php未将信息写入数据库

试试这个， 首先回显您的查询并将此查询运行到数据库

<?php
            $email = $_POST['email'];
            $first = $_POST['first'];
            $last = $_POST['last'];
            $business = $_POST['business'];
            $home = $_POST['home'];
            $cell = $_POST['cell'];
            $street = $_POST['street'];
            $city = $_POST['city'];
            $state = $_POST['state'];
            $zip = $_POST['zip'];
            $system = $_POST['system'];
            $cameras = $_POST['cameras'];
            $hdd = $_POST['hdd'];

            if(isset($_POST['submit']))
                {
                $connect = mysql_connect('localhost','rebeler_customer','callaway87');
                mysql_select_db("rebeler_customers");

                mysql_real_escape_string($first);
                $last = mysql_real_escape_string($last);
                $business = mysql_real_escape_string($business);
                $home = mysql_real_escape_string($home);
                $cell = mysql_real_escape_string($cell);
                $email = mysql_real_escape_string($email);
                $street = mysql_real_escape_string($street);
                $city = mysql_real_escape_string($city);
                $state = mysql_real_escape_string($state);
                $zip = mysql_real_escape_string($zip);
                $system = mysql_real_escape_string($system);
                $cameras = mysql_real_escape_string($cameras);
                $hdd = mysql_real_escape_string($hdd);

                $query = mysql_query("INSERT INTO `customers`(`email`,`firstname`,`lastname`, `businessname`,`homephone`, `cellphone`,`street`, `city`,`state`, `zip`,`system`, `cameras`, `hdd`) VALUES ('$email','$first','$last','$business','$home','$cell','$street','$city','$state','$zip','$system','$cameras','$hdd')");

}
?>

请不要使用

mysql\uuz

生成新代码。整套函数都已弃用，并可能导致代码不安全（请注意巨大的红色通知：）

相反，使用PDO。下面是一个使用PDO的代码示例。必须提供数据库用户名、密码和数据库名称

$query = "INSERT INTO `customers`(`email`,`firstname`,`lastname`, `businessname`,`homephone`, `cellphone`,`street`, `city`,`state`, `zip`,`system`, `cameras`, `hdd`) VALUES ('$email','$first','$last','$business','$home','$cell','$street','$city','$state','$zip','$system','$cameras','$hdd')";

echo $query;
//$result =mysql_query($query);

• PDO

  -

• PDO:：准备

  -

• PDOStatement:：execute

  -

• PDO:：errorInfo

  -

• PDO:：lastInsertId

  -

试试这段代码，理论上做同样的事情，并且易于调试（PHP>=5.3）：

调试时，它以什么方式失败？在mysql\u error（）中有什么有用的东西吗？在PHP错误日志中？您正在使用并且应该使用。是否可以打印mysql_error（）？错误日志中的query.nothing的值，当我使用e_all&Strict在xampp中运行它时，我得到了一大堆未定义的变量通知，这一个…警告：mysql_fetch_assoc（）希望参数1是resource，布尔值在C:\xampp\htdocs\new_submit.php行中给出6@MosesBolton-你在哪里调用

mysql\u fetch\u assoc（）

？上面给出的代码中没有，这对于sql注入是完全开放的。另外，您可以使用

array\u键

，

array\u值

，以及

内爆

在更少的行中完成同样的事情。您应该尝试解决所提出的问题。@TrippyD否决票不是为了表示您不赞成该方法。这是一个技术上准确的答案，它确实解决了这个问题，因为考虑到问题的细节，代码是按书面形式工作的。
