setcookie() is the main function that is used to work with cookiesin PHP
parameters are as follows:
setcookie (string name , string value , int expire , string path , string domain
, int secure)
Cookies are sent to the user's computer thru the header: in static files, because
this is the case you must set, expire your cookies before displaying anything
thru your script.. before any echo() and/or print() functions. This is not a PHP
setback, it the way HTML works :o) Check out this simple function i have written.
. .
function cookie($function, $value) {
if ($function == "set") {
setcookie ("CookieValue", "$value",
time() + 14400);// Cookie is Valid for 4 hours. 3 value
in function is the time expiration in seconds. ...
3600 seconds = 1 hour
return true;// cookie
set, return true
} else if ($function = "logout") {
setcookie
("CookieValue", "$value", time() - 14400);// Cookie is now expired as we set the expiration value to 4 hours ago
return true; // logout
complete
} else if ($function = "check") {
if (isset($CookieValue))
{
if ($CookieValue == $value)
{
print("ALL
GOOD.. cookie verified");
return
true;
} else {
print("Value
does not much cookie");
return
false; // Failed, so return false
}
}
} else {
return false;// Failed, since no operations match
}
}
?>

the best php cookie tutorial I've seen
yet
| 10/19/2001 11:33:34 PM:rag
hey, your tutorial helped me with my
site with cookies. But I have one
question to ask. I have a form that
checks whether or not the name/password
was valid through a mysql database
query.
Now, if I were to use your
function, how would I call it and set
values from the form, onto the value
parameter? What I mean is that if the
form is already outputted, how am I
supposed to validate and set a cookie
(since the cookie is in the header and
once a document is outputted, it
doesn't work).
The process is:
Fill
out the name/password
Validate the
name/password
If true, set cookie, if
false, don't set (or expire it).
is
it possible to do it all in 1 php
page?
Thanks a lot
