Questo codice carica un file nella cartella uploads e gli assegna il numero 1. Adesso ho un problema. Se la cartella in cui viene caricato il file (uploads), contiene già il file chiamato 1, dovrebbe rinominarlo assegnando al file il numero immediatamente più grande di quello già esistente. (Es. se è presente 1 --> rinomina ->2 ; se è presente 2 rinomina 3 ecc)

Come posso fare? Sto impazzendo letteralmente...
Ho bisogno che i file caricati abbiano un numero crescente a partire da 1.. poi 2...poi 3...

a parte che hai postato un po' troppo codice :) ...

potersti fare così: crea un file "counter.txt" (anche nella stessa cartella degli altri file) con permessi di lettura/scrittura che contiene il solo carattere "0" (zero), poi quando assegni il nome anzichè:

Codice PHP:


If($random_name){

$file_name[$i]=1;

} Else {

$file_name[$i]=cln_file_name($_FILES['file']['name'][$i]);

}

fai:

Codice PHP:


$counterfile = '........./counter.txt'; // vedi un po' se indicare una cartella...

If($random_name){

$counter = file_get_contents($counterfile);

file_put_contents($counterfile, ++$counter);

$file_name[$i]=$counter;

} Else {

$file_name[$i]=cln_file_name($_FILES['file']['name'][$i]);

}

scusate ma non potrebbe usare la funzione rename()?

il "problema" è tener "traccia" del contatore per sapere il "prossimo" file come dev'essere denominato... naturalmente ci sono tante soluzioni...
