filter results and forms using Joomla ID

[piston]

My site will be based on Joomla so I need way to filter all forms results using the Joomla ID. I added a column in my table called "User_id" which should match the logged in user's Joomla ID. I can do this in my manual forms by adding this php snippet:

<?php $user = JFactory::getUser(); echo $user->id; ?>

This will insert the user's Joomla ID into the form (usually hidden). I can't get this to work in Caspio.

How do you enter in a php snippet as default for a text field or otherwise? (like to filter results according to user ID?)

Wouldn't it just be something simple like

<?php $user = JFactory::getID(); echo $user->id; ?>

should be but I was told by Caspio that you cannot use php to enter values into form elements.

In order to be able to receive a parameter in the Caspio form which is passed from an external source, the parameter should be passed in the URL, you can then receive it by calling it in the format: [@parametername]

Your URL:

www.yourdomain.com/page.htm?parametername=value

sure but then you could easily fake your user_id and get into other people's databases
