[Vtigercrm-developers] How to delete/uninstall a module

[Hamono, Chris (DPC)]

There is often a need to uninstall a module, community vtiger (6.2) does not have a built in way to do this.

There is some code here...
https://discussions.vtiger.com/index.php?p=/discussion/28895/how-to-uninstall-one-module/p1

I thought I'd improve on the code a little bit and include it here for others with the need

Please remember to delete the file after uninstalling the module it is definitely a security risk!!!
An additional test would be to ensure only a logged in admin could run this file but as the need is so low I didn't think it was worth the extra effort

Call it like thus...

Mydomain.moc/vtigerfolder/deletemodule.php?modulename=MyRss

if (!function_exists('vtlib_isModuleActive') || !class_exists('Vtiger_Module')) {
    die("Unable to process request; unmet needs");

// get the name from the commandline
$modulename = (!empty($_GET['modulename'])) ? $_GET['modulename'] : null;

    die("modulename {$modulename} not valid");
}


// load the module
$module = Vtiger_Module::getInstance($modulename);

if ($module) {

// check if the module is active if so it cant be deleted
    if (vtlib_isModuleActive($modulename)) {
        die("You cannot delete an active module");
    }
    echo "Module {$modulename} is about to be deleted<br/>\n";

// Delete from system
    $module->delete();
    echo "Module {$modulename} deleted!<br/>\n";
    echo "Please manually delete the source files for {$modulename}, Do not forget layout files, language files and other possible files";
} else {
    echo "Module {$modulename} was not found and could not be deleted!";
}
