I am new to PHP. I am aware I am using mysql*functions, but I will continue to use them for this project. I am looking guidance on how to display videos based on checkbox values inserted into my database. I have 14 checkboxes, which are named 1, 2, 3, 4, 5 etc...(which insert into eNISATID column). The name of each checkbox inserts into my 'eNISATID' (from enisatanswer) column (1-14), as well as value of 1 or 0 into 'eNISAT_watch' depending if the checkbox has been selected or not.
My first piece of code works fine and inserts into my database. Which is as follows:
<?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'];
$cb_names = array('1', '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14');
foreach ($cb_names as $cb) {
$cb_val = isset($_POST['$cb']) ? 1 : 0;
$sql = "INSERT INTO enisatanswer (user_id, eNISATID, eNISAT_watch) VALUES ('$userID', '$cb', $cb_val)";
mysql_query($sql) or die(mysql_error());
}
if($query==true)
{
echo'<script>alert("Your choices have inserted Successfully
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>';
}
}
?>

Can anyone help me with my second piece of code. I have matched eNISATID (checkbox name from enisatanswer) to eNISATID (PRIMARY KEY from enisatquestion to uniquely identify the row for a video) as a foreign key.
My table for my checkbox responses has the following structure:
eNISATanswersID(AUTO-INCREMENT)- 'user_id' (Users id who is logged on)
eNISATID(I want this to be the name of my checkbox, 1-14)eNISAT_watch(value of 1 or 0 depending if the checkbox has been selected or not)
My table for videos table has the following stucture:
-'eNISATID' (Primary Key - values 1-14) -'eNISATQuestion' (Text that forms the wording on my href) -'eNISATVideo' (URL for my video stored on my server)
** When I use a simple query to display all of the videos from my table, they display fine, but I wish to only dispay the videos relating to the checkbox selected and depending on the user_id of the logged on user. I feel that my SELECT query is the issue, can anyone advise.
Here is my code to display my videos from my enisatquestion table based on the checkbox values inserted. I have tried two different queries as shown. One is commented out with //. **
<?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 );
$userID=$_SESSION['user'];
$query = "SELECT eNISATQuestion, eNISATVideo FROM enisatquestion INNER JOIN enisatanswer WHERE enisatanswer.eNISATID = enisatquestion.eNISATID AND user_id = $userID AND eNISAT_watch = 1";
/* A default message if the query fails or there are no records */
$enisatquestion='<h2>Sorry, there are no records</h2>';
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>";
}
