Subject: [PHP] Code help on a multi select list
I want to do a server side trap if a user selects more
from a mult select list then allowed. Just unsure and
didn't find any examples. Seems people rely more on
javascript these days.
So here is how I grab the array:
if ( is_array( $_REQUEST['LurkerIndustry'] ) ) { $_SESSION['l_industry']
= array_unique( array_merge( $_SESSION['l_industry'],
$_REQUEST['LurkerIndustry'] ) ); }
here is my somewhat hazy notion:
if
( is_array( $_REQUEST['LurkerIndustry'] ) ) { $_SESSION['l_industry'] =
array_unique( if $l_industry > 5
( Here I'm guess I need to redirect back to page
with and error message)
else
array_merge( $_SESSION['l_industry'], $_REQUEST['LurkerIndustry'] ) );
}
