Insert et recover personal value in Form

[thebuzzman]

Hi All,

 

I have a question which is, I think, of a too important facility so that I see it:

 

In product_info, I put a personal field in supplement:

 

 echo tep_draw_input_field (envoi);

 

I wish to recover the value of this field (Example: 212) in shopping_cart. I tested this

 

 $envoi = $_POST [envoi];
echo $envoi;

 

I do not see anything?! I know, it is certainly normal, but how to make?

 

Thank you
