Step 2: Create Routes
application/config/routes.php
<?php defined('BASEPATH') OR exit('No direct script access allowed'); $route['default_controller'] = 'welcome'; $route['404_override'] = ''; $route['translate_uri_dashes'] = FALSE; $route['image-upload'] = 'ProfilePicUpload'; $route['image-upload/post']['post'] = "ProfilePicUpload/storeProfileDP";
Step 3: Create ProfilePicUpload Controller
application/controllers/ProfilePicUpload.php
<?php class ProfilePicUpload extends CI_Controller { /** * Manage __construct * * @return Response */ public function __construct() { parent::__construct(); $this->load->helper(array('form', 'url')); } /** * Manage index * * @return Response */ public function index() { $this->load->view('profileDpFormLoadData', array('error' => '' )); } /** * Manage storeProfileDP * * @return Response */ public function storeProfileDP() { $config['upload_path'] = './uploads/'; $config['allowed_types'] = 'gif|jpg|png'; $config['max_size'] = 1024; $this->load->library('upload', $config); if ( ! $this->upload->do_upload('image')) { $error = array('error' => $this->upload->display_errors()); $this->load->view('profileDpFormLoadData', $error); }else { $uploadedImage = $this->upload->data(); $this->resizeImage($uploadedImage['file_name']); print_r('Image Uploaded Successfully.'); exit; } } /** * Manage storeProfileDP * * @return Response */ public function resizeImage($filename) { $source_path = $_SERVER['DOCUMENT_ROOT'] . '/uploads/' . $filename; $target_path = $_SERVER['DOCUMENT_ROOT'] . '/uploads/thumbnail/'; $config_manip = array( 'image_library' => 'gd2', 'source_image' => $source_path, 'new_image' => $target_path, 'maintain_ratio' => TRUE, 'create_thumb' => TRUE, 'thumb_marker' => '_thumb', 'width' => 150, 'height' => 150 ); $this->load->library('image_lib', $config_manip); if (!$this->image_lib->resize()) { echo $this->image_lib->display_errors(); } $this->image_lib->clear(); } } ?>
Step 4: Create View File
application/views/profileDpFormLoadData.php
<!DOCTYPE html> <html> <head> <title>Codeignier 3 Image Upload with Resize Example from Scratch - www.pakainfo.com</title> </head> <body> <?php echo $error;?> <?php echo form_open_multipart('image-upload/post');?> <input type="file" name="image" size="20" /> <input type="submit" value="upload" /> </form> </body> </html>
Now i requred to make 2 main folder. First you have to make “uploads” and inside uploads folder you have to make second new folder “thumbnail”.
