Hi,

I am looking for a function to update a boolean field “fl_flag” to “True” for all posts in my custom post type “events”.

I couldn’t find an effective solution anywhere. Any help would be much appreciated.

thanks,
Andrew

The following code can be placed at the bottom of your functions.php document. It will loop through all your posts within that post type and set fl_flag to 1/true. You can delete it after viewing any page once. If the field fl_flag does not exist in the post it will create the field.

$args=array(
	'posts_per_page' => -1,
	'post_type' => 'events'
);
$the_query = new WP_Query( $args );
if ( $the_query->have_posts() ) :
	while ( $the_query->have_posts() ) : $the_query->the_post();
		update_field('fl_flag', '1', get_the_ID());
	endwhile;
endif;

ok thank you, will give this a try, although I need to figure out how to run this code once per day… Would it bog down my site too much you think?

many thanks again,
Andrew

Speed depends completely on the number of posts and speed of your server. As for scheduling you can look at the following link for a WordPress Scheduled Event. You can set this so it runs the first time someone visits the site each day. The other option would be to create a cron job but I will let you look that up if you need it.
