Answer 1

添加這在while循環

在如果condtion循環添加所選擇的選項名稱或值，並定義一個vaiable有

$selectedval = $f3['teenus']; 

編輯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>'; 

添加這可變的地方持有人

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