(Apologies for cross-postings here but I lost a php-db list members personal email
address..)
I need a query that in English would read something like:
"Select all records from table: 'items' where each record is displayed for 7days after
it's
submission."
It was suggested I may have to modify the output of now() to match my MySQL DB
'submitDate' field
as in the query below:
$sql = "SELECT * FROM $tabitem WHERE DATE_ADD(submitDate, INTERVAL 7 DAY) =
now()";
So I tried the following:
$sql = "SELECT * FROM $tabitem WHERE DATE_ADD(submitDate, INTERVAL 7 DAY) =
DATE_FORMAT(NOW(),'Y-M-D')";
MySQL didn't complain but nor did it print out all postings submitted in the last
seven days which
is what it is suppposed to be doing!
The 'submitDate' field is a MySQL DATE field and I'm using MySQL-3.22.32 if that's any
use.
Why is the query not doing what it's told!!?
Cheers for your help thus far!

Depending on how the date is stored (date + time, or just date)
