Safer way to receive file uploads
function upload_file ($field, $target, $allow_overwrite = FALSE)
This is an easier & safer way to accept user files upload. Easier because it can accept multiple files upload easily, and safer because it denies unsafe file types (configurable in ACP > Configuration).
$field = file form field ID, can be array for multiple uploads.
$target = target folder OR folder with file name, can be array for multiple locations.
$allow_overwrite = if set true, will overwrite existing files. If set false, will rename the file if the same name exists.
This function will return an array of information, and uploaded file will be rename for safe file name.
The returned array:
Example 1. test.tpl
<h1>Welcome to test page!</h1>
<form name="myform" enctype="multipart/form-data" action="test.php"
method="POST">
<input type="hidden" name="cmd" value="upload" />
<input type="hidden" name="MAX_FILE_SIZE" value="30000" />
<p>Send these files:</p>
<ul>
<li><input name="userfile1" type="file" /></li>
<li><input name="userfile2" type="file" /></li>
<li><input name="userfile3" type="file" /></li>
</ul>
<p><input type="submit" value="Send File" /></p>
</form>
test.php
<?php
require './includes/user_init.php';
$cmd = post_param ('cmd');
switch ($cmd)
{
case 'upload':
$fields = array ('userfile1', 'userfile2', 'userfile3');
$status = upload_file ($fields, './public/file/', true);
print_r ($status);
break;
default:
$tpl = load_tpl ('test.tpl');
$txt['main_body'] = quick_tpl ($tpl, $txt);
flush_tpl ();
break;
}
?>
