如何将多个值添加到数组的键中,并从另一个表中获取数据


How to add multiple values to a key of an array and get data from another table?

我试图从一个数据库中获取数据,条件是id等于当前登录的租户(tenant_id),

$this->data['props'] = $this->property_m->get_by( array ('id' => $this->session->userdata['tanant_id'] ));

然后从字段中获取一些值并保存在数组中,

if(count($this->data['props']) > 0){
    $my_array = array();
    foreach ($props as $prop){
        $my_array['id'] = $prop->tenant_id;
    }
}

这里的第一个问题是$my_array只包含一个值。(我需要它是多重的)我该怎么做
第二个问题-我需要从另一个表中选择数据,该表将查找满足该数组中条件的数据,

$this->data['reports'] = $this->report_m->get_by($my_array);

也就是说

SELECT * FROM  reports WHERE ('id = 1'); // or 2 or 3 (value from prop->tenant)

但我需要它,

SELECT * FROM reports WHERE ('id = 1 OR id = 2 OR id = 3'); 

执行:

$my_array = array();
foreach ($props as $prop){
    $my_array['id'] = $prop->tenant_id;
}

您只是在覆盖$my_arrayid密钥。使用此:

$my_array = array();
foreach ($props as $prop){
    $my_array[] = $prop->tenant_id;
}
// print_r($my_array); 

使用where field in ()条件:

SELECT * FROM reports WHERE id IN (1, 2, 3);

假设你有:

$my_array = array(1,2,3);
// query string:
$q_str = 'SELECT * FROM reports WHERE id IN (' . implode(',', $my_array) . ')';
