help with setcookie function

knowram · November 10, 2006

I have three pages. The first has a form on it with a text field. That gets submitted to the second page where I would like to set that submitted text as a cookie so that I can access that info on the third and following pages.

If I do this where I set the variable on the same page as i use setcookie everything works fine
[code]
//Page 1
<?php
$drname = "jacob";
setcookie("TestCookie", $drname);
?>
//Page 2
<?php
echo $_COOKIE["TestCookie"];
?>
[/code]

but if i do this it will not work
[code]
//Page 1

<form>
<input type="text" name="drname" size="24" />
<input type="submit" name="Submit" value="Submit" />
</form>

//Page 2
setcookie("drname", $drname);

//Page 3
echo $_COOKIE["drname"];
[/code]

What am I missing
Thanks for the help in advance.

hi, i just wanna ask if did you set your cookie in page 1? maybe thats the error coz you retrieved your cookie in page 2 without setting it in page 1..

More power...Good Luck!!!

On page 2, instead of using $drname, use $_REQUEST['drname'], as $drname will only be set if register_globals is set to on, which it is not in your case due to your problem. Simply make page 2 be this:
[code]
setcookie("drname", $_REQUEST['drname']);
[/code]

That looked like it would work however it still dose not seem to.
Any other ideas?

I am not sure but try like this:

put action for form tag and nethos as post <form action="xxxxx" method="yyyyyy">

then try getting as :

if($_POST)
{
$drname=$_POST['drname'];
setcookie("TestCookie", $drname);

}

Simply put, the setcookie function must be called before you do any rendering (i.e.: <form> <h> any html elements). This is because the cookie is passed in the header of a page instead of the body.

[code]
<?php

setcookie("cookie_name", $cookie_data);

?>

<p>First thing you see on the page</p>
[/code]

Sorry guys once again all looks good but will not work here is the code once again.

[code]
//Page 1
<form action="diagnoses/choice.php" method="post">
<input type="text" name="drname" size="24" /> <input type="submit" name="Submit" value="Submit" />
</form>

//Page 2
<?php
if($_POST)
{
$drname = $_POST['drname'];
setcookie("drname", $drname);
}
?>

//Page 3
<?php
echo $_COOKIE["drname"];
?>
[/code]

???????

The code you just posted is working for me

Page 1
[code]<?php

echo '<form action="2.php" method="post">
<input type="text" name="drname" size="24" /> <input type="submit" name="Submit" value="Submit" />
</form>';

?>[/code]

Page 2
[code]<?php

if($_POST)
{
$drname = $_POST['drname'];
setcookie("drname", $drname);
}

?>[/code]

Page 3
[code]<?php

echo "The set cookie is: ". $_COOKIE["drname"];

?>[/code]

It does set the cookie as shown here using the firefox web developer addon.

sorry for all the code but from everything that I can see it should work something seems to be clearing the cookie some where.

thanks again for the help

Okay now I am having trouble with my simple test group of pages. Here is the code that I am using.

[code]
//Page 1
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head>
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<meta name="generator" content="Adobe GoLive" />
<title>Untitled Page</title>
</head>

<body>
<p>
<form method="post" action="test2.php">
<input type="text" name="drname" size="24" /> <input type="submit" name="Submit" value="Submit" />
</form>
</p>
</body>

</html>

//Page 2
<?php
setcookie("drname", $drname);
?>
<META HTTP-EQUIV=Refresh CONTENT=".3; URL=http:test3.php">

//Page 3

<?php
echo $_COOKIE["drname"];
?>
[/code]

Everything works great the first time through. But if I go back to the first page and try entering something different it dose not change the cookie. Is there something I need to add to make that happen? Also if I ever get this working I am going to want to set the cookie so that it never dies. How do I do that?

thanks
