There results of hooks

I have a slim.before hook that needs to store some data about the request so that the function that gets called by the route can see it later.

I thought "env" would work, but apparently you can only change environment in Middleware. I think I get that this is because env is about Rack and Middleware and I need to do something inside the slim app. So the question is where can I put stuff so I can access it later on down the process?

    answering myself perhaps...

    would config be the right place to store some thing like that?

    $app->config("user", $user );

    What about storing it in $_SESSION?

    With hooks I have noticed anomalies with version differences:

    // PHP > 5.3

    $app->hook('slim.before.router', function () {});

    should be equal with:

    // PHP < 5.3

    $app->hook('slim.before.router', 'hook_before_router');

    function hook_before_fouter() {}

    The latter is however never executed. Forced me to "hook" by explicitly locate code in the execution path instead.

    @Todd Geist the config is used to store the app settings, it would probably work but you could accidentally overwrite the settings or the app itself could overwrite your data.

    Anyway, you can use global variables to store your data or you can create a class with some setters and getters to set and retrieve the data. Storing it in the $_SESSION is also an option if you want it to persist between page loads as Daniel already pointed out.

    @Daniel Lillqvist what version are you using? I'm not having any issue with the hooks using the master branch.

    @Garnier I did this test on both releases. Shouldn't the test output both on a PHP > 5.3 or is there some branching going on depending on the PHP version under the Slim hood?

    My home machine is PHP > 5.3 and production server PHP < 5.3. The production server did not hook at all.

    The function name is misspelled like hook_before_fouter instead of hook_before_router, also for PHP < 5.3 you'll need to remove or comment the > 5.3 hook as anonymous functions are not supported and you'll get a parse error.

    A part from that it should work just fine.

    @Garnier I feel like, Doh! :) Anomalies.. yeah right! Confirming that It does work just as it is supposed to! This time not even a proper IDE would have helped me. Thanks for pointing out my blindness!
