所以我有这个错误，我无法弄清楚什么是错的：

Fatal error: Call to a member function bind_param() on a non-object in /home1/tony1964/public_html/2v2tournaments/action.php

register.php：

        <?php

        }
        else {echo "Error: Incorrect Reg_type";}
    ?>

action.php的：

                $stmt = $con->prepare("INSERT INTO `team_type_5` (`teamname`,`region`,`teamleader`,`teammember1`,`teammember2`,`teammember3`,`teammember4`,`wins`,`loses`) VALUES (?,?,?,?,?,?,?,?,?)");

                $stmt->execute();
                $stmt->close();
            }
            else {echo "Error: Unknown, Contact Admin";}
        ?>

有人有任何想法吗？

Answer 1

您的某些准备语句中有错误。

请将您的3 $stmt = $con->prepare(...)更改为：

if (!($stmt  = $con->prepare("....")) || !is_object($stmt)) {
    die( "Error preparing: (" .$con->errno . ") " . $con->error);
}

PHP错误：bind_param（）
