我目前有一个网页，允许我使用名称，位置，电话号码和说明选项将商家添加到数据库。
因为我有时会在几个列表中将描述修改为相同，所以我想知道如何以一种选择多个列表的方式更改我的代码并添加一个描述来修改所有选择而不必修改每个企业都是单独的。
这是我目前的代码。

mysql_query("SET NAMES 'utf8'");

$img_res=mysql_query('SELECT * FROM tbl_directory WHERE d_id=\''.$_GET['directory_d_id'].'\'');
$img_row=mysql_fetch_assoc($img_res);
if($img_row['directory_image']!="")
{
unlink('images/'.$img_row['directory_image']);
unlink('images/thumb/'.$img_row['directory_image']);
}
Delete('tbl_directory','d_id='.$_GET['directory_d_id'].'');
$_SESSION['msg']="18";

exit;
}

if(isset($_GET['status_deactive_id']))

$data = array('directory_status' => '0');

答案 0 :(得分：0)
除非我误解了你的问题，否则你问的是如何一次修改数据库的多行。
$description = $_GET['description'];
$businesses = $_GET['businesses'];
mysql_query("UPDATE businesses SET description=$description WHERE name IN ($businesses);");
$businesses可能是这样的结果：
<input type="text" name="businesses" value="<?php print $current_business_being_examined_if_you_have_a_variable_like_this"><br />
<textarea name="description"><?php print $current_description_of_business;?></textarea>
商家是逗号分隔的名单。
