[SOLVED] If Statement

[JoeCullen]

Hi guys,

 

I guess this is a really easy thing to solve but im new to coding and being quite dumb..

 

I want to put and If statement with 2 variables, without using ElseIf.

 

Here is what i mean:

 

if ($_REQUEST["firstname"]=="") AND ($_REQUEST["lastname"]=="") {
  echo "Write Your Name!";
} else {
  echo "Hello";
}

 

I cant figure out the AND bit. I realise the whole IF has to be in brackets but cant find the syntax for the AND in the middle

 

Please help!

 

Joe

1) This has absolutely nothing to do with math. Topic was moved.

 

2) Don't use $_REQUEST; use $_GET or $_POST instead, depending on what you're actually looking for.

 

3) Try this (note the parens surrounding the WHOLE if statement):

if (($_POST['firstname'] == "") && ($_POST['lastname'] == "")) {
...............

 

4) && is nicer than AND, imo. xD

It's not just a matter of niceness, AND/&& and OR/|| have different operator precedent values.

 

"blah or die (xxx)" is not the equivalent of "blah || die(xxx)"

It's the same for that case, I believe, but it can affect things sometimes.

You've just got to have the last say don't you?

What?  I was saying that it didn't really matter in that particular instance.  I mean, the operator precedence CAN affect things, but not here.  Chill out.

Lol, DarkWater you are proving Thorpe right.

 

Btw OP if the topic is solved there is a link at the bottom left.

Thanks for the help "&&" works great

The precedences are never the same.

 

The difference may have no effect in some cases, but that is not the same thing.
