Zip en mappe med billeder

Jeg ved ikke hvordan, men lytter gerne med for at høre en løsning :o)

Hvis det er din egen server, så skulle der ikke være noget problem med at installere ena af disse. Hvis det ikke er din egen server så skal du snakke med dit webhotel.

Det er ikke på min egen server... Har selv googlet og fandt det samme :-)

Tænkte på om det kunne gøres uden et komponent.

Nej, det kan det desværre ikke.

Jeg ved at det kan lade sig gøre uden komponent med PHP.

PHP:

Det kræver jo du har en og anden funktion/komponent som kan lave en zip fil
Det er muligt der som standard er det i php
Men jeg har aldrig hørt om det i asp

Alternativt kan alt jo gøres gratis hvis man har viljen og styrken ;o)
Så kan man jo hvis man kender algoritmen selv kode funktionerne
Men jeg kender ikke algoritmen til zip og tror det er for omstændigt hehe ;o)

Ok. Vender tilbage når jeg har snakket med mit webhotel

xzip er kanont (Gratis), men kræver stadig at dit webhotel vil installere det.... Det er inst. der hvor jeg ligger.

don_g >> kommet videre? lukketid?

Hej.

Nu har jeg endelig snakket med mit webhotel. Der var ikke installeret noget komponent, men de ville kigge på det og svare tilbage hurtigst muligt.

Hvad svarede de så?

Lukketid?
