Store content from an html table to a mysql database

Question

All i want to do is to store the user entered values to a database.There is a table and it has many text boxes where the user enters his input.Upon clicking submit button the values should be stored in the mysql table. I'm getting some errors right now.I'm completely new to php,Below I've attached the code and screenshots.

//workingcode.php
<?php
$con = mysql_connect("localhost","tom","");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
//select Database

mysql_select_db("sms", $con);

$result = mysql_query("SELECT * FROM dept_info", $con) or die(mysql_error());

echo "<table border='1'>";
echo '<tr> <th>Sl No</th> <th>USN</th> <th>Name</th><th>code1</th><th>code 2</th> <th>code 3</th> <th>code 4</th> <th>code 5</th> 
                <th>code 6</th> <th>code 7</th> <th>code 8</th></tr>';

while($row = mysql_fetch_array( $result )) {
    // Print out the contents of each row into a table
    echo "<tr><td>";
    echo $row['id'];
    echo "</td><td>";
    echo $row['usn'];
    echo "</td><td>";
    echo $row['name'];
    echo "</td>";
    for ($i=1; $i <= 8; $i++) {
        echo "<td> <input type='text' name='sl[{$row['usn']}][$i]' size='2' /> </td>" ;
    }
    echo '</tr>';
}

echo '
<form action = "insert.php" method = "post">
<div align="bottom">
<input type = "submit" align = "BOTTOM" value = "Proceed">
</div>
</form>
';
?>

I've linked this to an insert.php file as shown below..

  <html>
<head>
<title>Marks Entry Results</title>
</head>
<body>
<h1>Student Marks Entry Results</h1>

    <?php


        $insertData = array();
foreach ($_POST['sl'] as $usn => $codes) {
    foreach ($codes as $sl) {
        $insertData[] = sprintf("('%s', %d)", mysqli_real_escape_string($usn), intval($sl));
    }
}
$con = mysql_connect("localhost","tom","");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
//select Database

mysql_select_db("sms", $con);

$query = "INSERT INTO mytable (usn, code1) VALUES\n" . join(",\n", $insertData);
$result = mysql_query($query);
if ($result) {
echo mysql_affected_rows()." Marks inserted into database.";
} else {
echo "An error has occurred. Not added.";
}
mysql_close();
?>
</body>
</html>
//The description of the table which i made for this is
/*mysql> desc mytable;

The textboxes are not inside any form tag so when you hit submit the value of textboxes doesn't get post back to server...Try following.

echo '<form action = "insert.php" method = "post">';
while($row = mysql_fetch_array( $result )) {
    // Print out the contents of each row into a table
    echo "<tr><td>";
    echo $row['id'];
    echo "</td><td>";
    echo $row['usn'];
    echo "</td><td>";
    echo $row['name'];
    echo "</td>";
    for ($i=1; $i <= 8; $i++) {
        echo "<td> <input type='text' name='sl[{$row['usn']}][$i]' size='2' /> </td>" ;
    }
    echo '</tr>';
}

echo '
<div align="bottom">
<input type = "submit" align = "BOTTOM" value = "Proceed">
</div>
</form>';




  //insert.php

<?php




    $insertData = array();
    foreach ($_POST['sl'] as $usn => $codes) {
        foreach ($codes as $sl) {
            $insertData[] = sprintf("('%s', %d)", mysqli_real_escape_string($usn), intval($sl));
        }
    }

    $con = mysql_connect("localhost","tom","");
    if (!$con) {
       die('Could not connect: ' . mysql_error());
    }
    //select Database

    mysql_select_db("sms", $con);

    $query = "INSERT INTO mytable (usn, code1) VALUES\n" . join(",\n", $insertData);
    $result = mysql_query($query);
    if ($result) {
       echo mysql_affected_rows()." Marks inserted into database.";
    } else {
    echo "An error has occurred. Not added.";
    }
    mysql_close();
    ?>
