Creating thumbnails of multiple images? - image

Question

I am uploading max 5 images and i want to create the thumbnails of those 5 images i am successful in uploading and saving image name in database but can't able to make thumbnails.
//controller
$files = $_FILES;
$cpt = count($_FILES['uploadfile']['name']);
for($i=0; $i<$cpt; $i++)
{
$_FILES['uploadfile']['name']= $files['uploadfile']['name'][$i];
$_FILES['uploadfile']['type']= $files['uploadfile']['type'][$i];
$_FILES['uploadfile']['tmp_name']= $files['uploadfile']['tmp_name'][$i];
$_FILES['uploadfile']['error']= $files['uploadfile']['error'][$i];
$_FILES['uploadfile']['size']= $files['uploadfile']['size'][$i];
$this->upload->initialize($this->set_upload_options());
$this->upload->do_upload('uploadfile');
$upload_data = $this->upload->data();
$name_array[] = $upload_data['file_name']; //success till here now inserting in database and creating thumbnails
$fileName = $upload_data['file_name'];
$images[] = $fileName;
}
$fileName = $images;
var_dump($images);
#$form['picture1']=$images[0];
#$form['picture2']=$images[1];
#$form['picture3']=$images[2];
#$form['picture4']=$images[3];
#$form['picture5']=$images[4];
//
private function set_upload_options()
{
// upload an image options
$config = array();
$config['upload_path'] = LARGEPATH; //give the path to upload the image in folder
$config['remove_spaces']=TRUE;
$config['encrypt_name'] = TRUE; // for encrypting the name
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '78000';
$config['overwrite'] = FALSE;
return $config;
}
now i want as 5 images are uploaded in folder at the same time thumbnails of those 5 images are created.

Answer 1

You can use CodeIgniter's Image Manipulation Class for thumbnails creation: check CodeIgniter 3 manual

Answer 2

i found my solution :
private function _makeThumb($source, $filename, $num = 5)
{
$config2['image_library'] = 'gd2';
$config2['source_image'] = $source;
$config2['new_image'] = THUMBPATH.$filename;
$config2['create_thumb'] = TRUE;
$config2['maintain_ratio'] = TRUE;
$config2['width'] = 75;
$config2['height'] = 50;
return $config2;
}
then i can call this function in a loop to create a thumnails
