Create Custom Script
www.site.com/migrate.php

Change Modules with ID’s
223, 294 and 357

Change Modules with ID’s
223, 294 and 357
- “startLevel” of module with ID 233 is changed from 2 to 3.
- “menutype” is added for module with ID 294
- “You are here” text is set to “hide” for the breadcrumbs
module with ID 357.

define('_JEXEC', 1);!
!
// Connect with Joomla!
define('JPATH_BASE', __DIR__);!
require_once JPATH_BASE . '/includes/defines.php';!
require_once JPATH_BASE . '/includes/framework.php';!
!
// Database connection!
$db = JFactory::getDBO();

/**! www.site.com/migrate.php
* Module changes!
*/!
!
// Get the modules that need changes!
$query = $db->getQuery(true);!
$query->select('*')!
!->from('#__modules')!
!->where('id IN (233,294,357)');!
$db->setQuery($query);!
$modules = $db->loadObjectList('id');!
!
foreach($modules as $module)!
{!
!$module->params = json_decode($module->params);!
}

// Change startLevel!
if ($modules[233]->params->startLevel == 2)!
{!
!$modules[233]->params->startLevel = 3;!
!echo('Module [233]: startLevel: 3 ');!
}

// Set menutype!
if (empty($modules[294]->params->menutype))!
{!
!$modules[294]->params->menutype = 'mainmenu';!
!echo('Module [294]: menutype: mainmenu ');!
}

// Hide breadcrumb "You are here"!
if (!$modules[357]->params->showHere)!
{!
!$modules[357]->params->showHere = 0;!
!echo('Module [357]: showHere: 0 ');!
}

// Save new module params!
foreach($modules as $id=>$module) !
{!

!$mod !!!= new JObject();!
!$mod->id !!= $id;!
!$mod->params!= $params;!
!!
!$result = $db->updateObject('#__modules', $mod, 'id');!
}

Correct component specific
- set Access to 1 for all items in ZOO

/**!
* Component changes!
*/!
!
// ZOO access fixes!
$query !!= $db->getQuery(true);!
$fields != array('access=1');!
$conditions = array('access=0');!
$query->update($db->quoteName('#__zoo_item'))->set($fields)-
>where($conditions);!
$db->setQuery($query);!
!
$result = $db->query();!
echo('ZOO: Access set to 1 ');
