All Active Files Displayed

Will Refresh Every 5 Seconds ...

The problem that i am facing is that I do not know how to correctly input the variables $parts[0] and $parts[1] into a text box within the php loop.

Thanks in advance for any help.

I've not tried to understand what your code is doing, but, to insert a variable into an input:

<input type="text" name="..." value="<?php echo $parts[0]; ?>" />

CalebVenner · June 18, 2009

So I can run that WITHIN the PHP loop?

Edit: It reads and outputs the data within the filles

Order1.txt

Order2.txt

Order3.txt

Order4.txt

Order5.txt

Order6.txt

Order7.txt

Which vary in number.

If you put that within the loop you'd end up with x amount of inputs, each containing $parts[0] from that iteration of the loop - however they'd all have the same name which isn't obviously correct HTML. You could use instead:

<input type="text" name="someName[]" value="<?php echo $parts[0]; ?>" />

Explain what you're trying to do better...

Ok, thanks, I will see if it works and report back

Appreciate the help.

Accidental double post.

Ok, I have a folder full of text documents, what I would like to try and do is read the data from each file and output it into a textarea.

The problem is that the number of documents vary.

So I run the loop until it finds no more documents, then it ends and refreshes in 5 seconds.

Edit: I am trying to make it so that each file has its own text area

Adam · June 18, 2009

Why textarea if it refresh every 5 seconds, surely they wouldn't be able to edit it in time?

But basically similar concept, switch this line:

print $parts[0].$parts[1].'<br><br>';

To this:

print '<textarea name="someName[]">'.$parts[0].$parts[1].'</textarea><br><br>';

Thankyou for your help so far. ^.^

This is what I have so far, the page still remains blank for some reason, and I have a problem at the moment where I do not get any error reports.

Adam · June 18, 2009

Add this just after your first opening PHP tag:

ini_set('display_errors','1');
error_reporting(E_ALL);

CalebVenner · June 18, 2009

PROGRESS!

I am just playing around with it a bit to save you some hassel and learn a little bit ^.^

Will post back soon, thanks so much, really really appreciate it.

CalebVenner · June 18, 2009

Ok, SO I get the following error

Notice: Undefined offset: 1 in C:\PHP Root\Restaurant\DisplayOrders.php on line 20

With the code

<html>
<meta http-equiv="refresh" content="15" > 
<head>
<link rel="stylesheet" type="text/css" href="style/style.css"> 
<title>Order Display</title>
</head>
<body>
<?php
ini_set('display_errors','1');
error_reporting(E_ALL);
$FolderDate = date("d-m-y"); 
for ($FileNumber=1;$FileNumber<=1000;++$FileNumber) 
{
  if (file_exists("orders/$FolderDate/Order$FileNumber.txt")) 
{							
$data=file("orders/$FolderDate/Order$FileNumber.txt"); 
foreach ($data as $d) 			
	{
      		$parts=explode('=',$d); 		   
      		print '<textarea name="someName[]" style="width: 256;height: 128;">'.$parts[0].$parts[1].'</textarea><br><br>'; 

	}   					
} 
else 
{		
        exit("All Active Files Displayed<br>Will Refresh Every 15 Seconds ... ");
}
}
?>
</body>
</html>

Line 20 Being

print '<textarea name="someName[]" style="width: 256;height: 128;">'.$parts[0].$parts[1].'</textarea><br><br>';

Also I was wondering how I insert a break after each line into the following code snippet, I had it before, have just forgotten

			

                        fputs($file, "Extra Notes: $notes");
		fputs($file, "Server: $servingstaff");
		fputs($file, "Date: $time");

Thanks you to anyone that helps.

EDIT: Will just use "/n" for the break

Adam · June 18, 2009

It's a notice telling you that $parts[1] isn't actually set (the key '1' doesn't exist). Just quickly add some debugging code to find out what's in the $data array, like so:

print '<pre>';print_r($data);print '</pre>';

Add that just after $data = ......

Also (I know I'm annoying ^.^), Becuase It is output to the text file with a break between each set of info. when they are input to the page they all get displayed in a spereate text box per line, if I leave out the breaks it's not very legable as the entire text file is displayed in the same box with one space between each set of information., any ideas?)
