Answered Pass a string in URL to snippet

Hi, I need to be able to pass a string in a url to a snippet code call - is this possible in MODx?

So - the url is http://www.example.com/memberbio?23

I want to pass the '23' to the pdoUsers snippet inside the '&users' element as shown below.



Therefore, the pdoUsers snippet will work to display the user with id 23 that is passed via the '23' element in the URL string when the page loads... Looks possible from using the https://rtfm.modx.com/extras/revo/geturlparam getURLParam - but I don't understand the syntax / process.

Any ideas?


Cheers

dubbs.

If I could make a small suggestion -- that will throw an E_NOTICE error if the URL variable isn't set. This one line should do it all.



It will return an empty string (above) or whatever you want (below) if $_GET['c'] isn't set:

<!--?php
return isset($_GET['c'])? $_GET['c'] : '';

<?php
return isset($_GET['c'])? $_GET['c'] : 'c parameter not set';

OK thanks Bob How is the shoulder? Getting better I do hope.

Thanks for asking. It's improving very slowly. I can type now if I rest my wrists on a pad and type slowly (and correct lots of mistakes.)

There's also a getUrlParam snippet that does some basic sanitisation as well: http://modx.com/extras/package/geturlparam
