Codeigniter Model Undefined Index on Array

Question

I'm trying to use Codeigniter to update my value once the user had submitted the form. But unfortunately, there was an error of undefined index for few of the variable which I store in an array.

Below is the Code that I use to pass from Controller to the Model

Controller Code :

$prep_data = array(
                'full_name' => $this->input->post('full_name'),
                'nric' => $this->input->post('nric'),
                'dob' => $this->input->post('dob'),
                'mobile_phone' => $this->input->post('mobile_phone'),
                'email' => $this->input->post('email'),
                'address_line_1' => $this->input->post('address_line_1'),
                'address_line_2' => $this->input->post('address_line_2'),
                'postcode' => $this->input->post('postcode'),
                'state' => $this->input->post('state'),
                'current_brand' => $this->input->post('current_brand'),
                'pregnant' => $isPregnant, //Edit by Marcus
                'breastfeeding' => $isBreastfeeding, //Added by Marcus
                'child_full_name' => $this->input->post('child_full_name'),
                'child_dob' => $this->input->post('child_dob'),
                'child_current_brand' => $this->input->post('child_current_brand'),
                'expected_give_birth_date' => $this->input->post('expected_give_birth_date'),
                'image' => '',
                'quantity_purchase' => $this->input->post('quantity_purchase'),
                'foc_amount' => $this->input->post('foc_amount'),
                'marketing_opt' => $this->input->post('marketing_opt'),
                'centre_id' => get_cookie('abbott_centre', TRUE),
                'user_id' => $this->session->id,
                'sampling_day' => $centre_data['sampling_day'],
                'created_at' => $datetime,
                'updated_at' => $datetime
            );
$this->entry_model->update_entry($prep_data);

Model Code :

   function update_entry($data){
        echo print_r($data);
        if(!empty($data['full_name'])) $this->db->set('full_name', $data['full_name']);
        if(!empty($data['nric'])) $this->db->set('nric', $data['nric']);
        if(!empty($data['dob'])) $this->db->set('dob', $data['dob']);
        if(!empty($data['mobile_phone'])) $this->db->set('mobile_phone', $data['mobile_phone']);
        if(!empty($data['email'])) $this->db->set('email', $data['email']);
        if(!empty($data['address_line_1'])) $this->db->set('address_line_1', $data['address_line_1']);
        if(!empty($data['address_line_2'])) $this->db->set('address_line_2', $data['address_line_2']);
        if(!empty($data['postcode'])) $this->db->set('postcode', $data['postcode']);
        if(!empty($data['state'])) $this->db->set('state', $data['state']);
        if(!empty($data['current_brand'])) $this->db->set('current_brand', $data['current_brand']);
        if(!empty($data['pregnant'])){ //Fix by Marcus
            $this->db->set('pregnant', $data['pregnant']);
        }else {
            $this->db->set('pregnant', 0);
        }
        if(!empty($data['breastfeeding'])){ //Fix by Marcus
            $this->db->set('breastfeeding', $data['breastfeeding']);
        }
        else {
            $this->db->set('breastfeeding', 0);
        }
        if(!empty($data['expected_give_birth_date'])) $this->db->set('expected_give_birth_date', $data['expected_give_birth_date']);//Fix by Marcus
        if(!empty($data['child_full_name'])) $this->db->set('child_full_name', $data['child_full_name']);
        if(!empty($data['child_dob'])) $this->db->set('child_dob', $data['child_dob']);
        if(!empty($data['child_current_brand'])) $this->db->set('child_current_brand', $data['child_current_brand']);
        if(!empty($data['image'])) $this->db->set('image', $data['image']);
        if(isset($data['quantity_purchase'])) $this->db->set('quantity_purchase', $data['quantity_purchase']);
        if(isset($data['foc_amount'])) $this->db->set('foc_amount', $data['foc_amount']);
        if(!empty($data['marketing_opt'])) $this->db->set('marketing_opt', $data['marketing_opt']);
        if(!empty($data['centre_id'])) $this->db->set('centre_id', $data['centre_id']);
        if(!empty($data['user_id'])) $this->db->set('user_id', $data['user_id']);
        if(!empty($data['created_at'])) $this->db->set('created_at', $data['created_at']);
        if(!empty($data['updated_at'])) $this->db->set('updated_at', $data['updated_at']);

        $this->db->where('id', $data['id']);
        $this->db->update('entry');
    }

Other $data[] value had no problem but only the 'pregnant' and 'breastfeeding' had the error on Undefined Index. I did try to print_r to show the $data value and all are seem to be alright.

Below are the output :

Array ( [full_name] => e2e [nric] => 123 [dob] => 2019-07-09 [mobile_phone] => 1231231231 [email] => [address_line_1] => [address_line_2] => [postcode] => [state] => [current_brand] => [pregnant] => 0 [breastfeeding] => 1 [child_full_name] => [child_dob] => 0000-00-00 [child_current_brand] => [expected_give_birth_date] => 2019-07-09 [image] => [quantity_purchase] => 123123 [foc_amount] => 123 [sampling_day] => [updated_at] => 2019-07-10 19:27:43 [id] => 8 ) 1Array ( [image] => 8_20190710_192743.jpg [id] => 8 ) 1

What will be the caused for this 'pregnant' and 'breastfeeding' array? As it keeps getting NULL as a return.

Thanks

try this in controller 'breastfeeding' => $isBreastfeeding ? $isBreastfeeding : '', and 'pregnant' => $isPregnant ? $isPregnant, : '', — Ivan

$isPregnant and $isBreastfeeding where you defined these two variables? error is not related to your model, as its already defined — devpro

@bobibobi sorry your method not working Message: syntax error, unexpected ',' — Marcus Tan

@devpro Here $isPregnant = 0; $isBreastfeeding = 0; if($this->input->post('pregnant') == 1){ $isBreastfeeding = 0; $isPregnant = 1; //Is breastfeeding selected } if($this->input->post('breastfeeding') == 1){ $isPregnant = 0; $isBreastfeeding = 1; //Is breastfeeding selected } — Marcus Tan

You need to use isset() to check either index set or not like

$isPregnant = 0; 
$isBreastfeeding = 0; 
if(isset($_POST['pregnant']) && $_POST['pregnant'] == 1)
{ 
    $isBreastfeeding = 0; 
    $isPregnant = 1; //Is breastfeeding selected    
} 

if(isset($_POST['breastfeeding']) && $_POST['breastfeeding'] == 1)
{ 
    $isPregnant = 0; 
    $isBreastfeeding = 1; //Is breastfeeding selected 
}

Fatal error: Cannot use isset() on the result of an expression (you can use "null !== expression" instead)

@MarcusTan: then you can use $_POST
