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

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
