Question

正如您所见，div1将成为第一个框。句子＆＃34;我的名字叫小明。＆＃34;应该出现在第一个框内。这句话＆＃34;我的名字叫小明。＆＃34;来自数据库，已从数据库中检索出来。我想要这句话＆＃34;我的名字叫小明。＆＃34;显示在第一个框内而不是（http://pho.to/66hLl）。请单击链接以查看句子现在出现的位置。我想要句子＆＃34;我的名字叫小明。＆＃34;而是出现在顶部框中，以便我可以将单个字符拖动到第二个框中！谢谢！:)

在尝试访问它们之前，您需要实例化PHP声明

 <?php
// Connect to database server
mysql_connect("localhost", "root", "password") or die (mysql_error ());

// Select database
mysql_select_db("login") or die(mysql_error());

// set utf8 unicode mode to set chinese character 

mysql_query ( 'SET NAMES utf8' ); 

$strSQL = "SELECT * FROM chinesesen WHERE id=1 ;";


//create an array with numbers 1-4
 $order = array(1,2,3,4);

//shuffle them in random order
 $rs = mysql_query($strSQL);


 while($row = mysql_fetch_array($rs)) {

    $sentence =  "<dt>Sentence:</dt><dd>" . $row[$order[0]] . " " . $row[$order[1]] . " " .
   $row[$order[2]] . " " . $row[$order[3]] ."</dd>";

}

 mysql_close();
 ?>


  <div id="div1" ondrop="drop(event)" ondragover="allowDrop(event)">
  <section id="drag1">

  <a class= "<?php  echo "<dt>Sentence:</dt><dd>" . $row[$order[0]] . " " .     

   $row[$order[1]] . " " .
   $row[$order[2]] . " " . $row[$order[3]] ."</dd>";  ?>
   <?php echo $sentence;?>
   </a>
   <div width="100" height="100"  
   draggable="true" ondragstart="drag(event)"/></div>



<div id="div2" ondrop="drop(event)" ondragover="allowDrop(event)"></div>

编辑

如果你想做我认为你想做的事情......那么这可能是......

  <?php foreach($row as $r){;?>

    <div width="100" height="100" draggable="true" ondragstart="drag(event)"/>
       <?php echo $r;?>
    </div>

   <? };?>

检索要显示的数据以进行拖放
