Question

$data是一个数组，其中包含订单表中提取记录的用户发布数据

$data=array('customer_id'=>$this->input->post('custId'),'paided'=>2);
$this->db->select('*');
$this->db->from('orders');
$this->db->where($data);
$this->db->get();

Answer 1

$data = array(
    'customer_id'       =>      $this->input->post('custId')],
    'paided'            =>      2   
);

$this->db->select('*');
$this->db->from('orders');
$this->db->where($data);

$this->db->get();

Answer 2

试试这个：

public function function_name (){
 $data = array (
    'customer_id' => $this->input->post('custId'),
    'paided'      => 2
 );

 $this->db->select('*');
 $this->db->from('ordere');
 $this->db->where($data);

 $query = $this->db->get();
 return $query->result_array();
}

Answer 3

如果你得到一行，你已经做了所有好事只需要放置result（）如果你得到多行

$data=array('customer_id'=>$this->input->post('custId'),'paided'=>2);
$this->db->select('*');
$this->db->from('orders');
$this->db->where($data);
$result= $this->db->get()->result(); //added result()
print_r($result);

Answer 4

这是使用框架的好处，你不需要编写那么多代码，

$where = array('customer_id' => $this->input->post('custId'),'paided'=>2)

$result = $this->db->get_where('orders', $where);

并且要获取它们，请使用$result->row()进行单个记录检索。

如果您想要所有记录，请使用$result->result()

Answer 5

简单使用

$custId = $_post['custId'];

$query = $this->db->query("SELECT * FROM orders WHERE customer_id= '$custId'  AND paided='2'");
$result = $query->result_array();
return $result;//result will be array

Answer 6

你需要做什么以及为什么

$data=array('customer_id'=>$this->input->post('custId'),'paided'=>2);
$this->db->select('*'); // by defaul select all so no need to pass *
$this->db->from('orders');
$this->db->where($data);
$this->db->get(); // this will not return data this is just return object

所以你的代码应该是

$data=array('customer_id'=>$this->input->post('custId'),'paided'=>2);
$this->db->select(); // by defaul select all so no need to pass *
$this->db->from('orders');
$this->db->where($data);

$query = $this->db->get();
$data = $query->result_array();
// or You can 
 $data= $this->db->get()->result_array();

此处result_array()返回纯数组，您也可以使用result() 这将返回对象数组
