File Upload


Contents



Τα παρακάτω προγράμματα υλοποιούν την διαδικασία του file upload με δύο τρόπους.
Ο πρώτος είναι σαφέστατα ο πιο απλός, ο δεύτερος πιο "επαγγελματικός" καθώς
γίνεται η αποθήκευση ενός αρχείου από το μηχάνημα μας στον διακομιστή μέσω ftp.

Web File Upload 


<?php
if ( empty($_FILES['uploadedfile']['name']) ) {
?>

<form enctype="multipart/form-data" action="" method="POST">
Choose a file to upload : <input name="uploadedfile" type="file" />
<input type="submit" value="Upload File" />
</form>

<?php
} else {

$target_path = "uploads/";

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ".  basename( $_FILES['uploadedfile']['name'])." has been uploaded";
} else
    echo "There was an error uploading the file, please try again!";

}
?>
