我有几个 $ data ,几乎在控制器的所有功能中都会调用它们。有没有办法在 __ construct 函数中创建 $ data ,并将它们与被调用函数中的 $ data 组合?例如:
function __construct() {
parent::__construct();
$this->load->model('ad_model', 'mgl');
$this->load->model('global_info_model', 'gi');
$this->load->model('user_model', 'um');
$this->load->library('global_functions');
$this->css = "<link rel=\"stylesheet\" href=\" " . CSS . "mali_oglasi.css\">";
$this->gi_cat = $this->gi->gi_get_category();
$this->gi_loc = $this->gi->gi_get_location();
$this->gi_type = $this->gi->gi_get_type();
}
function index() {
$count = $this->db->count_all('ad');
$data['pagination_links'] = $this->global_functions->global_pagination('mali_oglasi', $count, 2);
$data['title'] = "Mali Oglasi | 010";
$data['oglasi'] = $this->mgl->mgl_get_all_home(10);
$data['loc'] = $this->gi_loc;
$data['cat'] = $this->gi_cat;
$data['stylesheet'] = $this->css;
$data['main_content'] = 'mali_oglasi';
$this->load->view('template',$data);
}
如果我想要 $ data ['loc'] , $ data ['cat'] 和 $ data ['stylesheet'] __ construct 我必须在 $ this-&gt; loading-&gt;视图中调用 $ this-&gt;数据('template',$ data );
有没有办法将这两者结合起来?

将一个私有成员添加到您的控制器并根据需要在构造函数中设置它:
private $data;
function __construct() {
...
$this->data = array(...);
...
}
然后,您可以在同一控制器类中的所有控制器操作中访问此私有成员。
您可以使用array union operator (+
)Docs合并两个数组:
$data = $this->data + $data;
请参阅:PropertiesDocs

当然,你可以这样做,
class ControllerName extends CI_Controller {
private $_data = array();
function __construct()
{
$this->_data['loc'] = this->gi_loc;
$this->_data['cat'] = this->gi_cat;
$this->_data['stylesheet'] = this->css;
}
function index()
{
// Your data
// Merge them before the $this->load->view();
$data = array_merge($this->_data, $data);
}
}
