you should always initialize your variables before use, That is the meaning of your eror, Do you have any undefined variable.? Its there on the Line number of your Error report.

Hi there,
when you sending the hidden form fields, there is no value with them.Try to send them too
This will work for you.

Expand|Select|Wrap|Line Numbers

 
<input type="hidden" name="productid" value="<?Php echo $r['productid'];?>"/>

<input type="hidden" name="price" value="<?Php echo $r['price'];?>"/>

<input type="hidden" name="productname" value="<?Php echo $r['productname'];?>"/>

Post back with your updates. Thanks :)

You have to put the hidden parameters to the form. That form is the one which calling for the php script to process the form data, additionally now you getting the error from the called script. as undefined index. So first put the values to the calling script.Then post it.
You should replace the line number 36,37,38 on this post.

Notice: Undefined index: productid in d:\inetpub\wwwroot\lucyclewis\basket.php on line 23

Notice: Undefined index: price in d:\inetpub\wwwroot\lucyclewis\basket.php on line 24

Notice: Undefined index: productname in d:\inetpub\wwwroot\lucyclewis\basket.php on line 25

Where is the <hidden> fields? Still Its not there in the above post. you have to add them inside the FORM on the first code listening.

Please use the code tags in this format.
[code=php]
and
make sure to close them as described in the reply Guidelines on the right hand side with your text editor.
