Cookie Problems

[Lexar]

Howdy, I'm having some issues using cookies. I've identified the problematic line being in my login.php file, which is the action="POST" of my login form.

[code]
<?php
if(empty($_POST['name']) || empty($_POST['pass']))
{  ?>
    <b>Fill All Details </b>
              <?php exit;
}
else
{
    //Colllect the details and validate
    $time = time();
    $name = $_POST['name'];
    $pass =md5($_POST['pass']);
    $check = 'ON';
   
$db = mysql_connect("-----", "-----","-----") or die(mysql_error());
    mysql_select_db("-----",$db) or die(mysql_error());
    $query = "select * from Customer where Username='$name' and Password='$pass'"; 
    $sql = mysql_query($query) or die(mysql_error());
    $count = mysql_num_rows($sql);
   
    if ($count == 1)
    {
        $cookie_data = $name.'-'.$pass.'-'.$access; 
        if($check=='ON')
        {

            if(setcookie ("cookie_info",$cookie_data, $time+3600)==TRUE)
            {
    ?> if check is on <?PHP
                echo "Cookie SET".$cookie_data; ?>
                <a href='logout.php'>Logout</a>
               
            <? }
        }
    }
    else
    {
        echo "Authentication Failed";
        exit;
    }//
   
}
?> [/code]


That's the entire file. I've found that the "if check is on" line will display if it's before the following if statment, but not inside of it.

[code]if(setcookie ("cookie_info",$cookie_data, $time+3600)==TRUE)
[/code]

Is it possible that headers have already been sent?  Try calling setcookie() (with any arguments) at the very top of your script, right after the first [code=php:0]<?php[/code], and see if that call succeeds or fails.

Looks like you're right. Know of any way to fix this?

I put an additional if at the top with no arguements, which failed. What do you suggest?

You can always throw in ob_start() at the top of your script.  It caches everything until you're ready to print out the data (or the file is finished running) so that you can edit headers at any point in your script.
