[RESOLVED] Why doesn't this if condition work? && || problem ?

ManWithNoName

I need to know if the following condition is correctly defined or not:


if( ($x == 'string 1' && $y == 'string 2') || 
    ($x == 'string 1' && $y == 'string 2' &&
     object && object == object_type ) )

I figure that it says if match xy or (xy and object^2), it seems that it doesn't. The first condition will always match (xy) while the second won't.

If I remove the first xy condition the if statement will match the second condition and the first condition when the first condition also match the object² condition.

I'm I making any sense? If so, please explain to me what I'm doing wrong...

If the first string check is true, it will return true without doing any further test.

I think what you want is

if( ($x == 'string 1'  &&  $y == 'string 2' && object == object_type ) )

This will be true if the 3 tests are TRUE.

... I think that was what I wanted to know.

Basically what I wanted to do was to execute a function for two different conditions within one if statement; now I see the folly of my foolishness stupidity.

Then how would one go about to create two different statements to execute the same function, do I have to create two separate if statement each after another? And is the only other alternative to create a switch with no breaks... ? I'm going to try that...

if( ($x == 'string 1'  &&  $y == 'string 2' && object == object_type ) )  {
// do something
} elseif ( $x == 'string 1'  &&  $y == 'string 2' ) {
// do something else
}

hehe, you must think I'm a complete idoi--newbie cough

Yes, I know I can do that, the problem is that both those statement run the exact same function. I should have been more more clear about this:

if() else if()
run function

something like that, so I do not have to copy the same function twice.

A more correct condition statement would be: if(xy&!object²⁾ or if(xy&object²⁾ (otherwise the first condition would always return true for both conditions; don't ask me why they are differentiated)

I didn't get around to try the switch statement, so I'm going to give it a swing

if( ($x == 'string 1' && $y == 'string 2') || (object == object_type ) )

Is that what you mean?
The syntax in your last post was most confusing.

I am not that judgemental. 🙂

HalfaBee The syntax in your last post was most confusing. (rofl) yes that is why I'm going insane. (Oh, that and the fact I didn't type it correctly; I updated the entry).

Well, I fixed it, it was -- as I suspected all along ^_ -- not related to the if statement.

It seems that I mixed up some variables making the executed function get its values from a previous entry, thus making it look like the condition didn't match (because the old values were used).

... My head spinz...

HalfaBee: you receive an award for best attempted assistance to an insanely loopy question. You may thank the academy now.

PS. I haven't slept for a very long time. That's a valid excuse, isn't it?
