php - 如何在 CakePHP 3.2 中设置条件？

Question

在 CakePHP 3.2 中从数据库中获取数据时，如何将条件放入查询中。这里我实现了一个分页，很容易通过 WHERE 条件（见下面的代码）。

public $paginate = [
        'fields' => ['Users.id', 'Users.email', 'Users.name', 'Users.is_active'],
        'limit' => 1,
        'conditions'=>['Users.is_active' =>1],
        'order' => [
            'Users.id' => 'asc'
        ]
    ];

public function index() {
        $users = $this->paginate($this->Users);
        $this->set(compact('users'));
    }

在上面的代码中我使用了分页，所以我很容易传递条件和其他东西，比如字段、顺序等。

如果分页不存在，那么代码是什么？这里我只需要从数据库中取数据，然后给出条件和其他东西。在 CakePHP 2.6 中，代码如下所示。

  $this->EventCategory->find('all', array('conditions' => array('EventCategory.is_active' => 1), 'fields' => array('EventCategory.id', 'EventCategory.name')));

在 CakePHP 3.2 中有没有其他方法可以像上面那样（没有分页）？

欢迎任何建议。先感谢您。

请阅读文档http://book.cakephp.org/3.0/en/orm/retrieving-data-and-resultsets.html

$query = $this->EventCategory->find('all')
    ->select(['EventCategory.id', 'EventCategory.name'])
    ->where(['EventCategory.is_active' => 1]);

在控制器中使用此代码

$con=[];
$con['Users.role_id'] = 3;

  if (isset($this->request->query['keyword']) && !empty($this->request->query['keyword'])) {
            $keyword = trim($this->request->query['keyword']);
            $con['OR'] = ['Users.phone LIKE' => '%' . $keyword . '%', 'Users.name LIKE' => '%' . $keyword . '%', 'ContractorDetails.company_name LIKE' => '%' . $keyword . '%', 'ProjectTypes.name LIKE' => '%' . $keyword . '%'];
        }

 $this->paginate = [
            'sortWhitelist' => ['ContractorDetails.company_name', 'ProjectTypes.name', 'Users.name', 'Users.id', 'Users.phone', 'Users.deleted', 'Users.probationary'],
            'contain' => ['ContractorDetails.ProjectTypes'],
            'conditions' => $con,
            'order' => ['Users.id' => 'desc'],
            'limit' => (isset($this->request->query['limit'])) ? $this->request->query : 10,
        ];
        $users = $this->paginate($this->Users);

        $this->set(compact('users'));

在 view.ctp 中使用它

use Cake\Core\Configure;
use Cake\I18n\Number;
    <div class="row">
                <div class="col-sm-6">
                    <div class="dataTables_info" id="editable_info" role="status" aria-live="polite"><?= $this->Paginator->counter(['format' => 'Showing {{start}} to {{end}} of {{count}} contractors']) ?></div>
                </div>
                <?php if ($this->Paginator->counter(['format' => '{{pages}}']) > 1) { ?>
                    <div class="col-sm-6">
                        <div class="dataTables_paginate paging_bootstrap" id="editable_paginate">
                            <ul class="pagination pull-right">
                                <?= $this->Paginator->prev('Previous') ?>
                                <?= $this->Paginator->numbers() ?>
                                <?= $this->Paginator->next('Next') ?>
                            </ul>
                        </div>
                    </div>
                <?php } ?>
            </div>
