It is possible, using the date_query
argument. By default this uses the publication date, but you can tell it to use the modified date by using the column
argument. So if you wanted to query all posts modified after June 30th 2019, you’d use:
'date_query' => [
'column' => 'post_modified',
'after' => [
'year' => 2019,
'month' => 6,
'day' => 30,
],
],
The column
parameter of WP_Date_Query
supports:
post_date
(default)post_date_gmt
post_modified
post_modified_gmt
comment_date
comment_date_gmt
A WP shell example for the date query in WP_Query
with post_modified_gmt
and the after
parameter:
wp> echo ( new WP_Query( [ 'date_query' => [ [ 'column' => 'post_modified_gmt',
'after' => '2 days ago' ] ] ] ) )->request;
will output:
SELECT SQL_CALC_FOUND_ROWS wp_posts.ID FROM tfl_posts WHERE 1=1 AND (
wp_posts.post_modified_gmt > '2019-11-16 10:00:27'
