PHP - Online Status

Hello,

I have a webpage that runs some php code to control electrical devices. One part of it controls outside lights. Another part controls an electric door striker. I keep expanding the functionality of it and need to change one pin of the port without affecting the others. So far I use a different port for each function but I am out of ports so I need to use the different pins of the parallel port.

I am using a linux ubuntu server.
From my php webpage I issue this command: <?php exec("/home/setSerialSignal /dev/ttyS0 0 0"); ?> which controls the lights using the serial port. I can control 2 pins but I can't check the status of them so if I make a change to one pin it cancels the other.

For another one I use the parallel port with this command: <?php exec("/home/parashell 0x378 1"); ?> which turns on pin #2 of the parallel port.

Parashell has an executable called "pin". If you type the command "pin 0x378" it will return a value for the status of the parallel port. "1" for example which tells me that pin #2 is on. Is there a way to pass this value to a php variable?

I am looking to be able to read the status of the port and make changes to just the pin I want.

Lets say pin #2 is on and I want to turn pin #3 on. I would have to issue <?php exec("/home/parashell 0x378 2"); ?> to turn pin #3 on, but that would turn off pin #2. If I could pass the "1" from the "pin" command I could add it to the "2" and give it the command with a variable as "3".

Thanks in advance for any help you can give. I hope I explained it ok and didn't confuse everyone.

I am wanting to echo one of these 4 statements depending on the 'status' value. Currently it is showing the status value on the 2nd line but not the statement below..

Code: [Select]
<li>
<strong>Status: </strong><?php more_fields('status') ?>

<?php if (more_fields('status')=="Red") echo "Your account is currently undergoing judgement";
elseif (more_fields('status')=="Green") echo "Your account is currently Live"; 
elseif (more_fields('status')=="Yellow") echo "Your account is currently undergoing site visits";
elseif (more_fields('status')=="Blue") echo "Your account is currently undergoing insolvency/liquidation";?>

</li>

any help appreciated.

I'm trying to figure out to get a file to call a page on another domain(diffrent server) and check if the activation code matches the one on the activation server.

So on the user's server it has a cron job or on load will call my server and run the code in their update.php file against my activation.php file and see if it matches.

If($usr == $actv){
     //DO THIS
}else{
     //run disable script
}

Hello,

I am trying to figure out how to grab the latest aim status update from "http://lifestream.aol.com/stream/iragedxt"

But I can only see the Current Status if I am logged into my aim account on the website so is there a way I can log into my aim account on lifestream.aol.com and then I believe its to use curl to grab the text from the other website?

if so could someone please help me with this?

Thanks,
John

I am trying to make a Server Status checker that uses a image to tell if it is online or not. I also am trying to make it so you can the URL as a image code(EX: http://Http://domain.com/statuscheck.php?ip=google.com&port=80). What I'm trying to say it, that if you do like <img src="http://Http://domain.com/statuscheck.php?ip=google.com&port=80"> it would go to my site, use the php script, and then have the image Online or Offline, were the <img> code was posted.

Here's my code Im trying to make it from.
<?php
$ip="{$_GET['ip']}";
$port="{$_GET['port']}";
if(!$sock=@fsockopen($ip,"$port", $num, $error, 5)) {
Header('Content-type: image/png');
echo"<img src='images/offline.png'>";
} else {
Header('Content-type: image/png');
echo"<img src='images/online.png'>";
}
?>

I've added the HTML too. As you can see it checks if the ports are open. It worked perfectly and I didn't have any issues with it at all.
Now, for a couple of days, I've been using an awardspace paid hosting, bought a domain name.
I use wordpress now, and I pasted this code directly in a PHP/HTML code box (I use a plugin that enables use of PHP) and it shows the HTML formatting how it should be, but unfortunately doesn't work as intended.
It shows everything to be down, while apache, mysql and my ftp server are still running on my computer (the IP it checks, 212.233.xxx.xxx).
When I set the IP to be 127.0.0.1, the IP of the awardspace server as far as my script is concerned, it shows only that the IP is working.

So, any suggestions? Any idea would be greatly appreciated 

Hi all!  I am trying to get an admin status ("y" or "n" to be retieved from an SQL select.  I do so in the following function:

Code: [Select]
function get_admin_status($username) {
   // query database for the name for a category id
   $conn = db_connect();
   
   $result = $conn->query("select admin from user
             where username='".$username."'");

   $result = @$conn->query($query);
   
   if (!$result) {
     return false;
   }
   $num_cats = @$result->num_rows;
   if ($num_cats == 0) {
      return false;
   }
   $row = $result->fetch_object();
   return $row->admin;
}

I then utilize this function in another file in the following code.  However, the adminhome.php page never loads.  It always goes to "survey1.php" .  I'm not sure why this is happening.  Any help would be appreciated.  Thanks for you time!

Code: [Select]
if ($username && $password) {
// they have just tried logging in
login($username, $password);
$admin = get_admin_status($username);
if($admin == "y"){
header("Location: adminhome.php");
}
else{
//login($username, $password);
// if they are in the database register the user id
$_SESSION['valid_user'] = $username;
$_SESSION['admin'] = $admin;
header("Location: survey1.php");
}

Hi all!

Also, does somebody have a link or something to a tutorial/pre-made script (although I'd like to follow instructions about it) about server statistics? I want to have data on how much a certain partition on the server has free or full. Thank you in advance.

 

i need to pull the records from where status not = rejected does anyone know the correct syntax?
Code: [Select]
$data=mysql_query("SELECT * FROM design WHERE id='$id' AND status!='rejected' ") or die (mysql_error());
