Question

这是表格的代码：

   <div id="regform">
   <div id="regform-top">
   <h2>User Registration</h2>
   <p>Please complete this form</p>
   </div>

   <form id="register-form" name="register-form" action="submit.php"  method="post"    
   class="validation">
   <fieldset>

   <table>

  <tr>
  <td>
  <div class="fieldgroup">
  <label for="user-name">User name*: </label>
  <input type="text" id="name" name="name" value="" size="12" class="inpt" /><br    
  class="clear" />
  </div>
  <div class="fieldgroup">
  <label for="password">Password*: </label>

  <input type="password" id="password" name="password" value="" size="12" class="inpt"     
   /><br class="clear" />

  </div>
  </td>
  <td id="form-note">
  <br />

  <p><strong>Form  Instructions</strong></p>

  <p>*Required Field</p>
  </td>
  </tr>

  </table>


  <table id="bottom-reg">

  <tr>
  <td><br />

  <div class="fieldgroup">

  <input type="text" id="address1" name="address1" value="" size="12" class="inpt" />   
  <br class="clear" />

  <label for="address2">Address 2</label>

  </td>

  </tr>

  </table>

  <input type="submit" value="Register" class="submit-btn" />
  </fieldset>
  </form>

这是submit.php的代码：

     <?php

     $con = mysql_connect("localhost","viatechp_invacar","storefront72");
  if (!$con)
  {
    die('Could not connect: ' . mysql_error());
  }


  mysql_select_db("viatechp_invacare", $con);



    $sql="INSERT INTO registration(username,password,fname,lname,group,
    address1,address2,address3, email,city,state,zip,country )
    VALUES
    ('$_POST[name]','$_POST[password]', '$_POST[firstname]','$_POST[lastname]','  
    $_POST[group]','$_POST[address1]','$_POST[address2]','$_POST[address3]',                                                           
   '$_POST[email]','$_POST[city]','$_POST[state]','$_POST[zip]','$_POST[country]'

    )" ;

  $query = mysql_query($sql) or die(mysql_error());

  $results = mysql_fetch_assoc($query);

   if ($results) { 
  echo 'The query returned ' . $results[ 'registration' ];
  } else {
  echo 'The query did not return any results';
  } ?>


  echo $sql;


  ?>

显示错误：

您的SQL语法有错误;查看与您的MySQL服务器版本对应的手册，以便在“group，address1，address2，address3，email，city，state，zip，country”附近使用正确的语法VALUES（'sdfdsf'在第1行

Answer 1

group是一个SQL关键字。如果这是你的一个字段的名称，你必须用`like so：

将它括起来

`group`,`address1`,...

这告诉mySQL它是一个字段名而不是关键字。最好将所有字段都包含在`中，以防止您可能没有注意到的任何错误。

Answer 2

由pburgess发现。 GROUP，ORDER是我们在编程时使用的一些常用字段名称。确保使用反引号group将它们括起来，这总是一个好习惯。

$sql="INSERT INTO registration(username,password,fname,lname,`group`,
    address1,address2,address3, email,city,state,zip,country )
    VALUES
    ('$_POST[name]','$_POST[password]', '$_POST[firstname]','$_POST[lastname]','  
    $_POST[group]','$_POST[address1]','$_POST[address2]','$_POST[address3]',                                                           
   '$_POST[email]','$_POST[city]','$_POST[state]','$_POST[zip]','$_POST[country]'

    )" ;

Answer 3

试试这个

$sql="INSERT INTO registration(`username`,`password`,`fname`,`lname`,`group`,
       `address1`,`address2`,`address3`, `email`,`city`,`state`,`zip`,`country` )
       VALUES
      ('$_POST[name]','$_POST[password]', '$_POST[firstname]','$_POST[lastname]',
      '$_POST[group]','$_POST[address1]','$_POST[address2]','$_POST[address3]',                                                           
      '$_POST[email]','$_POST[city]','$_POST[state]','$_POST[zip]','$_POST[country]')" ;

因为您有一些字段名称是保留关键字，例如您有group

Answer 4

您的$_POST值缺少引号，请尝试更新

 $sql="INSERT INTO registration
     (`username`,`password`,`fname`,`lname`,`group`,`address1`,`address2`,`address3`, `email`,`city`,`state`,`zip`,`country`)
     VALUES
     ('$_POST[\"name\"]','$_POST[\"password\"]',$_POST[\"firstname\"]','$_POST[\"lastname\"]','  
            $_POST[\"group\"]','$_POST[\"address1\"]','$_POST[\"address2\"]','$_POST[\"address3\"]',                                                           
           '$_POST[\"email\"]','$_POST[\"city\"]','$_POST[\"state\"]','$_POST[\"zip\"]','$_POST[\"country\"]'

            )" ;

Answer 5

这太晚了，但这可能对某人有所帮助。每当你想检查为什么你的查询没有＆＃39;总是尝试回应你的查询并将其粘贴到phpmyadmin，它会抛出mySQL错误，这更容易理解查询中的问题

为什么mysql代码没有在数据库中提交值
