有了前面的基础，后面就是将页面展示出来。
预览图如下：1号和31号分别有活动，会一并显示出来
这里需要搞定几个问题，一个就是数据库的连接，我们用\sys\class\class.db_connect.inc.php
<?php
/*
* 数据库操作（数据库访问，认证等）
*/
class DB_Connect
{
/**
* Stores a database object
*
* @var object A database object
*/
protected $db;
/**
* Checks for a DB object or creates one if one isn't found
*
* @param object $dbo A database object
*/
protected function __construct($db = NULL)
{
if (is_object($db)) {
$this->db = $db;
} else {
// Constants are defined in /sys/config/db-cred.inc.php
$dsn = "mysql:host=" . DB_HOST . ";dbname=" . DB_NAME;
try {
$this->db = new PDO($dsn, DB_USER, DB_PASS, array(PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES ' . DB_ENCODE));
} catch (Exception $e) {
// If the DB connection fails, output the error
die ($e->getMessage());
}
}
}
}
?>
程序中需要引入DB_USER等的定义文件：db-cred.inc.php
<?php
/*
* Created on 2012-4-24 by xiongxuebing
*/
/*
* Create an empty array to store constants
*/
$C = array();
/*
* The database host URL
*/
$C['DB_HOST'] = 'localhost';
/*
* The database username
*/
$C['DB_USER'] = 'root';
/*
* The database password
*/
$C['DB_PASS'] = 'root';
/*
* The name of the database to work with
*/
$C['DB_NAME'] = 'php-jquery_example';
$C['DB_ENCODE'] = 'UTF8';
?>
需要注意的是,类似DB_HOST的常量并没有直接定义，而是通过在/sys/core/init.inc.php中进行定义：
foreach ($C as $name => $val) {
define($name, $val);
}
原文件如下的示：
<?php
/*
* Created on 2016-6-19 by luhx
*/
session_start();
/*
* Generate an anti-CSRF token if one doesn't exist
*/
if (!isset($_SESSION['token'])) {
$_SESSION['token'] = sha1(uniqid(mt_rand(), TRUE));
}
/*
* Include the necessary configuration info
*/
include_once '../sys/config/db-cred.inc.php';
/*
* Define constants for configuration info
*/
foreach ($C as $name => $val) {
define($name, $val);
}
/*
* Create a PDO object
*/
$dsn = "mysql:host=" . DB_HOST . ";dbname=" . DB_NAME;
$dbo = new PDO($dsn, DB_USER, DB_PASS);
/*
* Define the auto-load function for classes
*/
function __autoload($class)
{
$filename = "../sys/class/class." . $class . ".inc.php";
if (file_exists($filename)) {
include_once $filename;
}
}
?>
接下来需显示日历:index.php
<?php
/*
* Created on 2012-4-24 by xiongxuebing
*/
/*
* 包含必须的文件
*/
include_once '../sys/core/init.inc.php';
/*
* 载入日历
*/
$cal = new Calendar($dbo, "2010-01-01 12:00:00");
/**
* 初始化标题和样式文件
*/
$page_title = "Events Calendar";
$css_files = array('style.css');
include_once 'assets/common/header.inc.php';
?>
<?php
/*
* 包含尾页
*/
include_once 'assets/common/footer.inc.php';
?>
首先需要创建一个Calendar
/sys/class/class.calendar.inc.php
<?php
/*
* Created on 2012-4-24 by xiongxuebing
*/
class Calendar extends DB_Connect
{
/**
* 日历根据此日期构建
* YYYY-MM-DD HH:MM:SS
* @var string
*/
private $_useDate;
/**
* 日历显示月份
* @var int
*/
private $_m;
/**
* 年
* @var int
*/
private $_y;
/**
* 这个月有多少天
* @var int
*/
private $_daysInMonth;
/**
* 这个月从周几开始
* @var int
*/
private $_startDay;
public function __construct($dbo = NULL, $useDate = NULL)
{
parent::__construct($dbo);
/*
* Gather and store data relevant to the month
*/
if (isset($useDate)) {
$this->_useDate = $useDate;
} else {
$this->_useDate = date('Y-m-d H:i:s');
}
$ts = strtotime($this->_useDate);
$this->_m = date('m', $ts);
$this->_y = date('Y', $ts);
$this->_daysInMonth = cal_days_in_month(
CAL_GREGORIAN,
$this->_m,
$this->_y
);
$ts = mktime(0, 0, 0, $this->_m, 1, $this->_y);
$this->_startDay = date('w', $ts);
}
/**
