In the code below, I'm pulling all upcoming training classes from my database. I'm checking to see if the endDate
has passed and I'm also checking if the status !='2'
I want this to return the 4 most recent results. It works fine until status
does =2. I understand that the loop is technically running 4 times, but only displaying the results with status !='2'
How can I change this so that if status = '2'
the loop will continue until it finds 4 results that meet the criteria?
<?php
$today = date("Y-m-d");
$count = 0;
$sth = $dbh->query('SELECT * from training ORDER BY startDate ASC');
$sth->setFetchMode(PDO::FETCH_ASSOC);
while($count <= 4 && $row = $sth->fetch()) {
if($row['endDate'] > $today && $row['status'] != '2') {?>
<li>
<img class="post_thumb" src="/images/img.jpg" alt="" />
<div class="post_description">
<small class="details">
<?php echo date("m/d/Y", strtotime($row['startDate'])) . ' - ' . date("m/d/Y", strtotime($row['endDate'])) ?>
</small>
<a class="post_caption" href="/register.php?course_id=<?php echo $row['courseId'] . '&id=' . $row['id'] ?>"><?php echo $row['title'] ?></a>
</div>
</li>
<?php }
$count++;
}
?>
You must put the $count++
inside the if
loop, otherwise it will always get incremented.
As in:
<?php
$today = date("Y-m-d");
$count = 0;
$sth = $dbh->query('SELECT * from training ORDER BY startDate ASC');
$sth->setFetchMode(PDO::FETCH_ASSOC);
while($count <= 4 && $row = $sth->fetch()) {
if($row['endDate'] > $today && $row['status'] != '2') {?>
<li>
<img class="post_thumb" src="/images/img.jpg" alt="" />
<div class="post_description">
<small class="details">
<?php echo date("m/d/Y", strtotime($row['startDate'])) . ' - ' . date("m/d/Y", strtotime($row['endDate'])) ?>
</small>
<a class="post_caption" href="/register.php?course_id=<?php echo $row['courseId'] . '&id=' . $row['id'] ?>"><?php echo $row['title'] ?></a>
</div>
</li>
<?php
$count++;
}
}
?>
You can break out out of the loop, if its four
while($row = $sth->fetch()) {
....
if($row['status']=='2' && $count >="4") break;
$count++;
}
