Download File Script based on form options

hey all!

i am making an image gallery where people can pick the details of the image that they want and then click a button and based on the values that are entered they will download a certain image

so i have this form...

6 radio buttons and a submit.

O - 72 dpi
O - 150 dpi
O - 300 dpi

O - color
O - black
O - white

(Submit)

so then the idea would be if they select 150 dpi - black then they would download that proper file, say image1_150_blk.jpg for example

i dont think it is too hard but yea i dont really know a whole lot of javascript so i could be wrong...but its a fun little project and i would sooo appreciate it if anyone has a script for this, or if you know what you would call this so i could search for it!! i would greatly appreciate ANY advice!!!

thank you thank you thank you in advance!!!

ROCK ON!!

(yes i posted this to the javascript forum but people in there are mean and despite the 22 views no one was kind enough to even reply! thanks!!!!

)

Must have missed it in the other forum, but something similar to this should work:

Code:

<script>
function do_image()
{
	if(document.forms.myform.d72.checked) { var res = 72; }
	if(document.forms.myform.d150.checked) { var res = 150; }
	if(document.forms.myform.d300.checked) { var res = 300; }

	if(document.forms.myform.c1.checked) { var color = "clr"; }
	if(document.forms.myform.c2.checked) { var color = "blk"; }
	if(document.forms.myform.c3.checked) { var color = "wht"; }

	var image_url = "myimage_" + res + "_" + color + ".jpg";
	window.location.href = image_url;
}

</script>
<!-- Then the form: !-->
<form action="#" method="get" name="myform">

   <input type="radio" name="dpi" id="d72" value="72" checked> - 72 dpi<br>
   <input type="radio" name="dpi" id="d150" value="150"> - 150 dpi<br>
   <input type="radio" name="dpi" id="d300" value="300"> - 300 dpi<br>
<br>
<br>
   <input type="radio" name="color" id="c1" value="clr" checked> - Color<br>
   <input type="radio" name="color" id="c2" value="blk"> - Black<br>
   <input type="radio" name="color" id="c3" value="wht"> - White<br>

   <input type="submit" value="download" onclick="do_image(); return false;">
</form>
