Cookie help

[Tim Dobson]

I am new to php and just started doing a bit of stuff with cookies and now got slightly stuck.

I am fully aware on how to create a cookie, make a cookie invalid.

im also aware of

print_r($_COOKIE); 

to print the value of the cookie on the page... but what if i wanted $thecookie value to be the value of the cookie then wanted to print $thecookievalue

Im not going to echo $thecookievalue i just need to value of the cookie in a string so i can set an if statement to check what the value of the cookie is so i can set the correct page of the user.

Thanks

To get the cookie value, wouldn't you just do $_COOKIE['name'] and then manipulate that?

[Tim Dobson]

Yea sure i can do that but new to all this stuff and what ever iv tried has failed just need an example to show me how its done lol

It sounds like what you want is to retrieve the cookie value from a cookie without actually manipulating the cookie itself.

$thecookievalue=$_COOKIE['name'];

that's it.

Ah yes i did that and it pulled out an error but i figured it out so i asked because i wasent sure if this was what i was doing wrong but thanks

What is the error? Just like any variable, if you try to use a variable that has no value it will give you a warning (not an error, but similar) if the error reporting is high enough. You can fix this by making sure it's set first:
$var = ''; //set it to blank
if (isset($_COOKIE['var'])) { $var = $_COOKIE['var']; }

There are lots of other ways to approach it as well. You can also just lazily suppress the error, but that's not a great idea (since it can be unpredictable), but at least you won't get an error message for visitors:
echo @$_COOKIE['var'];
(the @ symbol means 'and don't show an error if there is one')
