嗯，我试图使一个网站，你可以看到，我有困难与"LOAD MORE"按钮，什么我在视觉是，每当有人点击这个按钮，它会通过最好的php代码，告诉数据库加载在5个以上的帖子。
show_posts.php
<?php
$query = $con->query("SELECT * FROM `posts` ORDER BY `id` DESC LIMIT 5");
if( isset( $_POST['load'] ) ){
//code goes here
}
while($result = mysqli_fetch_assoc($query)){
// if video is empty then echo this line
if($result["video"] == ""){
$account_assoc = $result["account_assoc"];
$result2 = mysqli_fetch_assoc($con->query("SELECT * FROM `Accounts` WHERE username='$account_assoc' OR email='$account_assoc'"));
if($result2["username"] == ""){
$identifier = $result2["firstname"];
}else{
$identifier = $result2["username"];
}
if($result2['image'] == ""){
$image = "http://jnvbaghmara.nic.in/images/staff/Blank.png";
}else{
$image = 'data:image/jpeg;base64,'.base64_encode($result2['image']);
}
if($result['dislikes'] > 1){
$dislike = "<label style='color: red;'>".format_num($result['dislikes'])."</label> Dislikes";
}else{
$dislike = "<label style='color: red;'>".format_num($result['dislikes'])."</label> Dislike";
}
if($result['likes'] > 1){
$like = "<label style='color: #0096f3;'>".format_num($result['likes'])."</label> likes";
}else{
$like = "<label style='color: #0096f3;'>".format_num($result['likes'])."</label> like";
}

也如果有任何方式使我的代码更简单，那么我是开放的建议。
*我想要的代码是php，因为我了解php比我做js, jquery等
$postsNum = $_GET['num'];
$query = $con->query("SELECT * FROM `posts` ORDER BY `id` DESC LIMIT $postsNum");
