如何最小化此PHP代码

Question

任何人都可以提供帮助。 我想尽量减少脏代码，逻辑薄弱。 先感谢您..

//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，您可以执行以下操作：

//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');

添加要添加的尽可能多的规则，然后只想确认其是否已验证，请使用以下命令：

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