m_cat_to_buy doesn't appear in your snippet of the class, so it's hard to
100% say, but there are some problems in your code that make it seem
likely that I know what you've done.

Here you correctly declare a member variable m_cat_for_free

Here you assign a passed in variable ($p_cat_for_free) to a dynamically
determined property which is not determined. An example would make this
clearer I'm sure:

You could have used

function CProductForFree($p_cat_for_free, [snip])
{
$property = "m_cat_for_free";
$this->$property = $p_cat_for_free;

But what you likely meant was:

function CProductForFree($p_cat_for_free, [snip])
{
$this->m_cat_for_free = $p_cat_for_free;

You create the member variable with "var $name" but you use it with
"$this->name" (notice no $ before name).

So, although you haven't included m_cat_to_buy in your code snippet, I'm
guessing it's the same problem as this.

Hope this helps.

Cheers,


Andy
