我将一个2.5应用程序迁移到cakePHP 3.0,我正在更新我的代码以使用find()
之后的ORM对象而不是数组。
在我的2.5视图中,我做一个数组查找并计算结果。但是我似乎无法访问我需要在新代码中进行计数的对象级别。
2.5代码:
<?php foreach ($recentEmployees as $recentEmployee): ?>
<tr>
<td>
<?php echo ($recentEmployee['Employee']['name']); ?>
</td>
<td><?php echo h($this->Time->format('d/m/Y', $recentEmployee['Employee']['created'])); ?></td>
<td>
<?php
$completedCourses = count(
array_filter(
$recentEmployee['Course'],
function($item){return $item['CoursesEmployee']['completed'];}
)
);
$totalCourse = count($recentEmployee['Course']);
?>
<span class="label <?php echo($label); ?>">
<?php
echo ($completedCourses);
?>
/<?php echo ($totalCourse); ?>
</td>
</tr>
<?php endforeach; ?>
现在我的3.0代码和对象,我正在尝试访问和计数:
<?php foreach ($recentEmployees as $recentEmployee): ?>
<tr>
<td><?= h($recentEmployee->name) ?></td>
<td><?= h($this->Time->format($recentEmployee->created, 'd/M/Y')) ?></td>
<td><?= debug($recentEmployee->courses) ?></td>
</tr>
<?php endforeach; ?>

我已经试过了,但它是一个糟糕的混乱的对象和数组
$completedCourses = count(
array_filter(
$recentEmployee->courses,
function($item){return $item['CoursesEmployee']['completed'];}
)
);
* * * *更新我通过指向_jointable来访问数据。这肯定不是最佳实践吧?
<?= $completedCourses = count(
array_filter(
$recentEmployee->courses,
function($item){return $item['_joinData']['completed'];}
)
);?>
对我来说似乎没问题,但是你可以在你的操作代码中通过查找来计数。
要避免连接,可以使用对象访问方法…
<?= $completedCourses = count(
array_filter(
$recentEmployee->courses,
function($item){return $item->completed;}
)
);?>
