It does, by default. The get_template_part()
function uses locate_template()
which cascades through the template files in in order of specificity and stylesheetpath/templatepath.
So, if your Child Theme includes a content-inventory.php
, then get_template_part()
will include it; if not, then it will look for content-inventory.php
in the parent Theme. If it doesn’t find it, it will then look for content.php
first in the child, then in the parent.
EDIT:
Taking a stab at understanding what you mean; please clarify if I’m misunderstanding…
You want to include a new template part file within a Parent-Theme template file called content-inventory.php
, right?
The only way, AFAIK, that you can do that is to copy content-inventory.php
into your Child Theme, and then add the new get_template_part()
call where needed.
If a file named content-inventory.php
is included in both the Parent and the Child Theme, then WordPress will always use the Child Theme version, if included using get_template_part()
.
