Using WordPress ‘post_form_autocomplete_off()’ PHP function

The post_form_autocomplete_off() WordPress PHP function disables autocomplete on the ‘post’ form (Add/Edit Post screens) for WebKit browsers, as they disregard the autocomplete setting on the editor textarea. This can break the editor when the user navigates to it with the browser’s Back button. See #28037.

Usage

post_form_autocomplete_off();

Parameters

None

This function has been replaced with wp_page_reload_on_back_button_js() that also fixes this problem.
