(Sorry for my poor english)
I'm writing a plugin which performs a few checks when a new post is saved by the user. Everything works fine using two hooks : wp_insert_post_data and save_post. I can perform my checks and store the results.
After that (after the post is saved), I would like to display a message to the user, depending on the result of the check.
I think I understood that admin messages are handled through GET variables by wp-admin/post.php which I can't edit.
Is there any way for me to hook myself this redirect_post() function, or another way to display messages in the admin section ?
Thank you for your help.
