I am doing something different with Product Options which isnt covered in the PDF tutorial.
On my product detail page where all the options are (some options are free and some at cost) + My options are based on either textfield, checkbox or select list. All my product options are dynamic (since I want Admin full control of which options go to which products).
Now I have learnt from the good techies of WebAssist that the eCart Object column is simply a storage place. So the trick is on my product detail page create an Implode Array., this can then be reference in the eCart Object.
I am testing it at th emoment (as Im learning all this by going along, so hopefully I am on the right track...here is some code examples)
......I would put this after the /form>
$strOptions = implode("|", $_POST['options']);
$strOptions = "";
...then in my form create arrays like this...
<input name="options" type="checkbox" ........
then in eCart Im a guessing to put options as the new column name.
Hopefully I am on the right track..I just wanted to share what I have at the moment in case it is of any help.
