Unable to open PDF documents from PHP Page

Hello all,

I am having problems setting up a php page that lists PDF documents. Using the code below, I am able to list pdf's in a giver folder, but when I click on the pdf file from the page, it tells me "Page cannot be found"...

I am able to open pdf links from other web site, just not from the php page. I've also tried multiple pc's, none worked...Any thoughts or ideas?


<?php // RAY_EE_RSS_news_index.php
error_reporting(E_ALL);
date_default_timezone_set('America/Chicago');

// THE PATH TO OUR CURRENT WORKING DIRECTORY
$dir = getcwd();

// APPEND A SLASH IF NEEDED
if ($dir[strlen($dir)-1] != DIRECTORY_SEPARATOR) $dir .= DIRECTORY_SEPARATOR;

// AGGREGATE THE DIRECTORY INFORMATION INTO AN ARRAY OF ARRAYS
if ($dh = opendir($dir))
{
    $dir_datas = array();
    while ($file_name = readdir($dh))
    {
        // WE ONLY WANT TO CONSIDER FILES NAMED LIKE *.PDF
        $ext = end(explode('.', $file_name));
        $ext = strtoupper($ext);
        if ($ext == 'PDF')
        {
            $my_name = $dir . $file_name;
            $my_data = array
            ( 'name' => $file_name
            , 'size' => filesize($my_name)
            , 'time' => date('c', filemtime($my_name))
            )
            ;
            $dir_datas[] = $my_data;
        }
    }
}

// IF NO PDFS
if (empty($dir_datas)) die();

// CALL THE FUNCTION TO SORT THE ARRAY BY THE filemtime()
usort($dir_datas, 'timesort');

// GET THE URL PATH
$poz = strrpos($_SERVER["PHP_SELF"], DIRECTORY_SEPARATOR);
$urp = substr($_SERVER["PHP_SELF"], 0, $poz) . DIRECTORY_SEPARATOR;

// CREATE LINKS TO EACH OF THE FILES
$out = NULL;
foreach ($dir_datas as $pdf)
{
    $out .= $pdf["time"];
    $out .= ' ';
    $out .= '<a target="pdf" href="'
    . $urp
    . $pdf["name"]
    . '">'
    . $pdf["name"]
    . '</a>'
    . ' '
    . showfilesize($pdf["size"])
    . '<br/>'
    . PHP_EOL
    ;
}

// CREATE AND DISPLAY THE VIEW OF THE DIRECTORY
$htm
= '<h1>'
. "CIENA SERVICE OF PROCESS DOCUMENTS: "
. date('F j, Y')
. '</h1>'
. $out
;
echo $htm;
die();




// A USER SORT FUNCTION TO ORDER BY DATETIME DESC
function timesort($a, $b, $key='time')
{
    if ($a[$key] == $b[$key]) return 0;
    return ($a[$key] > $b[$key]) ? -1 : 1;
}

// FUNCTION TO PRODUCE AN EASY-TO-READ DESCRIPTION OF THE SIZE OF A FILE
function showFileSize ($xb)
{
    $pb = 1024*1024*1024*1024*1024;
    $tb = 1024*1024*1024*1024;
    $gb = 1024*1024*1024;
    $mb = 1024*1024;
    $kb = 1024;
    if     ($xb >= $pb) { $text = number_format(($xb / $pb),3) . " PB"; }
    elseif ($xb >= $tb) { $text = number_format(($xb / $tb),2) . " TB"; }
    elseif ($xb >= $gb) { $text = number_format(($xb / $gb),1) . " GB"; }
    elseif ($xb >= $mb) { $text = number_format(($xb / $mb),1) . " MB"; }
    elseif ($xb >= $kb) { $text = number_format(($xb / $kb),0) . " KB"; }
    elseif ($xb >= 0)   { $text = number_format( $xb       ,0) . " bytes"; }
    else                { $text = "0 bytes"; }
    return $text;

Hi,
Are the url's on the page the same as the one's you are calling it from other
links?

No. As it turns out, the page I'm viewing the list of pdf's is http://servername/folder/ciena.php, but the error page shows that it is pointing to a target of http://servername/pdfname.pdf so I think therein lies the problem but I don't know how to fix it.

I'd like the target of the pdf to be the same folder that the php page is located.

if you are only calling files from the current working directory, you don't need to add the path to it?

I would think so, but it doesn't seem to be working like that...

if you comment  out line 51 it will not add the directory path, obviously if you want it to look at other directories this wont work.

Commenting out line 51 worked. Now the target is the same as the location of the files. Thanks.
