Variables are not interpolated within single quotes, so you are setting $email to the literal string value '$_POST["email"]', not the value of the post variable. (The '%24_POST%5B%22email%22%5D' you see is just the urlencoded value, which is how the strings have certain characters "escaped".)
You should not have to quote the variables at all when all you want is the value of the variable. The unexpected T_ENCAPSED_AND_WHITESPACE error is because of a quirk in PHP: associative array indexes for an array variable being used within a double-quoted string must [i]not[/i] be quoted. What makes this confusing is that when not within a double-quoted string, they need to be quoted. :rolleyes: But again, there's no reason to be quoting it in this example.
Assuming you're positive the email value is populated, all I can think is that there's something about it that messes up the urlencoding. If using PHP 5, see what happens with this:
If using PHP4, try this instead of setrawcookie:
[RESOLVED] Revisting the Setcookie() Function
Firstly, I am starting a new thread because I would like to get some new eyes on this problem. I have another thread going, but it is getting long, drawn out and hard to read. With that said, here is my problem:
When I try to set a cookie with this code:
[code=php]setcookie (“please”, “work”);
It works. I get the cookie named please, with a value of work.
When I try to set a cookie with this code:
[code=php]$working = ‘work’;
setcookie (“please”, “$working”);
It works. I get the cookie named please, with a value of work.
When I try to set a cookie with this code:
[code=php]$email = $_POST[’email’];
setcookie (“please”, “$email”);
It doesn’t work. No cookie is even written.
when I echo $_POST[’email’] I get the email address I entered in the previous form.
The ONLY difference I see is that I have a quote around ‘work’ and no quote around $_POST[’email’].
So, I did this:
[code=php]$email = “$_POST[’email’]”;
setcookie (“please”, “$email”);
Notice the quotes around $_POST[’email’]. When I did that, I got this error returned:
[QUOTE]
Parse error: parse error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /home/content/t/r/e/trevzilla/html/getfile.php on line 4
So, for giggles, I changed the single/double quotes around to this:
[code=php]$email = ‘$_POST[“email”]’;
setcookie (“please”, “$email”);
And I finally got a cookie to write. But guess what the value is! It sure isn’t an email address! The Value of the cookie came out to be this:
[QUOTE]
%24_POST%5B%22email%22%5D
So, with that long drawn out explanation, does anyone know what is going on here? Why isn’t a cookie writing with the email address in the value?
