PHP经典项目案例-（一）博客管理系统3
本篇给出首页左侧导航栏及右部公告区的实现。
六、左侧导航栏：
1、日历：
这里单独一个php文件，在显示日历的那个地方直接引用该文件即可：
cale.php
<?php class calendar{ private $year,$month,$day; private $week=array("Sun","Mon","Tue","Wed","Thu","Fri","Sat"); private $_month=array( "01"=>"一月", "02"=>"二月", "03"=>"三月", "04"=>"四月", "05"=>"五月", "06"=>"六月", "07"=>"七月", "08"=>"八月", "09"=>"九月", "10"=>"十月", "11"=>"十一月", "12"=>"十二月" ); function setyear($year){ //设置年份 $this->year=$year; } function getyear(){ //获得年份 return $this->year; } function setmonth($month){ //设置月份 $this->month=$month; } function getmonth(){ //获得月份 return $this->month; } function setday($day){ //设置日期 $this->day=$day; } function getday(){ //获得日期 return $this->day; } function OUT(){ //输出日历 $this->_env(); //设置显示的日期 $week=$this->getweek($this->year,$this->month,$this->day); //获得日期为星期几 $fweek=$this->getweek($this->year,$this->month,1); //获得此月第一天为星期几 echo "<div style="width:255;font:9pt"> <form action="%24_SERVER%5BPHP_SELF%5D" method="'post'" style="'margin:0'"> <select name="'month'" onchange="'this.form.submit();'">"; for($ttmpa=1;$ttmpamonth)==0){ $select="selected style='background-color:#FAFDE2'"; }else{ $select=""; } echo "<option value="'$ttmpb'">".$this->_month[$ttmpb]."</option>"; } echo " </select> <select name="'year'" onchange="'this.form.submit();'">"; //输出年份，前后10年 for($ctmpa=$this->year-10;$ctmpayear+10;$ctmpa++){ if($ctmpa>2050){ break; } if($ctmpayear)==0){ $select="selected style='background-color:#FAFDE2'"; }else{ $select=""; } echo "<option value="'$ctmpa'">$ctmpa</option>"; } echo "</select> </form>
<br> <table border="0" align="center">"; for($Tmpa=0;$Tmpa<count>week);$Tmpa++){ //输出星期的标头 echo "<td>".$this->week[$Tmpa]."</td>"; } for($tmpb=1;$tmpbmonth,$this->day,$this->year));$tmpb++){ //输出所有日期 if(strcmp($tmpb,$this->day)==0){ //获得当前日期，并采用特色颜色做为标记 $flag=" bgcolor='#FF3366'"; }else{ $flag=' bgcolor=#FAFDE2'; } if($tmpb==1){ echo "<tr>"; for($tmpc=0;$tmpc"; } } if(strcmp($this->getweek($this->year,$this->month,$tmpb),0)==0){ //如果是周日 echo "</tr>
<tr>
<td align="'center'">$tmpb</td>"; }else{ echo "<td align="'center'">$tmpb</td>"; } } echo "</tr></count>
</table>
</div>"; } //获得方法内指定的日期的星期数 function getweek($year,$month,$day){ $week=date("w",mktime(0,0,0,$month,$day,$year)); //获得星期 return $week; //获得星期 } function _env(){ if(isset($_POST["month"])){ $month=$_POST["month"]; }else{ $month=date("m"); //默认为本月 } if(isset($_POST["year"])){ $year=$_POST["year"]; }else{ $year=date("Y"); //默认为本年 } $this->setyear($year); $this->setmonth($month); $date=sprintf('%1d',date('d')); $this->setday($date); }} $D=new calendar; $D->OUT(); ?> 在index.php里面直接引用该文件
<!-- 日历显示 --> <tr> <span style="white-space:pre"> </span><td height="155" align="center" valign="top"><?php include 'cale.php';?></td> </tr>
2、最新文章显示：
<!-- 最新文章显示 --><tr>
<span style="white-space:pre"> </span><td height="125" align="center" valign="top"> <table width="200" border="0" cellpadding="0" cellspacing="0"> <tr> <span style="white-space:pre"> </span><td> <table width="201" border="0" cellpadding="0" cellspacing="0" style="margin-top:25px" valign="top"> </table> </td> </tr> <?php $sql="select id,title from tb_article order by id desc limit 5"; $res = $sqlHelper->execute_dql($sql); $i=1; while($info=$res->fetch_assoc()){ ?> <tr> <span style="white-space:pre"> </span><td width="201" align="left" valign="top"> <a href="article.php?file_id=<?php%20echo%20%24info%5B'id'%5D;?>" target="_blank"><font size="2"><?php echo $i."、".substr($info['title'],0,27);?></font></a> </td> </tr> <?php $i=$i+1; } ?> <tr> <td height="10" align="right"><a href="file_more.php"><img src="images/more.gif" style="max-width:90%" style="max-width:90%" border="0" alt="PHP经典项目案例-（1）博客管理系统3" > </a></td> </tr> </table> </td>
