setcookie($cookie_name); /* This header-line would not be sent if above red code is set ! Do not get frightened by the following comments , what you really need is : Copy & Paste & Customize with care the php code
you will take your time later to get deeper into the details, so you may well skip them, if you are new to PHP Here the cookie set at the beginning of this script is cancelled ( up-dated to the value="" )
For to cancel a cookie in PHP, is enough to call the php-function setcookie(); like it is here, by passing as argument only its name and no value. Now, as the member is not logged, let's cancel the cookie because if the access data are not correct or there is no access data, the cookie would be set anyway and by pasting the address of any member page, after the login page has been unsuccessfully loaded, the reserved page would be returned thanks the cookie : member=logged ( see the layout of any_reserved_member_page.php ...you first have to be demo-logged ) . But you would say the cookie is set at the beginning of the page , how it comes that here is considered unset as this conditional expression switches in ? ( well the cookie is not set, but is going to be set by loading this page into the Client machine ) Cookie is a PHP header in php language , and when this page was requested to the server, the headers for that page were already sent , and there was no such a pre-existing cookie on the Client machine, this is going to be set now ( on this loading ) , so it comes that the value of member is : "logged" at this point while unsuccessful login and so, by calling the php-function setcookie(), just the sole cookie name... the value : "" is re-assigned. ( ...see another example @ The cookie value ="logged" connot be monitored before the updating function : setcookie($cookie_name); as this would generate a php error wherein the php-parser claims to not be able to send the actual up-dating header setcookie($cookie_name);
Infact we should set an echo instruction before setcookie($cookie_name); to be able to read the cookie that is going to be set :setcookie($cookie_name, $cookie_value); ...this would generate an output , as the headers must be set before any output ... so the error is generated.
We can anyway, for testing purposes, bear the error and set the monitoring code : echo"<br>$cookie_value<br>"; to get the error and the value : "logged" ( --- we really do not need such an obvious test, but there is no other way, and of course the complete cookie , implemented at the beginning of this page, would be set and active, after the interruption of sending the updating-header : setcookie($cookie_name); ...if we now link to any member page we can get it, although we have not set any access data --- ) */mysql_close($connessione); }
