使用PHP登录后，如何将用户重定向到他们的上一页？

Question

I have a log in widget included on every page on my website. Currently when they log in, they are redirected to the home page. However I want it so when they log in, they stay on the page they are currently viewing.

On my forum you have to be logged in to post (obviously). I would like it so they will stay on the forum post they are trying to reply to after logging in, rather than having to find it again. How do I do this?

Answer 1

The simplest (albeit not completely reliable way is to use HTTP_REFERER and redirect to the referer page. You might need to pass this around a bit in case your login action spans multiple page.

The more proper way is to set the current (unlogged) page in session and redirect to that session value page on login.

Answer 2

It depends on the case but a couple options come to mind;

• Having a redirect parameter that will redirect the user once he logs in.
• Using the HTTP_REFERER to refer the user back to where he came from.
• Depending on the login form; you could send an ajax request to login the user without moving him

But I think it ultimately depends on your environment and since you haven't provided any information/code other than my forum I can only be as vague as your question.

Answer 3

You can bind your current page inside your login widget inside a hidden field and tell the authentication page to redirect to this binded value as a page after login success .

Or if you want to be more secure try using sessions and bing the current page inside it then extract the variable binded into this session in your authentication page then redirect to it as a valid page

and you can also check this variable if is a valid page by using file_exists so plz try that and tell me the result
