Display other products of the same category in product detail view?

[syg7]

Hello,

short and simple: underneath the "normal" product detail view, I wanna place all the other products of the same category, like in the category view. But I do not know how to make this possible.
The category/default.php contains the code for displaying all the products, beginning at row  196 (//Start the output). I wanna have the exact same effect in my product detail view. Copy and paste the code is not possible haha... I would be really grateful if somebody could help me


Thanks
