PHP upload_class
Easy to use upload functions for (multiple) file upload with validation.
Example (of use):
php:
<?php
include ($DOCUMENT_ROOT."/classes/upload/upload_class.php"); //classes is the map where the class file is stored (one above the root)
$max_size = 1024*100; // the max. size for uploading
$my_upload = new file_upload;
$my_upload->upload_dir = $DOCUMENT_ROOT."/files/"; // "files" is the folder for the uploaded files (you have to create this folder)
$my_upload->extensions = array(".png", ".zip"); // specify the allowed extensions here
// $my_upload->extensions = "de"; // use this to switch the messages into an other language (translate first!!!)
$my_upload->max_length_filename = 50; // change this value to fit your field length in your database (standard 100)
if(isset($Submit)) {
$my_upload->the_temp_file = $_FILES['upload']['tmp_name'];
$my_upload->the_file = $_FILES['upload']['name'];
$my_upload->http_error = $_FILES['upload']['error'];
$my_upload->replace = (isset($_POST['replace'])) ? $_POST['replace'] : "n"; // because only a checked checkboxes is true
$my_upload->do_filename_check = (isset($_POST['check'])) ? $_POST['check'] : "n"; // use this boolean to check for a valid filename
$my_upload->upload();
// use the following if clause to do something if the upload is true
/* if ($my_upload->upload()) {
do something ... like insert the filename to the database
} */
}
?>
