Re: [PHP-DB] date problems
WOW!! Thanks for all the help guys!! And Instruct ICC.. you're solution for pulling the events did work.. but.. it turns out that the solution was actually much simpler than I thought: The old mysql database (once again, not sure what version) stored the date as MMDDHHMMSS. The new database stores the date as -MM-DD HH:MM:SS. All I had to do was adjust my code to pull only the values and none of the delimeters (ie. "-", " ", and ":"). DUH!!!

"This DID work, but I recently switched hosting companies..." Is the new server in a different country with a different date format / time zone?

Re: [PHP-DB] date problems
From: rDubya <[EMAIL PROTECTED]> Thanks for the help so far guys!! Not helping though. I have the date contained in the database as timestamp (-MM-DD HH:MM:SS). Do you really need to pull events from the database which are not in your range of interest? This will only slow down your processing time. Instead, you could be looping over valid events and not using your incorrect check_date function. If you insist upon using a check_date function on the PHP side (which you claimed to have worked in the past), on the format -MM-DD HH:MM:SS where the first Y is at index 0, then substr($mysql_timestamp, 4, 2) is not the month "MM", it is "-M". You need 5,2. Your other offsets are also wrong. Rather than debugging your check_date function, you should just pull the info you actually need from the database (even to the point of not selecting *, and instead naming specific fields if you really don't need all fields), and remove your check_date function. Then your while loop will loop over only valid events. Also, although this doesn't affect the running of your code, your variable names show a misunderstanding of what parameters you are passing and receiving. $sql = "SELECT..."; $resultResource = mysql_query($sql);// or just $result = mysql_query($sql); if($result != false){ while($event_data = mysql_fetch_assoc($result)) { //Do something with a valid event instead of checking if it is valid now on the PHP side. } } Too bad you are not on MySQL 5, because the SQL query could have been even closer to the phrasing you posted to the list "it is between now and three weeks from now", similar to Mike's reply as: $sql = "SELECT * FROM `EVENTS` WHERE `event_city` = '" . $city . "' AND `theEventDate` BETWEEN NOW() AND DATE_ADD( NOW(), INTERVAL 3 WEEK) ORDER BY `theEventDate` ASC"; But for your MySQL version, WEEK is unavailable and you need INTERVAL 21 DAY (watch the unit versus the expr; DAY not DAYS -- WEEK not WEEKS) http://dev.mysql.com/doc/refman/4.1/en/date-and-time-functions.html#function_date-add http://dev.mysql.com/doc/refman/4.1/en/comparison-operators.html But if you are not familiar with BETWEEN or DATE_ADD, then the way I posted is another way to skin this cat. $sql = "SELECT * FROM `EVENTS` WHERE `event_city` = '" . $city . "' AND TO_DAYS( `theEventDate` ) >= TO_DAYS( NOW() ) AND TO_DAYS( `theEventDate` ) <= TO_DAYS( NOW() ) + 21 ORDER BY `theEventDate` ASC"; http://dev.mysql.com/doc/refman/4.1/en/date-and-time-functions.html#function_to-days And while not trusting your indexing, rewrite short_date as: function short_date ($mysql_timestamp) { return date("D M j", $mysql_timestamp); } or this is probably a 1-liner in the while loop: while...//I'm already using valid events due to my query ... date("D M j", $event_data['theEventDate']) ... _ Test your celebrity IQ.

Re: [PHP-DB] date problems
Thanks for the help so far guys!! Not helping though. I have the date contained in the database as timestamp (-MM-DD HH:MM:SS). The problem is that not only is it not displaying events, but if I alter my code so that it displays ALL events, it shows the events for the last year, and those upcoming, as all being in the first couple weeks of December, 2006. Here is the script in action: http://www.clubandpub.ca/lobby/?city=1 The events SHOULD display on the right column, under where it says events. If you click to the GUIDE page, the calendar should be highlighted on the dates where there are events, and the events in the coming weeks (as well as concerts) should display below that (under their respective headings). This DID work, but I recently switched hosting companies as the one I was with has become increasingly unreliable after the company changed hands. My new server uses PHP 5 server, with MySQL 4.1 (I'm not 100% sure what the old was.. I think it was PHP 4, and while I think it was the same MySQL version, it could have been an earlier one). Cheers! rDubya also, here is the code that actually displays the events: it then displays the event information of the events within that time period (pulled from the database, with the date being displayed using the short_date function posted earlier) On 9/6/07, Mike Gohlke <[EMAIL PROTECTED]> wrote: > > Argh, make sure you add the closing paren for the date_add since I > forgot it. > > Mike... > > Mike Gohlke wrote: > > It's much better to use add_date instead of to_days since mysql isn't > > smart enough to do it for you. > > Such as: > > SELECT yourEventFields FROM theTable > > WHERE theEventDate BETWEEN now() AND date_add(now(), INTERVAL 21 DAYS; > > > > This way mysql will calc the now() and date_add and will essentially > > convert them to static values.
