checkbox data not insert in mysql using codeigniter - mysql

Question

I try to insert my checkbox data in CodeIgniter. but data did not inserted in the database.
here is my view file:
<input type="checkbox" name="feature[]" value="WIFI" >
<input type="checkbox" name="feature[]" value="TV">
I am trying to use implode to convert the array into the string, but then I don't how to add in $data array, so they inserted in together
here is my controller:
public function save()
{
$this->load->model('Partner_model');
$feature = $this->input->post('feature');
$fea=array(
'feature'=>json_encode(implode(",",$feature))
);
$user_data= array(
'pname' => $this->input->post('pname'),
'type' => $this->input->post('type'),
'address' => $this->input->post('address'),
'about' => $this->input->post('about'),
'city' => $this->input->post('city'),
'code' => $this->input->post('code')
);
if($this->Partner_model->save($user_data,$fea))
{
$msg = "save sucesss" ;
}
else
{
$msg = "not save";
}
$this->session->set_flashdata('msg', $msg);
$this->load->view('partner_profile');
}
& here is my model:
public function save($data,$fea)
{
return $this->db->insert('property', $data,$fea);
}

Answer 1

Your model is faulty.
You are passing three arguments to insert() but the third you use is not appropriate.
That argument should be a boolean that indicates whether to escape values and identifiers or not. You need to incorporate $fea into $data which should probably be done in the controller.
There is an easier way to create the array $user_data since it is essentially a copy of $_POST just use $this->input->post().
Also, there is no obvious reason why you use json_encode. Unless you need it that way when you retrieve it from the DB there is no reason to bother with it. Consider removing json_encode.
First, change the model
public function save($data)
{
return $this->db->insert('property', $data);
}
Here's a revised save method
public function save()
{
$this->load->model('Partner_model');
$user_data = $this->input->post(); //makes a copy of $_POST
$feature = $this->input->post('feature');
if($feature) //because $feature will be null if no boxes are checked
{
$user_data['feature'] = json_encode(implode(",", $feature));
}
$msg = $this->Partner_model->save($user_data) ? "save sucesss" : "not save";
$this->session->set_flashdata('msg', $msg);
$this->load->view('partner_profile');
}
An explanation as requested via comments.
A call to $this->input->post('pname') returns the value of $_POST['pname'] if it is exists, but returns null if it does not exist.
When you create $user_data you make six calls to $this->input() with a different "key" each time to make a copy of $_POST.
$this->input->post() without any arguments returns the whole $_POST array. (See documentation)
$user_data = $this->input->post();
Makes a copy of $_POST using one line of code. It will include $_POST['feature'] if any boxes are checked, but $_POST['feature'] will not be set if no boxes are checked.
There are two ways to test if any boxes were checked. First we can test if isset($_POST['feature']) == true or we can test if $this->input->post('feature') == true. I use the second with the call
if($feature)
Which is pretty much the same as any of the following lines
if($feature != false)...
if($feature != null)...
if( ! empty($feature))...
if( ! is_null($feature))...
In other words, if($feature) evaluates as true if $feature is set and is anything except null, false, 0, "0", "" (an empty string), array() (an empty array)

public function save()
{
$this->load->model('Partner_model');
$feature = $this->input->post('feature');
$user_data= array(
'pname' => $this->input->post('pname'),
'type' => $this->input->post('type'),
'address' => $this->input->post('address'),
'about' => $this->input->post('about'),
'city' => $this->input->post('city'),
'code' => $this->input->post('code'),
'feature'=>json_encode(implode(",",$feature))
);
if($this->Partner_model->save($user_data)){
$msg = "save sucesss" ;
}else{
$msg = "not save";
}
$this->session->set_flashdata('msg', $msg);
$this->load->view('partner_profile');
}
model file should be :
public function save($data) {
return $this->db->insert('property', $data);
}
