숫자값입력

wirte_skin.php

​

<tr>
            <th scope="row"><label for="wr_good">주문수량<strong class="sound_only">필수</strong></label></th>
            <td><input type="text" name="wr_good" value="<?php echo $wr_good ?>" id="wr_good" class="frm_input" size="20" maxlength="20"></td>
        </tr>

view_skin.php

 <li>주문수량 : <?php echo $view['wr_good'] ?><span>|</span></li>

요렇게입력을하는데 글쓰기폼에서 입력을하면 db에도 0으로박히고 주문수량에도 0으로 박히는데..이유가뭘까요..
