Question

I got my php upload form working (allowing .jpg), but am not sure how to add .JPG (uppercase issue) or .jpeg.

Could someone please show me how to add these extensions to the following code?

<?php
//–°heck that we have a file
if((!empty($_FILES["uploaded_file"])) && ($_FILES['uploaded_file']['error'] == 0)) {
  //Check if the file is JPEG image and it's size is less than 350Kb
  $filename = basename($_FILES['uploaded_file']['name']);
  $ext = substr($filename, strrpos($filename, '.') + 1);
  if (($ext == "jpg") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") && 
    ($_FILES["uploaded_file"]["size"] < 16000000)) {
    //Determine the path to which we want to save this file
      $newname = dirname(__FILE__).'/upload/'.$filename;
      //Check if the file with the same name is already exists on the server
      if (!file_exists($newname)) {
        //Attempt to move the uploaded file to it's new place
        if ((move_uploaded_file($_FILES['uploaded_file']['tmp_name'],$newname))) {
           echo "It's done! The file has been saved!";
        } else {
           echo "Error: A problem occurred during file upload!";
        }
      } else {
         echo "Error: File ".$_FILES["uploaded_file"]["name"]." already exists";
      }
  } else {
     echo "Error: Only .jpg images under 15 Mb are accepted for upload";
  }
} else {
 echo "Error: No file uploaded";
}
?>

Thanks so much for your help and time!

You would probably change line 6 from:

if (($ext == "jpg") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") &&

to:

if (($ext == "jpg" || $ext == "jpeg" || $ext == "JPG") && ($_FILES["uploaded_file"]["type"] == "image/jpeg") &&

Although if you want to expand this further I’d recommend using an array of filetypes and checking the array, much easier to manage. Specifically using the in_array function http://php.net/manual/en/function.in-array.php
