Introducing 'sanitize_post' filter

[enrico.sorcinelli]

I was trying to do a post field sanitization on new post insertions that depended on the value of another field.

While it quite easy in administration context, using for example pre_{$field} or {$field_no_prefix}_save_pre filters in conjunction to $_POST and so on, it seems that there's no direct way using wp_insert_post since the filters above do not have references to the other fields or to the ID of the post (which is also useless in the case of new posts) but only refers to the value to be sanitized.

So this enhancement aims to introduce new sanitize_post filter.

PS: Of course I could sanitize values directly in wp_insert_post but only assuming I have control of the code or at the cost of duplicate the sanitization in each wp_insert_post calls.

I just updated the patch by moving the filter at the end of sanitize_post() function.

Missed the 5.2 Beta 1 deadline, moving to 5.3.

Replying to enrico.sorcinelli:

What about using the ​wp_insert_post_data filter for that? Just want to make sure I understand the use case.

@enricosorcinelli To answer @SergeyBiryukov's question, does the wp_insert_post_data filter work for your situation?

[SergeyBiryukov]

I talked to @enrico.sorcinelli at WordCamp Torino. IIRC, wp_insert_post_data should do the job here.

The consensus was that #21676 is more important, any efforts are better spent there.

Closing as maybelater, feel free to reopen if still relevant.
