CodeIgniter from Scratch: Day 9 Tutorial Problems displaying images - El Forum - 12-28-2011
[eluser]Unknown[/eluser]
Hi,
I've been following the codeigniter from scratch tutorial on how to upload and display images and found them very worthwhile, however I have been having issues with the displaying images section of the tutorial. The files upload without issue to the correct folder but I cannot make them display. I believe the function getimages is not working correctly in my code but I'm not sure how to fix it.
http://net.tutsplus.com/tutorials/php/codeigniter-from-scratch-file-uploading-and-image-manipulation/
Can anyone see where I am going wrong?
Any help is greatly appreciated!!
My config file looks as follows
$config['index_page'] = 'lab06_spacebook.php';
My .htaccess file is as follows
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ lab06_spacebook.php?/$1 [L]
Heres a copy of my code
Model

<?php
class Gallery_Model extends CI_Model
{
var $gallery_path;
var $gallery_path_2;
function Gallery_Model()
{
parent::__construct();
$this->gallery_path=realpath(APPPATH .'../lab06_spacebook/assets');
$this->gallery_path_2=base_url() .'assets';
}
function do_upload() {
$config = array(
'allowed_types' => 'jpg|jpeg|gif|png',
'upload_path' => $this->gallery_path
);
$this->load->library('upload', $config);
$this->upload->do_upload();
$image_data = $this->upload->data();
$config = array(
'source_image' => $image_data['full_path'],
'new_image' => $this->gallery_path .'/thumbs',
'maintain_ration' =>true,

$this->load->library('image_lib', $config);
$this->image_lib->resize();
}
function get_images(){
$files = scandir($this->gallery_path);
$files = array_diff($files,array('.', '..', 'thumbs'));
$images = array();
foreach ($files as $file)
{
$images[]=array(
'url' =>$this->gallery_path_2 . $file,
'thumb_url' =>$this->gallery_path_2 .'thumbs/'. $file,
);
}
return $images;
