Setting a cookie

Question

Trying to learn cookies in PHP to me everything seems fine but it doesnt even set the cookie
here is the code

<?php
    if (isset($_COOKIE['user'])) {
        header('Location: simple.php');    
    } else {
        if (isset($_POST['submit'])) {
            if (isset($_POST['username']) && isset($_POST['password'])) {
                if (isset($_POST['checkbox'])) {
                    $expire = time() + 60 * 60;
                    setcookie('user', $_POST['username'], $expire);
                } else {
                    header('Location: simple.php');
                }
            } else {
                echo 'Please Enter Your Information !';
            }
        } else {
            echo 'Please Submit';
        }
    }
?>

Edit

tried

<?php 

  setcookie("testcookie","testvalue",0); 
  echo $_COOKIE['testcookie'];

?>

Result is

Notice: Undefined index: testcookie in /var/www/php-practice/cookies/test.php on line 1

and it sets the cookie testcookie in browser with the value testvalue
Feel there is some error in $_POST['submit'] because

if (isset($_POST['submit'])) {
    //everything else
} else {
    echo 'Submit Button Problem !';
}

it prints the Submit Button Problem ! here is the HTML of the submit button

<input type="submit" value="Submit" name="submit" />

Looked at this question and tried it but still nothing

I tried everything I could but it doesnt work
Help !

you should use sessions, in most use-cases. in this case, I could simply create a cookie on my side and I'd be "authenticated". — Prisoner, Dec 04 '13 at 11:36
What happens? Did you get redirected to simple.php or is there a message or something else? The setcookie() function looks ok. — Maarkoize, Dec 04 '13 at 11:38
@Prisoner just trying cookies for learning and its not working — Waqas, Dec 04 '13 at 11:38
Make sure to remove any whitespace from the beginning of your php file. — bagonyi, Dec 04 '13 at 11:38
What is the actual error message or behaviour? DO you have errors enabled? — Daniel W., Dec 04 '13 at 11:43
@DanFromGermany It doesnt show any error and yes errors are enable — Waqas, Dec 04 '13 at 11:46
On the top of the page, simply put var_dump($_COOKIE); & check what u r getting — Dev, Dec 04 '13 at 11:46
The cookie doesn't exist at all? Is your Browser accepting cookies? — Maarkoize, Dec 04 '13 at 11:46
Can you please just try following on your server: Create a file with the content: and put this on your server. Execute and just tell, if "testvalue" is printed. — Maarkoize, Dec 04 '13 at 11:50
are you getting $_POST['checkbox'] ?? please check it goes to if condition or else.. — Dev, Dec 04 '13 at 11:51
Use FireBug to see the headers weather the cookies are sent and resent or not — Daniel W., Dec 04 '13 at 12:04

Note you can't set and display cookies on same page at same time. If you set and redirect to another page or reload the page, it will show the cookie value.

<?php 

 setcookie("testcookie","testvalue",0); //this will work
 echo $_COOKIE['testcookie']; // won't work unless reloaded

?>

For your initial script. Ensure that $_POST['checkbox'] exists, is checkbox the name of your html form checkbox input?

//Your HTML form should include this
<input type="checkbox" value="1" name="checkbox" /> 


 if (isset($_POST['checkbox'])) {

        $expire = time() + 60 * 60;
        setcookie('user', $_POST['username'], $expire);

    } else {
        header('Location: simple.php');
    }

Edit your HTML Form to include method="post"

<form method="post">
  <input type="text" name="username" />
  <input type="password" name="password" />
  <input type="checkbox" value="1" name="checkbox" /> 
  <input type="submit" value="Submit" name="submit" />
</form>

it doesnt go inside the `if (isset($_POST['submit'])) {}` in html form i have submit is like that `` — Waqas, Dec 04 '13 at 13:05
ensure your form has method="post" check my answer for modification — andychukse, Dec 04 '13 at 14:15

The $_COOKIE is only available after the site was loaded.
