HTML mySQL表單不能正常工作

Question

我想在我的網站上設置一個表單，但它給了我一個錯誤，我確定我的代碼正確但仍然無法正常工作。

我正在砸我的頭試圖找到任何幫助，將不勝感激的問題。 這是PHP腳本：

<?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(); 
?> 

這是HTML：

 <form action="insert_ac.php" id="order" method="post" > 
      <center><span class="products_title">Select Quantity, Size and Color</span> 
      <img id="product" src="/images/seamlesscami.jpg" alt="Seamless Cami">

好了，所以這裏是交易，我可以在腳本中看到有以下擔憂：

首先，嘗試進行連接，如下所示：

mysql_connect($host, $username, $password) 

（下稱「從變量刪除）。第二，我看到你正在向數據庫插入一個新的寄存器，而我看不到任何「id」列，你的數據庫表是否與索引一起工作？你有自動增量值嗎？如果是的話，你應該格式化你的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')"; 

，你可以嘗試，以解決了你的問題，其他的事情，情況如下： 複製你的SQL語句，並用實際值替換變量，只寫randon的話，是這樣的：有這個

"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，粘貼SQL語句在你的數據庫SQL查詢框中，並嘗試添加它，這會給你一個錯誤，或者是成功的，如果它是一個錯誤，你會得到關於爲什麼你的陳述失敗的描述。

是ussually使得語句失敗了，其他的事情是，你必須添加「'」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')"; 

讓我們試着任一選項，並讓我們與您取得錯誤更新爲了嘗試用更多的信息來解決這個問題。

請記住，由mysql擴展提供的API將被棄用，並且不再支持mysql_connect（或任何mysql_ *）之類的函數。請看看這些鏈接：

MySQL的 - 選擇一個API - http://us2.php.net/manual/en/mysqlinfo.api.choosing.php

PHP：正確的方式 - 數據庫 - http://www.phptherightway.com/#databases與PDO

工作是非常簡單的。爲了與MySQL數據庫連接，我們可以做這樣的事情：

<?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(); 
} 

既然我們已經連接，也許有些INSERT語句：

<?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(); 
} 

即使我們可以更好地準備我們的SQL執行之前：

<? 
$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']}"; 
} 

再見！
