Answer 1

在while循环中添加此内容

在condtion循环中添加所选的选项名称或值，并在那里定义一个可变的

$selectedval = $f3['teenus'];

编辑2

$selectedval = '';
while ($f3=mysql_fetch_assoc($q3)) { 
      $klient=$f3['klient']; 
      if ($f3['id']==$klient) { $selected = "selected"; $selectedval .= $f3['teenus'];  }  //add it here
      echo '<option value="'.$f3['id'].'" $selected>'.$f3['vnimi'].'-'.$f3['teenus'].'</option>';
    }

    echo '</select>';

将此变量添加到占位符

<input type="text" name="kogus" placeholder="<?php echo $selectedval ;  ?>">

我怎么能选择在占位符中使用所选名称？
