Upload souboru na server
cawte..., potřebuju nahrat soubor přímo z webu, aniž bych se připojoval přes FTP, našel jsem nějaké zdrojaky aj na webu..., ale ani muj ani z webu nefungoval.. nevite cim to je? mam na webzdarma.cz prava nahrat soubor pres php na svuj web..?
<HTML>Samozřejmě, že to lze. Ale bez bližšího popisu (jaký skript jsi zkoušel, jaké to vypisovalo chybové hlášky atd.) ti nikdo neporadí.</HTML>
Samozřejmě, že můžeš..
Proč "nefungoval"? ;) Nastavil jsi složce pro ukládání správné práva (aby tam mohl php server zapsat data)? Nepoužíval jsi zakázané funkce (jako copy(), ini_set())?

asi chybny kod, najdi si jiny, jestli umis googlovat.
Druha moznost, chybne nastaveni prav na souboru/adresari.

Peto, je sice pěkné, že už sis to jednou napsal, ale neuškodilo by ten tvůj kód taky trochu spravit - některé věci mi připadají opravdu poněkud zvláštní..
Např. nastavování práv adresáři pro zápis a potom zpátky - k čemu? Když už máš přístup ke složce tak, abys práva mohl změnit, tak můžeš většinou i zapsat soubor. Není potom jednoduší ty práva nastavit rovnou i pro zápis? ;)

Mimochodem anglický výraz pro UNIXové oprávnění je permission, nikoli law :)
