我创建了多个复选框，如下所示。

 $forms  = $this->wondr->m('WApplication.ApplicantForms')->find('list', array('conditions' => array('facility_id' => $this->wondr->facility['Facility']['id']), 'contain' => array()));

    $event->result['forms'] = $event->subject()->Form->input(
            'forms', array(
                'multiple'   => 'checkbox',
                'options' => $forms,
                'class'  => 'form-control',
                'label'  => __('Forms'),
            )
       );

当我选择多个复选框时它工作正常但是当我只选择一个复选框时它会抛出错误

   $forms  = $this->wondr->m('WApplication.ApplicantForms')->find('list', array('conditions' => array('facility_id' => $this->wondr->facility['Facility']['id'],
        'ApplicantForms.id IN '=> $event->data['requestQuery']['forms']
    ), 'contain' => array()));

对于单个 id，CakePHP 会自动将 IN() 转换为 IN = ()。

Error: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '= ('595b5fab-97d4-4c59-a41a-013fac120009')' at line 1

SQL Query: SELECT `ApplicantForms`.`id`, `ApplicantForms`.`name` FROM `wondr`.`applicant_forms` AS `ApplicantForms` WHERE `facility_id` = '58ecb98f-92cc-4a90-a692-0026ac120005' AND `ApplicantForms`.`id` IN = ('595b5fab-97d4-4c59-a41a-013fac120009')

有人可以帮忙吗？

只需更换：

$forms  = $this->wondr->m('WApplication.ApplicantForms')->find('list', array('conditions' => array('facility_id' => $this->wondr->facility['Facility']['id'],
    'ApplicantForms.id IN '=> $event->data['requestQuery']['forms']
), 'contain' => array()));

经过：

$forms  = $this->wondr->m('WApplication.ApplicantForms')->find('list', array('conditions' => array('facility_id' => $this->wondr->facility['Facility']['id'],
    'ApplicantForms.id'=> (array)$event->data['requestQuery']['forms']
), 'contain' => array()));

换句话说，删除IN并确保它$event->data['requestQuery']['forms']是一个数组（如果你有疑问，你可以先var_dump处理它）。
