How to check if a module is installed?

[arjen]

I've made a simple module called MarkupBox which is not installed in the CMS, but the files are in the module directory (/site/modules/). When I call the module from a template it returns the value. I suppose there is a way to check if a module is installed, but I can't find it in the code or in the forums. I'm looking for someting like:

if ($modules->get("MarkupBox")->isInstalled())
{
    // Do something
}

Module:

public function render()
{
    $out = "Test";
    return $out;
}

Template:

$box = $modules->get("MarkupBox");
echo $box->render();

Thanks!

You're very close actually . This is how it works:

if($modules->isInstalled("MarkupBox")) {
    // do something
}

It's the other way around Thanks nik!

Actually $modules->get("MarkupBox") will install the module if it's not

Thanks soma for the info. I ran into some issues but realised the module installed itself. My new code:

if ($modules->isInstalled("MarkupBox")) {
    echo $modules->get("MarkupBox")->render();
}
