CI Mapping (loading) data to the view layer method _php instance

The examples in this paper describe the method of CI mapping (loading) data to the view layer. Share to everyone for your reference, as follows:

CI has a disgusting thing, it is necessary to put all the data into the $data array in order to map to the view layer, such as:

Currently I search out the data mode from the link table of the Database (Link table, field: id name URL):

$query = $this->db->query ("Select Id,name,url from Cg_link where 1"); $links = $query->result ();//Here's $ Links cannot be transferred directly into the view layer. Error//Wrong transmission (mapping mode)://$this->load->view (' link ', $links);//correct transmission (map mode): $data [' links '] = $ Links; $this->load->view (' link ', $data);

So as long as the data transfer must be put into the $data, if you want to query a data or a one-dimensional array, use the following function

$sql = "Select Id,name,url from Cg_link where id=21 limit 1"; $query = $this->db->query ($sql); $one = $query->row () ;//Here is a piece of data, get the way, $one->name;

It is hoped that this article is helpful to the PHP program design based on CodeIgniter framework.
