PHP MSQL FORM Query Won't Connect

Question

Hey guys I've been trying to do a code where I submit a form from a PHP Order Page so that it can update the MySQL Database with the required information

I've got the Order PHP Code Here:

<form action="http://zim.cs.uow.edu.au/~ga420/order.php" method="post">
    <tr>
        <th>Shirts</th>
        <th>Quantity</th>
    </tr>
    <tr>
        <td>
            <br />
            <input type="checkbox" name="items" value="SH01" />
            <label for="rd1">Obey T-Shirt: $9.99</label>

<?php

if (isset($_POST['submit'])){

    $conn = mysql_connect('url','username','password');
    if (!$con){
        die("Could Not Connect: " . mysql_error());
    }

    mysql_select_db("db",$conn);

    $sql = "INSERT INTO Order_Information(Order_ID,Order_Items,Order_Quantity) VALUES (null,$_POST[items]','$_POST[qty]')";

    mysql_query($sql, $con);

mysql_close($con);
}

?>

Obviously my username and password I won't display but when I hit the submit button it says that it cannot connect.

You can try the form yourself on this website: http://zim.cs.uow.edu.au/~ga420/order.php

How come it is saying that I can't connect when clearly I have been putting the right details in.

Can anyone help? this has been stressing me out :'(

Your help is appreciated greatly!!

Answer 1

You need to serialize all your inputs/quantities if you will have the same name "qty" in all fields. I will update my answer later if you do t get answer about this.

You had also small bugs on your code, notice this:

VALUES (null,'$_POST[items]','$_POST[qty]')"; - you were missing ' before $_POST[items]

$conn = mysql_connect('zim.cs.uow.edu.au','username','password'); - $conn with 2 "n"

So, a corrected version would be:

<?php

if (isset($_POST['submit'])){

$con = mysql_connect('url','username','password');
if (!$con){
    die("Could Not Connect: " . mysql_error());
}

mysql_select_db("db",$con);

$sql = "INSERT INTO Order_Information(Order_ID,Order_Items,Order_Quantity) VALUES (null,'$_POST[items]','$_POST[qty]')";

mysql_query($sql, $con);

mysql_close($con);
}

?>

Answer 2

Change to this. You did some mistake on $conn and $con. Then, '$_POST[items]','$_POST[qty]' in query.

if (isset($_POST['submit'])){

$conn = mysql_connect('url','username','password');
if (!$conn){
    die("Could Not Connect: " . mysql_error());
}

mysql_select_db("db",$conn);

$sql = "INSERT INTO Order_Information(Order_ID,Order_Items,Order_Quantity) VALUES      (null,'$_POST[items]','$_POST[qty]')";

mysql_query($sql, $conn);

mysql_close($conn);
}

Hope this help
