[Resolved] If Or? ? ? ? ??

[jcantrell]

alright, here's a simple one. Why does this not work?

if ($a_row[type] != "MEC" OR $a_row[type] != "PLM")
{
Link
}

I know I can do this:

if ($a_row[type] != "MEC")
{
if($a_row[type] != "PLM")
{
LINK
}
}

But I really don't want to do it that way. I've tried !== on the top if statement too.. Any help would be very helpful 🙂

if ($a_row[type] != "MEC" || $a_row[type] != "PLM")
{
Link
}

use || instead of 'OR'

Tried that, still no dice..

[kevinsequeira]

if ($a_row[type] != "MEC" OR $a_row[type] != "PLM")
{
Link
}
ex :
type = MEC
$a_row[type] != "MEC" = false
$a_row[type] != "PLM" = true

so OR evaluates to TRUE, shows links

type = XXX
$a_row[type] != "MEC" = true
$a_row[type] != "PLM" = true

so OR evaluates to TRUE, shows links

BUT

if ($a_row[type] != "MEC" AND $a_row[type] != "PLM")
{
Link
}

type = MEC
$a_row[type] != "MEC" = false
$a_row[type] != "PLM" = true

so AND evaluates to FALSE, doesnt show link

type = XXX
$a_row[type] != "MEC" = true
$a_row[type] != "PLM" = true

so OR evaluates to TRUE, shows links

so when using != , use AND instead of OR

Actually, that if statement will ALWAYS return the link. Try using && instead. And I would suggest using parenthesis:

if (($a_row[type] != "MEC") && ($a_row[type] != "PLM"));

[edit]doh! looks like kevin answered before I could post... but hopefully you understand what we're saying, right?[/edit]

THANK YOU SO MUCH..

I'm a freakin moron. I must have been sick the day they taught If Statements in BASIC..
