使用codeigniter调整base64图像的大小

好的,所以使用phonegap我已经构建了一个从iphone库上传图像的应用程序。它将它发送到php脚本,该脚本解码base64图像并写入文件。我现在的问题是它是一个base64图像,我需要复制它并用代码点火器调整它的大小。就像我说它写文件很好,但无法读取文件来调整大小。

到目前为止,这是我的代码:

if ($_POST['image']) {
    // convert the image data from base64
    $imgData = base64_decode($_POST['image']);

    // set the image paths
    $path = './assets/site/images/photo_gallery/';
    $file = md5(date('Ymdgisu')) . '.jpg';
    $file_path = $path . $file;

    $title = trim($_POST['title']);
    $description = trim($_POST['description']);
    $username = trim($_POST['username']);

    $galID = $this->model_mobile->get_user_galID($username);
    if($galID){
        $galleryID = $galID[0]->galleryid;

        write_file($path . $galleryID . '/' . $file, $imgData);
        $data = array (
            'date_added' => date('o-m-d H:i:s'),
            'parentuid' => $galleryID,
            'image_url' => $file,
            'title' => $title,
            'description' => $description,
            'gallery_face' => 0,
            'active' => 1
        );
        $config['source_image'] = '/assets/site/images/photo_gallery/' . $galleryID . '/' . $file;
        $config['quality'] = '100%';
        $config['new_image'] = '/assets/site/images/photo_gallery/' . $galleryID . '/s_' . $file;
        $config['maintain_ratio'] = TRUE;
        $config['master_dim'] = 'width';
        $config['width'] = 200;
        $config['height'] = 150;
        $this->image_lib->initialize($config);
        $this->image_lib->resize();
        //$this->db->insert('table', $data);

        echo 1;
    }else{
        echo 0;
    }

}else {
    echo 0;
 }
 }

更新:我已经解决了这个问题! 在我的js文件中,我将图像数据发送为base64编码。它已经是。所以只需发送数据,然后像上面的PHP一样解码,工作完美。 希望这有助于某人!
