUpdate

The module installation system features a way for mods to specify a custom installation / uninstallation script that will be called once the kernel has finished its own work. In xoops_version.php:

   $modversion['onInstall'] = 'install_funcs.php';
   $modversion['onUninstall'] = 'install_funcs.php';
   $modversion['onUpdate'] = 'install_funcs.php';

Then in install_funcs.php:

$xoopsMod is $XoopsModule object of that module.

   function xoops_module_install_<DIRNAME>( $xoopsMod ) {
       if (everythingIsOK) {
           return true;
       } else {
           return false;
       }
   }

   function xoops_module_uninstall_<DIRNAME>( $xoopsMod ) {
       if (everythingIsOK) {
           return true;
       } else {
           return false;
       }
   }

   function xoops_module_update_<DIRNAME> ( $xoopsMod, $oldversion) {
       switch ($oldversion) { //remember that version is multiplied with 100 to get an integer
           case 100: //perform actions to upgrade from version 1.00
               break;
           case 110: //perform actions to upgrade from version 1.10
               break;
       }
   }
