vacsina hostingou maju mysql skus o nu poziadat
No viem, ze hosting s sql maju, ale ja mam zaplateny hosting bez sql. Inak sa to neda, iba cez sql? Nieje neaky skript, ktori ti zapise do iframe text, ktory si dal do imput type="text"? Nasiel som daco na internete, ale neviem to prisposobit na moju stranku. Funguje to len cez php (bez sql). Spravy sa vpisuju do .text suboru.
