This is my registration table in SQL
http://uploads.aragato-server.net/screenshots/20181127d5d139dfe4.png

This is my query
$this->registrations = EEM_Registration::instance()->get_all(
array(array(
‘STS_ID’ => ‘RAP’, //Registration Approved, Space Reserved
‘OR’ => array( ‘REG_final_price’ => 0,
‘REG_paid’ => array( ‘<‘, ‘REG_final_price*’ ) ) ) ) );

It should return at least 5 datasets based from the SQL data.
However, it returns only the free course, but does not return all the other courses that should be selected. The issue seems to lie within the second part of the OR (All registrations that have REG_paid smaller than REG_final_price).

What am I missing?

After thinking about it, the issue is probably the ‘REG_final_price*’ which is seen by the query as a string and not as the respective column/field.

How do I reference that field?

Also, I have used the EEM_Extra_Meta a bit. For example, I process some registrations and add to each processed regisration an extra meta field ‘processed’ = true.

How can I implement the exta meta into a registration query. For instance, get all registrations where processed is true?

After thinking about it, the issue is probably the ‘REG_final_price*’ which is seen by the query as a string and not as the respective column/field.

That’s correct, and admittedly, the documentation for this is a little hard to find.

Its actually really simple to do, you just need an additional parameter:

$this->registrations = EEM_Registration::instance()->get_all(
	array(
		array(
			'STS_ID' => 'RAP', //Registration Approved, Space Reserved
			'OR' => array( 
				'REG_final_price' => 0,	
				'REG_paid' => array( '<', 'REG_final_price', true )
			)
		)
	) 
);

array( '<', 'REG_final_price', true ) tells the model that the value passed is a field name.

How can I implement the exta meta into a registration query. For instance, get all registrations where processed is true?

Same as with most models, you add the model and field, so something like this:

'Extra_Meta.EXM_key' => 'processed',
'Extra_Meta.EXM_value' => true

Meaning your code ends up like this:

$this->registrations = EEM_Registration::instance()->get_all(
	array(
		array(
			'STS_ID' => 'RAP', //Registration Approved, Space Reserved
			'OR' => array( 
				'REG_final_price' => 0,	
				'REG_paid' => array( '<', 'REG_final_price', true )
			),
			'Extra_Meta.EXM_key' => 'processed',
			'Extra_Meta.EXM_value' => true
		)
	) 
);
