传递关联数组以使用 foreach 查看和访问其中的值 - passing associative array to view and accessing values in it using foreach

passing associative array to view and accessing values in it using foreach

本文关键字：访问 foreach 关联数组 | 更新日期: 2023-09-27

这是我在控制器中的代码...

function print_dm($delivery_memo_id){
    $data1=array();
    $query=$this->db->query("select de.*, pr.* from phppos_delivery_memo de inner join 
    phppos_productdetails pr  on de.delivery_memo_id=pr.delivery_memo_id WHERE 
     de.delivery_memo_id=$delivery_memo_id");
    if($query->num_rows() > 0)
  {
  foreach ($query->result() as $row)
  {
    $data1[]=$row->product_id;
    $data1[]=$row->product_name;
    $data1[]=$row->quantity;
    $data1[]=$row->unit;
    $data1[]=$row->unit_rate;

  }
}
else
{
$data1 = array();
 }
 $this->load->view('delivery_memo/print_layout',$data1);
}

当我print_r $data 1时，我得到了这个..

 Array ( [0] => 1 [1] => Zinc Sulphate [2] => 1 [3] => 1 [4] => 100 [5] => 4 [6] => Copper 
 Sulphate [7] => 1 [8] => 12 [9] => 100 [10] => 9 [11] => Sulphur 80% WDG [12] => 1 [13] => 1 
 [14] => 100 )

我把它传给上面的样子。但是我如何在那里访问它还是应该更改控制器中的代码？

我在该数组中获得了多条记录

只需将查询结果传递给视图：

function print_dm($delivery_memo_id){
    $data1=array();
    $query=$this->db->query("select de.*, pr.* from phppos_delivery_memo de inner join 
    phppos_productdetails pr  on de.delivery_memo_id=pr.delivery_memo_id WHERE 
     de.delivery_memo_id=$delivery_memo_id");
    $this->load->view('delivery_memo/print_layout', array('data1' => $query->result()));
}

然后，您应该能够在视图中访问$data1变量，例如：

<?php foreach ($data1 as $row) { echo $row->product_id . "'n"; } ?>

显然，

您不了解如何访问传递给视图的数据。你正在将数组传递给你的视图，视图中不会有$data1变量，会有变量，它们在你传递的数组中被命名为键。所以你应该像这样传递数据：

$this->load->view('delivery_memo/print_layout',array('data1' => $data1));

之后，$data1将在视图中访问：

var_dump($data1);
