Cookie and include

[daok]

Hi,

I have 2 servers both doesn't react the same way.. well that aren't that important (they are both on PHP 4.x).

The problem is that 1 let me INCLUDE a file and SET a cookie and the second one doesn't let me SET a cookie because of the include.

The include file doesn't echo any value.

Here is the error I got :

//This is my error :

Warning: Cannot add header information - headers already sent by (output started ............

Here is my code:

<?php
require_once("inc.php");
if (isset($_COOKIE["test"]))
{
	setcookie("test","",time()-3600);
	echo($_COOKIE["test"]);
}//Fin du if
else
{
	setcookie("test","voici mon test");
	echo("je ne vois pas de cookie");
}//Fin du else
?>

All the stuff in inc.php are in comment so why do I still get that error and I really need the include file for my project.

Thank you

hi,
u cut the "output started ............" part of the error message. U should indeed check on which line the error occurs. In general, your script is outputting somethin else BEFORE settin the cookie - can be every echo-command or even whitespace at the begginning of your file - make sure <?php is really the first text in your script and do not output nothing before havin set the cookie.

Warning: Cannot add header information - headers already sent by (output started at /home/virtual/site37/fst/home/pdesjardins/public_html/hitches/www/inc.php:224) in /home/virtual/site37/fst/home/pdesjardins/public_html/hitches/www/test2.php on line 10

That doesn't help me much cause line 224 is the last line : "?>"

and yes "<?php" is the first thing on the line 🙁

What's wrong? 🙁

[Natty_Dreadlock]

ok, i believe i see the problem - u say line 224 only contains ?> - but i guess there are a few spaces or \n after the ?> u do not see in your editor. so open inc.php, make whitespaces visible (there should be some option), move your cursor to the end of ?>and press DEL a few times to make sure really nothin is following the ?> - should solve the problem.

i am in dreaweaver and I can clearly see that I am really on the last time 😕 I have done few delete and nothing changed 🙁

On my server (my localhost) everything is fine. WHen I shoot the file with FTP to the real server, I got this problem 😕

[Natty_Dreadlock]

ok, did u transfer the php file as ascii or binary?

[daok]

I use LeechFTP. The transfert was on automatic. But this morning I tryed with Binary transfert and Text transfert and both got the same problem.:queasy:

[Natty_Dreadlock]

and both inc.php and test2.php are exactly the same files on your server and your local server???

[daok]

Amazing...

This morning I decided to copy and paste all the code in INC.php to an other file. I deleted the original INC.php and renamed the new "copy" file to INC.asp.

Now I go to the server and it works! I was very happy BUT that was just an exemple because what I have to do is to save not a variable but a class (object).

With my server I serialize and unserialize and everything is fine. On the real server I still got an error:

Fatal error: Call to a member function on a non-object in /home/virtual/site37/fst/home/pdesjardins/public_html/hitches/www/index.php on line 69

non-object? humm very weird because here is the code :

require_once("inc.php");
$b = new hitch_basket();

if(isset($_COOKIE["basket"]))
	echo("I see the cookie!<br>");



$b = unserialize($_COOKIE["basket"]);
if (is_object($b))
	echo("I see an objet <br>");
else
	echo("NO OBJECT!!!<br>");
if ($b->Length() == 0)//Si vide
{

//...
}

Here is the output:

I see the cookie!
NO OBJECT!!!

Fatal error: Call to a member function on a non-object in /home/virtual/site37/fst/home/pdesjardins/public_html/hitches/www/test2.php on line 18

line 18 = if ($b->Length() == 0)

I don't understand, the cookie is really there and he is not empty but I can't unserialize it on the real server
😕

hi,
so it seems the first problem was caused by some encoding or whitespace issue. Concerning your second question, u should first try to remove $b = new hitch_basket() coz it's not necessary and might be a reason for your problem. Secondly, echo the content of the cookie and see whether it's valid or not. The docu at http://de2.php.net/manual/en/language.oop.serialization.php can give u other ideas what's wrong.
hth and if this does not solve your problem feel free to ask again.

