该程序可以实现:
1.同时上传5张图片
2.同时生成两种尺寸的缩略图
3.保存到mysql
controllers:upload.php文件:
<?php class Upload extends Controller { function go() { if(isset($_POST['go'])) { //初始化 $config['upload_path'] = 'album/source'; $config['allowed_types'] = 'gif|jpg|png|bmp|jpeg'; $config['encrypt_name'] = TRUE; $config['remove_spaces'] = TRUE; $config['max_size'] = '0'; $config['max_width'] = '0'; $config['max_height'] = '0'; $this->load->library('upload', $config); //170*170图片 $configThumb = array(); $configThumb['image_library'] = 'gd2'; $configThumb['source_image'] = ''; $configThumb['create_thumb'] = TRUE; $configThumb['maintain_ratio'] = TRUE; //保持图片比例 $configThumb['new_image'] = 'album/thumb'; $configThumb['width'] = 170; $configThumb['height'] = 170; //600*600图片 $configLarge = array(); $configLarge['image_library'] = 'gd2'; $configLarge['source_image'] = ''; $configLarge['create_thumb'] = TRUE; $configLarge['maintain_ratio'] = TRUE; //保持图片比例 $configLarge['new_image'] = 'album/large'; $configLarge['width'] = 600; $configLarge['height'] = 600; $this->load->library('image_lib'); for($i = 1; $i < 6; $i++) { $upload = $this->upload->do_upload('image'.$i); if($upload === FALSE) continue; $data = $this->upload->data();//返回上传文件的所有相关信息的数组 $uid = $this->session->userdata('uid'); $uploadedFiles[$i] = $data; if($data['is_image'] == 1) { //初始化170*170 $configThumb['source_image'] = $data['full_path']; //文件路径带文件名 $this->image_lib->initialize($configThumb); $this->image_lib->resize(); //初始化600*600 $configLarge['source_image'] = $data['full_path']; //文件路径带文件名 $this->image_lib->initialize($configLarge); $this->image_lib->resize(); } //插入图片信息到album表,插入的文件名为source目录文件名 $picture = array( 'filename' => $data['file_name'], 'albumID' => $this->uri->segment(4,0), 'uid' => $this->session->userdata('uid'), 'dateline' => time(), 'describe' => '', 'click' => 0 ); $this->load->model('album_model'); $this->album_model->AddPic($picture); $picture = array(); } } /* 转出 */ $albumID = $this->uri->segment(4); $backurl = site_url() . 'photo/editpic/album/' .$albumID; $this->session->set_flashdata('msg','图片上传成功.'); redirect($backurl,'refresh'); } }
views:new_pic.view文件:
<form method="post" action="<?php echo site_url() ?>photo/upload/go/<?php echo $albumID ?>" enctype="multipart/form-data"> <input type="file" name="image1" class="files"/><br /> <input type="file" name="image2" class="files"/><br /> <input type="file" name="image3" class="files"/><br /> <input type="file" name="image4" class="files"/><br /> <input type="file" name="image5" class="files"/><br /> <br /> <p><input type="submit" name="go" value="上传照片" class="button" /></p> </form>
此外需要注意:
1.要一次上传几个文件,修改表单和控制器中循环部分的参数就好。
2.album\\source 是上传后原图目录 large和thumb分别是两次执行$this->image_lib->resize();后存放缩略图的目录
3.缩略图文件名如需和album\\source目录一致,请添加参数 $config['thumb_marker'] = '';
4.$picture这部分数组是保存到数据库的东西,可以不用管了。
Codeigniter实现多文件上传并创建多个缩略图
