ERROR IN MYSQLI

[felito]

hi guys

 

i get an error in this code (comment in the code):

 

I

 

if (checkBd ($sql, $db, $valor, $codePass)){

    ($sql = $db->prepare("UPDATE users SET activation = ? WHERE activationLink=?"));

    $valor="1";
    $sql->bind_param('is', $valor, $codePass);

    $sql->execute();

    $sql->bind_result($valor, $codePass); //Warning: mysqli_stmt::bind_result() [mysqli-stmt.bind-result]: Number of bind variables doesn't match number of fields in prepared statement 

    if ($sql->fetch()) {
        header("location: index.php");
        return true;
    }
    else {
        echo "no";
        return false;
    }
$sql->close();
$db->close();
}

 

 

what is the possible problem in the script? an another question, is this way correct to update a boolean?

 

thanks

You cannot retrieve a result from an UPDATE query.

you are correct. Final code

 

if (checkBd ($sql, $db, $codePass)){

$valor=1;
($sql = $db->prepare("UPDATE users SET activation=? WHERE activationLink=?"));

$sql->bind_param('is', $valor, $codePass);

$sql->execute();
header("location: index.php");
return true;
}
else {
echo "no";
return false;
}
$sql->close();
$db->close();
