Question

I am inserting data to database using codeigniter. But it keeps giving me below error

Unknown column 'Array' in 'field list'</p><p>INSERT INTO `profile` (`loginid`, `name`, `email`, `gender`, `birthday`, `profilePhoto`, `date`) VALUES (Array, 'Zafar Khan', '[e-mail]', 'male', '20.01.1987', '', '2012/11/19')

Filename: /Applications/XAMPP/xamppfiles/htdocs/membership_system/models/model_register.php</p><p>Line Number: 48

Here is the code where this error occurs

public function saveUserProfile() {
    $userId = $this->readUserId();

    $profile = array(
            'loginid'       => $userId,
            'name'          => $this->input->post('name'),
            'email'         => $this->input->post('email'),
            'gender'        => $this->input->post('gender'),
            'birthday'      => $this->input->post('birthday'),
            'profilePhoto'  => '',
            'date'          => date("Y/m/d")
        );

    $query = $this->db->insert('profile', $profile);

    if ($query) {
        return true;
    } else {
        return false;
    }
}

UPDATE

here is readUserId function

private function readUserId() {
    $this->db->select('id'); 
    $this->db->from('login');   
    $this->db->where('email', $this->input->post('email'));

    return $this->db->get()->result();
}

UPDATE 2

Here is my output for var_dump

array(1) {  [0]=>  object(stdClass)#18 (1) {    ["id"]=>    string(2) "14"  } }

Answer 1

Seems that $this->readUserId() returns an Array.
Can you try reset($this->readUserId()); ?
Put it before initializing $profile.

Or just

echo var_dump( $this->readUserId() );

die();

..So that we can see what’s inside your variable.

==> EDIT:

$profile must become something like

$profile = array(
            'loginid'       => $userId['id'],
            'name'          => $this->input->post('name'),
            'email'         => $this->input->post('email'),
            'gender'        => $this->input->post('gender'),
            'birthday'      => $this->input->post('birthday'),
            'profilePhoto'  => '',
            'date'          => date("Y/m/d")
        );

==> EDIT 2:

Okay, then you can add

$userId = $userId[0]->id;

Before the $profile variable initialization.
