Before Process

The Before Process is the first code event. It runs before anything is processed for a screen.

This is a server-side ProcScript event.

Please note that there is no item data available at this point.

Available Variables

The following variables are exposed here:

• translations - {"Title":"Heading", etc}

• location - current URL, eg "https://procdu.com/mcapp/id/screen" - change to redirect

• url_parameters - array of passed URL parameters, eg ?id=123 ⇒ {”id”:123}

• my_variables - Array of keys and values - these are yours to change

• custom_tokens - Array of keys and values you can use later in markdown or defaults (eg custom_tokens.foo = "bar" - then use @[pf_custom:foo]

• is_logged_in - true/false

• auth_item - Raw item used in authentication or null (eg: {item_id:1234, fields:[...], etc})

• auth_item_values - Simplified authenticated user item or null (eg: {title:"foo", number:2, etc})

Examples

Let’s say you want to change the Save button to say Commit instead:

translations["Save"] = "Commit"

You have a “role” field on your user record and want to make sure only managers can access this screen:

if ( auth_item_values["role"] != "manager" ) {
	throw "Not authorized"
}

Maybe you want to save a field from the authenticated user record for use in a field default value as a markdown token:

custom_tokens.role = auth_item_values.role
// use as @[pf_custom:role] in field default

As always, use-cases are endless. Just remember you have no item data at this point.
