此处客户A和客户B向一个供应商发送消息，供应商单击客户A消息，仅打开特定客户A消息

Question

此处客户A 和客户B 向一个供应商发送消息，供应商点击客户A 消息，并且只想打开特定的客户A 消息不会混合它们。但是我收到来自客户A和客户B的消息的输出。请帮我解决这个问题。

模型

[public function customer_to_supply() {
        $this->db->select('*');
        $this->db->from('communication');
        $this->db->join('supplier_otherdetails', 'supplier_otherdetails.supplierid_fk = communication.supplier_id');
        $this->db->join('customer_registration', 'communication.Customer_id=customer_registration.id');
        //$this->db->join('communication', 'communication.product_id=contact_supplier.product_id');
        $where = "communication.From' =>'customer'";
        $this->db->where($where);
        $query = $this->db->get();
        $results = \[\];
        if ($query->num_rows() > 0) {

            $results = $query->result();
        }
        return $results;
    }

控制器

    public function supplier_communication() {



     $supp_id = $this->input->post('suppid');
     $product_id = $this->input->post('proid'); 
     $cust_id = $this->input->post('custid');
     $this->session->userdata('cust',$cust_id);



    $result1 = $this->Profile_model->fetch_Data($product_id);
    $Userid = $this->session->userdata('id');
    $result3 = $this->session->userdata('tt');
    $data3 = array(
        'message' => $this->input->post('messagee'),
        'supplier_id' => $supp_id,
        'product_id' => $product_id,
        'Customer_id' => $cust_id,
        'From' => $result3,
    );
    $this->Profile_model->data_insertt($data3);

     redirect('welcome/messageview');
}

您必须将客户的ID（$ customer_id）传递给您的模型函数。以下是您重新设计的功能：

public function customer_to_supply($customerId) {
        $qry = $this->db->select('*')
                ->from('communication')
                ->join('supplier_otherdetails', 'supplier_otherdetails.supplierid_fk = communication.supplier_id')
                ->join('customer_registration', 'communication.Customer_id=customer_registration.id')
                ->where('communication.From', 'customer')
                ->where('communication.Customer_id', $customerId)
                ->get();
        if ($qry->num_rows() > 0)
            return $qry->result_array();
        return FALSE;
}
