Help with displaying text files

Hi guys,

So today I am trying to do something that is probably quite simple. But my head is all over the place and I can barely think straight! Something which is not good for a newb!

I'm trying to display some text files on the web. These text files are all in their own seperate directory. I want to be able to list the directory. When you the file you want to view you are brought to a page which uses this code to display the text:

PHP Syntax (Toggle Plain Text) 
  1. <?php 
  2. $myFile = "directory/file.txt";
  3. $fh = fopen($myFile, 'r');
  4. $theData = fread($fh, filesize($myFile));
  5. fclose($fh);
  6. echo "<pre>$theData</pre>";
  7. ?>

The code I have to display the directory is:

PHP Syntax (Toggle Plain Text) 
  1. <?php
  2. $dir = "poems/"; 
  3. if($scan = scandir($dir)){ 
  4. 	foreach ($scan as $value){ 
  5. 		if($value != "." && $value != ".."){
  6. 			echo $value."<br />";
  7. 		}
  8. 	}
  9. }
  10. ?>

So in summary what I want is:
1. Using the second piece of code or similar display a list of contents.
2. Once you choose a link the page it displays using the first piece of code or similar.

I presume I should be using some kind of template solution to make my site run the way i want.

I'm sorry if I explained it all over the place but as I said im kind of all over the place at the moment! Thanks guys

Try this code. I have written but not tested it, hopefully it will work for you.

php Syntax (Toggle Plain Text) 
  1. <?php
  2.  
  3.  
  4. $dir="poems/";
  5. printContents($dir);
  6.  
  7. if(isset($_REQUEST['f']))
  8. {
  9. 	$fh = fopen($_REQUEST['g'],"r");
  10. 	$theData = fread($fh,filesize($_REQUEST['f']));
  11. 	fclose($fh);
  12. 	echo "<pre>$theData</pre>";
  13. }
  14.  
  15. function printContents($directory)
  16. {
  17.                 if($scan = scandir($directory))
  18. 	{
  19. 		foreach ($scan as $value)
  20. 		{
  21. 			if (is_dir($value) && $value!="." && $value!="..") {
  22. 				printContents($directory);
  23. 			}
  24. 			else if(is_file($value))
  25. 			{
  26. 				echo "<br/>Read contents for ";
  27.                           echo "<a href=\"content_page.php?f=".$directory."/".$value."\">";
  28.                           echo $directory."/".$value."</a>";
  29. 			}
  30. 		}
  31. 	}
  32. }
  33. ?>

Dasatti thanks once again for you help. The code for outputting the directory list is working perfectly.

However there are 2 small problems. One it's outputting the dots at the top:

.
..

And the second when I click the link I get the following:

The requested URL /Site/content_page.php was not found on this server.

Thanks!

Hi there,

Here's the modified version of Dasatti's printContents:

PHP Syntax (Toggle Plain Text) 
  1. <?php
  2.  
  3. $dir = "poems/";
  4. printContents($dir);
  5.  
  6. if(isset($_REQUEST['f'])){
  7. 	$fh = fopen($_REQUEST['f'],"r");
  8. 	$theData = fread($fh,filesize($_REQUEST['f']));
  9. 	fclose($fh);
  10. 	echo "<pre>$theData</pre>";
  11. }
  12.  
  13. function printContents($dir) {
  14.     $mydir = opendir($dir);
  15.     while(false !== ($file = readdir($mydir))) {
  16. 	if($file != "." && $file != "..") {
  17. 	    if(is_dir($dir.$file)) {
  18. 	        printContents($dir.$file) ; 
  19. 	    }
  20. 	    else{
  21. 	        echo "<br/>Read contents for ";
  22.                 echo "<a href=\"list.php?f=".$dir."/".$file."\">";
  23.                 echo $dir.$file."</a>";
  24. 	    }
  25. 	}
  26.     }
  27.     closedir($mydir);
  28. }
  29.  
  30. ?>

You probably forgot to change the target page content_page.php to the one which you are testing your code in. In my case, i was using a file code list.php, hence in the anchor tag i used list.php.

Either rename the page to content_page.php or change the href attribute in line no 28 to the name of the file to which you saved it with.

php Syntax (Toggle Plain Text) 
  1.  echo "<a href=\"<place_the_name_of_the_php_file_here>?f=".$directory."/".$value."\">";
