查询以显示表中与其他表

标签： php mysql video checkbox

我需要有关我无法实现的查询的帮助。我知道不推荐使用mysql函数，但我的网站只是一个原型，因此对于这个项目来说并不重要。

我有一个网站，用于为用户显示视频教程以进行培训。向用户显示带有复选框的14个问题的列表，他们可以勾选相关的复选框并在下一页上查看每个相关的教程。

登录人员的user_id也会插入到我的数据库中，以便我可以识别谁选中了复选框，以及每个复选框值（1或0）到我的答案表（enisatanswer）中的单独列中。这是我的插入代码，工作正常。一开始的SELECT语句是维护用户的SESSION详细信息，并在每个页面中使用。

<?php  
session_start();
include_once 'dbconnect.php';

if(!isset($_SESSION['user']))
{
 header("Location: index.php");
}
$res=mysql_query("SELECT * FROM users WHERE user_id=".$_SESSION['user']);
$userRow=mysql_fetch_array($res);

if(isset($_POST['submit']))
{  
header("Location: eNISATVids.php");

@$userID=$_SESSION['user'];
@$checkbox1=$_POST['Log'];
@$checkbox2=$_POST['Worktray'];
@$checkbox3=$_POST['Visual'];
@$checkbox4=$_POST['ChangePd']; 
@$checkbox5=$_POST['Logout'];
@$checkbox6=$_POST['ClientSearch'];
@$checkbox7=$_POST['StartAssessment'];
@$checkbox8=$_POST['Finalise'];
@$checkbox9=$_POST['Print'];
@$checkbox10=$_POST['Hcn'];
@$checkbox11=$_POST['Lcid'];
@$checkbox12=$_POST['Soscare'];
@$checkbox13=$_POST['Reassign'];
@$checkbox14=$_POST['Close'];

    $query="INSERT INTO enisatanswer (user_id,Log,Worktray,Visual,ChangePd,Logout,ClientSearch,StartAssessment,Finalise,Print,Hcn,Lcid,Soscare,Reassign,Close) VALUES 
    ('$userID', '$checkbox1', '$checkbox2','$checkbox3', '$checkbox4', '$checkbox5', '$checkbox6','$checkbox7', '$checkbox8','$checkbox9', '$checkbox10','$checkbox11', '$checkbox12', '$checkbox13', '$checkbox14')";  
    mysql_query($query) or die (mysql_error() );
if($query==true)
   {  
      echo'<script>alert("Your choices have inserted Successfully \n \n Please click on Display eNISAT Tutorials at the buttom of the page to view your videos ")</script>';  
   }  
else  
   {  
      echo'<script>alert("Failed To Insert")</script>';  
   }  
}  
?>

我目前的下一页显示了我的问题表'enisatquestion'中所有14个视频的表格中的链接。

我的问题是，任何人都可以帮我查询，只显示用户选中的复选框的视频链接，而不是全部。我猜测为了做到这一点，需要为我的'enisatanswer'表中的每一列创建一个变量。我的专栏是（日志，工作台，视觉等）

所以我认为我的查询是这样的：

SELECT * FROM enisatquestion WHERE enisatanswer (Log,Worktray,Visual....) VALUES =1 and user_id = $userID=$_SESSION['user'];

我真的不确定这个声明

非常感谢任何帮助。这是我显示视频的代码

<?php  

    session_start();
    include_once 'dbconnect.php';

    if( !isset( $_SESSION['user'] ) ) header("Location: index.php");

    $res=mysql_query("SELECT * FROM users WHERE user_id=".$_SESSION['user']);
    $userRow=mysql_fetch_array( $res );

    $query = "SELECT eNISATQuestion, eNISATVideo FROM enisatquestion";

    $result = mysql_query( $query );
    /* A default message if the query fails or there are no records */
    $enisatquestion='<h2>Sorry, there are no records</h2>';


    /* you cannot output content outside the html tags, not valid ~ it will work but NO */
    if( $result ) {/* if there is a recordset, proceed and generate html table */
        $enisatquestion = "<table >";
        while ( $row = mysql_fetch_assoc($result) ) {
            $enisatquestion .= "<tr><td><a href='{$row['eNISATVideo']}'>{$row['eNISATQuestion']}</a></td></tr>";
        }
        $enisatquestion .= "</table>";    
    }
?>
