a simple problem about cookie(PHP)

naihe2010 · 03-13-2006, 07:51 AM

I know, the "setcookie()" must be front of every action in PHP.
But, I know lots of web is comparing the user and pass with the database record first and "setcookie()" as follow.

How to do this?

Hi

SetCookie must be used before any output the script makes, not before every action.

So it's really not that hard.

You must handle your cookies before anything is output to browser (including PHP error/notice messages)... before the headers are sent out. One way to ensure this is to use output buffering:

Code:

ob_start();

// whatever your code is to check db and information, 
// validation, etc.  Just dont' do anything that outputs 
// anything just yet
   
setcookie(); // whatever

// now you can output 

ob_flush(); // flush buffer
