无法对数据库中的多个表数据进行排序？

我对列“cena”（eng：price）中的数据进行排序时遇到了一些问题。（塞尔维亚语，英语，德语），我想显示，在一个页面，我可以按价格（cena）排序数据，我做了多种语言的网站，我为每种语言slike，en_slike，ger_slike和日期（slike_id），当我运行页面时，一切都很好，但是当我尝试按照cena（价格）对图片进行排序时，什么都没有发生，为什么？无法对数据库中的多个表数据进行排序？

这是工作前：

这里是照片选择功能代码，这个函数是在类管理：

public static function Select_Slike(){ 
     if(isset($_POST['btnsort'])) 
     { 
      if(isset($_POST['sort'])) 
      { 
       if($_POST['sort']=="cena") 
       { 
        $query = "(select * from slike order by cena desc) 
         union all 
         (select * from en_slike order by cena desc) 
         union all 
         (select * from ger_slike order by cena desc) 
         "; 

        $rez = mysql_query($query); 
        while($row = mysql_fetch_array($rez)) 
        { 
         echo '<div id="block1"><h5 id="naslov">'.$row['naslov'].'</h5><h5 id="cena">'.$row['cena'].'</h5><img src="images/'.$row['string'].'.jpg" class="slike"/><h5 id="materijal">'.$row['materijal'].'</h5><h5 id="dimenzije">'.$row['dimenzije'].'</h5></div>'; 
        } 
       } 
       else 
       { 
        $query = "(select * from slike order by slike_id desc) 
           union all 
           (select * from en_slike order by slike_id desc) 
           union all 
           (select * from ger_slike order by slike_id desc) 
           "; 

        $rez = mysql_query($query); 
        while($row = mysql_fetch_array($rez)) 
        { 
         echo '<div id="block1"><h5 id="naslov">'.$row['naslov'].'</h5><h5 id="cena">'.$row['cena'].'</h5><img src="images/'.$row['string'].'.jpg" class="slike"/><h5 id="materijal">'.$row['materijal'].'</h5><h5 id="dimenzije">'.$row['dimenzije'].'</h5></div>'; 
        } 
       } 
      } 
     } 
     else 
     { 
      $query = "(select * from slike order by slike_id desc) 
         union all 
         (select * from en_slike order by slike_id desc) 
         union all 
         (select * from ger_slike order by slike_id desc) 
         "; 

      $rez = mysql_query($query); 

      while ($row = mysql_fetch_array($rez)) 
      { 
       echo '<div id="block1"><h5 id="naslov">'.$row['naslov'].'</h5><h5 id="cena">'.$row['cena'].'</h5><img src="images/'.$row['string'].'.jpg" class="slike"/><h5 id="materijal">'.$row['materijal'].'</h5><h5 id="dimenzije">'.$row['dimenzije'].'</h5></div>'; 
      } 
     } 
    }

，这是身体的PHP/HTML代码：

<body> 
    <form action="" method="post"> 
    <div id="sortiranje"> 
     <select name="sort"> 
      <option value="date">Datum</option> 
      <option value="cena">Cena</option> 
     </select><input type="submit" name="btnsort" value="sort"/> 
    </div> 
    </form> 
    <div id="slike_blok"> 
    <?php 
    try{ 
    Manage::Select_Slike(); 
    } 
    catch(Exception $e){ 
     die("<center><font size='42' color='red' weight='100'>SERVER DATABASE ERROR! ".$e->Message()."</font><center>"); 
    } 
    ?> 
    </div> 
</body>

为什么不添加一个语言列到你的slike表，而不是使用三个表？ – 2013-05-10 14:54:56

@MarkBaker对，很好的提醒我，我有一个专栏“jezik”（语言），我现在继续这个项目3个月后，我忘了我有列omg。谢谢。 – user1814358 2013-05-10 15:15:04

请尝试像这样的顺序应该是所有工会结束

public static function Select_Slike(){ 
    if(isset($_POST['btnsort'])) 
    { 
     if(isset($_POST['sort'])) 
     { 
      if($_POST['sort']=="cena") 
      { 
       $query = "(select * from slike) 
       union all 
       (select * from en_slike) 
       union all 
      (select * from ger_slike) order by cena desc"; 

$rez = mysql_query($query); 
while($row = mysql_fetch_array($rez)) 
{ 
echo '<div id="block1"><h5 id="naslov">'.$row['naslov'].'</h5><h5 id="cena">'.$row['cena'].'</h5><img src="images/'.$row['string'].'.jpg" class="slike"/><h5 id="materijal">'.$row['materijal'].'</h5><h5 id="dimenzije">'.$row['dimenzije'].'</h5></div>'; 
} 
} 
else 
{ 
$query = "(select * from slike) 
union all 
(select * from en_slike) 
union all 
(select * from ger_slike) order by slike_id desc 
"; 

$rez = mysql_query($query); 
while($row = mysql_fetch_array($rez)) 
{ 
echo '<div id="block1"><h5 id="naslov">'.$row['naslov'].'</h5><h5 id="cena">'.$row['cena'].'</h5><img src="images/'.$row['string'].'.jpg" class="slike"/><h5 id="materijal">'.$row['materijal'].'</h5><h5 id="dimenzije">'.$row['dimenzije'].'</h5></div>'; 
} 
} 
} 
} 
else 
{ 
$query = "(select * from slike) 
union all 
(select * from en_slike) 
union all 
(select * from ger_slike) order by slike_id desc 
"; 

$rez = mysql_query($query); 

while ($row = mysql_fetch_array($rez)) 
{ 
echo '<div id="block1"><h5 id="naslov">'.$row['naslov'].'</h5><h5 id="cena">'.$row['cena'].'</h5><img src="images/'.$row['string'].'.jpg" class="slike"/><h5 id="materijal">'.$row['materijal'].'</h5><h5 id="dimenzije">'.$row['dimenzije'].'</h5></div>'; 
} 
} 
}
