I have created a dropdown, and I want to pass the value that's selected to a hidden field when it's submitted.
Basically the form is used for submitted an advert, the dropdown is the number of images they require in the ad (options are 1-5), and the more images they submit, the higher they need to be in the listings. The dropdown is also a pricing field, which passes the value to the total. I just need to pass the dropdowns value to a hidden custom field, which is used to order the posts on the output page.
Can anyone offer some advice on what I need to do?
