如何從多個複選框中獲取值並插入到數據庫中？

Question

我正在使用複選框接受多個值的特定窗體上工作，我發現很難獲取檢查框的所有值並將它們存儲到數據庫中。

每當正在執行我的插入查詢..存儲在數據庫中的唯一價值是最後的複選框，這樣用戶選擇忽略其他..

這裏是我的代碼：

--- -形成 - - - - - - - - - - - - - - - - - - - - - - - - -----------------'

<form name="addRes" method="post" action="addReservation_code.php"> 
<table> 
    <tr><td>Activity Date:</td> 
    <td><select name="month"> 
    <option value="January">January</option>

     include 'RRSdbconnect.php'; 
     $query = "SELECT room_name from room"; 
     $result=mysql_query($query) or die('Invalid query'.mysql_error()); 
     while ($row = mysql_fetch_array($result, MYSQL_BOTH)) 
     { 
      echo "<option>$row[room_name]"; 
     } 
     ?> 
     </option> 
    </select> 
    </td> 
    </tr> 
    <tr>

------------ action code ----------- -----------------------------------------

<?php 
include 'RRSdbconnect.php'; 
session_start(); 


$date = $_POST['month'] . ' ' .$_POST['day']. '-' .$_POST['day2']. ', ' . $_POST['year'] ;

//insertions for add reservations 
$query="insert into reservation (activity_date, activity_name, activity_time, room, resources_needed, no_person, reserved_by) values('$date','$name','$time','$room','$resources','$noOfPerson','$reservedby')"; 
$result=mysql_query($query,$link) or die("Error!".mysql_error()); 
?>

如果更改複選框的name屬性name="resources[]"你應該在$_POST['resources']

數組

一旦你在$_POST['resources']有數組，你可以在數據庫中存儲/檢索你喜歡的數組。例如作爲使用implode()/explode()或serialize()/unserialize()的字符串。
