Hi,
We previously had a script called grab_globals.lib.php, which created global variables from a few superglobals arrays.
When this script was removed a few weeks ago, we added at the beginning of other scripts some code, for example in tbl_change.php:
if (isset($_REQUEST['where_clause'])) { $where_clause = $_REQUEST['where_clause']; }
In the upcoming refactoring efforts, we should avoid this, because, looking at the code further in the script, it's difficult to see the origin of $where_clause. So, we should only refer to $_REQUEST['where_clause'] (except in the situations where the global is modified afterwards).
Another benefit is that this variable would not need to be passed as a parameter to functions.
Hi Marc, Thank you very much for pointing out.
Hi Marc, when I write functions for columns(function column, null column, value column, ...) in insert form (line 408 in tbl_change.php) I have to pass lot of parameters. But it is not a good practice for refactoring. And use global variables also not a good solution. So is it ok to use a parameter array. I need to pass around 10 parameters. I like to see your suggestions.
10 is not nice but I think it's more readable, if you have to pass these 10 arguments two or three times it shouldn't be too troublesome. If you don't like it, maybe create a special object type that you will pass around? But not a stdObject, a custom one so that parameters will be properly documented and you will get code assist in some smart editors (just a suggestion).
