The session in PHP cannot be transferred across pages? A cross page is lost. it is blank!

The session in PHP cannot be transferred across pages? A cross page is lost. it is blank! This post was last edited by MoreQuestion at 07:57:23

For example, first browse the. php file and write a session value in it.

Then browse B. php to get the session value written by a. php. Empty!

Why? The test is normal on the local machine. The upload server is complete.

Session information of PHPINFO

Session. save_path D:/hosting/user/html/temp

This folder is readable and writable.

When you browse the. php page, a large file is generated and the session value is saved.
When you browse the B. php page, a file of 0 size is generated. Not available? Why?

A. php

 
 session set
 

The file is normal and the session value can be printed.

B. php

 
 session get
 

Nothing.

Reply to discussion (solution)

Var_dump ($ _ SESSION ['session _ value']);

Is that the same on your server?
Session. save_path D:/hosting/user/html/temp

You may find the directory locally. Is there a directory on your server?

It indicates that the above code is correct. you can test it locally. the server is not tested yet. you can consider the suggestions on the second floor.

Is there a cross-domain relationship between a and B?

On the server, I set this to a omnipotent folder, which can write everything.

Var_dump ($ _ SESSION ['session _ value']);

No, no value ......

Why? The server is IIS. But it is impossible. in this way, the local environment is virtualized to test, but it still looks like this, and it hurts me.

I can display the values after session_id (1) on both pages, but this will not work for multiple users.

Browser problems?

What are the browser problems?

I use IE6 to IE9 ...... Not changed.

Session_id (SID );
Session_start ();

Session_id (SID );
Session_start ();

Is SID a constant?

Have you solved this problem? I just encountered this problem today, but I still failed to solve it after a day!

I hate the php session.
