I think it is possible to have php script that works like this:

Domain/switch.php?switch=on (or switch=true or switch=1)
Domain/switch.php?switch=off (or switch=false or switch=0)
And then when you do a getpage, on Domain/switch.php it will give you the state of the switch in text format.
How would you do this?

Thank you for your time, I have my ideas on this, but I am not that good at php and don't know where to start. The last thing i've made in php(with somebody else -.-) is like waaaay to long ago.

stores value after the = in the php variable $_GET['var_name']

ie moo.php?wat=3 => $_GET['wat'] holding value 3.
For multiple ones, separated by &
ie moo.php?wat=3&who=me

$_GET[switch] or something very similar if i remember correctly.

it comes as a variable from the GET method

edit: ninjaed

but, if you did

getpage(website.com/wat.php?switch=on);

although the switch was off, wouldnt that not work?

Do you mean something that if parametre switch equals On or 1, it'll display the text "On", and same but reverse for "Off"?

If so, then you can do something like:
[php]
<?php
$switch = strtolower($_GET['switch']);
if(($switch == 'on') || ($switch == '1'))
echo "On" else
if(($switch == 'off') || (isnumeric($switch)))
echo "Off" else
echo "Invalid value";
?>[/php]

Neither of all the previous codes posted save the status of the switch, so every time you visit the page, $_GET['switch'] will be blank.

Don't you want something like:
[php]
<?php
function getStatus()
{
return file_get_contents("switch.txt");
}

function changeStatus($status)
{
if($status != "on" || $status != "1" || $status != "off" || $status != "0")
{
echo "Wrong switch input";
return false;
exit;
}
else
{
$f = file_put_contents("switch.txt", $status);
if(!$f)
{
echo "Error switching";
return false;
exit;
}
else
{
echo "Successfully switched";
return true;
}
}
}

if($_GET['switch']) //if there is any ?switch=x in the url
{
if($_GET['switch'] != getStatus()) //prevents setting the same as there already is in switch.txt
{
changeStatus($_GET['switch']); //obvious; does the actual switch
}
}
?>
[/php]

Now the file switch.txt will contain on/off/1/0
This way, or you'd have use a db.

I think he means this:
[php]<?php
$str = "Domain/switch.php?switch=on";
$strpart = explode("switch=", $str);
echo $strpart[1];
?>[/php]
This will just show everything after "switch=", and therefore the text "on".. (without the quotes ofc)

Thanks for the help I know how Get and Post variables work, I worked with them before I think Floor66 has made the thing I wanted, but everyone I really want to thank you guys for the feedback, normally I get stuff like: "Google STFU".

Thanks :).

erm, if(isset($_GET['switch'])) {} not if($_GET['switch']) {} else it won't run if you pass false or 0 or another value that breaks down to false in php.

Also thinking that it's a bit of a silly way of valid input checking, but nothing wrong with it.

Mixster is right, I guess… it isn't working correctly.
I put home.impsoft.info/s.php & home.impsoft.info/s.txt online, try it.

[php]
<?php
if(isset($_GET['s']))
{
$f = file_put_contents("s.txt", $_GET['s']);
}
echo "switch = ". file_get_contents("s.txt");
?>
[/php]

haha, :p again it isn't working fully… it gives an error with a weird sign probably a typo.

Hmm I don't see anything wrong with it. Post the error?

Warning: file_put_contents(s.txt) [function.file-put-contents]: failed to open stream: Permission denied in /home/homeimps/public_html/s.php on line 4
switch = 1

so I've got no acces to it hmmm…..
nvm will be able to fix that I guess.

You have to CHMOD the text file(s) to 777.

You have to CHMOD the text file(s) to 777.

In other words, change the permission for the text file's?

Yes, to 777. Full public and owner access: "Read, Modify, Create" (a.k.a 777).

You can do this in your FTP client, as most support it :)

EDIT: Also, i didn't realise you wanted it to save :/

Done, worked last time I tested ;)

[php]<?php
switch($page) {
default: include("home.php"); break;
case 'home': include("home.php"); break;
case 'news': include("news.php"); break;
case 'downloads': include("downloads.php"); break;
}
?>[/php]

uhm… that's not at all what he needed… and if you'd have read the thread; it's done now.

Everyone, thank you soooo much. My program works perfectly now =).
I am going to release too probably lots of fun is this.
I can now activate the program with my mobile, run it silently and let it remove itself(remove all traces)
genious.

I kinda only need a bat that waits 5 seconds and then kills the program, and deletes the program. =)
Shouldn't be to hard.
