You could be using "variable variables" to do that, but for checkboxes, it's
way more better to use arrays:
<INPUT TYPE=CHECKBOX NAME=checkbox[1] VALUE=42>
<INPUT TYPE=CHECKBOX NAME=checkbox[2] VALUE='Life, the Universe, and
Everything'>
Now your processing page can just iterate through $checkbox:
while (list($key, $value) = each($checkbox)){
echo "$key -- $value was checked<BR>\n";
}
Only thing to watch out for -- If nothing is checked, $checkbox won't be an
array, and each() will give an error message.
So add this above that:
if (!isset($checkbox)){
$checkbox = array();
}
This checkbox/array stuff is in the FAQ, so read that http://php.net/FAQ.php
and the "variable variables" is in the online manual also.
