Pass the value from a Controller to the view - php

Question

I created a form and passed the values for name and picture from the form. The value is accessed from the Upload controller as follows:
$data = array(
'title' => $this->input->post('title', true),
'name' => $this->input->post('name',true),
'picture' => $this->file_upload($_FILES['picture'])
);
return $data;
I need to pass these values to the view so, I modified the above code as:
class Upload extends CI_Controller
{
function __construct() {
parent::__construct();
}
public function input_values(){
$data = array(
'name' => $this->input->post('name',true),
'picture' => $this->file_upload($_FILES['picture'])
);
$this->load->view('documents', $data); }
function add(){
$data = $this->input_values();
if($this->input->post('userSubmit')) {
$this->file_upload(($_FILES['picture']));
if (!empty($_FILES['picture']['name'])) {
$config['upload_path'] = 'uploads/docs/';
$config['allowed_types'] = 'jpg|jpeg|png|gif|pdf|docx';
$config['file_name'] = $_FILES['picture']['name'];
$data['picture']=$this->file_upload($_FILES['picture']);
}
}
return $this->db->insert('files', $data);
}
//logo image upload
public function file_upload($file)
{
$this->my_upload->upload($file);
if ($this->my_upload->uploaded == true) {
$this->my_upload->file_new_name_body = 'file_' . uniqid();
$this->my_upload->process('./uploads/docs/');
$image_path = "uploads/docs/" . $this->my_upload->file_dst_name;
return $image_path;
} else {
return null;
}
}
}
But I am able to get only the value of title. Following error occurs for both name and title:
Message: Undefined variable: name
I have accessed the variables from the view as follows:
<?php var_dump($title)?>
<?php var_dump($name)?
<?php var_dump($picture)?>

so, this part is where you get the post data and load view (contain the upload form)
public function input_values() {
$data = array(
'name' => $this->input->post('name',true),
'picture' => $this->file_upload($_FILES['picture'])
);
$this->load->view('documents', $data);
}
then this part is handle the post request from the upload form:
function add() {
$data = $this->input_values();
if($this->input->post('userSubmit')) {
$this->file_upload(($_FILES['picture']));
if (!empty($_FILES['picture']['name'])) {
$config['upload_path'] = 'uploads/docs/';
$config['allowed_types'] = 'jpg|jpeg|png|gif|pdf|docx';
$config['file_name'] = $_FILES['picture']['name'];
$data['picture']=$this->file_upload($_FILES['picture']);
}
}
return $this->db->insert('files', $data);
}
and this part is where you upload the file
public function file_upload($file)
{
$this->my_upload->upload($file);
if ($this->my_upload->uploaded == true) {
$this->my_upload->file_new_name_body = 'file_' . uniqid();
$this->my_upload->process('./uploads/docs/');
$image_path = "uploads/docs/" . $this->my_upload->file_dst_name;
return $image_path;
} else {
return null;
}
}
when you call add() function, it call input_values() function then load views then the next line of codes won't be executed (cmiiw).
so, maybe you want to change with this :
public function index() {
if ($this->input->post()) {
// then handle the post data and files tobe upload here
// save the post data to $data, so you will able to display them in view
} else {
// set the default data for the form
// or just an empty array()
$data = array();
}
// if the request was not a post, render view that contain form to upload file
$this->load->view('nameOfTheView', $data);
}
