list.skin.php 에서 셀렉트 박스를 하나만들 었습니다.

각 지역을 선택하면 바로 db 필드 wr_11 로 입력 받을 수 있도록 하고 싶습니다.

고수님들의 조언 부탁드립니다.

<div id="align">  
<div id="content">

<form name="fwrite" method="post" onsubmit="return fwrite_submit(this);" enctype="multipart/form-data" style="margin:0px;">

<select name="wr_11" class='ed'  itemname='지역선택' required>
?>
 <option  value="1" <? if($write[wr_11] == "1") echo "selected"; ?>>광주</option>
 <option  value="2" <? if($write[wr_11] == "2") echo "selected"; ?>>서울</option>
  <option  value="3" <? if($write[wr_11] == "3") echo "selected"; ?>>부산</option>
 <option  value="4" <? if($write[wr_11] == "4") echo "selected"; ?>>인천</option>
 <option  value="5" <? if($write[wr_11] == "5") echo "selected"; ?>>대구</option>
</select> 
 </td>

if($write [wr_11] == "1"){

 sql_query("update g4_write_stock set wr_11='광주' where wr_id='{$list[$i][wr_id]}'");
}

if($write [wr_11] == "2"){
 sql_query("update g4_write_stock set wr_11='서울' where wr_id='{$list[$i][wr_id]}'");
}

if($write[wr_11] == "3"){
 sql_query("update g4_write_stock set wr_11='부산' where wr_id='{$list[$i][wr_id]}'");
}

if($write[wr_11] == "4"){
 sql_query("update g4_write_stock set wr_11='인천' where wr_id='{$list[$i][wr_id]}'");
}
if($write[wr_11] == "5"){
 sql_query("update g4_write_stock set wr_11='대구' where wr_id='{$list[$i][wr_id]}'");
}
