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 \ 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'];
$currder']) ? 'name' : strtolower($_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); }
希望本文所述对大家基于ThinkPHP框架的PHP程序设计有所帮助。
