更新wordpress字段“DATE”

Question

So I have been trying to find a solution for this around 1 hour and I cant find the solution.

how do I update DATE with the update_post_meta() function? I have ACF field which is jquery(date). Ive tried

update_post_meta($post_id,'last_date',$arr[9]);

when $arr[9] is 22/09/2018 like my Date format.

Answer 1

For update_post_meta function it doesn't matter which kind of value you have. It stores it as a string. So the problem can't be related to $arr[9]'s datetime format.

That's why there are only two options to check:

1. Write

   echo $post_id;

before update_post_meta() function and check if it displays correct ID.

1. Again, check your database wp_postmeta table and search for "last_date" field. May be it has some another prefix or postfix.

If to do these 2 steps, you will find the reason by 100%.
