Trying to make a form to respond to "commands"

phusionsys

Hi.

I'm a total php noob, so go easy on me :p

Anyway, I'm trying to make a webpage that looks like a command prompt..

And I'm having trouble finding the info I need to get any further.. 🙁

What I'm trying to do is make a form input respond to different tekst written to it and output the rescuelt on the same page..

Something like this:
If the user writes:
List

Under the form the script would output:
item 1
item 2
item 3

Or if he writes:
Who
It would respond with:
My name is phusion. Welcome..

You can see the page I made here:
commandinput.php

Any idea how to get the a php script to respond to that?

Thanks for any replies :rolleyes:

looks nice...

okay, first close your form tag (it's just cleaner).
then: you need to re-submit the form to the php script in order to make something happen in php (probably rather via javascript than with a submit button) - just mentioning this because it is a fairly common misunderstanding.

then you'd need to define what commands are allowed, and what action should follow.

example, really simplified:

switch ($_POST['inputPrompt']){
case 'List':
    $output = "item1<br>item2<br>item3<br>\n";
    break;
case 'Who':
    $output = "My name is phusion. Welcome...<br>\n";
    break;
default:
    $output = 'Unknown command '.$_POST['inputPrompt']."<br>\n";
}

then you'd display the output (properly formatted of course) and below that the inputPrompt input field again.

next thing might be to store the previous commands and responses in a hidden input field so that php can access them and display them above the current response.

I hope this is giving you an idea.

Hey and thanks for the reply.

It works perfectly.

Expect that I couldent get $output to do anything..

But print worked nicely..
hmm..wonder what I'm doing wrong..=p

<<< Just my thought and plan 🙂

But again thanks =)
