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
.
