Question

At the moment at once I’m learning and trying, to what CodeIgniter is able to. But I stuck at multiple thumbnails making at once. Probably, I messed up my head too much using WordPress, and trying to do something like this in Codeigniter, but anyways, here is my code

<?php

class Gallery_model extends CI_Model {

var $gallery_path;

function __construct() {
    parent::__construct();
    $this->load->helper('functions');
    $this->gallery_path = realpath(APPPATH . '../uploads');
}

function do_upload() {

    $config = array(
        'allowed_types' => 'jpg|jpeg|gif|png',
        'upload_path' => $this->gallery_path,
        'max_size' => 2000
    );

    $this->load->library('upload', $config);
    $this->upload->do_upload();
    $image_data = $this->upload->data();


    $image_sizes = array(
        'thumb' => array(150, 100),
        'medium' => array(300, 300),
        'large' => array(800, 600)
    );

    foreach ($image_sizes as $resize) {

        $config = array(
            'source_image' => $image_data['full_path'],
            'new_image' => $this->gallery_path . '-' . $resize[0] . 'x' . $resize[1],
            'maintain_ration' => true,
            'width' => $resize[0],
            'height' => $resize[1]
        );

        $this->load->library('image_lib', $config);
        $this->image_lib->resize();
    }
}
}

At the moment, I’m able to create just an image it self, but I cant make thumbnails with this. Maybe someone could enhance the code, and get it work 🙂

PS – I tried just take everything after $image_sizes, put it in other independent php file, run it, and var dump the $config inside of foreach, and it seemed like working.

Use it like this:

$this->load->library('image_lib');
foreach ($image_sizes as $resize) {

    $config = array(
        'source_image' => $image_data['full_path'],
        'new_image' => $this->gallery_path . '-' . $resize[0] . 'x' . $resize[1],
        'maintain_ration' => true,
        'width' => $resize[0],
        'height' => $resize[1]
    );

    $this->image_lib->initialize($config);
    $this->image_lib->resize();
    $this->image_lib->clear();
}

initialize works better than loading the library with the $config.
