Free PHP Scripts / making file upload optional rather than required field
« on: February 13, 2012, 09:06:39 PM »
Hey Guys,
First of all I have to say I am quiet new on PHP and still trying to understand the structure

I did create a contact form and  added a section to upload files (from a free code over internet) for the clients'. however the form is assuming that every client has to upload a file in order to submit the form.

My question is is there any way to convert this into an optional field.  to be honest I tried to add  'allowEmpty' => true  but it did not work.

Do you guys have any suggestions for that.
any help would be greatly appreciated.



// Configuration - Your Options
      $allowed_filetypes = array('.jpg','.pdf','.dwg','.jpeg'); // These will be the types of file that will pass the validation.
      $max_filesize = 10485760; // Maximum filesize in BYTES (currently 0.5MB).
      $upload_path = './asparagas/'; // The place the files will be uploaded to (currently a 'files' directory).
 
   $filename = $_FILES['userfile']['name']; // Get the name of the file (including file extension).
   $ext = substr($filename, strpos($filename,'.'), strlen($filename)-1); // Get the extension from the filename.

  // Check if the filetype is allowed, if not DIE and inform the user.
   if(!in_array($ext,$allowed_filetypes))
      die('The file you attempted to upload is not allowed.');
   // Check if the filetype is allowed, if not DIE and inform the user.
   if(!in_array($ext,$allowed_filetypes))
      die('The file you attempted to upload is not allowed.');
 
   // Now check the filesize, if it is too large then DIE and inform the user.
   if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize)
      die('The file you attempted to upload is too large.');
 
   // Check if we can upload to the specified path, if not DIE and inform the user.
   if(!is_writable($upload_path))
      die('You cannot upload to the specified directory, please CHMOD it to 777.');
 
   // Upload the file to your specified path.
   if(move_uploaded_file($_FILES['userfile']['tmp_name'],$upload_path . $filename))
   echo ''; // It worked.
 }
      else
         echo 'There was an error during the file upload.  Please try again.'; // It failed :(.


Regards,

Ahmet
