How to kick off another PHP script...

Mister_Internet

All,

I'm fairly new to PHP, but not to programming... I understand the whole "stripping a cmd ID off of a URL" thing, but here's what I'm trying to do... I'm trying to write a psuedo-command-pattern framework for this little site I'm working on that are entirely database driven functions.

There will be strictly viewing, editing, modifying, updating, and other stuff like that... what I want to do is have the "...?cmd=0" in the URL get pulled off of $_GET['cmd'] and assigned to $cmd. Then, run a switch statement on $cmd and compare to the command IDs... 0, 1, 2, etc etc. Here's the thing... I'm thinking of writing the functionality for each type of cmd (let's say "0" is the "view" command) in separate PHP scripts. That way, if "cmd=0" in the URL, the switch statement switch($cmd) compares case 0: .... Anyway, say I want "0" to be "view", and I write a script to handle all static "view-only functionality" called "view.php". How can I redirect to the "view.php" functionality from the switch case? Do i have to include, or can I effectvely "Send over" to the other script and let it take over?

Hope you understand what I'm trying to say... thanks!

Hi Tom

I'd be inclined to have a very basic script at the top level which just does this

<?php
switch ($cmd)
{
  case 0:
    include view.php;
    break;
  case 1:
    include edit.php;
    break;
  case 2:
    include delete.php;
    break;
}
?>

The variables posted are available to the included files and only one of these will be run. This makes this script very simple and easy to read. You then know that view.php etc hold all the key information about the task they need to do.

The only thing I might also do in this script is include a config.inc file (constants) and a startup.inc file (initialise database objects, template objects etc) so that view.php etc don't have to. Ensures they are created consistently.

Ok, that makes sense... I guess it just didn't register that "include and evaluate" actually meant it would run the friggin' thing... 😉

I've got PEAR and SMARTY already fully installed, configured, and running correctly, so I'll use those for DB, templates, etc etc... I was just curious how to work this little piece out...

Thanks a bunch!
