Codeigniter - 表单验证不起作用

Question

我已经尝试了谷歌搜索，但没有解决，我的代码下面是插入前检查重复，当“tagnumber”字段已存在将去特定的页面，并没有插入到表，它的工作原理，但问题是虽然没有插入表格，但它不会去我想要的特定页面。下面

是我的条件语句问题：
如果数据上表单验证存在将执行不插入数据。
如果数据不存在表单验证将执行插入数据，但转到错误的页面（与存在数据页面相同的页面）。

我controoler：

function tambahSubmit() 
{ 

$tagnumber = $this->input->post("tagnumber"); 
$this->myigniter_model->addData($tagnumber); 
$this->load->helper(array('form', 'url')); 
$this->load->library('form_validation'); 

// field name, error message, validation rules 
$this->form_validation->set_rules('tagnumber', 'tagnumber', 'trim|required|is_unique[inventorytag.tagnumber]'); 
$this->form_validation->set_rules('date', 'date', 'trim|required'); 
$this->form_validation->set_rules('employee', 'employee', 'trim|required'); 
$this->form_validation->set_rules('semnumber', 'semnumber', 'trim|required'); 
$this->form_validation->set_rules('quantity', 'quantity', 'required'); 
$this->form_validation->set_rules('area', 'area', 'trim|required'); 



if($this->form_validation->run() == false) 
{ 

    $this->load->view('YearEndStock/tampilan_input_gagal'); 
} 
else 
{ 

    $this->myigniter_model->addData($tagnumber); 

    $this->load->view('YearEndStock/tampilan_input_sukses'); 


} 
} 

我的模型：

function addData($tagnumber) 
{ 
    // Added $this->db->escape() and limit 1 for Performance 
$query = $this->db->query("SELECT tagnumber FROM inventorytag WHERE tagnumber = ".$this->db->escape($tagnumber)." limit 1"); 

$data = array(  
'tagnumber' => $this->input->post('tagnumber'), 
'date'=> date('Y-m-d H:i:s'), 
'employee' => $this->input->post('employee'), 
'semnumber' => $this->input->post('semnumber'), 
'quantity' => $this->input->post('quantity'), 
'area' => $this->input->post('area') 
); 

return $query->num_rows() == 0 ? $this->db->insert('inventorytag', $data) : false; 
} 

Answer 1

然后你只需要单独您真实的陈述。删除你的is_unique验证。

if($this->form_validation->run() == false) 
{ 
    SHOW ERRORS 
    $this->load->view('YearEndStock/tampilan_input_gagal'); 
} 
else 
{ 
    $row = $this->db->get_where('inventorytag', array('tagnumber' => $tagnumber))->row(); 

    if (empty($row)) { 
    //insert 
    $this->myigniter_model->addData($tagnumber); 
    } else { 
    //row exists 
    } 

    $this->load->view('YearEndStock/tampilan_input_sukses'); 


}
