php 收不到post数据,但是浏览器中显示提交了

Jun 06, 2016 pm 08:29 PM
php

这里是提交的代码:

<code> $.ajax({
        url:"chuli.php",
        method:"POST",
        data:{id:name}
    });
            </code>
Copy after login
Copy after login

这里是接收的代码(chuli.php):

<code>$a=$_POST;
print_r($a);
</code>
Copy after login
Copy after login

这里是浏览器中显示的信息,应该提交了的

php 收不到post数据,但是浏览器中显示提交了

但是在chuli.php中就是接收不到,打印出来的数组为空。

<code>                                                                非常感谢您的阅读。

找到问题出在哪里了,因为是ajax,所以chuli.php不能直接将数组打印出来。

可以在发出请求的代码中加入function(msg){alert(msg);如下:

<code>        $.post(
          "chuli.php",{id:wo},function(msg){alert(msg);}
        )</code>
Copy after login

这样就可以看到发出post之后,浏览器弹出的窗口是有内容的。

另外:将chuli.php收到的内容存储到文件中时,必须指定数组的下标,例如:$a[id];在不指定的情况下,写入文件的只是Array这几个字符,并没有实际数据。

你要在ajax的success方法中
控制台输出或者alert你的php端数据。
你是ajax请求,当然php是空

$_POST['id']

var_dump($_POST);
可以把POST的所有东西全打印出来。
还能判断是不是空数组,然后就知道是哪里的问题了。

ajax没有接收服务器端返回的数据

contentType:"application/x-www-form-urlencoded",
参数加上这个

可能是ContentType的问题,解析不了,Post时候设置下内容试试。
