創建下拉菜單和描述更改

Question

我目前有一個網頁，允許我通過名稱，位置，電話號碼和描述選項將業務添加到數據庫。

因為有時我會將多個清單上的描述修改為相同，所以我想知道如何更改我的代碼，以便選擇多個清單並添加一個描述，該描述將修改所有選定列表，而不必分別修改每個業務。

這是我當前的代碼。

<?php include('includes/header.php');?>


<?php include('includes/menu.php');?>

<?php 
    include('includes/function.php');
    include('language/language.php');  

    mysql_query("SET NAMES 'utf8'");    


    if(isset($_GET['directory_d_id']))
    {

        $img_res=mysql_query('SELECT * FROM tbl_directory WHERE d_id=\''.$_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";
         header( "Location:manage_directory");
         exit;
    }

    //Active and Deactive status
    if(isset($_GET['status_deactive_id']))
    {
        $data = array('directory_status'  =>  '0');

        $edit_status=Update('tbl_directory', $data, "WHERE h_id = '".$_GET['status_deactive_id']."'");

Answer 1

除非我誤解了您的問題，否則您是在問如何一次修改數據庫的多行。

$description = $_GET['description'];
$businesses = $_GET['businesses'];
mysql_query("UPDATE businesses SET description=$description WHERE name IN ($businesses);");

$businesses可能是由於以下原因導致的：

<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>

企業是用逗號分隔的名稱列表。
