no ive tried that - presumably the _ also has to be included in the original name (before it is POSTed) - or is that needed to make it work?

You can access the element of any array with a variable, such as:
Code: Select all
$variable = 'foo';
$counter = 42;
$key = $variable . $counter;
echo $_POST[$key];

cheers for the reply
yeah it would but what i am trying to do is use a set of linked lists that display dynamically
the linked list names are concatenated with a number - the number being the number of previous lists + 1 but on each page I need to check if that linked list has been POSTed
so the linked list would be declared like this:-
Code: Select all
${"sub_topic". $branch_count} = '<select name="sub_topic'. $branch_count.'" onChange="this.form.submit()">';
and then to check if a value from this list has been submitted i need to check the POST vars - something along the lines of
Code: Select all
if(isset($_POST['sub_topic'. $branch_count])){
...
}
but that doesn't work and ive tried all sorts of combinations of that - i would have thought this was possible but maybe not
