Cookie PHP not set

Question

I'am trying to set a cookie in a php file (yesterday it worked, today it does not)

I made the cookie and now i'm trying to delete is by setting it to a null-value. Still the cookie is not being made.

I already deleted the cookies in my browser aswell.

Can someone help me?

 setcookie("winkelwagen", "", '/');
 if(!isset($_COOKIE["winkelwagen"])) {
 echo "<br>Cookie is not set!";
 } else {
 echo "<br>Cookie '" . $_COOKIE["winkelwagen"] . "' is set!";
 echo "<br>Value is: " . $_COOKIE["winkelwagen"];
 }

I'm getting "Cookie is not set" as output

• ksg91: FYI: You cannot access cookie on the same request after setting it. Cookies are sent by browser as a part of HTTP Request Headers. And Cookies are sent by server as a part of HTTP Response Headers. So your HTTP request will not have the cookie which you are just setting in the response.

Answer 1

This is supposed to fail / the expected behaviour:

setcookie("winkelwagen", "", '/');
if(!isset($_COOKIE["winkelwagen"])) {
 echo "<br>Cookie is not set!";
}

According to the manual (emphasis added by me):

Once the cookies have been set, they can be accessed on the next page load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.

So your cookie will never be available when you set it, it will be available on the next page you load.

• user3475797: Yesterday I did try this: setcookie("winkelwagen", ""); and the output (echo's) were fine. it said cookie ... is set.
• jeroen: @user3475797 It will be if you have loaded the page before. Probably a previous cookie expired somewhere today / yesterday.
• user3475797: The thing is, even if i make a cookie with another name, that cookie is also not being created
• jeroen: @user3475797 Also check the manual for the exact order / meaning of the parameters.
• jeroen: @sergio Yep, it's a combination of both our answers :-)

Answer 2

You've made a mistake, you didn't setlife time (it is third parameter), but you set there path '/', which must be the fourth parameter. Also cookie doesn't set with empty value.

From the docs:

If the value argument is an empty string, or FALSE, and all other arguments match a previous call to setcookie, then the cookie with the specified name will be deleted from the remote client.

Use this:

 setcookie("winkelwagen", "some_value",time() + (86400 * 30), '/') //for eaxmle 86400 = 1 day

• user3475797: When i do: setcookie("winkelwagen", ""); it also does not work. So just name and value
• sergio: try as in my example, it will set after reload the page.
• user3475797: Still no change. Cookie is not set
• sergio: Do you reload the page? this works setcookie("winkelwagen11", "some_value",time() + (86400 * 30), '/'); As in my example. I checked.
• user3475797: Yes i reloaded the page
