搜索表格以确认然后更新表格行

Question

hate to ask because I've been trying to do all of this on my own but it just will not work, i've searched everywhere and it says I'm doing it correctly

include "db.inc.php";

$ip = $_SERVER['REMOTE_ADDR'];
$ip = mysql_real_escape_string($ip);
$getcount = mysql_query("SELECT * FROM captcha WHERE ip='$ip'");
$resultc = mysql_result($getcount, 0, count);

if($resultc !== "5"){
    #header("Location: index.php");
    echo "don't work";
}else if($resultc == "5"){
    if (!isset($post)){
        $_SESSION['secure'] = substr(str_shuffle($charset), 0, 6);
    }else{
        if ($_SESSION['secure']==$post){
            mysql_query("UPDATE captcha SET count=0 WHERE ip='$ip'");
        }else{
            $error_message = "Incorrect, Try again";
            $_SESSION['secure'] = substr(str_shuffle($charset), 0, 6);
        }
    }
}

its searching the table for the matching ip, getting the number in count, if it does not = count it will echo "don't work" if it does it will do the captcha checks, everything in captcha check works except for the UPDATE

What i'm trying to do here is, I've made a custom Captcha which works, what i need to do now is when a users count is 5 which will add 1 to the current number everytime they successfully shrink a URL, I need it to check the db if it is not 5 I do not want them to have access to the captcha page so I need them to be redirected to the index page, if it is 5 it will go through the captcha which works, but I need to reset the count back to 0 after they enter the captcha code correctly, but it will not update the row.

@cody: you forgot quotes around "count".
Replace:

$resultc = mysql_result($getcount, 0, count);  

with:

$resultc = mysql_result($getcount, 0, 'count');
