Cookie未被设置

Question

Could you please help me? My website does not set the following simple cookie. Although some other login scripts does but this one does not work. Thanks

test.php

...

<form action="test2.php" method="post">
        Email: <br />
        <input type="email" name="email" value=""/> <br />
        <input type="submit" name="submit" value="Next"/> 
</form>

...

test2.php

<?php ob_start(); ?>

<?php
// call the header of the page
require('header.html');

// connect to database
require "connect.php";
?>

<?php
    $email = $_POST['email'];

    // set cookie
    $one_hour = time() + 3600;
    $set = setcookie(user_email, $email, $one_hour);

    if($set == TRUE) {
        print '<p> Cookie set</p>';
    } else {
        print '<p> Cookie not set</p>';
    }

// call footer of the page
require('footer.html');
?>

<?php ob_flush(); ?>

After running the above scripts, I get this error:

Warning: Cannot modify header information - headers already sent by (output started at /websites/public_html/test2.php:1) in /websites/public_html/test2.php on line 16

Cookie not set

• PS: Line 16 on my script is "$set = setcookie(email_noaccount, $email, $hr);"

Answer 1

just change above code in following way and try, put ob_start() after require()

<?php
require "connect.php";
require('header.html');
?>
<?php ob_start(); ?>
