File upload script conditions ?
Posted: Tue Dec 27, 2011 1:58 pm
Hello ,
I have this script for uploading files .
It takes the name of the file from the previous page .
when the file type is not allowed or there's no file , the message that will appear is
"The file you attempted to upload is not allowed"
so i want to make a condition with if statement to skip the file checking part if there's no file to upload.
I mean , if the filename="" , i want to skip all the if statements below.
I did it but it's not seem to work ! i dunno why
<?php
// Configuration - Your Options
$allowed_filetypes = array('.jpg','.gif','.bmp','.png','.docx… // These will be the types of file that will pass the validation.
$max_filesize = 2000524288; // Maximum filesize in BYTES (currently 0.5MB).
$upload_path = './uploads/'; // 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).
$filename = time() .'_'. $filename;
$ext = substr($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.');
// Now check the filesize, if it is too large then DIE and inform the user.
if(filesize($_FILES['userfile']['tmp_nam… > $max_filesize)
die('The file you attempted to upload is too large.');
// Check if we can upload to the specified path, if not DIE and inform the user.
if(!is_writable($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'… . $filename))
echo '<center>Your file upload was successful</center>'; // It worked.
else
echo 'There was an error during the file upload. Please try again.'; // It failed
