AJAX评论框userid=0？Reply=“？

Question

当我在textarea中输入文本时，它什么也没有出现。它显示：

cveUser名称:jason123User id :1 forum_insert.js?t=1427284551:44 ResponseText{"reply_id":24，"user_id":0，“应答”：“”，“用户名”：“jason123”，“profile_img”：“/订票/图像/user.png”}

user_id和reply不工作。

forum_insert.php

<?php

    if(isset($_POST['task']) && $_POST['task'] == 'forum_insert')
    {

        $user_id =(int) $_POST['user_id'];
        $reply =addslashes(str_replace("\n", "<br>" , $_POST['reply-text']));

        $std = new stdClass();
        $std->reply_id = 24;
        $std->user_id = $user_id;
        $std->reply = $reply;
        $std->username = "jason123";
        $std->profile_img = "/booking/images/user.png";

        echo json_encode($std);

    }
    else
    {
        header('Location: /booking/forumrm.php');
    }
?>

forum_insert.js

$(document).ready(function(){

$('#reply').click(function(){
    reply_click();
});
});

function reply_click(){

    //text within textarea which the person has entered.
    var text = $('#reply-text').val();
    var user_id = $('#user_id').val();
    var username = $('#username').val();




    if(text.length >0 && user_id != null)
    {
        $('.forum-insert-container').css('border','1px solid #e1e1e1' );
        console.log(text + "User name :" + username + "User id :" + user_id);

        $.post("/booking/forum_insert.php" ,
        {   
            task :"forum_insert",
            userId : user_id,
            reply : text
        }

        )

        .error(
            function()
            {
                console.log("Error");
            }
        )

        .success(

            }
        );



    }
    else{
        $('.forum-insert-container').css('border','1px solid blue' );
        console.log("The text area was empty");
    }


    //remove text from textarea. 
    $('#reply-text').val("");
};      

function forum_insert(data)

Answer 1

您使用的是userId而不是user_id

$.post("/booking/forum_insert.php" ,
        {   
            task :"forum_insert",
            userId : user_id,
            reply : text
        }

$user_id =(int) $_POST['user_id'];

把它改成

$user_id =(int) $_POST['userId'];

也一样

$reply =addslashes(str_replace("\n", "<br>" , $_POST['reply-text']));

至

$reply =addslashes(str_replace("\n", "<br>" , $_POST['reply']));
