php多功能搜索+加分页 代码简单，精简
- 静态页面
<input type="search" placeholder="模糊搜索" name="search" value="<?php echo empty($_GET['search'])?'':$_GET['search'];?>"/>
</form>
<form action="fenye.php" method="get">
<button name="yes" value="是" >我的客户(是)</button>
<button name="no" value="否">停用客户(否)</button>
<button name="my" value="管理员 元程浩" >我的客户</button>
</form>

接收值
//提示Notice:Undefined varialbe:tmp_i //在程序开头加一句 error_reporting(E_ALL ^ E_NOTICE); $dbhost = 'localhost:3306'; $dbuser = 'root'; $dbpass = '密码'; $conn = mysqli_connect($dbhost, $dbuser, $dbpass); mysqli_query($conn , "set names utf8"); mysqli_select_db( $conn, '数据库' ); $pagesize=2; $p=isset($_GET['p'])?$_GET['p']:1;//当前页数，默认为1 $offset = ($p-1)*$pagesize; @$search=$_GET['search']; @$yes=$_GET['yes']; @$no=$_GET['no']; @$my=$_GET['my']; -
判断
if(!empty($search)){ $query[]="name LIKE '%$search%' or type LIKE '%$search%' or company LIKE '%$search%' or telephone LIKE '%$search%' or star LIKE '%$search%' or number LIKE '%$search%' or money LIKE '%$search%' or collection LIKE '%$search%'"; $urllist[]="search=".$_GET['search']; } if($yes){ $query[]="star like '%$yes%'"; $urllist[]="yes=".$_GET['yes']; } if($no){ $query[]="star like '%$no%'"; $urllist[]="no=".$_GET['no']; } if($my){ $query[]="person like '%$my%'"; $urllist[]="my=".$_GET['my']; } -
查寻的信息输出
if(count($query)>0){ $where=" where ".implode(" and ",$query); $url='&'.implode('&',$urllist); } -
分页
$abs = "select count(*) nums FROM message $where"; $count_result = mysqli_query($conn,$abs); $count_array = mysqli_fetch_array($count_result); $pagenum=ceil($count_array['nums']/$pagesize); echo '<p>' , '总记录数：', $count_array['nums'] , '，', '显示  ' , $offset+1 , '~' , $offset+$pagesize , '</p>'; $prepage=$p-1; if($p==1){ $prepage=1; } $nextpage=$p+1; if($p==$pagenum){ $nextpage=$pagenum; } if ($pagenum > 1) { echo " <a href='fenye.php?p=1{$url}'>首页</a>"; // 第一页 echo "<a href='fenye.php?p={$prepage}{$url}'>上一页</a>"; for($i=1;$i<=$pagenum;$i++) { if($i==$p) { echo ' [',$i,']'; } else { echo " <a href='fenye.php?p=$i{$url}'> $i </a>"; } } echo "<a href='fenye.php?p={$nextpage}{$url}'>下一页</a>"; echo "<a href='fenye.php?p=$pagenum{$url}'>尾页</a>"; // 最后一页 } mysqli_close($conn); -
