I'd like to change the title field of a post in admin panel. I'd like this field was "textarea" instead of being "input type='text'".
Would it be possible through any hook in functions.php?
Thanks in advance!
as this is a default field, i don't think it is possible to achieve what you want with the help function hooks, however you can do this by editing edit-form-advanced.php file inside wp-admin folder,
the code you may want to edit is located in line # 291,
this is the input type for title field
Do this at your own risk as you are going to edit wordpress core file, once you edit this you might not able to update your wordpress automatically
