HTML mySQL表单不能正常工作

Question

我想在我的网站上设置一个表单，但它给了我一个错误，我确定我的代码正确但仍然无法正常工作。

我正在砸我的头试图找到任何帮助，将不胜感激的问题。 这是PHP脚本：

<?php 

$host=""; // Host name 
$username=""; // Mysql username 
$password=""; // Mysql password 
$db_name=""; // Database name 
$tbl_name="orders_mysql"; // Table name 

// Connect to server and select database. 
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB"); 

// Get values from form 
$name=$_POST["name"]; 
$lastname=$_POST["lastname"]; 
$address=$_POST["address"]; 
$address2=$_POST["address2"]; 
$city=$_POST["city"]; 
$state=$_POST["state"]; 
$zip=$_POST["zip"]; 
$country=$_POST["country"]; 
$phone=$_POST["phone"]; 
$bra_size=$_POST["bra_size"]; 
$bra_color=$_POST["bra_color"]; 
$cami_size=$_POST["cami_size"]; 
$cami_color=$_POST["cami_color"]; 
$email=$_POST["email"]; 

// Insert data into mysql 
$sql="INSERT INTO orders_mysql(name, lastname, address, address2, city, state, zip, country, phone, bra_size, bra_color, cami_size, cami_color, email)VALUES('$name', '$lastname', '$address' '$address2', '$city', '$state', '$zip', '$country', '$phone', '$bra_size', '$bra_color', '$cami_size', '$cami_color', '$email')"; 
$result=mysql_query($sql); 

// if successfully insert data into database, displays message "Successful". 
if($result){ 
echo "Successful"; 
echo "<BR>"; 
echo "<a href='index.php'>Back to main page</a>"; 
} 

else { 
echo "ERROR"; 
} 
?> 

<?php 
// close connection 
mysql_close(); 
?> 

这是HTML：

好了，所以这里是交易，我可以在脚本中看到有以下担忧：

首先，尝试进行连接，如下所示：

mysql_connect($host, $username, $password) 

（下称“从变量删除）。第二，我看到你正在向数据库插入一个新的寄存器，而我看不到任何“id”列，你的数据库表是否与索引一起工作？你有自动增量值吗？如果是的话，你应该格式化你的SQL如下：

"INSERT INTO orders_mysql(id, name, lastname, address, address2, city, state, zip, country, phone, bra_size, bra_color, cami_size, cami_color, email)VALUES(NULL, '$name', '$lastname', '$address' '$address2', '$city', '$state', '$zip', '$country', '$phone', '$bra_size', '$bra_color', '$cami_size', '$cami_color', '$email')"; 

，你可以尝试，以解决了你的问题，其他的事情，情况如下： 复制你的SQL语句，并用实际值替换变量，只写randon的话，是这样的：有这个

"INSERT INTO orders_mysql(name, lastname, address, address2, city, state, zip, country, phone, bra_size, bra_color, cami_size, cami_color, email)VALUES('asd', 'asd', 'asd' 'asd', 'asd', 'asd', 'asd', 'asd', 'asd', 'asd', 'asd', asd', 'asd', 'asd')"; 

，使用phpMyAdmin，粘贴SQL语句在你的数据库SQL查询框中，并尝试添加它，这会给你一个错误，或者是成功的，如果它是一个错误，你会得到关于为什么你的陈述失败的描述。

是ussually使得语句失败了，其他的事情是，你必须添加“'”的列名：

"INSERT INTO orders_mysql(´name´, ´lastname´, ´address´, ´address2´, ´city´, ´state´, ´zip´, ´country´, ´phone´, ´bra_size´, ´bra_color´, ´cami_size´, ´cami_color´, ´email´)VALUES('$name', '$lastname', '$address' '$address2', '$city', '$state', '$zip', '$country', '$phone', '$bra_size', '$bra_color', '$cami_size', '$cami_color', '$email')"; 

让我们试着任一选项，并让我们与您取得错误更新为了尝试用更多的信息来解决这个问题。

请记住，由mysql扩展提供的API将被弃用，并且不再支持mysql_connect（或任何mysql_ *）之类的函数。请看看这些链接：

MySQL的 - 选择一个API - http://us2.php.net/manual/en/mysqlinfo.api.choosing.php

PHP：正确的方式 - 数据库 - http://www.phptherightway.com/#databases与PDO

工作是非常简单的。为了与MySQL数据库连接，我们可以做这样的事情：

<?php 
$hostname = 'localhost'; 
$username = 'username'; 
$password = 'password'; 

try { 
    $db_host = new PDO("mysql:host=$hostname;dbname=mysql", $username, $password); 
    echo 'Connected!'; 
} 
catch(PDOException $e) { 
    echo $e->getMessage(); 
} 

既然我们已经连接，也许有些INSERT语句：

<?php 
try { 
    $cons = $db_host->exec("INSERT INTO orders_mysql(name, 
          lastname) VALUES('foo', 'bar', 'baz', 'bar2')"); 

    echo $cons; // number of affected rows 
} 
catch(PDOException $e) { 
    echo $e->getMessage(); 
} 

即使我们可以更好地准备我们的SQL执行之前：

<? 
$name  = 'foo'; 
$lastname = 'bar'; 
// [...] 
$email = 'qux'; 

// constructing 
$query = $db_host->prepare("SELECT * FROM orders_mysql 
          WHERE name = :name 
          AND lastname = :lastname"); 
// binding params 
$query->bindParam(':name', $name, PDO::PARAM_STR, 50); 
$query->bindParam(':lastname', $lastname, PDO::PARAM_STR, 50); 
// executing 
$query->execute(); 
// fetching results 
$results = $query->fetchAll(); 

// displaying 
foreach($results as $tuple) { 
    echo "Name: {$tuple['name']} - Lastname: {$tuple['name']}"; 
} 

再见！
