PHP开发文章发布系统之前台文章详情页

前台文章详情页大致布局如下

前台文章详情页主要是根据列表页传递过来的id,查询数据库,取出id对应文章的详细信息,流程图如下:

代码如下:

<?php
require_once("../paging.php");
//根据传递过来的id值,获取详情页内容,存于数组$data中
$id=$_GET['id'];
$SQL="SELECT * FROM article WHERE id=$id";
$info=mysqli_query($conn,$SQL);
$a=mysqli_num_rows($info);
if($info&&mysqli_num_rows($info)){
	while($row=mysqli_fetch_assoc($info)){
		$data[]=$row;
	}
}else{
	$data=array();
}
//取最新添加的6条编号、标题信息,存于数组$data_title
if($info_title&&mysqli_num_rows($info_title)){
	while($row_title=mysqli_fetch_assoc($info_title)){
		$data_title[]=$row_title;
	}
}else{
	$data_title=array();
}
?>

代码注释:

  • 加入的php代码主要是通过id,将数据库里面的内容循环显示出来程序部分的注释很清楚,大家可以复制到本地自己测试
