"" blank field?

[Bickey]

I'm confused...

 

how do you say check if the field in MYSQL is blank? it's not getting what I'm attempting to get. Please help.

 

I want to do actionA... if either of these 3 conditions are true

tf1=="RED"

tf1==""

tf2=="" AND tf=="apple"

 

 

if(tf1=="RED" or tf1=="" or tf2=="" AND tf=="apple")
{
do actionA...
}

How do you know?  Did you output any of these variables to see what the actual value is?

 

As far as your logic, I think you want:

if((tf1=="RED" or tf1=="" or tf2=="") AND tf=="apple")

the variables output is correct. But I think my code is causing problems.

 

when I test with the first 2 conditions it works but when I add the 3rd condition it doesn't give the desired output. ... in the 3rd condition I want check if tf2 is blank AND tf says apple (both should be true in the 3rd condition).

Then you have to group the logic together with parentheses:

if(tf1=="RED" or tf1=="" or (tf2=="" AND tf=="apple"))

You just need to add the parenthsis around the last two conditions:

 

<?php
if($tf1=="RED" or $tf1=="" or ($tf2=="" and $tf=="apple")) {
?>
