16.6.5 发帖功能讲解

发贴功能

模板所在位置： /theme/default/addc.html

PHP页面 addc.php

操作流程

1. 用户点击进入发贴页的时候，将所选版块的ID带上。URL示例如下：http://bbs.com/addc.php?classid=5。我们就可以知道用户是向哪个版块发贴。
2. 判断用户是否存在
3. 判断版块是否存在，如果不存在的话，插入的版块即非法。我们让用户发贴不能成功。
4. 展示导航，版块名等基本信息，渲染进入模板
5. 准本好要插入的基本信息，拼接SQL语句，并插入库
6. 判断是否写入成功
7. 成功给用户金币（积分），跳转至贴子页

1. 判断用户是否登陆，未登陆不能发贴

//包含公共组件
include "./common/common.php";

	//判断用户是否登录
	if(!$_COOKIE["uid"])
	{
		$notice = "抱歉，您尚未登录，没有权限在该版块发帖";
		include "close.php";
		exit;
	}

2.判断ID是否存在

	if(empty($_REQUEST["classid"]) || !is_numeric($_REQUEST["classid"]))
	{
		$msg = "<font color=red><b>禁止非法操作</b></font>";
		$url = $_SERVER["HTTP_REFERER"];
		$style = "alert_error";
		$toTime = 3000;
		include "notice.php";
	}
	$classId = $_REQUEST["classid"];

3. 读取版块相关的基本信息

	$category = dbSelect("category","cid,classname,parentid","parentid<>0 and cid=".$classId."","",1);
	if($category){

		$smallName = $category[0]["classname"];
		$smallId = $category[0]["cid"];
		$parentCategory = dbSelect("category","cid,classname","cid=".$category[0]["parentid"]."","",1);
		if($parentCategory)
		{
			$bigName=$parentCategory[0]["classname"];
			$bigId=$parentCategory[0]["cid"];
		}else{
			$msg = "<font color=red><b>非法操作</b></font>";
			$url = $_SERVER["HTTP_REFERER"];
			$style = "alert_error";
			$toTime = 3000;
			include "notice.php";
			exit;
		}
	
	}else{
		$msg = "<font color=red><b>非法操作</b></font>";
		$url = $_SERVER["HTTP_REFERER"];
		$style = "alert_error";
		$toTime = 3000;
		include "notice.php";
		exit;
	}

4.准备发布内容

$authorid = $_COOKIE["uid"];		//发布人ID
$title = strMagic($_POST["subject"]);		//标题
$content = strMagic($_POST["content"]);		//内容
$addtime = time();			//发表时间
$addip = ip2long($_SERVER["REMOTE_ADDR"]);//发布人IP
$classId = $_POST["classid"];		//类别ID
$rate = $_POST["price"];			//帖子售价

$n = "first, authorid, title, content, addtime, addip, classid, rate";

$v = "1, ".$authorid.", "".$title."", "".$content."", ".$addtime.", ".$addip.", ".$classId.", ".$rate."";

$result = dbInsert("details", $n, $v);
