Hi Group,



How can I control I/O from a web browser?



I though I can do it like this.


1) Apache for web server
2) PHP and mySQL
3) Create a data base fields for data I want to pass from browser
4) Write to the data base filed via web page using php or Java applet
5) Read the variables from the database fields with C/C++ program which talks I/O ports


Can any one point me any link I can look at or any better ideas???????????????????



Tnx

Hi Rushi,

What kind of IO?

Or some other small server which implem ents the cgi.

OOps. Seems a little bit oversized to me.

Why not reading the ports directly and access them via cgi?

The book at

(chapter 12) has an example of what you're talking about. Basically, you write a simple device driver and then call it via cgi.

Take a look at Run Time Access. It makes variables and arrays of structs in a running program look like tables in a PostgreSQL DB. RTA has both read and write callbacks (umm, "triggers" in DB-speak) so what you want would be really easy.

See the web site:

and its live demo:

Or look at the most recent issue of LinuxFocus webzine:
