Getting Information from POST data I am trying to create a plugin that takes the POST data from an order and emails it to the end user. Which property should I use to do this? I've already tried to use getContent() and getContentFromPost().

So for example if I have 

         &lt;input type="text" name="dataName" value=""&gt;


And in my plugin I'm trying to get the value of "dataName" which property should I use?
HttpRequestService's getPost is what you're looking for:

$value = craft()-&gt;request-&gt;getPost('dataName');
