Question

Does anyone know how to output checkboxes value in a comma separated way?
Lets assume that I have 2 checkboxes:

• <input id="filetype_photo" name="type" type="checkbox" value="photo" >
• <input id="filetype_graphic" name="type" type="checkbox" value="graphic" >

If I retrieve them with $_GET I get the following url:

• sitename.com?type=photo&type=graphic
  My goal is to get the following url if both checkboxes are selected:
• sitename.com?type=photo,graphic

I have tried using array of checkboxes renaming them to name[] and using the following function to litertae trough the results:

$type=$_GET['type'];
while (list ($key,$val) = @each ($type)) {
echo $val;
}

but this gives me the checkboxes values but does not solve the url problem. Moreover, the urls gets messed up by changing
type=photo to &type%5B%5D=photo

Any ideas?

P.S. I need to work it out server side

Use:

<input id="filetype_photo" name="type[]" type="checkbox" value="photo" >
<input id="filetype_graphic" name="type[]" type="checkbox" value="graphic" >

And your $type=$_GET['type'] will be an array.
