Hi Robbie, I would advise against using Perl and PHP in conjunction. There should be no need to do so. Both Perl and PHP are full-scale server-side programming languages, and either language alone should have adequate facilities to handle DB processing without the complications of inter-process communications.. If you are using PHP, you probably should not need to use javascript either, since PHP has some well-developed embeds to handle data input. It also has DB coonnectivity utilities Javascript/Perl is another matter. Javascript* is a very useful, but equally limited, tool for client-side data validation. The best way to use it is sparingly. Use it to ensure that use input is sensible in the context of the data being sought--that dates are readable as dates, numerical input as numbers, phone numbers have the correct number of digits, etc. You don't really address perl directly though. Javascript interacts with the form objects on the web page, and you can use it to reset them: document.FormName.FormObject.value = CorrectedValue; then your CGI script will read the form values through the query line. Unless you have extenxsive experience with both languages, and know exactly why you need to use both in conjunction, I would recommend using either Perl or PHP, but not both, for your server-side processing. Joseph *AFAIK, there is no such thing as "Java Script". Java is a standardized, paltform-independent, strongly-typed, structured compiled and intepreted language. Javascipt is an utnyped, unstructured, interpeted language, the implementation of of which is dependent on the browser on which it is run. Java was developed at Sun Computer. Javascript seems to have been developed by Netscape, although the information I base that impression on is not at all conclusive. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
