Siema, mam problem, o funkcji $_GET czytalem duzo, a nie wiem jak zrobić więc tutaj napisałem.Mam wyszukiwarke, chce jeżeli klikne w "szukaj" otworzylo mi się to w danym divie a nie na nowej stronie bez tresci strony. Przykladem takiej wyszukiwarki moze byc nawet http://www.dobreprogramy.pl/ wpisuje tekst, klikam szukaj i w danym divie otwiera mi sie zawartosc wyszukiwania, a nie poprostu sam tekst wyszukania. Wiem, ze rozwiazaniem moze byc poprostu dania w index.php kodu

[PHP] pobierz, plaintext 
				if($_GET['id']=="szukaj"){
		include("search.php");
	}
[PHP] pobierz, plaintext 

a na stronie glownej umiescic tylko hiperlacze do search.php

[HTML] pobierz, plaintext 
<a href="index.php?id=szukaj">wyszukiwarka</a>
[HTML] pobierz, plaintext 

Ale chce się nauczyc czego innego, szukam innych rozwiazan, ale jeszcze poczatkowych (nie wszystko odrazu )

Z góry dzięki

Funkcja $_GET?

Pomysł z tym kodem co tam podałeś na początku jest "dla prostych stron" wystarczający... nie wiem dlaczego musiałbyś robić jakiś odnośnik... niech po prostu formularz kieruje na ...?id=szukaj.

tak, chce aby kierowal do ?id=szukaj, ale odrazu z wyszukana fraza :/

zapomnialem dodac, ze mam wyszukiwarke JSSEARCH, podam teraz tresc searchENGINE.js
