AND/OR operators

[NHStars]

I'm working on a code to validate some data through a post form...my problem is that I'm trying to figure out if both of my variables are empty or not.

it's basically something like this

[color=red]$ef = $_POST['f'];
$es = $_POST['s'];

if (!$ef [color=green]AND[/color] !$es) {

code here blah blah

}
[/color]

Being that I come from a background of Visual Basic programming, I figured I'd try this. Now I can't seem to find out what the PHP equivalent is. Same with OR in place of AND. Anything you guys can tell me is appreciated. Thanks in advance.

[code]if ($ef == "" && $es == "") {[/code]

when posting forms all the fields (except unchecked radio buttons/checkboxes are set - even if they are null or empty.

you best option is

if (empty($ef) && empty($es))

....

<?php

if(empty($ef) || empty($es)) {
  // Do stuff
}
?>
[/code]

The problem with checking to see if the field is empty with the empty() function is that if the field contains the single character "0" the function emtpy() will return "true". I use the following to see if the field is emty:
[code]<?php
if (strlen(trim(stripslashes($_POST['fld']))) == 0) echo 'The field is emtpy';
?>[/code]
