php - Codeigniter REST 上传多张图片

Question

我完全坚持这个...检查了所有相关的 stackoverflow 帖子，但没有任何帮助。在 Codeigniter 中使用 Phil 的 REST 服务器/客户端设置，可以插入正常条目，但不能上传多张图片，实际上甚至不能上传单张图片。

我真的不知道如何调试 REST 部分，它什么都不返回。

我有这个数组来自 View :

Array
(
    [1] => Array
        (
            [name] => sideshows.jpg
            [type] => image/jpeg
            [tmp_name] => /Applications/MAMP/tmp/php/phppYycdA
            [error] => 0
            [size] => 967656
        )

    [2] => Array
        (
            [name] => the-beer-scale.jpg
            [type] => image/jpeg
            [tmp_name] => /Applications/MAMP/tmp/php/phpCsiunQ
            [error] => 0
            [size] => 742219
        )

    [3] => Array
        (
            [name] => the-little-lace.jpg
            [type] => image/jpeg
            [tmp_name] => /Applications/MAMP/tmp/php/phpXjT7WL
            [error] => 0
            [size] => 939963
        )

    [4] => Array
        (
            [name] => varrstoen-australia.jpg
            [type] => image/jpeg
            [tmp_name] => /Applications/MAMP/tmp/php/phpcHrJXe
            [error] => 0
            [size] => 2204400
        )

)

我正在使用我发现的这个辅助方法来整理多个文件上传:

function multifile_array()
{
    if(count($_FILES) == 0)
        return;

    $files = array();
    $all_files = $_FILES['files']['name'];
    $i = 0;

    foreach ($all_files as $filename) {
        $files[++$i]['name'] = $filename;
        $files[$i]['type'] = current($_FILES['files']['type']);
        next($_FILES['files']['type']);
        $files[$i]['tmp_name'] = current($_FILES['files']['tmp_name']);
        next($_FILES['files']['tmp_name']);
        $files[$i]['error'] = current($_FILES['files']['error']);
        next($_FILES['files']['error']);
        $files[$i]['size'] = current($_FILES['files']['size']);
        next($_FILES['files']['size']);
    }

    $_FILES = $files;

}

此函数正在 API Controller 中调用:

public function my_file_upload_post() {

        if( ! $this->post('submit')) {
            $this->response(NULL, 400);
        }

        $data = $this->post('data');
        multifile_array();

        $foldername = './uploads/' . $this->post('property_id');

        if(!file_exists($foldername) && !is_dir($foldername)) {
            mkdir($foldername, 0750, true);
        }

        $config['upload_path'] = $foldername;
        $config['allowed_types'] = 'gif|jpg|png|doc|docx|pdf|xlsx|xls|txt';
        $config['max_size'] = '10240';

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

        foreach ($data as $file => $file_data) {
            $this->upload->do_upload($file);

            //echo '<pre>';
            //print_r($this->upload->data());
            //echo '</pre>';

      }


        if ( ! $this->upload->do_upload() ) {
            return $this->response(array('error' => strip_tags($this->upload->display_errors())), 404);
        } else {
            $upload = $this->upload->data();
            return $this->response($upload, 200);

        }



    }

我很高兴分享我的代码，我确实设法让多个文件上传不用担心，但只是尝试使用 API 进行设置，以便我可以从外部网站、内部网站或 iPhone 调用它。帮助将不胜感激。

干杯

更新:

这是来自 API Controller 的代码:

function upload_post() {

        $foldername = './uploads/' . $this->post('property_id');

        if(!file_exists($foldername) && !is_dir($foldername)) {
            mkdir($foldername, 0750, true);
        }

        $config['upload_path'] = $foldername;
        $config['allowed_types'] = 'gif|jpg|png|doc|docx|pdf|xlsx|xls|txt';
        $config['max_size'] = '10240';

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

        if ( ! $this->upload->do_upload())
        {
            //return $this->response(array('error' => strip_tags($this->upload->display_errors())), 404);
            return $this->response(array('error' => var_export($this->post('file'), true)), 404);

        }
        else
        {
            $data = array('upload_data' => $this->upload->data());
            return $this->response(array('error' => $data['upload_data']), 404);
        }
return $this->response(array('success' => 'successfully uploaded' ), 200);      
}

如果您直接从表单转到 API，则此方法有效，但您需要在浏览器中输入用户名和密码。如果我通过 Controller 运行它，那么它找不到图像。

这不完全是你要求的，但这是我用来解决这个问题的方法。一个 PHP/jQuery 上传小部件!