</tr>这里给出上面用到的方法实现代码：
sqlHelper.class.php部分代码：
class SqlHelper{ public $mysqli; public $dbname="db_tmlog"; public $username="root"; public $password="root"; public $host="localhost"; public function __construct(){ $this->mysqli = new mysqli($this->host, $this->username, $this->password, $this->dbname); if($this->mysqli->connect_error){ die("连接失败".$this->mysqli->connect_error); } $this->mysqli->query("set names utf8"); } //执行dql语句 public function execute_dql($sql){ $res = $this->mysqli->query($sql) or die($this->mysqli->error); //这里返回的是一个结果集，当调用$row = $res->fetch_assoc()时是一条一条的向下走，应该使用while循环 return $res; } <span style="font-family: Arial, Helvetica, sans-serif;">}</span>在使用数据库查询之前，先把这个文件包进去，然后new一个工具类对象，然后使用对象调用里面的函数。
3、最新图片显示
<!-- 最新图片显示 --><tr>
<span style="white-space:pre"> </span><td height="201" align="center" valign="top">
<br> <table width="145" border="0" cellspacing="0" cellpadding="0"> <tr> <span style="white-space:pre"> </span><td> <table width="201" border="0" cellspacing="0" cellpadding="0" valign="top" style="margin-top:5px;"> <?php <span style="white-space:pre"> $sql="select id,tpmc,file from tb_tpsc order by id desc limit 2"; $res2 = $sqlHelper->execute_dql($sql); while($info=$res2->fetch_assoc()){ <span style="white-space:pre"> </span>$query="select * from tb_tpsc where id=".$info['id']; <span style="white-space:pre"> </span>$result=$sqlHelper->execute_dql($query); <span style="white-space:pre"> </span>if($row = $result->fetch_assoc()){ <span style="white-space:pre"> </span>$data = $row['file']; <span style="white-space:pre"> </span>} ?> <tr> <span style="white-space:pre"> </span><td width="9" rowspan="2" align="center"> </td> <td width="147" align="center"> <a href="image.php?recid=<?php%20echo%20%24info%5B'id'%5D;%20?>" target="_blank"> <img src="<?php%20echo%20%24data;?>" style="max-width:90%" style="max-width:90%" border="0" alt="PHP经典项目案例-（1）博客管理系统3" > </a> </td> <td width="10" rowspan="2" align="center"> </td> </tr> <tr> <td align="center">图片名称：<?php echo $info['tpmc'];?>
</td> </tr> <?php } ?> <tr> <span style="white-space:pre"> </span><td colspan="3" height="10" align="right"><a href="pic_more.php"><img src="images/more.gif" style="max-width:90%" style="max-width:90%" border="0" alt="PHP经典项目案例-（1）博客管理系统3" > </a></td> </tr> </table> </td> </tr> </table> </td>
</tr>4、公告区实现
在公告区使用了我以前没有见过的一个标签
它里面设置了一些属性，就是当鼠标停留在上面的时候它就停止滚动，离开的时候就开始滚动。
<?php <span style="white-space:pre"> $p_sql = "select * from tb_public order by id desc"; $p_rst = $sqlHelper->execute_dql($p_sql);?><marquee onmouseover="this.stop()" style="width:426px; height:280px" onmouseout="this.start()" scrollamount="2" scrolldelay="7" direction="up" align=""><span style="FONT-SIZE: 9pt"><center>
<?php <span style="white-space:pre"> </center></span>while($p_row = $p_rst->fetch_row()){?><a href="#" onclick="wopen=open('show_pub.php?id=<?php echo $p_row[0]; ?>','','height=200,width=1000,scollbars=no')"><?php echo $p_row[1]; ?></a><br> <?php }?></marquee>到这里我们的首页基本就实现了。这是index.php 的完整代码：index.php提取码：iu09
