CB auto action: display fields outside of joomla

Hello

We would like to display CB html fields with an auto action but outside of joomla in an iOS App.

How and what auto action could we use for this ?
The user is authenticated by joomla within the web view and has full access to all joomla data, but we have a native page on which we would like to display some CB fields (either raw or best with ajax edition possible)

Thanks for your idea

Only way to interface native with Joomla in general is using API endpoints, which don't exist in Joomla. You can basically fake it with CB Auto Actions by calling a auto action URL from your native API. This will initialize and route through Joomla so you should have access to all of Joomla and CBs API. The problem will be the user object. It won't have a clue what user object you're trying to use so it'll just be a guest user object unless you include the user id in your request. Example as follows would execute an auto action (it must have Triggers set to None) with a specific user.

index.php?option=com_comprofiler&view=pluginclass&plugin=cbautoactions&action=action&actions=ACTION_ID&users=USER_ID

I'd recommend using a Code action with Method set to PHP then responding with a small JSON payload then convert that JSON into whatever display you're wanting in your native application. It's possible to just respond with HTML, but that kind of defeats the point of using a native application to reduce data load.

Thanks ! That's why we rely on CB, for its power

What would you suggest for php code if we want to retrieve the user fields in json format ?

You should be able to just use substitutions in your PHP. Example as follows.

Action
Method: PHP
Code: Output
Display: exit

Be sure to add &format=json or &format=raw to your auto action URL so all it outputs is the JSON data. Will review adding a new output display parameter for JSON so it can goahead and set the header for you too.

I have two more questions.

Say that I have
with [cb_marketevents] being a GJ event id.
Can I get directly the corresponding GJ event title in the above json without going with a SQL request as it's CB part and how ?

For other joomla components, if I want to use CB API and auto actions to get DB table values, I guess that I have to go through a mySQL standard request in the PHP code ? or can I use the query auto actions to output something also in raw or json format ?

Ok, latest build available now has just made this even easier. Once installed you'll be able to do the below for example.

Action
Method: PHP
Code: Output
Display: JSON

This would give you a JSON dump of the raw user object. The code action can now handle returning objects and arrays. They'll always be serialized to JSON during layout handling. Using my earlier example you'd have the below.

Action
Method: PHP
Code: Output
Display: JSON

You don't need to json encode manually and this output usage sets the header content type to JSON for you. I recommend the above approach so you only return the information you actually need instead of the entire user object.
