access to (some) web pages without logging in

Submitted by arwed on Sun, 02/02/2014 - 14:25

Hi, I wanted to allow at least accessing some specific read only pages (like the myelectric example) for users without need to login. Is there a place where I could e.g. simply add the readonly apikey just in the code to allow that?

Currently I only see the page -- but not showing the values ... ;--(

Thanks for your help!

try adding ?apikey= to the URL with your api key that may work, if it doesnt I will need to update a few things in the module to make it work.

Hm, I tried it with the read only apikey directly in the URL of the browser. No change in display except that I now saw appearing the Extras menu (but with no item to select below).

What I would find great is if one could add the apikey to one of the files to keep the apikey a bit hidden. Do you think that is possible? In that case I could enable a fiew pages only for "public" access.

Yet another question related to that: in the packetgen's file "setpoint.php" there is some PHP code like

<?php global $path;

  if (!isset($_GET['apikey'])) $apikey = ""; else $apikey = $_GET['apikey'];

?>

So if apikey is _not_ set we set it to an empty string, otherwise to the apikey value? That's not really clear to me; ok, I'm new with PHP and quite new with webpages, but I would like to understand that ...

For test purposes I tried to echo the apikey variable and it's empty even after this line. I also tried to show the value from the script area of the file and there apikey is empty as well. Does anyone have some helping hints for me here?

Thanks a lot!

emoncms isn't the easiest place to start learning php as it gets quite complicated.
$_GET['apikey'] looks at the string passed via the URL (after the ?) and see if it includes a key called apikey.
if it doesn't exist the variable $apikey within the php page gets set to an empty string, as the value hasn't been passed to the page via the URL.
If the URL does include a key called apikey the variable gets set to whatever value was passed associated with the key apikey.