I have read the help but I can save in a session without problem. The problem I got is only with Cookie :queasy:

Here is the complete code of my "example" that doesn't work.

<?php
require_once("inc.php");
if(isset($_COOKIE["basket"]))
{
	echo("I see the cookie!<br>");

$b = unserialize($_COOKIE["basket"]);
if (is_object($b))
{
	echo("I see an objet <br>");
	$b->Afficher();
	$b->Clear();
}//Fin du if
else
	echo("I see a cookie but NO OBJECT");
}//Fin du if
else
{
	$b = new hitch_basket();
	$b->Ajouter("20-101",0,1);

setcookie("basket",serialize($b),time()+3600*24);//24h
echo("Enregistrer dans le cookie");
}//Fin du else
?>

Here is what I got a the web Server :

I see the cookie!
I see a cookie but NO OBJECT

Here is what I got on my localhost server :

I see the cookie!
I see an objet 
Id : 20-101, Table : 0, Qte : 1

I have open both cookie (web server and my localhost) and they look quite the same (except the url)...

So I guess that the way it saves the stuff is alright and the way it try to restore the data isn't alright :\

I need that to work, I will try to do a run with it, thx to help me bro, we should be near of the solution.

I just did a little example, that way you will be able to test it from your server. This example works from my server but not form the web server.

Create 1 file called student.php

<?php
class student
{
	var $strName;

function student()
{
	 $this->strName = "Unknown";
}
function GetName()
{
	return $this->strName;
}
function SetName($strNewName)
{
	$this->strName = $strNewName;
}
function Show()
{
	echo("<br>Student name is : " . $this->strName);
}
}
?>

and 1 file : test_student.php

<?php
require_once("student.php");//This is the class

if(isset($_COOKIE["STUDENT"]))//If the cookie exist, we load the inforrmation from it
{
	$b = unserialize($_COOKIE["STUDENT"]);//Get the student information from the cookie
	setcookie("STUDENT",serialize($b),time()-3600);//Kill the cookie to be able to redo the test just by pressing F5
	echo("From cookie:");
	$b->Show();//Show the name

}//Fin du if
else
{
	$b = new student();//Create a new student
	$b->SetName("Patrick" . rand(0,1));//With Patrick and a number between 0 and 1
	setcookie("STUDENT",serialize($b),time()+3600*24);//Store the information for 24 hours
	echo("From new instance:");
	$b->Show();//Show the new student
}//Fin du else
?>

Local host : all is fine
Web server : Fatal error: Call to a member function on a non-object in /home/virtual/site37/fst/home/pdesjardins/public_html/hitches/www/test_student.php on line 9

[Natty_Dreadlock]

ok i'll test it gimme a few hours 😉.

[Natty_Dreadlock]

ok i think i solved your problem check out this code:

<?php
require_once("student.php");//This is the class

if(isset($_COOKIE["STUDENT"]))//If the cookie exist, we load the inforrmation from it
{
    if(get_magic_quotes_gpc())
        $obj = stripslashes($_COOKIE["STUDENT"]);
    else
        $obj = $_COOKIE["STUDENT"];

$b = unserialize($obj);//Get the student information from the cookie
setcookie("STUDENT",serialize($b),time()-3600);//Kill the cookie to be able to redo the test just by pressing F5
echo("From cookie:");
$b->Show();//Show the name

}//Fin du if
else
{
    $b = new student();//Create a new student
    $b->SetName("Patrick" . rand(0,1));//With Patrick and a number between 0 and 1
    setcookie("STUDENT",serialize($b),time()+3600*24);//Store the information for 24 hours
    echo("From new instance:");
    $b->Show();//Show the new student
}//Fin du else
?>

student.php was not changed at all - the problem is kinda simple, and i experienced it before so it took me less time than i expected so find a solution: On my machine, your code di not work, but i found out that my machine and probably your server have magic_quotes enabled, while your local machine does not. therefore, i added a check for magic_quotes which strips backslashes which confuse the unserialize function so it just returns false. Now, it should work both on your server and on your machine.
