Re: Help with If else if

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


No Michael, your code is also not working. What you have understood is
correct. let me explain it to others too.

If variable twitter and facebook are empty don't echo anything,

if variable twitter has a value and facebook is empty echo out only twitter,

if variable twitter has no value and facebook has a value echo out facebook
only,

and finally if both has values echo out both.

Basically I want to echo out only if there is some value in the database.
But in my case both the images are echoing out.
