Visiting post-new.php using the back button overwrites an existing post

[jkudish]

1) visit post-new.php
2) write a post
3) publish it
4) click back in your browser
5) write a new post
6) if you save it as draft or publish it, it will overwrite the old post

Reproducable in Firefox, Chrome and Safari.

I can confirm.

I think we should add an admin notice here. The title div gets cleared but the content is still there.

So maybe it would be better to add an AYS (are you sure) if you're trying to navigate away.

I guess it's happening because post-new.php makes an auto-draft and already has a post ID in a hidden input. Not sure an admin notice or an AYS can be added in this situation.

Maybe there is a way to block this and/or force a refresh?

Probably some combination of headers would help, but not sure how universally reliable it is.

We can try using cookies or sessionStorage to detect when a post was published and the back button was pressed, then do window.location.reload(true);.

This also happens in Press This. To reproduce:

1. Go to press this url (e,g. site.domain/wp-admin/press-this.php).
2. Enter some content.
3. Publish. It redirects you to the new post.
4. Click the back button in your browser.
5. Enter some new content.
6. Publish.

The previous post is overwritten.

Adding a query string to the current location (23691.patch) seems to force the browser to reload the page on pressing the back button.

In 33836:

Editor, Press This: force a page reload when the user publishes a post and then clicks the back button.
Fixes #23691.
