Hi Calpaq, how do you save posts? I mean do you run a code to save posts or use Meta Box plugins?

If you need to hook after Meta Box save post data, you can just use 'rwmb_after_save_post' hook, or save_post (with priority > 10). And then use update_post_meta to update meta data to an existing post of your choice.

Hi Tran,
Thanks for replying,
This is all relaated with wordpress admin
Let me tell you that I am not using any custom code to save posts and use meta box plugins. In my case I am using custom post type, so I have registered post type and by default its menu is added to wp admin so from there adding/updating/deleting posts. WordPress doesn't validate for post title and it can add same title with different Id. What I want is to validate post title ( i.e. check if post exists and if found retrieve that post and update that instead of creating new post with again same title ). I am using some metabox fields for this post type and now I want to check before insert that if any post exist. So actually I do not want create/insert any new post (if exist ), retrieve the ID and save these meta fields to that existing post, Can you help me in saving these fields with existing post when its already there.
Thanks & Regards

I got it. I think the hard part in this situation is detect if there's any existing post with the same title. I'm afraid I don't have any that code available.

Once you get that post (with post ID), you can use update_post_meta function to manually update fields.

I am researching this topic and have a use case where I have a datetime field.
I would like to update an existing post with a new date.
I would like to use the jQuery datetime UI for the user to select the date.

So, there is an existing post with an date/time set. I want the user to update the field using the date time picker. Right now, the front end form only created new post it does not have the ability to update post meta I don't think.

I can easily update post meta using the Meta Box functions to update, but i want to bring in the date/time picker.

Any solution for this use case?

thank you!
