wp_insert_post() should accept a meta_input argument

[johnbillion]

wp_insert_post() accepts a tax_input argument to set the post's terms, but there's no similar argument to set the post's meta fields. add_post_meta() must be called for each meta field after wp_insert_post() is called.

I'll do up a patch at some point.

Basic fix that loops through provided meta fields and values

Provided patch proves that it can be done really easy. This patch does not check for capabilities and there is lots of room for improvement. Just showing how easy it can be.

Now on to if it should be done and what we need to consider before doing so.

Surprised this isn't implemented, especially with the meta field initiative going on.

20451.2.diff​ is an updated patch that also updates the docblock for wp_insert_post and includes a unit test for the newly added meta_input parameter.

ok - devs need to use register_meta() to sanitize these values

[wonderboymusic]

In 33910:

Allow wp_insert_post() to accept a meta_input argument. Devs should use register_meta() to ensure that specific values specified by key are sanitized properly.

Adds unit test.

Props CoenJacobs, swissspidy.
Fixes #20451.
