 hello php developers!

i've come across a rather debatable behaviour of PHP getting array variables from a form.

let's have a html form with multiple selection list:

form.html:
<html>
<body>
  <form name='aform' method="post" action="process_form.php3">
    <select name="n_sas"size=10 MULTIPLE>
      <option value=1>option 1</option>
      <option value=2>option 2</option>
      <option value=3>etc.</option>
    </select>
  </form>
</body>
</html>

the php3 file could then be:

process_form.php3:
<?
	echo "number of elements in n_sas is " . count($n_sas) . "<br>\n";
?>

this will print 1 ($n_sas is not an array according to php).
okay, so i change the name of the variable in the form.html file to 'n_sas[]':

...
<select name="n_sas[]" size=5 MULTIPLE>
...

in this case php will consider $n_sas as an array and all its items will be accessible. all is fine, BUT:
 'document.aform.n_sas[]' is NOT accessible from javascript!

if the name is 'n_sas', obviously the selection list is accessible from the javascript (via document.aform.n_sas) but PHP won't make it an array and the variable $n_sas will have the value of the last selected option. IMO, that's not a correct behaviour.

	thanks for your time,

		Michal

This is a FAQ - use the form elements numerical index instead of the full element name from Javascript.

Michal - try putting a space in name="n_sas"size=10
