如何最小化此PHP代碼

Question

任何人都可以提供幫助。我想盡量減少我的髒代碼，我在邏輯上很弱。預先感謝您..

//These are all fields 
$prodname = $this->input->post('prodname'); 
$price = $this->input->post('price'); 
$qty = $this->input->post('qty'); 
$desc = $this->input->post('desc'); 
$status= $this->input->post('status'); 


// This part I want to minimize, or any shorthand for this code?? 
if ($prodname != NULL && $price != NULL && $qty != NULL && $desc != NULL && $status != NULL) 
    $datas = $this->controller->add_product($data); 

Answer 1

是的，你可以做到以下幾點：

//These are the fields coming from form "username" is the name of field 

$this->form_validation->set_rules('username', 'Username', 'required'); 
$this->form_validation->set_rules('password', 'Password', 'required'); 
$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required'); 

添加要添加儘可能多的規則，那麼你只是想確認它是否有效或不使用此：

if ($this->form_validation->run() == FALSE) 
{ 
    $this->load->view('myform'); 
} 
else 
{ 
    $this->load->view('formsuccess'); 
}
