Codeigniter image upload validation with controller and function - php

Question

I have a small issue on this code for the to add a product on my system I am using V_add_pro function, when the image upload part is coming I am facing some issues to validate, so that I used a different function to validate through callback, its not working. the main issue is i am saving the image name only to the database, so how to return the image name only?
public function v_add_pro(){
$this->load->model('B_menu');
$data = array('status' => false, 'msg' => array());
$this->load->library('form_validation');
$this->form_validation->set_rules("pro_name", "name needed", "trim|required");
$this->form_validation->set_rules("pro_price", "price needed", "trim|required");
$this->form_validation->set_rules("pro_desc", "description is needed", "trim|required");
$this->form_validation->set_rules("dropzone", "select an image", "trim|required|callback_validate_image");
$this->form_validation->set_rules("pro_cat", "please select a category","callback_check_default|trim|required");
$this->form_validation->set_error_delimiters('<p class="text-danger">','</p>');
if ($this->form_validation->run()) {
$data['status'] = true;
$pro_data = array(
'pname' => $this->input->post('pro_name'),
'pprice' => $this->input->post('pro_price'),
'pdesc' => $this->input->post('pro_desc'),
'pimage' =>$this->input->post('dropzone'),
'catid' => $this->input->post('pro_cat'),
);
$this->B_menu->add($pro_data);
} else {
foreach ($_POST as $key => $value) {
$data['msg'][$key] = form_error($key);
}
}
echo json_encode($data);
}
//to check the selected value for category
function check_default($post_string)
{
return $post_string == '0' ? FALSE : TRUE;
}
//to upload the image to the correct path
public function validate_image() {
$config = array(
'allowed_types'=>'jpg|png|gif',
'upload_path'=> realpath(APPPATH . '../skin/images'),
'max_size'=>1
);
$this->load->library('upload', $config);
if (!$this->upload->do_upload('dropzone'))
{
$this->form_validation->set_message('validate_image',$this->upload->display_errors());
} else {
$file_info = $this->upload->data();
$img = $file_info['file_name'];
return $img;
}
}

public function validate_image()
{
/* Start: Image Uploading */
$baseurl = $this->config->base_url();
$profile_photo = "";
$profile_path = '';
$config['upload_path'] = './assets/profile_pictures';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '0';
$config['max_width'] = '0';
$config['max_height'] = '0';
if (!empty($_FILES))
{
$this->file_ext = pathinfo($_FILES['image']['name'], PATHINFO_EXTENSION);
$this->file_name = time() . "." . $this->file_ext;
$config['file_name'] = $this->file_name;
$this->load->library('upload', $config);
$this->upload->initialize($config);
if (!$this->upload->do_upload('image', FALSE))
{
echo $this->upload->display_errors();
$this->form_validation->set_message('checkdoc', $data['error'] = $this->upload->display_errors());
if ($_FILES['image']['error'] != 4)
{
return false;
}
}
else
{
$profile_photo = $this->file_name;
$profile_path = $baseurl . "assets/profile_pictures";
return $profile_photo;
}
}
/* End: Image Uploading */
To add-ons I am just saving file name as current timestamp thats it. Also return $imagename and also try to echo this
echo $this->upload->display_errors();
