php if statement

[JWH_Matthew]

Hey guys,
I am working on my plugin, and I cant figure this out:
I would like to create an if statement within an if statement, does this make sense?

I want it to look like this:

Code:

if (condition = 'condition') {
    if (2nd condition = '2 condition') {
       code to be executed
    }
}

Is this right, if so why doesn't it work for me:/ and if not, how can i do this?

Thanks
