HELP!!! Keep getting problem with undefined index....

[RossBryan]

I really dont get it now i keep having this problem and there always seems to be a different solutiion. Im defining variables and yet its telling me that they arent defined; so confusing :s

Notice: Undefined index: user in C:\xampp\htdocs\Care2Share\design\status.php on line 4
Notice: Undefined index: id in C:\xampp\htdocs\Care2Share\design\status.php on line 5

<?php 

$username = $_SESSION['user'];
$userid = $_SESSION['id'] ;

if ($username)
{
        echo "You are logged in as $username"; 
}

else
{
        echo "<form action='loginC2S.php' method='POST' >
 
<table style='margin-left: auto; margin-right: auto;'>
<tr>
        <td><input type='text' id='usernamebox' name='user' tabindex='1' value='Username' class='textbox' onfocus='usernamebox_focus();' onblur='usernamebox_blur();'></td>
        <td><a href='register.php'>Register</a></td>
</tr> 
<tr>
    <td><input type='text' id='passwordbox' name='pass' tabindex='2' value='Password' class='textbox' onfocus='passwordbox_focus();' onblur='passwordbox_blur();' /></td>
    <td><input type='submit' name='login' value='login' tabindex='3' class='button'> </td>
</tr>
</table>
</form>";
}

?>

I know coding can be frustrating at times but im seeing myself not having any hair left the way this is going lol

You should ALWAYS use session_start() at the top of ANY script which uses sessions.

session_start DOES NOT just start sessions, it also RESUMES existing sessions (in other words reopens them). It's clearly stated on the php manual

I have used session_start(); at the top of the page i just didnt include it in the post sorry.

If you are going to check to see if your variable has a value then you need to use the isset() function.

Thanks that worked great but ended up causing another problem with another section of coding in an associated file:

Notice: Use of undefined constant numrows - assumed 'numrows' in C:\xampp\htdocs\Care2Share\loginC2S.php on line 62

$numrow =mysql_num_rows($query); 
     

    if (numrows == 1) 
    { 
        $rows = mysql_fetch_assoc($query); 
        $dbuser = $rows['username']; 
        $dbid = $rows['id']; 
         
        //logs user in         
        $_SESSION['user'] =$dbuser; 
        $_SESSION['id'] = $dbid;     
        echo "<center>You have been logged in.</center>"; 
    }

if (numrows == 1)
should be
if ($numrow == 1)

No offence but if session_start was used in your code why on earth didn't you show it? .. oh hang on... i see..
