Při zpracování BB značek došlo k samovolnému sežrání celého příspěvku. Pardon.
Zdravím

ako sa prenáša hodnota z javascriptu do php premennej,dole sa nachadza kód,ktorý som našiel na nete. Keď napr.stlačím tlačidlo uložiť,aby sa farba textu a pozadia preniesli do php skriptu.

Viem, že javascript pracuje na strane klienta a php na strane servera,ale podla mna musi byť nejaky spôsob,aby tieto dva jazyky spolu nejako spolupracovali.
Ďakujem za rady

Jistě, že způsob je, záleží jen který si vybereš, například:

1. Hodnotu můžeš přenést v URL ...page.php?color=...
2. Můžeš vyslat AJAX požadavek / new Image(); na PHP soubor, kde si předané hodnoty uložíš do sessions
3. Můžeš využít cookies

Zadna veta neobsahuje otaznik, takze se neptas, je to tak? :)

"podla mna musi byť nejaky spôsob,aby tieto dva jazyky spolu nejako spolupracovali"
Neni. Www prohlizec odesila data serveru a server www prohlizeci. Obvykle se tak deje odeslanim cele stranky.
Data muzes posilat napriklad pomoci skryty iframe, kde mas formular, ktery pres javascript odesles. Iframe se obnovi a spusti nejaky dalsi script.
Nebo pridas do stranky tag script (div.innerHTML, eval) <script src=soubor.php?posilam=ahoj&darek=zmrzlina></script>.
Rika se tomu ajax. Muzes pouzit knihovnu jquery.

Ten script, co tam mas, pouze vypisuje informace o prohlizecich. Neposila nic php.
