Reply To: How to update the db with a default value

In most cases it would be much easier to alter the code in your template to check for a value an if it does not exist then show the default.

$value = get_field('my_field');
if ($value === false) {
    $value = 'default_value';
}

To do it the other way, you can:

• create a temporary function that runs on a WP hook
• Do a query that gets all the posts in the post type you want to update
• Loop through all the posts and check the field
• If the field is empty, update the field with the default value

I generally do the former and code my templates to deal with default values because I assume that any field might be empty.
