所以,我使用 codeigniter 已经有一段时间了,我从来没有遇到过在我的模型中运行查询并将其返回到我的控制器的问题,控制器然后将它传递到我的视图中,在那里我将它作为对象访问,如下所示:
型号(某些型号)
function getdata()
{
$query = $this->db->get('sometable');
return $query;
}
控制器(一些控制器)
function controldata()
{
$this->load->model('somemodel');
$data['dbdata'] = $this->somemodel->getdata();
$this->load->view('someview',$data);
}
查看(某些视图)
<?php
foreach($dbdata->result() as $row) {
echo $row->id;
echo $row->name;
echo $row->whatever;
echo "<br />";
}
?>
但现在无论出于何种原因,在 2.0 中,它都将 $dbdata->result_array() 用作 $row 。
基本上它将结果作为数组返回。
没有任何意义,新版本有什么变化吗?
谢谢,
所以这是我的代码:
模型(管理员模型)
function show_allproducts($sort,$order,$limit,$offset)
{
$this->db->select('products.id,productcategories.categoryname,products.name,products.internetspecial,products.added,products.modified');
$this->db->from('products');
$this->db->join('productcategories','products.productcategories_id = productcategories.id');
$this->db->order_by($sort,$order);
$this->db->limit($limit,$offset);
$query = $this->db->get();
if($query->num_rows() > 0)
{
return $query;
}
else
{
return FALSE;
}
}
控制器(管理员)
function show_allproducts()
{
$data['title'] = 'All Products';
$this->load->library('pagination');
$config['base_url'] = 'http://'.$_SERVER['SERVER_NAME'].'/admin/show_allproducts';
$config['total_rows'] = $this->db->get('products')->num_rows();
$config['per_page'] = 10;
$config['num_links'] = 5;
$config['full_tag_open'] = '<div class="paggination right">';
$config['full_tag_close'] = '</div>';
$config['prev_link'] = '< prev';
$config['next_link'] = 'next >';
$config['cur_tag_open'] = '<a class="active">';
$config['cur_tag_close'] = '</a>';
$this->pagination->initialize($config);
$this->load->model('admin_model');
$data['tabledata'] = $this->admin_model->show_allproducts('name','ASC',$config['per_page'],$this->uri->segment(3));
$data['nav'] = 'admin/pagesections/nav';
$data['maincontent'] = 'admin/pages/show_allproducts';
$this->load->view('admin/template',$data);
}
查看(show_all_products)
<table border="0" cellpadding="0" cellspacing="0" width="100%">
<?php if($tabledata) { ?>
<tr>
<th>ID</th>
<th>CATEGORY</th>
<th>NAME</th>
<th>ADDED</th>
</tr>
<?php foreach($tabledata->result() as $row) { ?>
<tr>
<td><?php echo $row->id; ?></td>
<td><?php echo $row->categoryname; ?></td>
<td><?php echo $row->name; ?></td>
<td><?php echo $row->added;) ?></td>
</tr>
<?php } ?>
<?php } else { ?>
<tr>
<td>NO DATA</td>
</tr>
<?php } ?>
