Selection of goods by Bitrix property?

Question

PHP

Hello! For an online store, in the product card, you need to organize a block in which products with the label "new" and "sale" will be displayed.
I did it through the catalog.section component. All goods are displayed. Display of all properties of goods in the settings set. I write the first two lines: I create a new array for the filter by the "NEWPRODUCT" property.
As he no longer shamanized and wrote this way and that - emptiness. Doesn't display items tagged new.
What can be a jamb?
Thank you.

Answer 1

What if you do that?
$arrFilternovelty = Array('!PROPERTY_NEWPRODUCT' => false);
NEWPRODUCT is of type "List"?
If you write PROPERTY_NEWPRODUCT_VALUE in the filter, then you need to compare it with the value of the list property, for example:
$arrFilternovelty = Array('PROPERTY_NEWPRODUCT_VALUE' => 'Yes');
or so, if the property value "Yes" has XML_ID 'Y':
$arrFilternovelty = Array('PROPERTY_NEWPRODUCT_VALUE_XML_ID' => 'Y');

Answer 2

What type of property does your NEWPRODUCT have?
