我想创建像facebook或Instagram一样的帖子系统任何人都可以帮助我吗？

我的代码显示我收到了我的帖子信息然后我用它们显示在我的页面中但我现在想要创建一个喜欢和不喜欢的系统

Answer 1

首先你必须在你的帖子表中创建“likeCount”或“dislikeCount”字段，然后提出增加或减少计数的ajax请求。

示例jQuery代码。

$(document).on('click','.vote',function(){
	
	var $this = $(this);
	var $postID = $this.data('post_id');
	var $action = $this.data('vote_type'); //example 'up' or 'down'
	
	$.ajax({

	url:'url/to/process/ajax',
	type:'POST',
	data:{
			action:$action,
			postID : $postID
		},
	dataType:'json',
	success:function(response){
		
		//do success action
		
		},
	error:function(){}	
});
	
	
});
