public function update_post($data, $id)

由于do_upload()没有声明文件字段的名称，我不确定上传的内容。在这种情况下，我认为它是userfile，例如do_upload('userfile')。

考虑使用文件上传错误变量做一些事情，因为这应该很快就发现了你的错误。

编辑：

我上传的do_upload()默认文件名参数userfile为form_open_multipart。我现在猜测它为什么不起作用是你的更新＆＃34;表格，不使用private function upload_image() { // Upload Image $config['upload_path'] = './assets/images/posts'; $config['allowed_types'] = 'gif|jpg|jpeg|png'; $config['max_size'] = '2048'; $config['max_width'] = '2000'; $config['max_height'] = '2000'; $this->load->library('upload', $config); if(!$this->upload->do_upload()) { throw new Exception($this->upload->display_errors()); //$errors = array('error' => $this->upload->display_errors()); //$post_image = 'noimage.jpg'; } else { $upload_data=$this->upload->data(); $post_image=$upload_data['file_name']; } return $post_image; }！

请注意：您还可以将重定向功能移回登录控制器构造函数。这将消除一些重复代码行。

此外，如果您正在寻找 easy 方式来获取上传功能的错误，您可以执行以下操作：

try {
    $this->upload_image();
} catch (Exception $e) {
    show_error($e->getMessage());
}

用法：

for (var i = 0; i = exercise.exercise.length; i++){
