get方法!
post方法需要改动一下
<body> <?php $name=""; $fytj=""; if(!empty($_POST["name"]))//多判断一次post { $name=$_POST["name"]; $fytj="name='{$name}'";//加一个条件 } if(!empty($_GET["name"])) { $name=$_GET["name"]; } $tj=" where AreaName like '%{$name}%' "; ?> <div> <form action="0512am-query.php" method="post">//method改为post 请输入名称：<input type="text" name="name" value="<?php echo $name;?>" /> <input type="submit" value="查询" /> </form> </div><br /> <table width="100%" border="1" cellpadding="0" cellspacing="0"> <tr> <td>区域代号</td> <td>名称</td> <td>父级区域代号</td> </tr> <?php include("ChaXun.class.php"); $db=new ChaXun(); $sqlall="select count(*) from chinastates".$tj; $attrall=$db->Query($sqlall); $total=$attrall[0][0]; include("page.class.php"); $page=new Page($total,20); $sql="select * from chinastates ".$tj.$page->limit; $attr=$db->Query($sql); foreach($attr as $v) { echo"<tr> <td>{$v[0]}</td> <td>{$v[1]}</td> <td>{$v[2]}</td> </tr>"; } ?> </table> <div> <?php echo $page->fpage(); ?> </div> </body>
