在 CakePHP 中使用“或”查找

Question

我正在使用 CakePHP 3.2 和 find()。

if($filter_data_array['age_younger'] != '')
        {
            $conditions["icases.age <= "] = $filter_data_array['age_younger'];
        }

        if($filter_data_array['age_older'] != '')
        {
            $conditions["icases.age >= "] = $filter_data_array['age_older'];
        }

        if($filter_data_array['go_date_after'] != '')
        {
            $conditions["icases.go_date >= "] = $filter_data_array['go_date_after'];
        }

        if($filter_data_array['go_date_before'] != '')
        {
            $conditions["icases.go_date <= "] = $filter_data_array['go_date_before'];
        }

        if($filter_data_array['client'] != '')
        {
            $conditions["icases.client_id = "] = $filter_data_array['client'];
        }

        if($filter_data_array['case_name'] != '')
        {
            $conditions["icases.name = "] = $filter_data_array['case_name'];
        }

        if($filter_data_array['case_ref'] != '')
        {
            $conditions["icases.case_reference_i_d = "] = $filter_data_array['case_ref'];
        }

        if($filter_data_array['instruction_date'] != '')
        {
            $conditions["icases.date_instruction_received >= "] = $filter_data_array['instruction_date'];
        }

        $cases_data = TableRegistry::get('icases')->find('all')
                ->select(['icases.id', 'icases.state', 'icases.client_id', 'icases.name', 'icases.age', 'icases.case_reference_i_d', 'icases.go_date', 'clients.name'])
                ->innerJoin('icases_users', 'icases_users.icase_id = icases.id')
                ->where($conditions)
                ->innerJoin('clients', 'clients.id = icases.client_id')
                ->order(['clients.name' => 'ASC', 'icases.name' => 'ASC'])
                ->execute()
                ->fetchAll('assoc');

现在 icases 表中有一个状态列，我想过滤

icases.state='active' OR icases.state='pending' OR icases.state='archive'

我的问题是如何将它集成到我现有的 $conditions 数组中？

提前谢谢你。

Answer 1

我认为你应该使用 cake 提供的Advanced Conditions。据我了解，第一个示例适合您的需要。

所以你应该在执行查询之前添加这个

$conditions['OR'] = [['icases.state' => 'active'], ['icases.state' => 'pending'], ['icases.state' => 'archive']];

Answer 2

这里是找到所有匹配OR 条件的解决方案

$conditions = [];     #For storing all of your conditions as an array

if($filter_data_array['age_younger'] != ''){
    $conditions[]["icases.age <= "] = $filter_data_array['age_younger'];
}

if($filter_data_array['age_older'] != ''){
    $conditions[]["icases.age >= "] = $filter_data_array['age_older'];
 }

if($filter_data_array['go_date_after'] != ''){
    $conditions[]["icases.go_date >= "] = $filter_data_array['go_date_after'];
}

if($filter_data_array['go_date_before'] != ''){
    $conditions[]["icases.go_date <= "] = $filter_data_array['go_date_before'];
}

if($filter_data_array['client'] != ''){
    $conditions[]["icases.client_id = "] = $filter_data_array['client'];
}

if($filter_data_array['case_name'] != ''){
    $conditions[]["icases.name = "] = $filter_data_array['case_name'];
}

if($filter_data_array['case_ref'] != ''){
    $conditions[]["icases.case_reference_i_d = "] = $filter_data_array['case_ref'];
}

if($filter_data_array['instruction_date'] != ''){
    $conditions[]["icases.date_instruction_received >= "] = $filter_data_array['instruction_date'];
}

$cases_data = TableRegistry::get('icases')->find('all')
        ->select(['icases.id', 'icases.state', 'icases.client_id', 'icases.name', 'icases.age', 'icases.case_reference_i_d', 'icases.go_date', 'clients.name'])
        ->innerJoin('icases_users', 'icases_users.icase_id = icases.id')
        ->where(['OR'=>$conditions])   #All of your `OR` conditions here
        ->innerJoin('clients', 'clients.id = icases.client_id')
        ->order(['clients.name' => 'ASC', 'icases.name' => 'ASC'])
        ->execute()
        ->fetchAll('assoc');

注意：您的代码已更改为 -

$conditions[INDEX] to $conditions[][INDEX]

与

->where($conditions) to ->where(['OR'=>$conditions])

首先，我建议关注CakePHP Conventions。您的代码将变得更具可读性。

我还建议在 Table 对象中使用 connect your relations。这使您的代码保持干燥，您可以使用 contain 加载关联的模型，而不是使用 innerJoin '手动'。

查看以下代码。它没有经过测试，但应该可以工作。使用Advanced conditions 有点“蛋糕式”并且易于维护。如果你不关心其余的，只需看一下代码中的$orConditions。

$query = TableRegistry::get('Cases')->find('all')
    ->select([
        'Cases.id', 
        'Cases.state', 
        'Cases.client_id', 
        'Cases.name', 
        'Cases.age', 
        'Cases.case_reference_i_d', 
        'Cases.go_date', 
        'Clients.name'
    ])
    ->order([
        'Clients.name' => 'asc', 
        'Cases.name' => 'asc'
    ])
    ->contain([
        'Clients',
        'Users'
    ])
    ->where(function ($exp) use ($filter_data_array) {

        if (!empty($filter_data_array['age_younger'])) {
            $exp = $exp->lte('Cases.age', $filter_data_array['age_younger']);
        }
        if (!empty($filter_data_array['age_older'])) {
            $exp = $exp->gte('Cases.age', $filter_data_array['age_older']);
        }
        if (!empty($filter_data_array['go_date_after'])) {
            $exp = $exp->gte('Cases.go_date', $filter_data_array['go_date_after']);
        }
        if (!empty($filter_data_array['go_date_before'])) {
            $exp = $exp->lte('Cases.go_date', $filter_data_array['go_date_before']);
        }
        if (!empty($filter_data_array['client'])) {
            $exp = $exp->eq('Cases.client_id', $filter_data_array['client']);
        }
        if (!empty($filter_data_array['case_name'])) {
            $exp = $exp->eq('Cases.name', $filter_data_array['case_name']);
        }
        if (!empty($filter_data_array['case_ref'])) {
            $exp = $exp->eq('Cases.case_reference_i_d', $filter_data_array['case_ref']);
        }
        if (!empty($filter_data_array['instruction_date'])) {
            $exp = $exp->gte('Cases.date_instruction_received', $filter_data_array['instruction_date']);
        }

        $orConditions = $exp->or_([
            'Cases.state' => 'active',
            'Cases.state' => 'pending',
            'Cases.state' => 'archive'
        ]);

        return $exp->add($orConditions);
    });

$cases_data = $query->execute();
