Image manipulation - matchplay - 06-11-2018
I want to resize images using codeigniter image manipulation class. I have tried a few things with no success. I have no errors after running the code below. After the image is uploaded using this code, I manually check to see if the image was resized but they are unchanged from the original size. Can anyone help with this? Is something wrong with the code below?
<?php
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
Class Edit_main_image extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url'));
}
public function do_upload()
{
$config['upload_path'] = 'public/uploads/';
$config['allowed_types'] = 'jpg|png';
$config['max_size'] = 100;
$config['max_width'] = 1024;
$config['max_height'] = 768;
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('mainimg'))
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('templates/header');
$this->load->view('errorpage');
$this->load->view('templates/footer');
}
else
{
unlink($this->input->post('oldimage'));
$this->load->library('image_lib');
$this->image_lib->initialize($config);
$config['image_library'] = 'gd2';
$config['source_image'] = $config['upload_path'].$this->upload->data('file_name');
$config['create_thumb'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 400;
$config['height'] = 350;

For one your using the same config array for both methods, before using the config for the
image lib unset the array then re-initialize it.
SEE The CodeIgniter User's Guide:
Processing an Image
You can use any array name for the config array it doe's not have to be config
just pass the initialize method the right array name.

Thanks! Great advice! I made the changes to my code and now it works. Thanks again. See changes to code below.
//START NEW CODE
$newimg['image_library'] = 'gd2';
$newimg['source_image'] = $config['upload_path'].$this->upload->data('file_name');
$newimg['create_thumb'] = FALSE;
$newimg['maintain_ratio'] = FALSE;
$newimg['width'] = 400;
$newimg['height'] = 375;
$this->load->library('image_lib');
$this->image_lib->initialize($newimg);
$this->image_lib->resize();
//END NEW CODE
// NOW IT WORKS!
