Excel导入

　html代码：

<button id="upload" type="button"> 导入数据</button>

jquery代码：

$('#upload').click(function() {
    ajaxFileUpload();
});

function ajaxFileUpload() {
     $.ajaxFileUpload({
        url: "<{:U('ServiceQuestions/upload_file')}>", //用于文件上传的服务器端请求地址
        secureuri: false, //是否需要安全协议，一般设置为false
        fileElementId: 'file2', //文件上传域的ID
        dataType: 'text', //返回值类型 一般设置为json
        success: function(data, status) //服务器成功响应处理函数
            {
                var str = data;
                var data_array = data.split(",");
                if (data_array[0] != 0) {
                    layer.msg(data_array[1], {
                        time: 1000
                    });
                } else if (data_array[0] == 0) { //上传成功
                    layer.msg(data_array[1], {
                        time: 1000
                    });
                }
            },
        error: function(data, status, e) //服务器响应失败处理函数
            {
                alert("网络错误");
            }
    })
    return false;
}

后端php代码：

    $tmp_file = $_FILES ['file-2'] ['tmp_name'];
    $file_types = explode(".", $_FILES ['file-2'] ['name']);
    $upload_type = $_FILES['file-2']['type'];
    $file_type = $file_types [count($file_types) - 1];

    if ($file_type != 'xlsx' and $upload_type != $excel_type) {
        $res['error'] = '1';
        $res['msg'] = '不是Excel文件，请重新上传';
        echo implode($res, ',');
        exit;
    } else {
        //上传文件
        $upload_info = $this->uploadOne('tesques');

        if (!$upload_info) {
            $res['error'] = '1';

            echo implode($res, ',');
            exit;

        } else {
            //导入题库
            $result = $this->import_contract($upload_info);
            if ($result) {
                unlink('./Upload/' . $upload_info);

            }
            echo implode($res, ',');
            exit;

    }
}
