choosing a date

Hi there,
I'm trying to create a sql statement in which a date is compared to another
date and depending on the comparison one is chosen.
such as:

if (date_add(cur_date(), interval 30 day) >=
'$thisDate','$this->date',date_add(cur_date(), interval 30 day)

So: if the current date plus 30 days is larger than thisDate then thisDate
is used, else the date plus 30 days is used.
But: it doesn't do what I expected it to do. Can anybody pint out the
reason. No error message or so ...

Thanks, Sjef

So what DOES it do?

I can't pint it out, but I might be able to point it out.

I have to say that I'm amazed that you didn't get an error as there is a
closing bracket missing.

The result was the date plus 30 days

Please do not top post (top posting fixed).

That is strange, I would have expected an error as there is a bracket
missing.

Can you echo the query as it would have been executed, so we can see what
'$thisDate' resolves to.

We can also understand how an if statement with an obvious syntax error
manages to run!

OK, I found out that the function does not accept dates as 2008-1-10. When
the date is formatted as 2008-01-10 than the function works flawlessly. I
have finally used the LEAST function to choose between the two dates.
Thanks
