It has an input field with quantity. When it submited, it takes me to another page, let's call it cart.</p> <p>The cart page has GF(name, telephone, addresses etc.). It also has a hidden field, populated dynamically. Parameter name: finalprice. I would like to populate this hidden field with a function, which has an input parameter $qty, and output $qty * $price = 1000. Like this:</p> <p><code><br /> function populate_finalprice($qty){<br /> $price = 1000;<br /> return ($qty * $price);<br /> }<br /> </code></p> <p>How should I use the add_filter or anything else GF functions, because this one is not working:</p> <p><code><br /> add_filter("gform_field_value_finalprice", "populate_finalprice", 10, 1);<br /> </code></p> <p>Thanks for any help. </p>
