codeigniter回显查询结果数组 [英] codeigniter echo query result array

问题描述

模型内的方法：

    public function get_fichas(){

    $query = $this->db->query("SELECT * FROM fichas;");

    return $query->result();

}

然后，我正在尝试将此数据传递给控制器。控制器上的方法：

Then, I'm trying to pass this data to the controller. Method on the controller:

public function listar_fichas(){

    $data['fichas_info'] = $this->fichas_model->get_fichas();
    $this->load->view('templates/header');
    $this->load->view('fichas/listar_fichas', $data);

}

当我尝试在视图中列出数据时，我出现以下错误：

When I try to list the data in a view, I get the following error:

致命错误：无法将stdClass类型的对象用作数组

"Fatal error: Cannot use object of type stdClass as array"

这是我尝试列出的方式：

Here is how I'm trying to list:

查看文件：

<?php foreach($fichas_info as $row){?>
    <table>
        <tr>
            <td><?php echo $row['cod_produto'] ;?></td>
            <td><?php echo $row['nome_produto'] ;?></td>
            <td ><?php echo $row['versao'];?></td>
        </tr>
    </table>
<?php }?>

我认为我在视图中做错了。也许我是错误地将数据传递给视图。有人可以告诉我我做错了吗？谢谢！

I think I'm doing something wrong on the view. Perhaps I'm passing the data incorrectly to the view. Can someone please tell what I'm doing wrong? Thank you!

推荐答案

<td><?php echo $row['cod_produto'] ;?></td>
<td><?php echo $row['nome_produto'] ;?></td>
<td><?php echo $row['versao'];?></td>

应为：

<td><?php echo $row->cod_produto ;?></td>
<td><?php echo $row->nome_produto ;?></td>
<td ><?php echo $row->versao;?></td>

结果集是一个对象，因此每个列名称都是该对象的一个​​属性。您正在将它们作为数组的索引进行访问。

The result set is an object, so each column name is a property of the object. You were accessing them as an index of an array.
