[SOLVED] Pass values of Select Multiple to Hidden input

[Daniel St. Jules]

Hey all,

I'm hoping someone may assist me in this matter.

 

I have a form, and the form contains a select field with multiple="multiple", and a hidden field. I'd like to have the contents of the select, upon change, be added to the hidden field. To separate the different values of the select options in the hidden field, I'd like to use spaces. So, an example of the result would be:

 

Select

option 1 value = 20

option 2 value = 40

option 3 value = 50

option 5 value = 200

 

And, if option 1 and 5 were selected, then the value of the hidden field would look like this:

 

20 200

 

Any ideas as to how I could accomplish this? Any and all help would be greatly appreciated!

Thanks.

Well, you've already marked the topic as solved, but I have to ask. If you already have a select field that allows multiple inputs, why do you need to populate the selected values into a hidden field?
