select boxes POST

@tripwaterMar 31.2003

I have a select box that gets filled from a DB query and contains a list of email addresses. I allow the user to multi select email addresses and by way of javascript move the selected email addresses over to another select box.

Now once they have their selected group of email addresses in the second box they hit submit and I process these email addresses. This is what I want.

So how do I access these email addresses on the next page? I need all of the addresses from the second box that they moved over. I am using php on the server side and using the post method on the form.

Thank you for your time.

@tripwaterauthorApr 01.2003 — #I assume I just loop through the count of objects and set each to selected?

Once that happens do I access the array through POST_VARS on the next page?

@tripwaterauthorApr 01.2003 — #I am new to Javascript and I think I am going to need some help with that function to loop through the select box I tried what I thought would work in the function call White() below is my code . There is php and mysql mixed in so ignore that.

Thanks ahead of time.

@tripwaterauthorApr 01.2003 — #Hello? did I ask a stupid question? Where did eveyone go?

@tripwaterauthorApr 02.2003 — #Thanks for the reply and the direction. I am having the same problem that Lily was as when I manually select all of the addresses in the list and hit submit just to see what is passed over (I am using php server side) my POST_VARS ,which handles form elements as posted variables to the next page, only echos one email address even after I have manually selected all of them on the previous page. I also tried this on the submit page :

$temp = explode("n",$HTTP_POST_VARS["towhite"]);

foreach ($temp as $value)
   {
   echo $value;
   }

"towhite" is my editbox name.

someone suggested I try this to explode the new line character and set the remaining element into an array and echo the results. This resulted in the same...one email address.

I understand everything needs to be selected in the list but my problem is php has a function called print_r(get_defined_vars()); which prints all defined and set variables to the screen and in which I can search for what is holding this comma separated array but after manually selecting and submitting...again I can only find one email address in the list. I do not know what to do. I have this question in a php forum as well and so far no good.

Thank you again for your time.
