Getting file sizes for files in another directory

I have a simple php page setup to display the files in a given directory. For the root folder it works fine. But as soon as I change directories I get:

Warning: filesize(): stat failed for blahblahblah on line blah

 

and of course. not file sizes.

 

Here is the bit of code I think is causing the issue:

Line 29:

// Adds pretty filesizes
function pretty_filesize($file) {
    $size = filesize($file);
    if ($size < 1024) {
        $size = $size . " Bytes";
    } elseif (($size < 1048576) && ($size > 1023)) {
        $size = round($size / 1024, 1) . " KB";
    } elseif (($size < 1073741824) && ($size > 1048575)) {
        $size = round($size / 1048576, 1) . " MB";
    } else {
        $size = round($size / 1073741824, 1) . " GB";
    }
    return $size;
}

and line 184:

            $sizekey=filesize($dirArray[$index]);

And the referenced $dirArray[index]:

// Loops through the array of files
for ($index = 0; $index < $indexCount; $index++) {
 
    // Decides if hidden files should be displayed, based on query above.
    if (substr($dirArray[$index], 0, 1) != $hide || ($currdir != "." && $dirArray[$index] == "..")) {
 
        // Resets Variables
        $favicon = "";
        $class = "file";
 
        // Gets File Names
        $name = $dirArray[$index];
        $namehref = ($currdir == "." ? "" : $currdir . '/') . $dirArray[$index];
 
        // Gets Date Modified
        $modtime = date("M j Y g:i A", filemtime($dirArray[$index]));
        $timekey = date("YmdHis", filemtime($dirArray[$index]));

Not sure what is throwing the error...

 

Thanks in advance

...

 

Not sure what is throwing the error...

blahblahblah is throwing the error on line blah. Have a look at that file and that line (and a couple of lines before). You could debug this by printing the $file value when $size becomes false (i.e. the call failed).

 

Most likely, the problem is the path. filesize requires the full path of the file to be checked. If a relative path (or just a filename) is provided, it will look in the current working directory.

 

It might also be a permission issue, but since only you saw the error message, we can't really say.

 

Note: When posting error messages on this site, post the entire message. You can X-out any sensitive information if you want. In my experience, PHP has very few (if any) cryptic error messages, if you read the message it tells you what, when, where and why.

It would be the path they navigate to.

 

The code you showed does not provide enough information about where the filenames came from or even what is in the array. If you are using glob or readdir, you will need to prepend the same path you gave those functions to the filename you are checking.

 

Is your $namehref variable getting the correct value? If so, maybe you want to use the same thing you did there.

 

Also, your calls to filemtime should be having the same problem as the call to filesize.

Well here is the whole code.

See here is what we have going on (follow me on this one)

 

1) We have cloud storage. We also have could computing. 2 different services, same provider.

2) Cloud storage is utilized through Atmos GeoDrive (AT&T). So we had to install the access app on all of our clients, including the Cloud Server, to manage a file structure and files. (Drive Z:) on the cloud server

3) We also set up XAMPP on the cloud server to host a small site, to display the files on the cloud storage (Drive Z: through Atmos GeoDrive)

 

I can see the file structure when I go to the site running the above code. But when I click on any directories, I see the files, but no file sizes and I cannot retrieve or view any of the files, because it is point the files to file:///z: etc.

 

If I change the directory in the code to just "." instead of "z:" (Line 46,47) then I get the directory of the webroot, and I can click on files and retrieve them or view them.

 

I am soooo confused right now, it's not even funny.
