CodeIgniter中同时有多个缩略图

Question

目前,我正在学习和尝试CodeIgniter能够做到的事情.但我立刻坚持制作多个缩略图.也许,我使用Wordpress搞砸了太多脑袋,并试图在Codeigniter中做这样的事情,但无论如何,这是我的代码

<?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();
    }
}
}

目前,我能够自己创建一个图像,但我不能用这个缩略图.也许有人可以增强代码,让它工作:)

PS - 我试过把$ image_sizes之后的所有内容,把它放在其他独立的php文件中,运行它,并将var转储到foreach里面的$ config,它似乎正在工作.

像这样使用它:

$this->load->library('image_lib');
foreach ($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比使用$config.加载库更好.
