Sorry but, I am reopening this, because I need to change some parameters on 
the client form before I can add it to the database.

I have a 2 fields database key:

cat_id (foreign key from table categories)
pro_id 

In the table are some values:

cat_id  pro_id  pro_name
1               1               product1
1               2               product2
2               1               product3
2               2               product4

I need to let the user select the product from a HTML page in a combo basis. 
Then i can code:

<select name="my_product">
        <option value="1-1">product1</option>
        <option value="1-2">product2</option>
        <option value="2-1">product3</option>
        <option value="2-2">product4</option>
</select>

When the user send the request I get a parameter my_product="x-y". Where x is 
the encoded value of cat_id and y is the value of pro_id.

Now my problem comes to life: How to create new request parameters into an 
action to make 2 new parameters:

cat_id="x" and pro_id="y"

Please help me ;)

Antonio Gallardo.
