uploading image and data in mysql table in codeigniter - php

Question

I'm trying to upload an image with a car make, year, lease and payment data
along with the image upload. My image path is also inserted to the DB but i still cant figure how to combine both.
Im getting an error Array to string conversion and its not inputting my data and image upload.
cars table:
car_make | car_model | car_year | car_lease | car_payment | imgpath
acura | G37 Sedan | 2009 | 48 | 350 | assets/images/acura_1.jpg
controller:
public function car_validation_do_upload() {
$this->load->library('form_validation');
$this->form_validation->set_rules('car_make', 'Car Make', 'required');
$this->form_validation->set_rules('car_model', 'Car Model', 'required');
$this->form_validation->set_rules('car_year', 'Car Year', 'required');
$this->form_validation->set_rules('car_lease', 'Car Lease', 'required');
$this->form_validation->set_rules('car_payment', 'Car Payment', 'required');
if($this->form_validation->run() == TRUE) {
$config['upload_path'] = './assets/images/';
$config['allowed_types'] = 'gif|jpeg|jpg|png';
$this->load->library('upload', $config);
$newRow = array("car_make" => $this->input->post('car_make'),
"car_model" => $this->input->post('car_model'),
"car_year" => $this->input->post('car_year'),
"car_lease" => $this->input->post('car_lease'),
"car_payment" => $this->input->post('car_payment'));
$data = array('upload' => $this->upload->data());
$result = array_merge($newRow, $data);
$this->load->model("model_users");
$this->model_users->insert1($result);
$this->session->set_flashdata('message', 'car inserted into database!');
redirect('main/insertCar');
}
else {
$this->load->view('insert_car');
}
}
Model:
public function insert1($data) {
$this->db->insert("cars", $data);
}

Change this:
$data = array('upload' => $this->upload->data());
$result = array_merge($newRow, $data);
To this:
if ($this->upload->do_upload()){
$image_data = $this->upload->data();
//this will create a new key with the name upload in your newRow
//so theres no need to use the function array_merge
$newRow['imgpath'] ='assets/images/'.$image_data['file_name'];
}
else{
//do something here
echo 'error uploading image'
}
The $image_data variable will have this information about your uploaded image
Array
(
[file_name] => mypic.jpg
[file_type] => image/jpeg
[file_path] => /path/to/your/upload/
[full_path] => /path/to/your/upload/jpg.jpg
[raw_name] => mypic
[orig_name] => mypic.jpg
[client_name] => mypic.jpg
[file_ext] => .jpg
[file_size] => 22.2
[is_image] => 1
[image_width] => 800
[image_height] => 600
[image_type] => jpeg
[image_size_str] => width="800" height="200"
)
