I know how to make custom fields for my custom post types. I also know there is the Advanced Custom Fieldsplugin.

But I need to know how I can store my custom fields in my custom post type to my custom DB tables. I've been looking for tutorials, but I only find how to create SQL tables in plugins.

How can I fetch "my data" (and save it in my own tables) and at the same time save the other data for the page the normal way?

  • When you cay "fecth my data", you refer to the data in your custom table of the data in the custom field? – Tomás Cot Sep 8 '14 at 13:53
  • I mean the data that is entered into custom fields and submitted when I click the "save new post" button. I just want to store the data in my custom fields into my custom tables. – Steven Sep 8 '14 at 14:52

Steven, I think you are looking for the save_post action, you should create the function you want to use and use the add_action function.

You can find the data from the custom fields in the $_POST array.

You don't have to worry about the "other content", at least if with that you are referring to the title, content, categories.

Here is a great post by Austin Ginder: https://anchor.host/acf-custom-fields-stored-in-custom-table/.

I've also come up with a free plugin: https://wordpress.org/plugins/acf-fields-in-custom-table/
