调去页
<?php   require_once("SubPages.php");   //每页显示的条数     $page_size=20;   //总条目数     $nums=1024;   //每次显示的页数     $sub_pages=10;   //得到当前是第几页     $pageCurrent=$_GET["p"];     //if(!$pageCurrent) $pageCurrent=1;           $subPages=new SubPages($page_size,$nums,$pageCurrent,$sub_pages,"test.php?p=",2);   ?>

我这样用完后点击不跳转....

页面应该有跳转的,然后你还要在sql里面设置limit $offset,$pagesize

你这都出来了,你看下url 调试调试

这个是URL 就是不跳...

麻烦你说详细点,没找到你说的设置limit $offset,$pagesize

你的这个类仅仅是用于产生分页条的
你还需要自己去控制数据库查询

应该没起作用吧

你的这个类仅仅是用于产生分页条的
你还需要自己去控制数据库查询 版主已经说的很清楚了

$p=$_GET[p]?$_GET[p]:1;$offset=($p-1)*$pagesize;$query=mysql_query("select * from sometable limit $offset,$pagesize);while($rs=mysql_fetch_array($query)){  //code }

Copy after login

按照你说的我现在这样做了,
<?php 	include("../conn/conn.php");	require_once("../class/SubPages.php");	$p=$_GET[p]?$_GET[p]:1;	$offset=($p-1)*$pagesize;	$page_size=15;														//每页显示的条数	$nums = 1024;														//一共有多少页	$sub_pages=10;														//显示多少个分页	$pageCurrent=$_GET["p"];											//当前得到的是第几页	$query = "select * from tbl_apply_register limit $offset,$page_size";	$info = mysql_query($query);	?>
Copy after login

下面是循环取得数据
<?php while ($row = mysql_fetch_array($info)){ ?>    <tbody>    	<tr>        <td><input name="flags[]" type="checkbox" value="<?php echo $row[ID];?>" /></td>        <td><?php echo $row[name];?></td>        <td><?php echo $row[position];?></td>        <td><?php echo $row[department];?></td>        <td><?php echo $row[configinfo];?></td>        <td><?php echo $row[number];?></td>        <td><?php echo $row[type];?></td>        <td><?php echo $row[date];?></td>        <td><?php echo $row[note];?></td>        <td><a href="upadte_out.php?ID=<?php echo $row[ID];?>"><img  src="/static/imghw/default1.png"  data-src="../images/edit.gif"  class="lazy"   / alt="有这么一个分页类,怎么才能让他工作起来." ></a>  <a href="del_out_ok.php?ID=<?php echo $row[ID];?>" onclick="javascript:del_sure( )"><img  src="/static/imghw/default1.png"  data-src="../images/del.gif"  class="lazy"   / alt="有这么一个分页类,怎么才能让他工作起来." ></a></td>        </tr>    </tbody>     <?php }?> 	
Copy after login


这个是调用分页
<?php $subPages=new SubPages($page_size,$nums,$pageCurrent,$sub_pages,"show_user.php?p=",2);?>
Copy after login

现在是每页显示多少条数据都可以控制了,可就是点击分页后是出现找不到网页...
麻烦您帮我指点指点..

你的这些代码是在 show_user.php 中的吗?

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,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

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.

Explain late static binding in PHP (static::). Explain late static binding in PHP (static::). Apr 03, 2025 am 12:04 AM

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
