If Statement based on Date

How do I modify this where statement to include records with a meeting_date that is either equal to or after today.

'where' => "meeting_date > NOW()"

basically this, which isn't working...
'where' => "meeting_date > NOW() OR meeting_date = NOW()"

Hi,

The MySQL NOW() statements give you the current time stamp to the second. If you're just interested in the day of the meeting (ie, the time of the meeting doesn't matter, you can try something like this:

First, get the current date formatted properly:

$currentDate = date("Y-m-d");

Then set up your WHERE clause like this:

'where' => "meeting_date LIKE '$currentDate%' ",

Hope this helps

so, not exactly...

What I am trying to do is generate a list of upcoming meetings and once a meeting date has passed I want it to no longer appear. But if there is a meeting happening today I do want it to appear. But at the moment they don't appear. I assume this is due to the fact that NOW() is based on the current time to the second and I am not inputting the time for my meetings.

I am looking for something like this...
'where' => "meeting_date > NOW() + 1 DAY",

Hi Zip 222,

I've documented a number of these types of scenarios in the "Working With Dates" section of my CMSB Cookbook http://www.thecmsbcookbook.com

Here's one of the recipes that may help:

COMPARING DATES

When combined with the “if” statement, this extremely useful concept can be used to show or hide fields based on a particular date, automatically archive records after a specified time period and perform many other functions.

Here’s the basic idea of how to compare a date field to today’s date on a list page. This example uses a date field called “opening_reception” in a multi record editor called “exhibitions”. The goal was to automatically hide the opening reception date after the date had passed.

First you’ll need a “foreach” statement to display each record.

_____ code ________________________________________________

<?php foreach ($exhibitionsRecords as $record): ?>

__________________________________________________________

Since dates are normally expressed as months, days and years are hard to compare mathematically, the dates are converted to the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT)

Note that dates are referenced to local time as set in the CMSB “General Settings” information and not server time.

Dave suggested to first define a few variables and to use simple, descriptive names so that the process is easier to follow. Then set some rules for the comparisons. You can use mathematical operators like <, >, <= or >= between values to compare them in different ways.

_____ code ________________________________________________

<?php
$eventUnixTime = strtotime( $record['reception_date'] ); // seconds since 1970
$eventDateString = date("l, F jS", $eventUnixTime); // example format: Monday, June 1st
$currentUnixTime = time();
$currentDateString = date("l, F jS", $currentUnixTime);


$isEventToday = ($eventDateString == $currentDateString); // first comparison
$isEventOver = !$isEventToday && ($eventUnixTime < $currentUnixTime); // second comparison
$isFutureEvent = !$isEventOver && !$isEventToday; // third comparison
?>
__________________________________________________________

Then it becomes a simple matter of comparing the variables

_____ code ________________________________________________

<?php if ($isFutureEvent): ?>
Opening Reception: <?php echo $eventDateString ?>

<?php elseif ($isEventToday): ?>
The Opening reception is today. Don't miss it!!

<?php else: ?>
Sorry, you missed the Opening Reception.

<?php endif; ?>

__________________________________________________________

and don’t forget the endforeach statement to close your loop.

_____ code ________________________________________________

<?php endforeach ?>

__________________________________________________________

Or, Let’s say you want to group a set of meetings by future and past dates

You could use:

_____ code ________________________________________________

<?php foreach ($general_meetingsRecords as $record): ?>
<?php
$eventUnixTime = strtotime( $record['date'] ); // seconds since 1970
$eventDateString = date("l, F jS", $eventUnixTime); // example format: Monday, June 1st
$currentUnixTime = time();
$currentDateString = date("l, F jS", $currentUnixTime);

$isEventToday = ($eventDateString == $currentDateString);
$isEventOver = !$isEventToday && ($eventUnixTime < $currentUnixTime);
$isFutureEvent = !$isEventOver && !$isEventToday;
?>

<?php if ($isEventToday): ?> <p>

<div align="center"class="heading-text-bold">TONIGHT'S MEETING:</div>
</p>
<br /> <span class="body-text-bold"><?php echo date("D, M jS, Y g:i a", strtotime($record['date'])) ?>
</span>
<br />
<div align="left" class="body-text"><?php echo $record['content'] ?></div>
<hr align="left" color="#A29DB2" width="100" /><br />
<?php endif; ?> <?php endforeach ?>
</div>
<p>

<div align="center"class="heading-text-bold">UPCOMING MEETINGS:</div>
</p>
<?php foreach ($general_meetingsRecords as $record): ?>

<?php
$eventUnixTime = strtotime( $record['date'] ); // seconds since 1970
$eventDateString = date("l, F jS", $eventUnixTime); // example format: Monday, June 1st
currentUnixTime = time();
$currentDateString = date("l, F jS", $currentUnixTime);

$isEventToday = ($eventDateString == $currentDateString);
$isEventOver = !$isEventToday && ($eventUnixTime < $currentUnixTime);
$isFutureEvent = !$isEventOver && !$isEventToday;
?>

<?php if ($isFutureEvent): ?>
<br />
<span class="body-text-bold"><?php echo date("D, M jS, Y g:i a", strtotime($record['date'])) ?></span> <br />

<div align="left" class="body-text"> <?php echo $record['content'] ?></div><hr align="left" color="#A29DB2" width="100" />
<?php endif; ?> <?php endforeach ?>
<br />
<p><div align="center" class="heading-text-bold">PAST MEETINGS:</div></p>

<?php foreach ($general_meetingsRecords as $record): ?>

<?php
$eventUnixTime = strtotime( $record['date'] ); // seconds since 1970
$eventDateString = date("l, F jS", $eventUnixTime); // example format: Monday, June 1st
$currentUnixTime = time();
$currentDateString = date("l, F jS", $currentUnixTime);

$isEventToday = ($eventDateString == $currentDateString);
$isEventOver = !$isEventToday && ($eventUnixTime < $currentUnixTime);
$isFutureEvent = !$isEventOver && !$isEventToday;
?>

<?php if ($isEventOver): ?>
<br />
<span class="body-text-bold"><?php echo date("D, M jS, Y g:i a", strtotime($record['date'])) ?></span> <br />


<div align="left" class="body-text"><?php echo $record['content'] ?></div><hr align="left" color="#A29DB2" width="100" />
<?php endif; ?> <?php endforeach ?>
</div>

__________________________________________________________

Note that you have to redefine the variables for each "foreach" loop

If you want to compare other field values, just define more variables and compare those as well.

If you want to test for the values of the variable that you're using. Try something like this in your foreach loop:

_____ code ________________________________________________

<ul>
<li>Event date = <?php echo $eventDateString ?></li>
<li>Current date = <?php echo $currentDateString ?></li>
<li>$isEventToday = <?php echo $isEventToday ? "true" : "false" ?></li>
<li>$isEventOver = <?php echo $isEventOver ? "true" : "false" ?></li>
<li>$isFutureEvent = <?php echo $isFutureEvent ? "true" : "false" ?></li>
<li>$CurrentUnixTime extended = <?php echo date("l jS \of F Y h:i:s A", $currentUnixTime); ?></li>

</ul>
