I tried this in the Javascript code. sel = document.Regform['Item'] var Item_List = new Array() document.Regform['Item_List[]'].value = '' for( i = 0 ; i<sel.length ; i++ ) { Item_List[i] = sel.options[i].value } document.Regform['Item_List[]'].value = Item_List The value determined by PHP when it is received is still an array containing 1 element. The individual items are delimited with a comma ",". > > -mic > > ----- Original Message ----- > From: "Grant Walters" <Grant.Walters@walters.co.nz> > To: <php-general@lists.php.net> > Sent: Friday, August 25, 2000 4:07 PM > Subject: RE: [PHP] Multiple Select And Javascript Issue - > AMMENDED TO ARRAY > QUESTION > > > > > > >> > Scenario as follows: > > > > >> > > > > > >> > SELECT with MULTIPLE options is being built by Javascript code > > > > >> that won't > > > > >> > accept a variable name like "items[]" so it fills a > > > > >> > field > > > > >> called "items". > > > > >> > > > > > >> > This is'nt too bad as I can work around it with a hidden > > > > >> > field. > > > > >> > > > > > >> > The problem is that PHP doesn't populate > HTTP_POST_VARS with the > > > entries > > > > >> > from "items" unless they are acutally selected. > > > > >> > > > > > >> > Can I get PHP to return all values from the SELECT > > > MULTIPLE variable? > > > > >> > > > > > >> Maybe this is relevant? > > > > >> http://au.php.net:81/FAQ.php/#7.14 > > > > >> > > > > > > > > > > The bit about the [] is.
