What file are you seeing this in?

Sorry for the delay getting to this as it was not a priority item.

The code is actually correct.

if ((strlen($eventdata[0]->early_disc) > 0) && (strtotime($eventdata[0]->early_disc_date) > strtotime(date(“Y-m-d”) . ” -1 day”))) {
// apply earley bird discount here
}

What this code is saying is:

IF early_disc value exists AND early_disc start date IS GREATHER THAN yesterday THEN apply early bird discount.

So let’s examine that last part “AND early_disc start date is GREATHER THAN yesterday” a little bit more, by actually throwing a date in there.

If we wanted our early bird discount to start on November 10, 2012, then that last bit of code would read like this:

AND Nov 10, 2012 IS GREATHER THAN Nov 9, 2012

which would be TRUE and your discount would be applied.

IF we did NOT subtract a day then it would read

AND Nov 10, 2012 IS GREATHER THAN Nov 10, 2012

which would be FALSE and your discount would NOT be applied, and would NOT be applied until Nov 11, 2012, which of course is not when we want it to begin.

Instead of subtracting a day, it maybe would have been easier to understand if it had been coded using >= “greater than or equals” ala:

AND Nov 10, 2012 IS GREATHER THAN OR EQUAL TO Nov 10, 2012

but ultimately it all reads the same.

Make sense now?
