Dispay text files

Post subject:  Dispay text files
Ok, here is what I want to do.

I have a directory with a bunch of *.txt files in it. What I want is to generate a list of all the file names, and places them on a page. The list will be links, so that when you click on one of them, the *.txt file will be displayed.

Now the part I am having trouble with. What I want is for the *.txt file to be displayed on the same page as the the list of files, but underneath. (ie, like this http://www.redclaw.ca/funnypics.php ).

I got it working for the pics page, but I can't get it working for the 'text jokes'.

Here is the code I am using for the pics page:
code:
<?php



$directory_name = "funPics";
$dh = dir($directory_name);
$i = 0;

$entry = $dh->read();
$entry = $dh->read();

while ($entry = $dh->read()) {


        if ($i==0){

                echo "<tr>";

        }

        echo "<td>";
        echo "<a href = \"http://www.redclaw.ca/funnypics.php?var=$entry\">$entry</a>";


        echo "</td>";
        echo "\n\n";

        $i++;


       
        if ($i == 3){
                $i=0;
                echo "</tr>";
        }

}

if ($i != 0){

        echo "</tr>";

}




?>

<!-- HTML formatting -->

<?php

if ($var != null){


        echo "<img src=\"/funPics/$var\" border=\"0\" alt=\"$var\" />";


}


?>


The problem I'm having modifying this code is that I think I will have to read in the *.txt line by line and then output it, and I just can't get it to work. I've spent much time on the PHP website working on this. Any help would be great.

Thanks.

What about using include() to insert the text of the document?

code:
<pre><?php include($_GET["var"]); ?></pre>

Ok, I tried that here:
http://www.redclaw.ca/textjokes.php

Try clicking on one of the options and see so that you can see the error.

code:

<?php

if ($var != null){

        include($_GET[ "/funPics/$var" ]);
?>

code:
<?php

if ($var != null){

   include("/funPics/".$_GET['$var']);
?>

That generate this error:
Warning: main(): Unable to access /jokes/ in /home/virtual/site118/fst/var/www/html/textjokes.php on line 134

Warning: main(/jokes/): failed to open stream: No such file or directory in /home/virtual/site118/fst/var/www/html/textjokes.php on line 134

Warning: main(): Failed opening '/jokes/' for inclusion (include_path='.:/php/includes:/usr/share/php:/usr/share/pear') in /home/virtual/site118/fst/var/www/html/textjokes.php on line 134


Oh, and I changed the dir 'funPics' to 'jokes' which is what it should be.

okay. there are two ways i'd do this: include the file, or use an iframe.
including i dont like because when you include the text file, it usually doesnt show the new lines where they're supposed to be. using an iframe does that, and it lets you scroll down. i made 2 test pages and you can check them out here.

include:
http://uifgames.8-bit.ca/scripts/txtindex.php
code:

<?

  if ($handle = opendir('txt')) {

    while (false !== ($file = readdir($handle))) {
      if(($file != ".") && ($file != "..")){ 
        echo "<a href=\"txtindex.php?pg=$file\">$file</a><br>";
      }
    }


    closedir($handle);
  }

  if(isset($_GET['pg'])){
    include("txt/" . $_GET['pg']);
  }

?>



iframe:
http://uifgames.8-bit.ca/scripts/txtindex.php
code:
<head>
  <script language="JavaScript">
  <!--
    function changeframe(file){
      document.getElementById('textframe').src = file;
    }
   -->
  </script>
</head>
<?

  if ($handle = opendir('txt')) {

    while (false !== ($file = readdir($handle))) {
      if(($file != ".") && ($file != "..")){ 
        echo "<a onClick=\"changeframe('txt/$file')\" href=\"#\">$file</a><br>";
      }
    }


    closedir($handle);
  }

  echo "<iframe id=\"textframe\" name=\"textframe\"></iframe>";

?>


go into http://uifgames.8-bit.ca/scripts to see the files and directory

as for your including problem.. the directory you are pointing to doesnt exist... so yer obviously gonna have to fix your paths

http://www.redclaw.ca/textjokes.php?pg=City_Boy.txt
