Php 通过过滤器从多个数据库中选择

我的网站url如下所示：

http://example.com/realestate/type-apartament/rooms-3-2/key-value1-value2-value3

[type] => Array
    (
        [0] => apartament
    )

[rooms] => Array
    (
        [0] => 3
        [1] => 2
    )

[key] => Array
    (
        [0] => value1
        [1] => value2
        [2] => value3
    )

Select * from properties a
LEFT JOIN properties_type b
ON a.property_type_id = b.property_type_id
WHERE b.property_type = apartament
AND a.rooms = 3 AND a.rooms = 2

$this->load->model('Filter_model');
$result = $this->Filter_model->model_filter($filter); 

function model_filter($filter)
{
    $this->db->select('*');
    $this->db->from('properties');
    $this->db->join('properties_type', 'properties.property_type_id = properties_type.property_type_id', 'left');
    foreach ($filter as $key => $index) 
    {
        foreach ($index as $number => $value)
            $this->db->where($key => $value);
    }
    $data = $this->db->get()->result_array();

    return $data;
}

从这里我得到一个如下的数组：

http://example.com/realestate/type-apartament/rooms-3-2/key-value1-value2-value3

[type] => Array
    (
        [0] => apartament
    )

[rooms] => Array
    (
        [0] => 3
        [1] => 2
    )

[key] => Array
    (
        [0] => value1
        [1] => value2
        [2] => value3
    )

Select * from properties a
LEFT JOIN properties_type b
ON a.property_type_id = b.property_type_id
WHERE b.property_type = apartament
AND a.rooms = 3 AND a.rooms = 2

$this->load->model('Filter_model');
$result = $this->Filter_model->model_filter($filter); 

function model_filter($filter)
{
    $this->db->select('*');
    $this->db->from('properties');
    $this->db->join('properties_type', 'properties.property_type_id = properties_type.property_type_id', 'left');
    foreach ($filter as $key => $index) 
    {
        foreach ($index as $number => $value)
            $this->db->where($key => $value);
    }
    $data = $this->db->get()->result_array();

    return $data;
}

我的select from db应如下所示：

http://example.com/realestate/type-apartament/rooms-3-2/key-value1-value2-value3

[type] => Array
    (
        [0] => apartament
    )

[rooms] => Array
    (
        [0] => 3
        [1] => 2
    )

[key] => Array
    (
        [0] => value1
        [1] => value2
        [2] => value3
    )

Select * from properties a
LEFT JOIN properties_type b
ON a.property_type_id = b.property_type_id
WHERE b.property_type = apartament
AND a.rooms = 3 AND a.rooms = 2

$this->load->model('Filter_model');
$result = $this->Filter_model->model_filter($filter); 

function model_filter($filter)
{
    $this->db->select('*');
    $this->db->from('properties');
    $this->db->join('properties_type', 'properties.property_type_id = properties_type.property_type_id', 'left');
    foreach ($filter as $key => $index) 
    {
        foreach ($index as $number => $value)
            $this->db->where($key => $value);
    }
    $data = $this->db->get()->result_array();

    return $data;
}

如何根据我拥有的键值生成此select？我唯一想到的解决方案是创建一个数组帮助器，其中包含每个键和相应的表、外键、列

这是我处理url中的过滤器的函数：

if(!function_exists('process_filters')) {

    function process_filters($filters) {
        $data = array();
        foreach($filters as $filter):
            $filter_exploded = explode('-', $filter);
            $val = array_shift($filter_exploded);
            $data[$val] = $filter_exploded;
        endforeach;
        return $data;
    }

}

其中，$过滤器来自控制器方法：

public function index(...$params)

---

我将在

$filter

变量中设置您的筛选器。 然后你需要调用你的过滤器模型。例如，我将确定您的型号名称为

Filter\u model

然后您需要从控制器调用model_filter，如下所示：

http://example.com/realestate/type-apartament/rooms-3-2/key-value1-value2-value3

[type] => Array
    (
        [0] => apartament
    )

[rooms] => Array
    (
        [0] => 3
        [1] => 2
    )

[key] => Array
    (
        [0] => value1
        [1] => value2
        [2] => value3
    )

Select * from properties a
LEFT JOIN properties_type b
ON a.property_type_id = b.property_type_id
WHERE b.property_type = apartament
AND a.rooms = 3 AND a.rooms = 2

$this->load->model('Filter_model');
$result = $this->Filter_model->model_filter($filter); 

function model_filter($filter)
{
    $this->db->select('*');
    $this->db->from('properties');
    $this->db->join('properties_type', 'properties.property_type_id = properties_type.property_type_id', 'left');
    foreach ($filter as $key => $index) 
    {
        foreach ($index as $number => $value)
            $this->db->where($key => $value);
    }
    $data = $this->db->get()->result_array();

    return $data;
}

我不知道你已经走了多远，你有带值的数组吗？还是怎样你能告诉我们你已经做了多少/你尝试了什么吗？我编辑了我的代码，请勾选OK，但是如果我有20个过滤器，我应该加入所有10个表吗？我想只有在应用过滤器的情况下才能加入。和

$this->db->where（$key=>$value）

$key

并非始终与列名相同。是否所有表都始终具有属性\u type\u id？。
