想在分页上加首页和尾页

内容发错了,下边应该是分页的内容,想加个首页和尾页

<?php    $pages=ceil($count/$list_num);       echo "<table width=740 border=0 cellspacing=0 cellpadding=0 align=center class='text'>          <tbody>           <tr>      <td width='190'><font color='#ff0000'>目前共有".$count."条记录</font> </td>    <td width='205'>共".$pages."页</td>";	if($offset){	   $preoffset=$offset-$list_num;	print "<td width='170'><a href=\"?offset=$preoffset\">上一页</a></td>";}	else {	  echo "<td width='170'>上一页</td>";	}	   $newoffset=$offset+$list_num;		if(($pages!=0)&&(($newoffset/$list_num)!=$pages))	{	 print("<td width='170'><a  href=\"?offset=$newoffset\">下一页</a></td>");	}	 else{ echo "<td width='170'>下一页</td>";}	    $pageno=($offset/$list_num)+1;	echo "<td width='112' class=text>第<input class=text type='text' size='4'value=".$pageno." readonly>页</td>	      <td width='4'> </td></tr></table>"; ?>     
Copy after login

print "首页上一页";}

print("下一页尾页");

居然两个print语句的写法不一样……唉,进步空间很大

print "首页上一页";}

print("下一页尾页");

居然两个print语句的写法不一样……唉,进步空间很大 关于尾页的问题我还想问一下,加入我的列表有6也,我加入了尾页的语句后,点“尾页”后,系统没有显示第6页的内容,而是只显示了一个列表头,并且在第()页处显示的是第(6.666667)页,这是怎么回事呢?

你的总页数也就是你的尾页数
你这里的总页数是$pages,那么尾页数也是$pages
你这个应该要计算要清楚,如果有小数点的要+1的
$pages=ceil($count/$list_num); 这里这个总页数是正确的,不过要判断一下$list_num不能为0哦

$pages=ceil($count/$list_num); 这里这个总页数是正确的,不过要判断一下$list_num不能为0哦 不好意思我是个菜鸟,所以想加问一句,我这个$list_num是之前定义过等于30的,为什么还要判断不能为0呢?还有就是那我的尾页语句应该怎么写?如果我写成>尾页的话,它就跳到第(1.2)页了

有定义了就好,只是你怎么会计算出小数了呢?ceil这个可是取整数的啊

$pageno=($offset/$list_num)+1;
你这个干吗还要算一次呢?
你那个文本框里默认的不应该是当前页么?就算不是当前页,这里不应该重新算吧?就算要重新算,你也要取整数啊

php页面首部出现一大段注释说明,怎么找到是哪写的,
注释的内容,如下:
* @copyright :Copyright 2006 feifengxlq * @license:version 2.0 * @create:2006-5-31 * @modify:2006-6-1 * @modify:feifengxlq 2006-11-4 * description:超强分页类,四种分页模式,默认采用类似baidu,google的分页风格。 * 2.0增加功能:支持自定义风格,自定义样式,同时支持PHP4和。。。。。。。

$pageno=($offset/$list_num)+1;
你这个干吗还要算一次呢?
你那个文本框里默认的不应该是当前页么?就算不是当前页,这里不应该重新算吧?就算要重新算,你也要取整数啊 那是不是我应该把这句去掉?

$pageno=($offset/$list_num)+1;
Copy after login
然后把第$pageno页改成第$pages页?

$pageno=floor(($offset/$list_num)+1);  //改成这样呢

$pageno=floor(($offset/$list_num)+1);  //改成这样呢 嗯,跳到最后一页了,但是最后一页只显示列表的头

$pageno = ceil($offset/$list_num);

ceil 取得 大于等于 $offset/$list_num 的最小整数

$pageno = ceil($offset/$list_num);

ceil 取得 大于等于 $offset/$list_num 的最小整数 嗯,问题是这样的话,第1页显示的是第0页,我还是直接不要尾页这个功能了吧

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
