Php 如何使用codeigniter在单视图页面中维护两个表数据

[！[enter image description here][1][1][enter image description here][2]我有两个表invoice和invoice\u description，两个表的

invoice\u no

列都是通用的，我想从

invoice

表名、地址、，发票号和下一个表

发票描述

我想获取产品描述、数量、价格等信息。
这是我的桌子结构

                        invoice
         --------------------------------------
          name   bill_no   invoice_no   address    price
           adi     1        2           adasdasd     12
           abc     2        3           adasdas       13


                       invoice_description
        -----------------------------------------------------
               product   invoice_no  quantity 
                a          2          1
                b          2          2
                c          3          3

     i wana output like when i pass invoice_no 2
               invoice_no:-2     name- adi
                product          quantity
                 a                 1
                 b                 2

这是我的控制器：-

public function invoice($id)
{
            //echo $id;
        $this->load->database();  
             //load the model  
        $this->load->model('useradmin');  
            //$invoice=$this->useradmin->selectdealer($id);  
            //$invoicedes=$this->useradmin->selectdealer1($id);  
            //$data['invoice']=$invoice;
            //$data['invoicedes']=$invoicedes;
            //$this->load->view('envoice',$data);  
          //
        $query = $this->useradmin->selectdealer($id);
        $ids = $this->useradmin->selectdealer1($id);  
        $data['dealers'] =  $query;
        $data['id'] = $ids;                     
        $this->load->view('envoice',$data);
    }

}

public function selectdealer($id)  
{  
    //data is retrive from this query  
    //echo $id;           
    //$this->db->select('*');  
    //$this->db-from('invoice_description');
    $this->db->where('invoice_no', $id);
    $query = $this->db->get('invoice_description');
    return $query->result();
}   
public function selectdealer1($id)  
{  
    //data is retrive from this query  
    //echo $id;
    $query = $this->db->get('invoice');  
    $this->db->where('invoice_no', $id);
    return $query->result();    
}   

我的型号是：-

public function invoice($id)
{
            //echo $id;
        $this->load->database();  
             //load the model  
        $this->load->model('useradmin');  
            //$invoice=$this->useradmin->selectdealer($id);  
            //$invoicedes=$this->useradmin->selectdealer1($id);  
            //$data['invoice']=$invoice;
            //$data['invoicedes']=$invoicedes;
            //$this->load->view('envoice',$data);  
          //
        $query = $this->useradmin->selectdealer($id);
        $ids = $this->useradmin->selectdealer1($id);  
        $data['dealers'] =  $query;
        $data['id'] = $ids;                     
        $this->load->view('envoice',$data);
    }

}

public function selectdealer($id)  
{  
    //data is retrive from this query  
    //echo $id;           
    //$this->db->select('*');  
    //$this->db-from('invoice_description');
    $this->db->where('invoice_no', $id);
    $query = $this->db->get('invoice_description');
    return $query->result();
}   
public function selectdealer1($id)  
{  
    //data is retrive from this query  
    //echo $id;
    $query = $this->db->get('invoice');  
    $this->db->where('invoice_no', $id);
    return $query->result();    
}   

我想从

发票

表中获取发票号、名称和地址 以及

发票\u说明

表中的多个产品说明

我正在尝试我的查看页面是

发票号：-123 名称：-xyzx

产品价格数量 asdaf 12 10 控制器中的asafsa 12 13

//Assign empty array $data and assign a results to the respective array
$data['invoice_description_data']= $this->useradmin->selectdealer($id);
$data['invoice_data'] = $this->useradmin->selectdealer1($id); 
$this->load->view('envoice',$data);     

鉴于

//call 
print_r($invoice_data);
print_r($invoice_description_data);

内部控制器

public function invoice($id)
{
    $this->load->database();  
    $this->load->model('useradmin');  
    $data['dealer'] = $this->useradmin->selectdealer($id);
    $this->load->view('envoice',$data);
}

模型中

public function selectdealer($id)  
{  
    $this->db->select("name, address, invoice_no");
    $this->db->from('invoice');
    $this->db->where('invoice_no', $id);
    $result = $this->db->get()->row_array();
    return $result;
}   

鉴于

foreach($dealer as $row){
    echo $row['name'];
    echo $row['address'];

        $query = $this->db->get_where('invoice_description', array('invoice_no' => $row['invoice_no']));
$results = $query->result_array();
print_r($results);
    foreach($results as $desc){
        echo $desc['quantity'];
        echo $desc['price'];
        echo $desc['desc'];
    } 
}

使用join从两个表中检索数据

foreach($row as $invoicedata){   
    display your data here
}

此项工作用于正确输入发票名称 但是这一行有错误

$query = $this->db->get_where('invoice_description', array('invoice_no' => $row['invoice_no']))->result_array();
print_r($query);

这些功能对我来说是正确的谢谢朋友aap徽标ko mare help karne kaye liye

选择所有代码并按ctrl-k使其正确缩进打印（$invoice\u data）；返回表中的所有行，我只找到一个匹配的行id@AdiSingh在模型中，使用联接和返回结果单行，然后打印$data['DELERS']=$query$数据['id']=$id；只有一个$data可以正常工作$data['id']返回表i上的所有值。我只会传递一个$id，但它不能正常工作。请发送一些演示suneelkumarprint\r（$invoice\u data）；它返回第i行的所有数据，其中只有一行在idit中匹配。它返回表$data['invoice\u description\u data']=$this->useradmin->selectdealer（$id）中的所有数据$数据['invoice\u data']=$this->useradmin->selectdealer1（$id）$data['invoice_data']=返回所有数据$q=$this->db->get（）$结果=$q->row_数组（）；viewforeach（$invoicedata行）怎么样{

   public function selectdealer($id)  
    {  
     if(!empty($id))
         {
    $this->db->where('invoice_no', $id);
    $query = $this->db->get('invoice');
    return $query->result();  
         }
    }   
   public function selectdealer1($id)  
     {  

     if(!empty($id))
        {
            $this->db->where('invoice_no', $id);
         $query = $this->db->get('invoice_description');  
        return $query->result();  
     }  
  }
