i've created an extension plugin and i'am having issue to redirect on the trigger onExtensionBeforeInstall

Here is my code :

class plgExtensionExample extends JPlugin{

    function onExtensionBeforeInstall($method, $type, $manifest, $eid){
        $app = JFactory::getApplication();

When i try to install a plugin a have a javascript error :

In chrome

Uncaught TypeError: Cannot read property 'redirect' of undefined

In firefox

TypeError: res.data is undefined

I've searched in joomla and res is the result of a call in ajax, but res need to be an object and it's a string of html. I've tried to reach the url which is called in ajax but i got this message :

The most recent request was denied because it contained an invalid security token. Please refresh the page and try again.

Thanks for your answers.

  • Why are you trying to redirect to the base URL before an extension is installed?

  • I want to do a check before installing a plugin, and in some cases i don't want to install the plugin Aug 1 '17 at 8:58
  • Is this check for your own plugin, or other plugins being installed on your site?

Try removing this line;

  • I've already tried and I got the same error. It's the same when I try to exit or die() Aug 2 '17 at 7:27
