Hey Guys,

 

    I am having trouble, I am working on an assignment is basically an online store that sells CDs. Now I am trying to add items to the Cart but getting is weird error "Object Id #2", see below for the code and yes I know its very messy code at the moment but im just testing with it.

 

<?php

$DBConnect=@mysqli_connect("localhost", "username", "password", "database")
    Or die("<p>Unable to connect to the database server.</p>" . "<p>Error code " . mysqli_connect_errno($DBConnect) . ":" . mysqli_connect_error($DBConnect)) . "</p>";

$TableName="cart";
$CdId = "$_GET[cdid]";
$CdNamestring = "SELECT cd_name FROM CDs WHERE cd_id='$CdId'";
$CdName = mysqli_query($DBConnect, $CdNamestring);
$ItemQtystring = "SELECT item_qty FROM cart WHERE cd_id='$CdId'";
$ItemQty = mysqli_query($DBConnect, $ItemQtystring);
$TotalQty = $ItemQty + 1;
$Pricestring = "SELECT cd_price FROM CDs WHERE cd_id='$CdId'";
$Price = mysqli_query($DBConnect, $Pricestring);
$CurrentTotalPricestring = "SELECT total_price FROM cart WHERE cd_id='$CdId'";
$CurrentTotalPrice = mysqli_query($DBConnect, $CurrentTotalPricestring);
$TotalPrice = $Price + $CurrentTotalPrice;

echo "Table: '$TableName' cd_id: '$CdId' CD Name: $CdName ItemQty: '$ItemQty' TotalQty: '$TotalQty' Price: '$Price' Current Total: '$CurrentTotalPrice' TOTAL:'$TotalPrice'";

$SQLstring = "INSERT INTO $TableName VALUES ('','','$CdName','$TotalQty','$TotalPrice')";
$QueryResult=mysqli_query($DBConnect, $SQLstring)
Or die("<p>Unable to execute the query.</p>" . "<p>Error code " . mysqli_connect_errno($DBConnect) . ":" . mysqli_connect_error($DBConnect)) . "</p>" .
'<a href="admin.html">Return to Delete.php page</a>';
echo "<p>Successfully Added to Cart</p>";	
echo '<a href="main.php">Return CD Selection</a>';
mysqli_close($DBConnect);  

?>

 

Im echoing all the variables to the screen to see what they are and this is the output:

 

Table: 'cart' cd_id: '2' CD Name: Object id #2 ItemQty: 'Object id #3' TotalQty: '2' Price: 'Object id #4' Current Total: 'Object id #5' TOTAL:'2'

 

 

Please let me know if you need more information.

OK... you got it all wrong

 

MySQLi is used like this:

 

$qry = "SELECT cd_name, item_qty, cd_price FROM CDs WHERE cd_id='$CdId'";
$result = mysqli_query($DBConnect, $Pricestring);
$row = mysqli_fetch_assoc($result);

var_dump($row); //this will show an array with data
