PHP、AJAX综合练习（增、删、改、查、分页、模糊查询）
先来几张效果图
主页面分页显示：
关键字查询，关键字描红
添加数组，弹出窗口，点击保存，再不刷新页面的同时添加到网页数据
修改界面：弹出窗口，文本框中保留点击的车辆的原始信息

几个处理页面代码
1.关键字查询和分页 chuli.php
<?php include("DBDA.class.php"); $db=new DBDA(); $aa=$_POST["aa"]; $page = $_POST["page"]; $num = 10; $tiao = ($page-1)*$num; $tj=""; if(!empty($aa)) { $tj=" name like '%{$aa}%' "; }else { $tj=" 1=1 "; } $sql="select * from car where ".$tj." limit {$tiao},{$num}"; $attr=$db->StrQuery($sql); $attr1=str_replace($aa, "<span style='color:red'>{$aa}</span>", $attr); echo $attr1; ?>
2.计算数据总条数 zongshu.php
<?php include("DBDA.class.php"); $db = new DBDA(); $aa = $_POST["aa"]; $num = 10; $sql = "select count(*) from car where name like '%{$aa}%'"; $zts = $db->StrQuery($sql); echo ceil($zts/$num); ?>
3.把汽车表中的brand行改名字 chuli1.php
<?php include("DBDA.class.php"); $db=new DBDA(); $bb=$_POST["bb"]; $sql="select brand_name from brand where brand_code='{$bb}'"; $atr=$db->StrQuery($sql); echo $atr; ?>
3.删除处理页面 shanchu.php
<?php include("DBDA.class.php"); $db=new DBDA(); $bs=$_POST["bs"]; $sql="delete from car where code='{$bs}'"; if($db->query($sql,0)) { echo "ok"; }else { echo "no"; } ?>
4.添加处理界面 tianjia.php
<?php include("DBDA.class.php"); $db=new DBDA(); $xinghao=$_POST["xinghao1"]; $cheming=$_POST["cheming1"]; $riqi=$_POST["riqi1"]; $youhao=$_POST["youhao1"]; $dongli=$_POST["dongli1"]; $pailiang=$_POST["pailiang1"]; $jiage=$_POST["jiage1"]; $sql="insert into car values('b001','{$xinghao}','{$cheming}','{$riqi}','{$youhao}','{$dongli}','{$pailiang}','{$jiage}','');"; if($db->Query($sql,0)) { echo "111"; }else { echo "222"; } ?>
5.修改前给弹出框中文本框添加原始内容 xiugai.php
<?php include("DBDA.class.php"); $db=new DBDA(); $xg=$_POST["xg"]; $sql="select * from car where code='{$xg}'"; echo $db->StrQuery($sql); ?>
6.修改后处理页面 xiugaihou.php
<?php $code=$_POST["code"]; $xinghao=$_POST["xinghao"]; $cheming=$_POST["cheming"]; $riqi=$_POST["riqi"]; $youhao=$_POST["youhao"]; $dongli=$_POST["dongli"]; $pailiang=$_POST["pailiang"]; $jiage=$_POST["jiage"]; include("DBDA.class.php"); $db=new DBDA(); $sql="update car set name='{$xinghao}',brand='{$cheming}',time='{$riqi}',oil='{$youhao}',powers='{$dongli}',exhaust='{$pailiang}',price='{$jiage}' where code='{$code}'"; if($db->query($sql,0)) { echo "111"; }else { echo "222"; } ?>
