Adding values to an array

[Anon]

I have a page with a Form that submits to $PHP_SELF, and I want variables to be put inside of an array, now, thats easy. Heres the part I dont get,
the page pulls up new data (from a database) and when I click submit, the data gets into the array, but the data that was currently in the array is gone.

Any ideas, suggestions, help is greatly appreciative.

Could you post the relevant parts of your code?

Sure. Here ya go:

if(!isset($val_array))
$val_array= array();
$val_array[$categoryname] = $$categoryname;
print "<BR><B>Array Stuff</B>";
for(reset($val_array); $key = key($val_array); next($val_array))
{
print "$key : $val_array[$key]";
}

yeah, the variable variables scare me.

Anyways, when I click submit i (think it clears the array and adds the new value, not just adding it on to the end.

Well, I don't see the submit button, but if I perhaps read
between the lines you're expecting the contents of the
array to stay there between invocations of the script?
That can't happen; you need to either send the entire
contents of the array as part of the form (as hidden
inputs, most likely) or else save them in the database
or as session variables.

Which would you do personally, Use a hidden input field or session variables? (do session variables require cookies?)
