我将尝试删除评论回复，其中有 parent_id = 0
已修复。我可以删除父注释，但是当我删除子注释（回复）时，父注释已删除，但子注释未删除。并且除非我刷新，否则答复注释仍保留在数据库中并显示在页面中它。 我有获取评论和回复这样的功能
<?php

$result = $db->select($commentQuery);
$commentReply='';

?>
<?php
$commentReply .= '

我尝试使用ajax删除回复评论
$(document).on('click','.delClick',function (e) {
e.preventDefault();
var element = $(this).parent().parent();
var del_id = $(this).attr('id');
$.ajax({
url:"../scripts/disqus_template.php",
type: "POST",
data: "id=" + del_id,
dataType: "JSON",
cache: false,
success: function (response){
if(response.error) {
$('#delmessage').fadeIn('500').html(response.message);
$('#delmessage').fadeOut('500').html(response.message);
$('#delmessage').fadeIn('500').html(response.message);
$('#delmessage').fadeOut('500').html(response.message);
//$('#delmessage').fadeIn('500').html(response.message);
//$('#delmessage').fadeOut('500').html(response.message);
element.slideUp('slow', function() {$(this).remove();});
if($("#countNumber").length > 0) {
var currentCount = parseInt($("#countNumber").text());
var newCount = currentCount - 1;
$("#countNumber").text(newCount)
}
}
}
});
return false;
// return false;
});
用于删除像这样的注释的php脚本->
<?php
require_once __DIR__.'/../vendor/autoload.php';
include __DIR__.'/../lib/Session.php';
//include __DIR__.'/../scripts/disqus.php';
include __DIR__.'/../config/config.php';
include __DIR__.'/../lib/Database.php';
//Session:: init();
$db = new Database();
//var_dump($id);
//die();
$commentQuery = "SELECT * FROM `comment` WHERE `comment`.`parent_id`= 0";
if( $result = $db->select($commentQuery))
{
$delResult = mysqli_num_rows( $result);
if(!empty($delResult)|| $delResult>0)
{
if($cmResult =$result ->fetch_assoc())
{
//$reply= 1;
$id = $cmResult['id'];
$parentId = $cmResult['parent_id'];
if($id)
{
$delete = "DELETE FROM comment WHERE `comment`.`id`='".$id."'";
$result= $db->delete($delete);
if($result)
{
$msg = "<p class='alert alert-success'>.<span class='fa-layers fa-fw'>.
<i class='fas fa-check-circle fa-2x'></i></span>success</p>";
$status = array
(
'error' => 3,
'message' => $msg
);
} else {
$msg = "<p class='alert alert-danger'>.<i class='fas fa-times-circle fa-
2x'>.</i>deny</p>";
$status = array
(
'error' => 4,
'message' => $msg
);
}
}
echo json_encode($status);
}
}
}
但是那不走运。我想我没有得到一个简单的东西，眨眼之间。
