Handling Uninstallation

Uninstalling packages is as easy as installing them. Simply create a method named uninstall() in your package, and make sure to run the parent::uninstall() method prior to running your custom code. For example, this uninstall() method takes care of removing some custom database tables (since by default any custom database tables found in your package aren't removed when a package is uninstalled.

public function uninstall()
    $db = \Database::connection();
    $db->query('drop table FooBar');
    $db->query('drop table FooBaz');

Note: most packages will not need to implement a custom uninstall() method. Core items of functionality that are installed by a particular package like block types, page themes, attributes and more will automatically be uninstalled during the package uninstallation method.

Adding Custom Options During Uninstallation

The standard Concrete5 package uninstall screen lists all items that will be uninstalled when this package is uninstalled. This is automatic. If you'd like, you can add custom messaging or a form to this list – for example, an eCommerce package might prompt the user to confirm whether they want front-end store content also deleted from their site. To display a custom uninstallation message or form, simply create a file at packages/package_handle/elements/dashboard/uninstall.php. Anything found in this file will automatically be presented to the user after they choose to uninstall the package, but before they actually confirm that they want to uninstall it.

Include a Form

Need to include a form as part of this content? Just add it like you would anywhere, in the HTML, and check the post from within the uninstall() method.

<input type="checkbox" name="removeFrontendContent" value="1" /> Remove front-end pages beneath /store.

Then, from within the controller.php uninstall() method

public function uninstall()
     $pkg = parent:: uninstall();

     $r = \Request::getInstance();
     if ($r->request->get('removeFrontendContent')) {
    // do the deed
