I have made a helper function for me which upload the files and return a array with upload result.It takes a parameter upload directory where to save the files. Here is the my function
function upload_file($save_dir="images")//takes folder name where to save.default images folder
{
$CI = & get_instance();
$CI->load->library('upload');
$config=array();
$config['upload_path'] = FCPATH.$save_dir;
$config['allowed_types'] = 'gif|jpg|png';//only images.you can set more
$config['max_size'] = 1024*10;//10 mb you can increase more.Make sure your php.ini has congifured same or more value like this
$config['overwrite'] = false;//if file do not replace.create new file
$config['remove_spaces'] = true;//remove sapces from file
//you can set more config like height width for images
$uploaded_files=array();
foreach ($_FILES as $key => $value)
{
if(strlen($value['name'])>0)
{
$CI->upload->initialize($config);
if (!$CI->upload->do_upload($key))
{
$uploaded_files[$key]=array("status"=>false,"message"=>$value['name'].': '.$CI->upload->display_errors());
}
else
{
$uploaded_files[$key]=array("status"=>true,"info"=>$CI->upload->data());
}
}
}
return $uploaded_files;
}
Sample output
if you print out the function returns you will get the output like this
Array
(
[file_input_name1] => Array
(
[status] => 1//status will be true if uploaded
[info] => Array //if success it will return the file informattion
(
[file_name] => newfilename.jpg
[file_type] => image/jpeg
[file_path] => C:/Program Files (x86)/VertrigoServ/www/rnd/images/
[full_path] => C:/Program Files (x86)/VertrigoServ/www/rnd/images/newfilename.jpg
[raw_name] => newfilename
[orig_name] => newfilename.jpg
[client_name] => newfilename
[file_ext] => .jpg
[file_size] => 762.53
[is_image] => 1
[image_width] => 1024
[image_height] => 768
[image_type] => jpeg
[image_size_str] => width="1024" height="768"
)
)
[file_input_name_2] => Array
(
[status] =>//if invalid file status will be false with error message
[message] => desktop.ini: <p>The filetype you are attempting to upload is not allowed.</p>
)
)
Hope it may help you
