thinkphp3.2实现上传图片的控制器方法

本文讲述了thinkphp3.2实现上传图片的控制器方法。分享给大家供大家参考，具体如下：

public function file(){  $baseUrl = str_replace('//', '/', dirname($_SERVER['SCRIPT_NAME']));  import('ORG.Net.UploadFile');  import('ORG.Util.Services_JSON');  $upload = new UploadFile();  $upload->maxSize = 3145728;  $upload->allowExts = array('jpg', 'gif', 'png', 'jpeg');  $upload->savePath = './uploads/Images/';  $info = $upload->uploadOne($_FILES['imgFile']);  $file_url = $baseUrl . 'uploads/Images/' . $info['0']['savename'];  if ($info) {   header('Content-type: text/html; charset=UTF-8');   $json = new Services_JSON();   echo $json->encode(array('error' => 0, 'url' => $file_url));   exit;  } else {   $this->error($upload->getErrorMsg());  }}public function file_manager(){  import('ORG.Util.Services_JSON');  $php_path = dirname(__FILE__) . '/';  $php_url = dirname($_SERVER['PHP_SELF']) . '/';  $root_path = $php_path . './uploads/Images/';  $root_url = $php_url . './uploads/Images/';  $ext_arr = array('gif', 'jpg', 'jpeg', 'png', 'bmp');  $dir_name = emptyempty($_GET['dir']) ? '' : trim($_GET['dir']);  if (!in_array($dir_name, array('', 'image', 'flash', 'media', 'file'))) {   echo "Invalid Directory name.";   exit;  }  if ($dir_name !== '') {   $root_path .= $dir_name . "/";   $root_url .= $dir_name . "/";   if (!file_exists($root_path)) {    mkdir($root_path);   }  }//根据path参数，设置各路径和URL  if (emptyempty($_GET['path'])) {   $current_path = realpath($root_path) . '/';   $current_url = $root_url;   $current_dir_path = '';   $moveup_dir_path = '';  } else {   $current_path = realpath($root_path) .

'name' : strtolower($_GET['order']);//不允许使用..移动到上一级目录  if (preg_match('//././', $current_path)) {   echo 'Access is not allowed.';   exit;  }//最后一个字符不是/  if (!preg_match('///$/', $current_path)) {   echo 'Parameter is not valid.';   exit;  }//目录不存在或不是目录  if (!file_exists($current_path) || !is_dir($current_path)) {   echo 'Directory does not exist.';   exit;  }//遍历目录取得文件信息  $file_list = array();  if ($handle = opendir($current_path)) {   $i = 0;   while (false !== ($filename = readdir($handle))) {    if ($filename{0} == '.') continue;    $file = $current_path . $filename;    if (is_dir($file)) {     $file_list[$i]['is_dir'] = true; //是否文件夹     $file_list[$i]['has_file'] = (count(scandir($file)) > 2); //文件夹是否包含文件     $file_list[$i]['filesize'] = 0; //文件大小     $file_list[$i]['is_photo'] = false; //是否图片     $file_list[$i]['filetype'] = ''; //文件类别，用扩展名判断    } else {     $file_list[$i]['is_dir'] = false;     $file_list[$i]['has_file'] = false;     $file_list[$i]['filesize'] = filesize($file);     $file_list[$i]['dir_path'] = '';     $file_ext = strtolower(pathinfo($file, PATHINFO_EXTENSION));     $file_list[$i]['is_photo'] = in_array($file_ext, $ext_arr);     $file_list[$i]['filetype'] = $file_ext;    }    $file_list[$i]['filename'] = $filename; //文件名，包含扩展名    $file_list[$i]['datetime'] = date('Y-m-d H:i:s', filemtime($file)); //文件最后修改时间    $i++;   }   closedir($handle);  }//排序  usort($file_list, 'cmp_func');  $result = array();//相对于根目录的上一级目录  $result['moveup_dir_path'] = $moveup_dir_path;//相对于根目录的当前目录  $result['current_dir_path'] = $current_dir_path;//当前目录的URL  $result['current_url'] = $current_url;//文件数  $result['total_count'] = count($file_list);//文件列表数组  $result['file_list'] = $file_list;//输出JSON字符串  header('Content-type: application/json; charset=UTF-8');  $json = new Services_JSON();  echo $json->encode($result);}
