Codeigniter 缩略图数组不起作用

Question

我正在上传多个文件，工作正常。我得到了两个图像，但另一个图像是缩略图，没有得到它们的给定路径，也没有改变为缩略图大小。

我希望 "thumbnail creation start" 区域的缩略图有问题。检查我的阵列，让我知道我的错误。

控制器代码

public function addimage($room_id)
{
    $name_array = array();
    $count = count($_FILES['userfile']['size']);
    foreach($_FILES as $key=>$value)
    for($s=0; $s<=$count-1; $s++) 
    {
        $_FILES['userfile']['name']=$value['name'][$s];
        $_FILES['userfile']['type']    = $value['type'][$s];

        $config['upload_path'] = './uploads/';

        $this->load->library('upload', $config);

        $this->upload->do_upload();
        $data = $this->upload->data();
        $name_array[] = $data['file_name']; // get file names for first file

    $this->rooms_model->room_images_insert($options);
    redirect('/admin/rooms', 'location');
} //end of function

Answer 1

在你对你的图像进行配置后，即设置你的图像属性，然后你应该清除并初始化 image_lib 才能生效。

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

注：

确保 $config 或 $config1
确保 source_image 路径正确

Answer 2

替换

$config1['source_image'] = $image['full_path'];

至

$config1['source_image'] = $data['full_path'];

同时删除以下注释行

$this->image_lib->resize();
//$this->upload->do_upload();
//$data = $this->upload->data();
