型号:
func == (lhs: Employee, rhs: Employee) -> Int {
return (lhs.empName == rhs.empName && lhs.empCode == rhs.empCode)?1:0
}
控制器:
function search()
{
$cari=$this->db->query("select * from uhd_user_order where user_order_reference ");
return $cari->result();;
}
查看:
function search_keyword()
{
$this->input->GET('cari', TRUE);
$beda['cari'] = $this->order_test_m->search();
$this->load->view('admin/a',$beda);
}
我需要进行搜索,如果我只输入正确的代码,则会显示视图的结果。就像,如果我只搜索“s”,我的数据库中的数据将不会显示。
如何做到这一点?

我不确定你想要什么,我对你的代码有一些疑问,但我还不能发表评论。我必须猜测发生了什么:
我认为您的代码的工作原理是:每当“搜索”'单击按钮,将显示数据库中的所有用户名,对吧?
因为您的模型没有使用' get'要在数据库中搜索的数据
//Your function does not recieve the search string.
//This function uses $string to search in the 'users' table, to finds the name field == $string, and returns only 'name' row.
function search($string){
$query = $this->db->select('name')
->where('name',$string)
->get('users');
//If the result is empty, return false, do nothing.
if($query->num_rows() === 0){
return false;
}
return $query->result();;
}
控制器
function search_keyword()
{
// Call search function with the input data.
// I think here will have some validation
//for example:
//if($this->form_validation->run() == false){
// $this->load->view('errors/error');
//}
$search_string = $this->input->GET('cari', TRUE);
$beda['cari'] = $this->order_test_m->search($search_string);
$this->load->view('admin/a',$beda);
}
查看:
// This will ensure the ul will only display when $cari is not empty.
<?php if(count($cari)>0):?>
<ul>
<?php foreach($cari as $row):?>
<li><?php echo $row->name;?></li>
<?php endforeach;?>
</ul>
<?php endif; ?>>
