将多个复选框插入表中的两列

UPDATE - I have updated my question and added my code. I know mysql* functions are deprecated in version 7 of PHP I am running version 5.5. I wish to continue using these functions. My code at present inserts my 14 checkboxes into a seperate column for each (exlcuding my userID which stores the logged on users ID). I want to be able to insert the name of my checkbox into my eNISATID column and the value of my checkbox (1 or 0) into my eNISAT_watch column, along with the users ID from the session.

I am new to PHP. I am looking guidance on how to insert two values for each checkbox into my table in a seperate row. I have 14 checkboxes, which I wish to name 1, 2, 3, 4, 5 etc...(which will insert into eNISATID column). I want each name of the checkbox to insert into my 'eNISATID' column (1-14), as well as value of 1 or 0 into 'eNISAT_watch' depending if the checkbox has been selected or not.

My table 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 or 1 or 0 depending if the checkbox has been selected or not)

Can anyone help on how best to approach this?

Thank you

UPDATE - Can anyone help me with my second query. 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.

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 ON eNISATID = eNISATID WHERE user_id = $_SESSION['user'] AND eNISAT_watch = 1";
    $query = "SELECT eNISATQuestion, eNISATVideo FROM enisatquestion, enisatanswer.eNISATID = enisatquestion.eNISATID AND user_id = $userID";
    $result = mysql_query( $query );
    /* 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>";    
    }
?>

    Use an array containing the names of all the checkboxes. Loop over the names, and test whether the corresponding checkbox was submitted or not (only checked boxes are submitted).

    $cb_names = array('Log', 'Worktray', 'Visual', ...);
    foreach ($cb_names as $cb) {
        $cb_val = isset($_POST[$cb]) ? 1 : 0;
        $sql = "INSERT INTO tableName (user_id, eNISATID, eNISAT_watch)
                VALUES ('$userID', '$cb', $cb_val)";
        mysql_query($sql) or die(mysql_error());
    }
