来自ajax调用的JSON输入的意外结束

I've been working on a delete post functionality in my project. It all works fine in PHP, but now I'd like to do that in Ajax, to prevent the refresh and all.

我一直在研究项目中的删除帖功能。它在PHP中运行良好,但现在我想在Ajax中这样做,以防止刷新和所有。

Anyway, when I perform my ajax call, I get an error:

无论如何,当我执行我的ajax调用时,我收到一个错误:

SyntaxError: Unexpected end of JSON input
at Object.parse (native)
at n.parseJSON (http://localhost/imdstagram/public/js/jquery-2.2.3.min.js:4:6401)
at Ab (http://localhost/imdstagram/public/js/jquery-2.2.3.min.js:4:8347)
at z (http://localhost/imdstagram/public/js/jquery-2.2.3.min.js:4:11804)
at XMLHttpRequest.<anonymous> (http://localhost/imdstagram/public/js/jquery-2.2.3.min.js:4:15680)

It says that this error is on line 35, line 35 sends me to

它说这个错误在第35行,第35行发给我

console.log(error);

Anyway, to give you a better view, here is my Ajax call:

无论如何,为了给你一个更好的视图,这是我的Ajax调用:

$(document).ready(function(){

    $(".post__delete").on("click", function(e){
        var postDeleteID = $('.deleteID').val();

        $.ajax({
            url: "ajax/deletePost.php", 
            type: "POST",             
            data: JSON.stringify(postDeleteID),
            dataType: 'json',
            contentType: false,
            cache: false,
            processData: false,
            success: function(data)
            {

            },
            error: function (request, status, error) {
                console.log(error);
            }
        });

        e.preventDefault();
    });
});

And my deletePost.php code:

我的deletePost.php代码:

<?php
    include_once("../classes/Post.class.php");
    session_start();
    $post = new Post();

    if(!empty($_POST)){
        $deletePostID = $_POST['deletePostID'];

        $post->deletePost($deletePostID);

        if($post->deletePost($deletePostID)){
            $status['delete'] = "success";
        } else {
            $status['delete'] = "failed";
        }

        header('Content-Type: application/json; charset=utf-8', true);
        echo json_encode($status);
    }

?>

I've tried many things like changing the dataType and contentType, but nothing seems to work out.

我尝试过很多改变dataType和contentType的东西,但似乎没有任何结果。

4 个解决方案

#1

Your request is wrong, you should not be sending json if you expect to use the $_POST super global. Send it as regular url encoded form data

您的请求是错误的,如果您希望使用$ _POST超级全局,则不应发送json。将其作为常规url编码的表单数据发送

    $.ajax({
        url: "ajax/deletePost.php", 
        type: "POST",             
        data: {postDeleteID: postDeleteID},
        dataType: 'json',
        cache: false,
        success: function(data)
        {

        },
        error: function (request, status, error) {
            console.log(error);
        }
    });

#2

Try to change the dataType to 'text' and contentType to 'application/json'

尝试将dataType更改为'text',将contentType更改为'application / json'

#3

You are "deleting" the post twice.

您正在“删除”该帖子两次。

Remove this line: $post->deletePost($deletePostID);

删除此行:$ post-> deletePost($ deletePostID);

#4

This is a very strange problem within frameworks and PHP in general, in your controller just:

这在框架和PHP中是一个非常奇怪的问题,通常在你的控制器中:

echo(json_encode($status));

Has worked for me ..

为我工作过..
