Some error while submit form with empty field in PHP , Codeigniter

Question

I am using Codeigniter framework.

My issue is:-

when I submit my booking form its shows me 503 service unavailable page if form fields are empty.

If all form fields have value then form is success fully submitting.

please do a check by `if else` a form have filled by data or not. — KUMAR, Sep 11 '21 at 11:19
@KUMAR it worked when I removed If statement. But that If statement is for serverside validation. any other way to avoid this? — Yadhu Babu, Sep 11 '21 at 11:26
load $this->load->library('form_validation'); in your function??? — Ganpat Thakor, Sep 13 '21 at 10:42

You do this by varrious ways:-

(1) Form Validation

you need to set rules for input fields

$this->form_validation->set_rules('username', 'Username', 'required');
if ($this->form_validation->run() == FALSE)
  {
    //run your code on success here
  }
else
  {
    //run your code on failure here
  }

(2) By if else statement Condition.

 if ($_POST) {
        $data = array(
            'category' => $this->input->post('category'),
            'name' => $this->input->post('name'),
            'description' => $this->input->post('description'),
           );
        $this->model_name->method_name($data);
        redirect(base_url().'Controller/method/');
    } else {
     redirect(base_url().'Controller/method');
         }

i have done this server side validation. Not for all fields only for required fields. when I removed this if statement everything works fine — Yadhu Babu, Sep 11 '21 at 11:28
