Codeigniter Forms Post Data is empty

Question

I have been trying to set up an existing CI 3.1 project locally in xampp. The database is connected and the website loads but the login/register/forms are not working.

Upon checking in detail found the forms are not sending in the post data. Post object is empty.

Below is the code.

Login View

<!-- language-all: lang-php-->
<form id="app-form" class="card auth_form" method="post" action="<?php echo site_url('auth/login/') ?>">
 <div class="header">

 }
 } else {

 return false;
 }
}

• dnapierata: It appears that your Sign up function is an anchor tag so it will only navigate when clicked (without submitting the form data). The SIGN IN button should be sending data. Perhaps try putting var_dump($_POST); die(); at the top of Auth controller to verify that you are receiving the form data?
• infamous_bad_habits: @dnapierata I have tried debugging and the post returns empty.

Answer 1

try grab the input first than pass it to model... in your controller Auth/login put this code

$email = $this->security->xss_clean($this->input->post('email')); $password = $this->security->xss_clean($this->input->post('password'));

and than pass it to your model auth/validate by calling

$result = $this->AuthModel->validate($email, $password);

the code should be like this...

AUTH CONTROLLER

public function login()
{ 
 $email = $this->security->xss_clean($this->input->post('email'));
 $password = $this->security->xss_clean($this->input->post('password'));
 $response = array('type'=>'', 'page'=>'', 'message'=>'');
 // Load the model
 $this->load->model('AuthModel');
 // Validate the user can login
 $result = $this->AuthModel->validate($email, $password);
 var_dump($_POST);
 // Now we verify the result
 if(!$result){
 $response['type'] = 'error';
 $response['message'] = 'Invalid username and/or password.';
 }else{
 $response['type'] = 'redirect';
 $response['page'] = site_url().'RecordVerify/lists';
 $response['message'] = 'Login successful';
 }
 echo json_encode($response);
}

AUTH MODEL

public function validate($email, $password)
{
 // Prep the query
 $this->db->select("users.*,user_roles.role_name");
 $this->db->from('users');
 $this->db->join('user_roles', 'users.role = user_roles.URID');
 $this->db->where('users.email', $email);
 //$this->db->where('users.user_password', password_verify($password,'user_password'));
 $this->db->where('users.status', 1);
 $query = $this->db->get();
 // Let's check if there are any results
 if ($query->num_rows() != 0) {
 // If there is a user, then create session data
 $row = $query->row();
 $thehashvalue= hash('sha256', $row->salt . hash('sha256', $password) );
 if($row->password == $thehashvalue)
 {
 $data = array(
 'user_id' => $row->id,
 'first_name' => $row->first_name,
 'last_name' => $row->last_name,
 'full_name' => $row->first_name.' '.$row->last_name,
 'email' => $row->email,
 'user_role_id' => $row->role,
 'user_role_name' => $row->role_name,
 'user_report' => $row->report,
 'validated' => true
 );
 $this->session->set_userdata($data);
 return true;
 }else{
 return false;
 }
 } else {
 // If the previous process did not validate
 // then return false.
 return false;
 }
}
