在Codeigniter中上传多个文件

我想用单个元素上传多个文件。 所以我尝试这个例子。

使用CodeIgniter 2.0多个file upload（数组）

这是我的forms

<form enctype="multipart/form-data" class="jNice" accept-charset="utf-8" method="post" action="http://xxxx.dev/admin/add_estates"> <fieldset> <label>Title * : </label> <input type="text" class="text-long" value="" name="title"> <label>Description : </label> <textarea class="mceEditor" rows="10" cols="40" name="description"></textarea> <label>Image : </label> <input type="file" multiple="" name="images[]"> <button class="button-submit" type="submit" name="save" id="">Save</button> </fieldset> </form> 

这是我的控制器

 public function add_estates() { $data['page_title'] = "&copy; IDEAL - Administrator - Real State - Add Real Estate"; $data['main_content'] = 'admin/add_estates'; if ($this->input->post() !== FALSE) { $this->load->library('form_validation'); $this->form_validation->set_rules('title', 'Career Title', 'trim|required'); if ($this->form_validation->run() !== FALSE) { $title = $this->input->post('title'); $description = $this->input->post('description'); if (!empty($_FILES['images']['name'][0])) { if ($this->upload_files($title, $_FILES['images']) === FALSE) { $data['error'] = $this->upload->display_errors('<div class="alert alert-danger">', '</div>'); } } if (!isset($data['error'])) { $this->admin_model->add_estate($title, $description, $image_name); $this->session->set_flashdata('suc_msg', 'New real estate added successfully'); redirect('admin/add_estates'); } } } $data['suc_msg'] = $this->session->flashdata('suc_msg'); $this->load->view('layout_admin', $data); } 

这是我的file upload方法

 private function upload_files($title, $files) { $config = array( 'upload_path' => './upload/real_estate/', 'allowed_types' => 'jpg|gif|png', 'overwrite' => 1, ); $this->load->library('upload', $config); foreach ($files['name'] as $key => $image) { $_FILES['images']['name']= $files['name'][$key]; $_FILES['images']['type']= $files['type'][$key]; $_FILES['images']['tmp_name']= $files['tmp_name'][$key]; $_FILES['images']['error']= $files['error'][$key]; $_FILES['images']['size']= $files['size'][$key]; $config['file_name'] = $title .'_'. $image; $this->upload->initialize($config); if ($this->upload->do_upload($image)) { $this->upload->data(); } else { return false; } } return true; } 

但它给You did not select a file to upload. 每次。 有什么问题？

我根据@Denmark更改了images[]上传方法。

  private function upload_files($path, $title, $files) { $config = array( 'upload_path' => $path, 'allowed_types' => 'jpg|gif|png', 'overwrite' => 1, ); $this->load->library('upload', $config); $images = array(); foreach ($files['name'] as $key => $image) { $_FILES['images[]']['name']= $files['name'][$key]; $_FILES['images[]']['type']= $files['type'][$key]; $_FILES['images[]']['tmp_name']= $files['tmp_name'][$key]; $_FILES['images[]']['error']= $files['error'][$key]; $_FILES['images[]']['size']= $files['size'][$key]; $fileName = $title .'_'. $image; $images[] = $fileName; $config['file_name'] = $fileName; $this->upload->initialize($config); if ($this->upload->do_upload('images[]')) { $this->upload->data(); } else { return false; } } return $images; }

你应该使用这个库在CI中多重上传https://github.com/stvnthomas/CodeIgniter-Multi-Upload

Answer 3

 private function upload_files($path, $title, $files) { $config = array( 'upload_path' => $path, 'allowed_types' => 'jpg|gif|png', 'overwrite' => 1, ); $this->load->library('upload', $config); $images = array(); foreach ($files['name'] as $key => $image) { $_FILES['images[]']['name']= $files['name'][$key]; $_FILES['images[]']['type']= $files['type'][$key]; $_FILES['images[]']['tmp_name']= $files['tmp_name'][$key]; $_FILES['images[]']['error']= $files['error'][$key]; $_FILES['images[]']['size']= $files['size'][$key]; $fileName = $title .'_'. $image; $images[] = $fileName; $config['file_name'] = $fileName; $this->upload->initialize($config); if ($this->upload->do_upload('images[]')) { $this->upload->data(); } else { return false; } } return true; }
