How do I get fields to display in an article via php?

So I am creating a new fields for an article. I want those new fields to display in that article via php (I am using the NoNumbers Sourcer for that).
So if I had a "All about BLUE Widgets" article with fields called "size" and "weight".
I want "size" and "weight" to be displayed in the body of the "All about BLUE Widgets" article.
And I would want the "size" and "weight" of the RED Widget to display in the article on "All about RED Widgets"

Does that make sense? Is there a Flexi Content plugin that will do this without php?
Is the php something like this???:
<?php
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query
->select('size')
->from('#__cck_store_widgets_specs')
$db->setQuery($query);
$widgetSize = $db->loadObjectList();
echo $widgetSize->get("size");
?>
Any help would be great.
Thanks

you can use sql query in select field, not good for you ?

Not sure what you mean. How would you write the php differently?

not but you can use many field with sql query and put result in value
