Registering arrays as sessions??

[bjblackmore]

Hi,

I have a form, where users fill in their name * address, then there are some checkboxes, which pull their values out of a database. The number of checkboxes may vary. When a user presses submit, the details are emailed off, and they are given a confirm page, which displays their details, and choices. How do I register the values of the checkboxes? I don't want to do register_session('fullname','address','checkbox1', 'checkbox2', 'checkbox3'..etc cause if only checkbox1 is selected it will still try to register 2 & 3, and if there are more checkboxes, it might miss them off. I tried checkbox[0] but it didn't work. Also on the next page I want to display the choices, I tried
while ($checkbox[]){
echo checkbox[0];
}
but it didn't work either. Anyone know what I'd doing wrong?
Cheers
Ben

in your form you should have the checkboxes input name as "checkbox[]".

<input type="checkbox" name="checkbox[]">

and you can register them, regardless of how many are there by session_register('checkbox');

session_register('fullname','address','checkbox');

I hope im right.

Really, oh right, cheers I'll give it ago. Does it not have to be told what number the name is, so if I have 3 or 4 checkbox[] it will know which is checkbox[1],checkbox[2].

<?
session_start();
$var[0] = "foo";
$var[1] = "bar";
session_register('var');
?>

------ NEXT PAGE ------

<?
session_start();
echo $var[1];
?>

That should print "bar".
see what i mean buddy.

Yip I see what you mean. How do I parse that to a function though? i.e. I have a form, with a selection of radio buttons in it, dynamically created from a database, using a while command.
while($row=mysql_fetch_array($result))
{ echo '
<input type="radio" name="radio['. $number++ .']" size="2" maxlength="2">
}
$number is increased by 1 so I might have radio[1], radio[2], radio[3] etc.

Then I have

if ($submit) {
$worked=user_book($radio);
}

if ($worked) {
session_register('radio');
Header("Location: http://www.domain.com/confirm.php");
}

On confirm.php is..

while ($radio){
echo "$radio[0]"
}

however nothing is echoed. Any ideas why?
