ci检测是ajax还是页面post提交数据的方法,ciajax

本文实例讲述了ci检测是ajax还是页面post提交数据的方法。分享给大家供大家参考。具体实现方法如下:

一、问题:

因为项目需要我们希望知道提交数据来源是由ajax提交过来的数据还是由页面的post提交过来的数据从而进行不同层面上的处理。

二、解决方法:

在php中解决方法如下:
如果是ajax请求,以下表达式的值为真

复制代码 代码如下:

$_SERVER["HTTP_X_REQUESTED_WITH"]=="XMLHttpRequest"


就是一个PHP的环境变量。

ci中处理办法:

复制代码 代码如下:

define('IS_AJAX', isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest');
define("IS_POST", strtolower($_SERVER['REQUEST_METHOD']) == 'post');

记得在用THINKPHP的时候有内置两个常量 IS_AJAX 与 IS_POST,想在ci中使用查了半天好像没有找到,那就自动动手丰衣足食
在项目的config/constants.php 配置文件加上上边两行代码,这下你就可以在所有的方法中直接调用
例如:

复制代码 代码如下:

if(IS_POST){
 ...
}
if(IS_AJAX){
...
}

希望本文所述对大家的CI框架程序设计有所帮助。
