if,then,else statements in html----HURRY!!!!

I need to know if there are any sort of staements like if and then in html. In pascal it would be like this:

Code:

begin
if VariableHere = TheValue then
...other code here

So it will check if a variable has a certain value. Basicly what i want it for is a Password and Username page. So if you enter the correct password then it will go to the next page. If you give me code please put comments in your post because im new at this. Also i'm going to make a serach area that will search for something. Basicly if you enter a value it will go to the corsponding page. But only if the value is registered in an array of some sort. I'm just spit balling but help is ++++++++needed. Thanks bunchs.

Can't do this in strictly html.

You need to combine this with a scripting language like javascript or php.

 

http://php.net
http://w3schools.com

Javascript is client-side so you will not want to use that for a logins.

 

That's true, also use another language to make a website or so, PHP or so should be better

 

VBScript is what you're looking for, Google has your answer
