Could have been nice to have masterskill study guide , softcopy eg. PDF version as well .. I find it easy reading from my notebook .. just started with 3A , from 2 was spending much time on prescribed book BEGINNING PHP5, APACHE and MYSQL web development handbook book ( I read the book and do the practicals before going to a topic and after the topic ) ... also spending a whole lot of time on PHPBUILDER.COM its a nice forum with examples and a big community

Just done with Task 3. Had a problem with getting my variables from one forum to another. But figured that out. For example: The Guestbook one. In the form guestbookform.php you have the Firstname and lastname input plus the Comments. And in guestbook.php where it has to write the firstname, lastname and comments to the text document, I kept getting the parse error variables $firstname, $lastname and $comments does not exist. Reading through a few forums came across codding that helped a lot. Just under <?php I put this code in:

$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$comments = $_POST['comments'];

Problem solved. So my opinion is if you struggling with something forums is very helpful!!!!

I'm done, but it took me a while to work around, visiting old forums does help.

Now that was really cool smile
No hassles with the hit counter and the guestbook ... and it was easier than I thought it would be. Am really chuffed that it works and looks good !!
Still having an issue with putting my semi-colons and quotes in the right places but getting there. Hopefully 3B-2 is as smooth.

I'm really struggling with Task 3B-2.

Searched old forums but can't find the solution.

Everything else works but can't access the Test and Network folders.

Please help.

Here's the code: 
Language: PHP
<?php
/*This script creates a directory navigation script that allows users to view the contents of a directory
as well as the contents of the files within the directory.*/
$dir = NULL;
if(!$dir)
 $dir = ("./");
$dp = opendir($dir);
echo "<table border=';0'; width =';100%'; cellspacing=';0'; cellpadding=';0';>\n";
while($filenames[] = readdir($dp));
sort($filenames);
for($i = 0; $i < count($filenames); $i++) {
 $item = $filenames[$i];
 
 if(is_dir($item)) {
  if($item != ';.'; && $item != ';..';)
   echo "<tr><td width=';100%';><a href=';".$_SERVER[';PHP_SELF';]."?dir=".$dir.$item."';>".$item."/</a></td></tr>\n";
  }
  else
   echo "<tr><td width=';100%';><a href=';$dir/$item';>$item</a></td></tr>\n";
}
 
echo "</table>";
?>

Hi guys,

I'm still struggling with task 3B-2. Truan Frames gave me advice as to add $dir=$GET_['dir'] at the top of the code. This works but I get an error message in the browser: Notice: Undefined index: dir in ....

Here's my code: 

Language: PHP
<?php
/*This script creates a directory navigation script that allows users to view the contents of a directory
as well as the contents of the files within the directory.*/
$dir = NULL;
$dir = $_GET[';dir';];
if(!$dir)
 $dir = ("./");
$dp = opendir($dir);
echo "<table border=';0'; width =';100%'; cellspacing=';0'; cellpadding=';0';>\n";
while($filenames[] = readdir($dp));
sort($filenames);
for($i = 0; $i < count($filenames); $i++) {
 $item = $filenames[$i];
 
 if(is_dir($item)) {
  if($item != ';.'; && $item != ';..';)
   echo "<tr><td width=';100%';><a href=';".$_SERVER[';PHP_SELF';]."?dir=".$dir.$item."';>".$item."/</a></td></tr>\n";
  }
  else
   echo "<tr><td width=';100%';><a href=';$dir/$item';>$item</a></td></tr>\n";
}
 
echo "</table>";
?>


I think I add this because I want the same script to run again based on another folder.

Please let me know where to add this piece of code ($dir=$GET_['dir']) so that I don't get this error message.

Language: PHP
$dir = NULL;

Do you understand why? It's in the handbook... smiling smiley And, asxmgcoyi rightly asks, what ARE you trying to achieve with that? The code is not necessarily correct, but let us assume for a moment it is. Hence you are destroying the variable you want to use in the next line????

I added $dir = NULL because I was getting an error saying that $dir is an undefined variable.

I added $dir = $_GET['dir'] at the top and it works, except I'm getting an error - Notice: Undefined index: dir in C:\wamp\www\StudentPHP\directory_navigator.php on line 5.

I'm no longer getting the "undefined variable" error anymore. The "Undefined index: dir" is the only error now.

I think I understand why we add $dir = $_GET['dir']:

//We want to see if $dir exists or not because we cannot say "if it doesn't exist" without checking if it exists or not.

About the error...it could be because I'm running the latest Wamp and not Xaamp? confused smiley

Also, it seems that xmgcoyi also struggled with this task. I would like to know how other guys did it with such ease. Did u just look in the old forums and just add and that was it? Or did u try to understand? Just a question. confused smiley

Here's my code: 

Language: PHP
<?php
/*This script creates a directory navigation script that allows users
  to view the contents of a directory as well as the contents of the files
  within the directory.*/
 
//We want to see if it exists or not because we cannot say "if it doesn';t exist" without checking if it exists or not.
$dir = $_GET[';dir';]; 
if (!$dir)
$dir = ("./");
$dp  = opendir($dir);
echo "<table border=';0'; width=';100%'; cellspacing=';0'; cellpadding=';0';>\n";
while($filenames[] = readdir($dp));
sort($filenames);
for ($i = 0; $i < count($filenames); $i++){
 $item = $filenames[$i];
 if (is_dir($item))
 {
  if($item != ';.'; && $item != ';..';) 
  echo "<tr><td width =';100%';><a href=';".$_SERVER[';PHP_SELF';]."?dir=".$dir.$item."';>".$item."/</a></td></tr>\n";
 }
 else
 {echo "<tr><td width=';100%';><a href=';".$dir."/".$item."';>{$item}</a></td></tr>\n";
 }
}
echo "</table>";
?>

That means you place it all in a conditional statement 

Language: PHP
if(isset($_GET[';dir';]))
{
$dir = ("./");
$dp  = opendir($dir);
.........
}
 
//or
 
 
if(!isset( $_GET[dir])) { $_GET[dir]=""; }
 
//or
 
echo (isset($_GET[';dir';])) ? $_GET[';dir';] : ""; 
 
// which is another way of say if/else - the part after the ? is the 1st bracket code and the part after the : is the else part.

A browser just displays the results of the parsed code, which is handled by Apache, so it has no influence. More likely different server and php configurations - usually error-reporting settings (why it is not standard I won't know). Having said that, the suggestions i made here above is a good standard to follow wether your receive the error message or not.
