与 php 中的 SQL 数据库建立安全连接

Making a secure connection to a SQL database in php

我正在尝试保护我的数据库凭据,但它们一直显示在 firebug 控制台中。

我只是想将表单信息保存到数据库中。

我的表格 (form.html)

<form id="Form" method="POST" >
    <table>
        <tr>
            <td>Name:</td>
            <td><input id="name" name="name" type="text" /></td>
        </tr>
        <tr>
            <td>Address:</td>
            <td><input id="address" name="address" type="text" /></td>
        </tr>
        <tr>
            <td>Telephone:</td>
            <td><input id="telephone" name="telephone" type="text" /></td>
        </tr>
        <tr>
            <td>Email:</td>
            <td><input id="email" name="email" type="email" /></td>
        </tr>
    </table>
    <div class="SubmitButton">
        <input type="submit" id="submit" name="submit" value="Submit" />
    </div>
    </form>

    <div id="Response"></div>
</div>

<!-- javascript to handle form data -->
<script type="text/javascript">    
$("document").ready(function(){
    var frm = $('#Form');
    frm.submit(function (ev) {      
        ev.preventDefault();  

        var email = $('#email').val();
       if(email)
       {
            $.ajax({
                type: "POST",
                dataType:"json",
                url: "submit.php",
                data: frm.serialize(),
                success: function () {
                    $('#Response').empty();
                    $('#Response').wrapInner("<span class='SuccessMessage'>Your information has been submitted successfully!</span>")
                    return;
                },
                error: function () {
                 $('#Response').empty();
                 $('#Response').wrapInner("<span class='ErrorMessage'>Your information was not submitted successfully.  Please try again.</span>")
              }
            });
        } else {
            $('#Response').empty();
            $('#Response').wrapInner("<span class='EmailBlankMessage'>Email address is a required field.</span>")
            return;
        }
    });
});
</script>

这是我的 submit.php

<?php
if($_POST)
{
    require(dirname(__FILE__)."/../config.php");

    $name = $_POST["name"];
    $address = $_POST["address"];
    $telephone = $_POST["telephone"];
    $email = $_POST["email"];

    $name = mysql_real_escape_string($name);
    $address = mysql_real_escape_string($address);
    $telephone = mysql_real_escape_string($telephone);
    $email = mysql_real_escape_string($email);

    mysql_query("INSERT INTO XXXXX(name, address, telephone, email) VALUES('$name', '$address', '$address', '$email')"); 


}else { 
    header("Location: /Form.html");
    die();
}

?>

这是我的 config.php

 <?

$hostname = "XXXXXX";
$database = "XXXXXX";
$username = "XXXXXX";
$password = "XXXXXX";

mysql_connect($hostname, $username , $password) or die (mysql_error());
mysql_select_db($database ) or die (mysql_error());

配置文件放在根目录之外。然而,我遇到的两个主要问题是它不会将表单数据插入 table 并且来自 config.php 的数据库凭据也会显示在 firebug 控制台中 post 回复。我不明白我的代码有什么问题。

您在 config.php 中的 php 打开标签是 <? - 这是 short open tag,我认为它在您的配置中被禁用。 config.php 中的 php 不会被解释,而是按原样显示。将其更改为常规打开标签 <?php.

另请注意,mysql 扩展已弃用,您应该切换到 PDO 和准备好的语句。
