IF Statements? (phpBB3 Only)

[Comkid]

What are IF statements?
IF statements are used as HTML comments to make something happen if something has met the condition.

Why use IF statements?
Like in Twisty's guide at the start it uses an IF statement, which checks to see if the visitor is a guest and the register feature is not disabled.

How do you use IF statements?
To use IF statements, insert them like a HTML Comment, like this:

<!-- IF S_USER_LOGGED_IN -->Hello Mr. Logged In<!-- ELSEIF not S_USER_LOGGED_IN -->Please login kind sir<!--ENDIF -->

Structure of an IF statements?
First you will have the

IF statements loops?
To make a loop with IF statements you may use

<!-- ELSEIF condition -->

to end the an IF statement you must always use

Example Answer:

<!-- IF not S_USER_LOGGED_IN -->Please <!-- IF S_REGISTER_ENABLED -->Register or <!-- ENDIF -->Login<!-- ELSE IF S_USER_LOGGED_IN -->Welcome to my Site, Thank You for Signing Up<!-- ELSEIF U_ACP or U_MCP -->Welcome Staff<!-- ENDIF -->

But what is above is english, anyway, no I didn't know. There are coding languages like that for instance, Java:

int Comkid = 1

if (Comkid == 1){
Do something
}
