Hi Daniël, Yes, this would be useful, maybe as a standard ns_* style command, something like an ns_bind_vars.
Right now the focus is on setting up a core AOLserver team, getting AOLserver 3.5.0 fully documented, getting the current modules cleaned up/documented, getting AOLserver 4.0 released, and a few other things. When the majority of that work is done, I think we can look at improvements to the server and modules such as you've outlined below. How are your C skills? Your man page creation skills? That’s where we could use some help right now. /s. -----Original Message----- From: AOLserver Discussion [mailto:AOLSERVER@;LISTSERV.AOL.COM] On Behalf Of Daniël Mantione Sent: Monday, November 04, 2002 3:42 PM To: [EMAIL PROTECTED] Subject: [AOLSERVER] Input data verification Hello, You have propably all build a simple a html form and a script that processes the form. Now how do you verify your input data? For example, you want the user to enter a number. How do you verify on the server side that someone indeed sent a number? Usually I use the scan command, i.e.: set r [ns_conn form] set variabletxt [ns_set iget $r variable] if {[scan %d $variabletxt variable] == 0} then { ns_returnnotfound return -code return } else { ..... } Now this is quite a lot of code for such a simple check and you write it in each form again. I got a bit bored and wrote a library for it. Now it is much easier, at the start of a script I just do: bind_form_vars {mode req num} {actionurl req} {tabledef req} {index num} {action} What does this do? - A form variable "mode" is assigned to the variable "mode". The variable is required ("req") and it must be numeric ("num"). - The form variable "actionurl" is assign to the variable "actionurl" and it is required. - The same for "tabledef". - "index" is not required, if it is not present the variable "index" will be set to {}, but if it is present it should be numeric - "action" is not required Now, since it is a very basic task that allmost every AOLserver user has to do, is it perhaps an idea to make such a library part of the standard AOLserver distribution?
