我的视图中有这样一个列表:
<? foreach($services as $service): ?>
<tr>
<td><?= $service->name; ?></td>
<td><?= $service->format; ?></td>
<td><?= $service->member; ?></td>
<td><?= $service->non_member; ?></td>
</tr>
<? endforeach; ?>
但是我想根据$service->分组将结果分成几个表;所以它看起来类似于:
<h2><?= $service->grouping; ?></h2>
<? foreach($services as $service): ?>
<tr>
<td><?= $service->name; ?></td>
<td><?= $service->format; ?></td>
<td><?= $service->member; ?></td>
<td><?= $service->non_member; ?></td>
<td><?= $service->grouping; ?></td>
</tr>
<? endforeach; ?>
<h2><?= $service->grouping; ?></h2>
<? foreach($services as $service): ?>
<tr>
<td><?= $service->name; ?></td>
<td><?= $service->format; ?></td>
<td><?= $service->member; ?></td>
<td><?= $service->non_member; ?></td>
</tr>
<? endforeach; ?>
Services等于:
$this->data["services"]= $this->services_model->group_by("grouping")->get_all();
是否有一种方法对结果进行分组，并在下一个表循环之前给每个分组一个标题?
您可以遍历$services并根据$service->grouping分隔值。像这样:
<?php
$groupedServices = array();
foreach($services as $service){
if(!isset($groupedServices[$service->grouping])){
$groupedServices[$service->grouping] = array();
}
$groupedServices[$service->grouping][] = $service;
}
然后，当您在视图中打印它时，只需使用2个foreach循环。
<?php foreach($groupedServices as $grouping=>$services): ?>
<tr>
<td colspan="4"><?=$grouping?></td>
</tr>
<?php foreach($services as $service): ?>
<tr>
<td><?=$service->name?></td>
<td><?=$service->format?></td>
<td><?=$service->member?></td>
<td><?=$service->non_member?></td>
</tr>
<?php endforeach; ?>
<?php endforeach; ?>
你也可以使用array_filter作为回调
例如:
<? foreach($services as array_filter($service,function($value) {return $value->grouping == "GROUP1"; }): ?>
<tr>
<td><?= $service->name; ?></td>
<td><?= $service->format; ?></td>
<td><?= $service->member; ?></td>
<td><?= $service->non_member; ?></td>
</tr>
<? endforeach; ?>
