可以在PHP重定向中发布数据吗？

Question

Well right now I have a page (page2.php) and at the top it does some validation checking and if something fails it bounces back to page1.php. The problem is that page1.php is loaded by a post meaning it is the end result of a form. This means that all the post data I originally have on page1.php is lost.

So here is my code:

if ($validation_fails)
{
    header('Location:page1.php');
}

Answer 1

You can post data back with cURL or re-structure to do the validation at the top of page1.php and if it doesn't fail, take to page2.php. If you are doing some sort of multi-step form, you could save all the data in a session and populate fields if there's matching data in the session. Not sure if that applies, though.
