Function not behaving...

[Wolf_22]

In my root directory, I have a folder named 'd'. Without going into semantics, it simply stands for "Downloads".

Having said that, I have a function which is included on my resume page of the following code:

function pdfGen1(){
    $active = basename($_SERVER['PHP_SELF']);
    $dir = './d/';
    if ($handle = opendir($dir)){
        echo '<ul>';
        while(false !== ($file = readdir($handle))){
            if(substr($file,-4) == '.pdf'){
                $displayName=ucfirst($file);
                echo'<li><span class='.$spanClass.'><a href="'.$file.'">'.$displayName.'</a></span></li>';
             }
             elseif(substr($file,-4) == '.doc'){
                $displayName=ucfirst($file);
                echo'<li><span class='.$spanClass.'><a href="'.$file.'">'.$displayName.'</a></span></li>';

             }
        }
        echo '</ul>';
        closedir($handle);
    }
} 

For the life of me, I cannot seem to grasp why I continually fail to make the function look in the folder 'd'. I'm thinking it's because of the way I have the $dir setup, but what other way is there?

If the directory is in root shouldn't it be -
$dir = '/d';

The variable

$spanClass 

is never used, nor is

$active

If the directory is in root shouldn't it be -
$dir = '/d';

Yep, ./ is "current directory";

The variable

$spanClass 

is never used, nor is

$active 

$active wont matter if its used or not as it's in the scope of the function but $spanClass will throw an error

[Wolf_22]

Okay, got rid of $active and $spanClass... Still no go. The error that's thrown is the following:

"Warning: opendir..."

This is what I have now:

function pdfGen1(){
    $dir = '/d';
    if ($handle = opendir($dir)){
        echo '<ul>';
        while(false !== ($file = readdir($handle))){
            if(substr($file,-4) == '.pdf'){
                $displayName=ucfirst($file);
                echo'<li><span><a href="'.$file.'">'.$displayName.'</a></span></li>';
             }
             elseif(substr($file,-4) == '.doc'){
                $displayName=ucfirst($file);
                echo'<li><span><a href="'.$file.'">'.$displayName.'</a></span></li>';
             }
        }
        echo '</ul>';
        closedir($handle);
    }
}

Are you sure that's the right server path for the directory?

On every server I've used it's more like this "/var/www/html/d/".

In all honesty - no. I've always had problems understanding subtle differences between addressing and relative locations on systems because of the way you have to think about them.

Resume.php is in my website's root or primary "master" folder, not my hosting space root folder (the folder on the server that would be something like "www" or "public_html"). Maybe I was stupid for not explaining that? I interpret "root" as being the first level of file / folder system which pertains to the actual hosted website at hand...

Get this - when I use "./d", it reads the files, but doesn't apply the correct linkage to the actual names of the files within the hyperlink. It's truly odd. The way I set that script up, it's supposed to read the files, output their names and link them to the files. How can it read the files but not apply the right linkage if the URL is off?

ahh ok.. so you need to look in document root not the system root directory.
Have you tried using glob() ? This function will print out a list of pdf, doc files in the directory where it is kept.

<?php

function fileList() {
    $files = glob("{*.pdf,*.doc}",GLOB_BRACE );
    if (!empty($files)) {
        $out = '<ul>';
        foreach ($files as $filename) {
            $out .= '<li><span><a href="'.$filename.'">'.ucfirst($filename).'</a></span></li>';
        }
        $out .= '</ul>';
        return $out;
    }
}
echo fileList();
?>

The GLOB_BRACE flag won't work on some systems though.

Close... I have to look in a folder within document root named 'd'. How would I modify the above to look in that folder?

[UFTimmy]

$_SERVER['DOCUMENT_ROOT'] . '/d/'; 

Note that the $_SERVER['DOCUMENT_ROOT'] is defined in Apache, so it could have the trailing slash or could have it left off. Adjust your code as needed (you'll need to remove the slash in front of /d/ if it does)
