在我看来，我有2个按钮，一个按钮的形式用于基于下拉列表过滤数据，另一个按钮用于将过滤的数据导出到Excel。
<?php
$options = array();
$options[0] = 'All';
$options[1] = 'Due last 6 months';
$options[2] = 'Due current month';
$options[3] = 'Due next 3 months';
$options[4] = 'Due next 6 months';
$options[5] = 'Due next 12 months';
?>
<div class="row">
<?= $this->Form->create() ?>
<fieldset>
<div class="row">
<div class="col-xs-3"><?= $this->Form->input('select_period_id', ['options' => $options, 'empty' => false, 'label' => __('Select Period')]) ?></div>
<div class="col-sm-2" style="padding-top:25px;"><?= $this->Form->button(__('Search'), ['class' => 'btn btn-primary']) ?></div>
</div>
</fieldset>
<?= $this->Form->end() ?>
</div>
<div class="timetables index large-9 medium-8 columns content">
<?= $this->Html->link(__('Export to xlsx'), array_merge($this->request->query, ['_ext' => 'xlsx']), ['class' => 'btn btn-primary']) ?>
</div>
我假设第一个按钮是POST，第二个按钮是GET。 我能够通过第一个按钮获得过滤后的数据，但没有第二个按钮：
$data = $this->request->data;
$select_period = $this->request->data('select_period_id');
$today = Time::now()->format('Y-m-d');
$second_date = Time::now();
$assetsAssignations = $this->AssetsAssignations->find()
->contain(['Assets']);
if($this->request->is(['patch', 'post', 'put']))
{
if ($select_period == 0) {
$second_date = $second_date->modify('-6 months');
$second_date = $second_date->format('Y-m-d');
} elseif ($select_period == 1) {
$second_date = $second_date->modify('-6 months');
$second_date = $second_date->format('Y-m-d');
$assetsAssignations->where([
'end_date >=' => $second_date,
'end_date <=' => $today
]);
// etc..
} elseif($this->request->is(['get']))
{
???
}
$_filename = "xls_report_replacement_" . date('Ymd');
$this->set(compact('assetsAssignations', '_filename'));
}
当导出到Excel按钮（GET）时，我找不到我应该放的东西。
请帮忙吗？

我认为，我在表格中添加了第二个按钮：
<div class="row">
<?= $this->Form->create('form_name') ?>
<fieldset>
<div class="row">
<div class="col-xs-3"><?= $this->Form->input('select_period_id', ['options' => $options, 'empty' => false, 'label' => __('Select Period')]) ?></div>
<div class="col-sm-2" style="padding-top:25px;"><?php echo $this->Form->submit('Search', array('name'=>'btn1'))?></div>
<div class="col-sm-2" style="padding-top:25px;"><?php echo $this->Form->submit('Excel', array('name'=>'btn2'))?></div>
</div>
</fieldset>
<?= $this->Form->end() ?>
</div>
当我用第一个按钮调试时：
[
'select_period_id' => '1',
'btn2' => 'Excel'
]
select_period_id = '1'
使用Excel按钮调试：
[
'select_period_id' => '2',
'btn2' => 'Excel'
]
select_period_id = '2'
答案 0 :(得分：1)
在生成xlsx文件时，通过包含调试语句，您正在破坏输出。通过不带任何参数的重定向到test.xlsx，您将丢失已发布的数据。您可能会遇到类似这样的情况：
$this->redirect(['action' => 'test.xlsx', 'select_period_id' => $select_period])
但这很丑。无需重定向，只需将响应类型设置为：
$this->RequestHandler->renderAs($this, 'xlsx');
此外，您有很多重复的代码；大部分可以消除。
通过将日期从Time类切换到Date，在将日期传递给查询生成器之前，您不需要格式化日期。
这是我建议的版本：
{
$data = $this->request->data;
$select_period = $this->request->data('select_period_id');
$today = FrozenDate::now();
$assetsAssignations = $this->AssetsAssignations->find()
->contain('Assets');
// This block could be done with a switch instead of if-elseif
if ($select_period == 0) {
$start_date = $end_date = null;
} elseif ($select_period == 1) {
// Alternately, $start_date = $today->subMonths(6);
$start_date = $today->modify('-6 months');
$end_date = $today;
} elseif ($select_period == 2) {
$start_date = $today;
// Alternately, $start_date = $today->addMonth();
$end_date = $today->modify('1 month');
} elseif ($select_period == 3) {
$start_date = $today;
// Alternately, $start_date = $today->addMonths(3);
$end_date = $today->modify('3 months');
} elseif ($select_period == 4) {
$start_date = $today;
$end_date = $today->modify('6 months');
} elseif ($select_period == 5) {
$start_date = $today;
$end_date = $today->modify('12 months');
}
if ($start_date) {
$assetsAssignations->where([
'Assets.life_end_date >=' => $start_date,
'Assets.life_end_date <=' => $end_date
]);
}
// Personally, I'd rename this from btn2 to something like xlsx, here and in the form template
if (isset($this->request->data['btn2'])) {
$this->RequestHandler->renderAs($this, 'xlsx');
}
$_filename = "xls_report_replacement_" . date('Ymd');
$this->set(compact('assetsAssignations', '_filename'));
}
如您所见，代码短得多，并且在功能上应该相同。
更新：在控制器中，添加顶部：
use Cake\I18n\FrozenDate;
