如何最小化此PHP代码(How minimize this PHP CODE)

有人可以帮忙。我想最小化我的脏代码，我的逻辑很弱。先谢谢你..

//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);

Anyone can help. I want to minimize my dirty code, I'm weak in logic. Thank you in advance..

//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);

最满意答案

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');

添加要添加的规则，然后您只想确认它是否已经过验证，请使用以下命令：

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

Yes you can do the following:

//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');

Add as many rules you want to add and then you just want to confirm if it's validated or not, use this:

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