當我點擊register.php文件中註冊。幫幫我！

Register.php

<form id='register' action='RegisterCode.php' method='post' accept-charset='UTF-8'> <table> 
     <tr> <td> Name: </td> <td> <input type="text" name="Name" maxlength="50" /> </td> </tr> 
     <tr> <td> Age: </td> <td> <input type="text" name="Age" maxlength="2" /> </td> </tr> 
     <tr> <td> Contact: </td> <td> <input type="text" name="Contact" maxlength="8" /> </td> </tr> 
     <tr> <td> Email: </td> <td> <input type="text" name="Email" maxlength="200" /> </td> </tr> 
     <tr> <td> Gender: </td> <td> <input type="text" name="Gender" maxlength="2" /> </td> </tr>  <tr> <td> Address: </td><td> <input type="text" name="Address" maxlength="100"/></td></tr> 
     <tr> <td> Which Industry/ Occupational Group: </td> <td>  
     <select name="Group">  <option value="Student">Student</option>  <option value="Employed">Employed</option>  <option value="Unemployed">Unemployed</option>  <option value="Retired">Retired</option> 
      </select> 
       <tr> <td> How did you know about this event: </td> <td>  
     <select name="Event">  <option value="Online">Online</option>  <option value="Newspaper">Newspaper</option>  <option value="Friend">Friend</option>  </select> 

       <tr><td></td><td><input class="formstylethree" type="submit"></td></tr> </table></form> 

RegisterCode.php

<?php require_once("includes/connection.php");?> <?php require_once("includes/functions.php"); ?> <?php $sql="INSERT INTO registration(Name, Age, Contact, Email, Gender, Address, Group, Event) VALUES ('$_POST[Name]','$_POST[Age]','$_POST[Contact]','$_POST[Email]','$_POST[Gender]','$_POST[Address]','$_POST[Group]','$_POST[Event]')"; 

if (!mysql_query($sql,$connection)) { die('Error: ' . mysql_error()); } else { $location="index.php"; header("Location: {$location}"); echo "1 record added" . $sql; } 

mysql_close($connection); ?> 

登記表

Name  varchar (50) 
Age  int(2) 
Contact varchar(8) 
Email  varchar(200) 
Gender varchar(200) 
Address varchar(200) 
Group  varchar(150) 
Event  varchar(150) 

Answer 1

括的字段名稱（一個或多個）與`（反引號）

`Group`, `Event` 

名稱Group是MySQL

一個 reserved word

Answer 2

嘗試串聯：

VALUES('".$_POST['Name']."','".$_POST['Age']."',... 

Answer 3

對於保留的關鍵字，使用`， 還首次改變這樣的查詢

$sql="INSERT INTO registration(Name, Age, Contact, Email, Gender, Address, `Group`, `Event`) VALUES ('".$_POST[Name]."','".$_POST[Age]."','".$_POST[Contact]."','".$_POST[Email]."','".$_POST[Gender]."','".$_POST`[Address]."','".$_POST[Group]."','".$_POST[Event]."')";
