codeigniter ignores empty post data..issue with validation

how can i show the empty field that user submit??

if($this->input->post('name')){
    $data['name'] = $this->input->post('name');
}elseif(!empty($details)) {
    $data['name'] = $details['name'];
}else{
    $data['name'] = '';
}

But if user clear the input field and submit, it wont show the input as empty it will execute the elseif statement though user submit post request.

How to avoid this?

i want to say the field is empty

$this->input->post returns false only when name is absent in POST array

$data['name'] = $this->input->post('name');
// here empty($data['name']) gives you correct answer
if (!$data['name'])
   $data['name'] = empty($details) ? '' : $details['name'];

This validation checks whether the field in the $_POST exists or not.

If you want to restrict the user to avoid empty entries. There 2 approaches for that:

1) Client side (use jquery or javascript or just use html5's tag required='required' in <input tag that would work)

2) Server side, 

if($this->input->post('name')){
   $setErrorMessage = "Empty field is not allowed";  
}

and return the user to the page along with the error message(s).
