I want to process information submitted by a form, but I want to clean up
the info before I use it. I have about 40 form fields, of several field
types. If I only had a few form fields, I would do ths manually, but since
I have so many my code will be much neater to do it with a function. I want
to loop through all the POST vars and do a strip_tags() and trim() on each
one.
Is this how I should be doing this? The code below works how I want it to.
However, I would prefer, for performance/memory issues to not perform this
on unneeded fields, such as radio buttons and select boxes where the
information is already formatted how I want. Is there any way to only
perform this on text boxes and textarea fields? THanks!
foreach ( $HTTP_POST_VARS as $key=>$value )
{
$value=strip_tags($value);
$value=trim($value);
// for debugging use only print all the variables from web form
print "$key = $value<br />";
}
