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) . "/" . $_GET["path"];
   $current_url = $root_url . $_GET["path"];
   $current_dir_path = $_GET["path"];
   $moveup_dir_path = preg_replace("/(.*?)[^/]+/$/", "$1", $current_dir_path);
  }
  echo realpath($root_path);
//排序形式,name or size or type
  $order = emptyempty($_GET["order"]) ? "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);
}
