Language: PHP / Using Class Upload by Colin Verot
About: Multiple Uploading

The code below already uploads the files fine, it works…
PROBLEM: I am having trouble figuring out how to get the filename extension.
(In a comment below, I have specified where my problem area is…)

// CONNECTION TO DATABASE HERE...

// INCLUDE UPLOAD CLASS LIBRARY
include (dirname(__FILE__).'/lib/class.upload.php');

$files = array();
foreach ($_FILES['fileupload'] as $k => $l)
{
    foreach ($l as $i => $v)
    {
        if (!array_key_exists($i, $files))
        $files[$i] = array();
        $files[$i][$k] = $v;
        $imagename = $_FILES['fileupload']['name'];
    }
}

foreach ($files as $file) {

            // THIS IS MY PROBLEM AREA, GETTING FILE EXTENSION
            $ext=strchr($imagename,".");

            $generate_name = rand(100,99999); 
            $generate_name_extra = rand(200,9999);
            $filenamex = "PHOTO_".$generate_name.$generate_name_extra."_".time();
            $filenamex_thumb = $filenamex."_thumb";

            // COMPLETE FILENAME WITH EXTENSION
            $filename = $filenamex.strtolower($ext);
            $handle = new upload($file);
            if ($handle->uploaded) {
            ///// 1 ////////////////////////////////////////////////////////////////////
            $handle->file_new_name_body   = $filenamex_thumb;
            $handle->image_resize         = true;
            $handle->image_x              = '300';
            $handle->image_ratio_y        = true;
            $handle->jpeg_quality = '100';

            // ABSOLUTE PATH BELOW
            $handle->process($absoRoot.'covers/thumbs/');

            if ($handle->processed) {

            // SUCCESSFUL RESPONSE

        }
      else
        {

         // FAILED RESPONSE

        }     
    }
}

And the webform is:

<form method="post" action="upload.php" enctype="multipart/form-data">
<input name="fileupload[]" id="fileupload" type="file" multiple>

I really pretty much need the file extensions to serve the files correctly online, but I can’t spot where to find it. I have tried using: $files[$i][$k] instead of $imagename in my specified problem area above, as well as $file and other possible solutions, but I can’t spot which one’s going to give me the filename with extension.

Hopefully someone could point it out. Thank you for your time and assistance!

Answer 1

$ext=array_pop(explode('.', $imagename));
