CodeIgniter image upload

When I first time try to write code for image upload on Codeigniter, I had to face problems. I dig and dig and dig. I search on CI guide. but, thats not enough to help me. Well, finally I did it.  If someone stuck on CI image upload, hope it will help them a lot.

There are some easy steps to upload image on CI :

• Create the form normally how it should create for upload a photo on php.  Must add “enctype=”multipart/form-data”
• open controler file. under the upload image function write down following code :

$config[ 'upload_path' ] =  ‘./uploads/’ ;  // destination folder path

$config[ 'allowed_types' ]  =  ‘gif|jpg|png’ ; // Allowed uploaded file type

$config[ 'max_size' ]    =  ‘2048′ ;// Allowed uploaded file’s max size

$this->load->helper( array(  ‘form’ ,  ‘url’ ) ) ;

$this->load->library( ‘upload’ ,  $config);

$image_up = $this->upload->do_upload(‘image‘);

$image_data =  array(‘upload_data’ => $this->upload->data());

• $image_up is where image upload information will be safe, it will return 1 if image uploaded successfully.
• $config is very important variable. for details of  “$config” variable’s parameters  you must have to see the manual
• $image_data will carry the uploaded image information.
• BLUE marked words are library function.
• image is form name
