這是我的功能function store(){ $this->load->library('form_validation'); $this->form_validation->set_rules('shorthand','Shorthand','required|is_unique[locations.shorthand]'); if($this->form_validation->run() == FALSE){ redirect('locations'); } else { $id = $this->input->post('location_id'); $location_name = ucwords(strtolower($this->input->post('location_name'))); $shorthand = strtolower($this->input->post('shorthand')); $station = ucwords(strtolower($this->input->post('station'))); $data = array( 'location_name'=>$location_name, 'shorthand'=>$shorthand, 'station'=>$station ); }if($id){ $result = $this->location_model->update($data,$id); if($result > 0){ $this->session->set_flashdata('success', 'Update successfull!'); }else{ $this->session->set_flashdata('error', 'Failed to update!'); } redirect('locations'); }else{ $result = $this->location_model->create($data); if($result > 0){ $this->session->set_flashdata('success', 'Location added!'); }else{ $this->session->set_flashdata('error', 'Failed to add location!'); } redirect('locations'); } }速記更新很好，但無論我做什么，station 和 location_name 都不會更新。但是如果我刪除這段代碼。$this->load->library('form_validation'); $this->form_validation->set_rules('shorthand','Shorthand','required|is_unique[locations.shorthand]'); if($this->form_validation->run() == FALSE){ redirect('locations'); } else {所有字段都將更新。你能看看我的代碼嗎？提前致謝。

我認為這是你需要的。請根據您的需要進行管理
$locations = $this->db->get_where('locations', array('location_id' => $id))->row();
$original_value = $locations->shorthand;
if($this->input->post('shorthand') != $original_value) {
$is_unique = '|is_unique[locations.shorthand]';
} else {
$is_unique = '';
}
$this->form_validation->set_rules('shorthand','Shorthand','required|trim|xss_clean'.$is_unique);

那些評論過的人，謝謝，但我已經解決了控制器內部的問題，我忘了在這行后面加上其他內容
if($this->form_validation->run() == FALSE){
redirect('locations');
}
這就是整個函數現在的樣子
function store(){
$this->form_validation->set_rules('location_name','Location_name','required');
$this->form_validation->set_rules('shorthand','Shorthand','required|callback_locationExists');
$this->form_validation->set_rules('station','Station','required');
$id = $this->input->post('location_id');
$location_name = ucwords(strtolower($this->input->post('location_name')));
$shorthand = strtolower($this->input->post('shorthand'));
$station = ucwords(strtolower($this->input->post('station')));
$data = array(
'location_name'=>$location_name,
'shorthand'=>$shorthand,
'station'=>$station,
);
if($this->form_validation->run() == FALSE){
redirect('locations');
}else{
if($id){
$result = $this->location_model->update($data,$id);
if($result > 0){
$this->session->set_flashdata('success', 'Update successfull!');
}else{
$this->session->set_flashdata('error', 'Failed to update!');
}
redirect('locations');
}else{
$result = $this->location_model->create($data);
if($result > 0){
$this->session->set_flashdata('success', 'Location added!');
}else{
$this->session->set_flashdata('error', 'Failed to add location!');
}
redirect('locations');
}
}
}
謝謝閱讀
