Try this below coding .... 试试下面的编码....
if ($this->form_validation->run() == TRUE) {
extract($_POST);
foreach($surname as $key=>$value) {
$reg_dat = array(
'surname' => $value,
'name' => $firstname[$key],
'age' => $age[$key],
'school' => $school[$key],
'course' => $course[$key],
'email' => $email[$key],
);
$this->user_model->add_user($reg_dat);
}
}
$this->load->view('user/home_view');

Seems that your Post can be a multidimensional array. 似乎您的帖子可以是多维数组。 I think the best way to solve your problem is to foreach that post and insert every row 我认为解决问题的最佳方法是遍历每个帖子并插入每一行
//your controller
if ($this->form_validation->run() == TRUE) {
$reg_dat_multi = $this->input->post();
foreach ($reg_dat_multi as $reg_dat) {
$this->user_model->add_user($reg_dat);
}
);
you didn't show your model but let's think that is something like this 您没有显示您的模型，但让我们想像这样
//your model
function add_user($reg_dat){
if ( $this->db->insert('table', $reg_dat) ){
return true;
}
return false;
}
hope that helps 希望能有所帮助
