Ciao a tutti, avrei un problema, in quanto quando un file viene uploadato sul mio sito ed ha lo stesso nome di un altro esso viene sovrascritto, così ho pensato di mettere un random code, faccio un esempio: il file che viene uploadato si chiama "ciao.txt" e con il codice random lo rinnomina in ghsl.txt
Il problema è che sò poco e niente di PHP e quindi, se possibile, vorrei una mano.
Codice PHP:
<script type="text/javascript" src="http://www.era404.com/js/swfobject.js"></script> <link href="_css/era404.css" rel="stylesheet" type="text/css" /> <script src="_js/swfobject.js" type="text/javascript"></script> <script type="text/javascript"> function formValidator() { var up = document.getElementById("flash_uploader"); var fb = document.getElementById('flash_block'); var upload_button = document.theForm.action_upload; var upload_url = "upload.php"; up.SetVariable("upload_to", upload_url); up.SetVariable("upload_dir", "<?php echo $dir ?>"); up.SetVariable("ul", "100"); upload_button.disabled='true'; return false; } function upload_complete(name,size,type,ft,dir,a) { window.location="index.php?name="+name+"&size="+size+"&type="+type+"&exts="+ft+"&dir="+dir+"&a="+a; } function fileProps(name,size,type,cdate,mdate,dir) { var props = document.getElementById('props'); props.innerHTML = "<div class='sucErr'><div class='tableHeader' style='width: 400px; height: 20px; padding-top: 5px;'>File selezionato:</div>
