Question

我是php CodeIgniter（3.1.4）框架的新手。现在我在一个项目工作。在我的项目中，我需要上传图片。我写了一个上传图片的方法。它在我的本地主机上完美运行。但是当我在我的网站（共享主机）中托管我的项目时，我遇到了500错误。我在下面给出了我的代码和文件结构权限。文件权限：应用程序（0755），资产（0755），上传（0755）

代码 - ＆GT; 控制器：

public function save_carousel_image() {
    if (!empty($this->session->userdata('user_session'))) {
        $path = '';
        $new_name = $_FILES["image"]['name'];
        $config['file_name'] = $new_name;
        $config['upload_path'] = './assets/uploads/carousel_images/';
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = 2048;
        $this->load->library('upload', $config);
        $carousel_image_name = trim($this->input->post('carousel_image_name'));
        if (!$this->upload->do_upload('image')) {
            $error = array('error' => $this->upload->display_errors());
            echo 'You did not select a file to upload.';
        } else {
            $carousel_image_name = trim($this->input->post('carousel_image_name'));
            $data = array('upload_data' => $this->upload->data());
            $path = 'assets/uploads/carousel_images/' . $data['upload_data']['file_name'];
            $data = array(
                'carousel_image_name' => $carousel_image_name,
                'carousel_image_path' => $path
            );
            $this->Carousel_image_Model->db->insert('carousel_image', $data);
            redirect(base_url('admin/carousel_image'));
        }
    } else {
        redirect(base_url('admin/user_login'));
    }
}

视图 - ＆GT;

<div class="form-group">
    <span class="btn btn-success fileinput-button">
        <i class="fa fa-upload"></i>
        <span>Upload File</span>
        <input type="file" name="image" id="image" onchange="readURL(this)"  >
    </span>
</div><div class="card" style="background-color: white;">
    <img id="bannerImage" src="" height="300px" width="300px">
</div><script>
function readURL(input) {
    if (input.files && input.files[0]) {
        var reader = new FileReader();
        reader.onload = function (e) {
            $('#bannerImage').addClass('image-preview');
            $('#bannerImage').attr('src', e.target.result);
        };
        reader.readAsDataURL(input.files[0]);
    }
}
