我有一个函数如下：
function get_employee_information()
{
$this->db
->select('id, name');
$query = $this->db->get('sales_people');
$employee_names = array();
$employee_ids = array();
foreach ($query->result() as $row) {
$employee_names[$row->id] = $row->name;
$employee_ids[] = $row->id;
}
}
我正试图从输出到模板中访问这些数据，如下所示：
$this->get_employee_information();
$output = $this->template->write_view('main', 'records', array(
'employee_names' => $employee_names,
'employee_ids' => $employee_ids,
), false);
然而，这并没有显示出什么。我觉得这是一件小事，我应该更清楚。当我在函数内的任意一个数组上tunprint_r（$arrayname）时，我会得到可疑的数组值。当我在函数的外部打印_r时，它什么也不返回。
您的函数没有返回任何内容。添加如下所示的退货。
function get_employee_information()
{
$this->db->select('id, name');
$query = $this->db->get('sales_people');
$employee_names = array();
$employee_ids = array();
foreach ($query->result() as $row) {
$employee_names[$row->id] = $row->name;
$employee_ids[] = $row->id;
}
return array(
'employee_names'=>$employee_names,
'employee_ids'=>$employee_ids,
);
}
您没有将函数的return值设置为变量
$employee_info = $this->get_employee_information();
$output =
$this->template->write_view(
'main', 'records',
array(
'employee_names' => $employee_info['employee_names'],
'employee_ids' => $employee_info['employee_ids'],
),
false
);
