我正经历着噩梦般的一天，并试图修改 html 和 php 以将注册表单的信息插入 mysql。下面是html表单和php提交页面。我已经开始使用与数据库的 sql 连接，并为添加函数设置了一些变量。

今天是星期一，我想我有点迷失了——任何帮助都会很棒:-) 

<?php

$dbcnx = @mysql_connect('localhost', 'user', 'pass');
        if (!$dbcnx) {
                exit('<p>Unable to connect to the ' . 'database server at this time.</p>');
        }
        if (!@mysql_select_db('signp',$dbcnx)) {
                exit('<p>Unable to locate the file ' . 'database at this time.</p>');
        }



if ($action == "add") {
/* ****************************** Do this if we are adding a new record */
        $query = "INSERT INTO connect VALUES ()";

        $result = mysql_query( $query );        
        if(!$result){
                die ("could not query database: <br />".mysql_error());
        }       
        $d_id = $inserted_id = mysql_insert_id();
        $dname = "";
        $demail = "";
        $dpassword = "";
}

// Error reporting:
error_reporting(E_ALL^E_NOTICE);

// This is the URL your users are redirected,
// when registered succesfully:

$redirectURL = 'http://ip/index.html';

$errors = array();

// Checking the input data and adding potential errors to the $errors array:

if(!$_POST['name'] || strlen($_POST['name'])<3 || strlen($_POST['name'])>50)
{
        $errors['name']='Please fill in a valid name!<br />Must be between 3 and 50 characters.';
}

if(!$_POST['email'] || !preg_match("/^[\.A-z0-9_\-\+]+[@][A-z0-9_\-]+([.][A-z0-9_\-]+)+[A-z]{1,4}$/", $_POST['email']))
{
        $errors['email']='Please fill in a valid email!';
}

if(!$_POST['pass'] || strlen($_POST['pass'])<5)
{
        $errors['pass']='Please fill in a valid password!<br />Must be at least 5 characters long.';
}
// Checking whether the request was sent via AJAX
// (we manually send the fromAjax var with the AJAX request):

if($_POST['fromAjax'])
{
        if(count($errors))
        {
                $errString = array();
                foreach($errors as $k=>$v)
                {
                        // The name of the field that caused the error, and the
                        // error text are grouped as key/value pair for the JSON response:
                        $errString[]='"'.$k.'":"'.$v.'"';
                }

                // JSON error response:
                die     ('{"status":0,'.join(',',$errString).'}');
        }

        // JSON success response. Returns the redirect URL:
        echo '{"status":1,"redirectURL":"'.$redirectURL.'"}';

        exit;
}

// If the request was not sent via AJAX (probably JavaScript
// has been disabled in the visitors' browser):

if(count($errors))
{
        echo '<h2>'.join('<br /><br />',$errors).'</h2>';
        exit;
}



// Directly redirecting the visitor:

header("Location: ".$redirectURL);
?>

首先，$action没有定义。

其次，$query = "INSERT INTO connect VALUES ()";不插入任何帖子数据。

第三，你不应该使用 mysql_* 函数，它们在 php.net 上被劝阻，所以这应该是你不应该使用它们的一个好兆头。

第四，作为一个脚注，不要使用@.
