PHP上传图片的简单例子(入门参考)

2、admin_upfile.php

                date_default_timezone_set('PRC');
    //这里上传 $upsize判断上传文件的大小
        $uppath = isset($_REQUEST["upPath"]) ? $_REQUEST["upPath"] : "/attached/";              //文件上传路径
        $formName = isset($_REQUEST["formName"]) ? $_REQUEST["formName"] : "myform";          //回传到上页面编辑框所在Form的Name
        $editName = isset($_REQUEST["editName"]) ? $_REQUEST["editName"] : $_REQUEST["editName"];              //回传到上页面编辑框的Name
    //转换根目录的路径
        if (strpos($uppath, "/") == 0) {
            $i = 0;
            $thpath = $_SERVER["SCRIPT_NAME"];
            $thpath = substr($thpath, 1, strlen($thpath));
            while (strripos($thpath, "/") !== false) {
                $thpath = substr($thpath, strpos($thpath, "/") + 1, strlen($thpath));
                $i = ++$i;
            }

            $pp = "";
            for ($j = 0; $j                 $pp .="../";
            }

            $uppaths = $pp . substr($uppath, 1, strlen($thpath));
        }
        $filename = date("y-m-d");
        if (is_dir($uppaths . $filename) != TRUE)
            mkdir($uppaths . $filename, 0777);
    // if(is_dir($filename."/".$ctime)!=TRUE) mkdir($filename."/".$ctime,0777);

        $f = $_FILES['file1'];

        if ($f["type"] != "image/gif" && $f["type"] != "image/pjpeg" && $f["type"] != "image/jpeg" && $f["type"] != "image/x-png") {
            echo "<script>alert('只能上传图片格式的文件');window.close()</script>";
            //echo $f['type'];
            return false;
        }


    //获得文件扩展名
        $temp_arr = explode(".", $f["name"]);
        $file_ext = array_pop($temp_arr);
        $file_ext = trim($file_ext);
        $file_ext = strtolower($file_ext);

    //新文件名
        $new_file_name = md5(date("YmdHis")) . '.' . $file_ext;
        //$new_file_name = md5(date("YmdHis") . '_' . rand(10000, 99999)) . '.' . $file_ext;

        $dest = $uppaths . $filename . "/" . date("ymdhis") . "_" . $new_file_name; //设置文件名为日期加上文件名避免重复 上传目录
        $dest1 = $uppath . $filename . "/" . date("ymdhis") . "_" . $new_file_name; //设置文件名为日期加上文件名避免重复
        $r = move_uploaded_file($f['tmp_name'], $dest);
        if ($f['size'] > 0) {

            echo "<script>window.opener.document." . $formName . "." . $editName . ".value='" . $dest1 . "'</script>";
            echo "<script>alert('图片上传成功');window.close()</script>";
        }
        ?>

3、admin_upload.php

            图片上传_bbs.it-home.org

                        $uppath = isset($_REQUEST["upPath"]) ? $_REQUEST["upPath"] . "/" : "/attached/";              //文件上传路径
            $formName = isset($_REQUEST["formName"]) ? $_REQUEST["formName"] : "myform";          //回传到上页面编辑框所在Form的Name
            $editName = isset($_REQUEST["editName"]) ? $_REQUEST["editName"] : $_REQUEST["editName"];            //回传到上页面编辑框的Name
            ?>




                                                                                                                                                                                                                  
                                                                                                                                                    正在上传文件，请稍候...
