主要改修的还是ajax部分，由于前面写的是基于mvc的后台所以前端部分会有点修改。以下是php后台代码
这一部分说实话弄了我半天，主要是一个去重复的功能，json对象这部分，后面会提到
增加数据
add.pp:
<?php
header("Content-type:text/html;charset=utf8");
$conne = mysql_connect("localhost","root","root")or die("链接失败"[email protected]_error());
$select = mysql_select_db("test",$conne)or die("链接失败"[email protected]_error());
$utfgbk = mysql_query("set names utf8");
$title = $_REQUEST[‘title‘];
$body = $_REQUEST[‘body‘];
$arraysone = array(‘one‘=>‘ture‘,‘two‘=>‘false‘);
$arrays = array(array(‘one‘=>‘ture‘,‘two‘=>‘false‘));
$row =mysql_query("select count(*) from article where title=‘$title‘");
$text = mysql_fetch_row($row);
$nam = $text[0];
if($nam==1){
echo json_encode(array("eger"=>$arraysone[‘two‘]));
}else{
$sql = mysql_query("insert into article(title,body)values(‘$title‘,‘$body‘)");
echo json_encode($arrays[0][‘one‘]);
}
?>
有些数据库连接操作我并没有弄到一个文件去，而且增删改查文件都是独立的，
删除部分
remove.php <?php
header("content-type:text/html;charset=utf8");
$conne = mysql_connect("localhost","root","root")or die("数据库用户名或密码错误"[email protected]_error);
$select = mysql_select_db("test",$conne)or die("连接失败"[email protected]_error);
$utf = mysql_query("set names uthf8");
$id = $_REQUEST[‘textid‘];
if($id){
mysql_query("delete from article where id=$id");
}else{
echo "false";
}
?>
修改部分
update.php <?php
header("content-type:text/html;charset=utf8");
$conne =mysql_connect("localhost","root","root")or die("数据库用户名或密码错误"[email protected]_error());
$select = mysql_select_db("test",$conne)or die("数据库连接失败"[email protected]_error());
$utf = mysql_query("set names utf8");
$id = $_REQUEST[‘textid‘];
$title = $_REQUEST[‘title‘];
$body = $_REQUEST[‘bodyval‘];
$sql=mysql_query("update article set title=‘$title‘,body=‘$body‘ where id=$id");
mysql_free_result($sql);
?>
查询部分，查询部分我是分开来的，一个是搜索，一个是列出所有内容并分页显示，分页功能写在前端代码部分
这是搜索的后台代码部分
search.php
<?php
header("content-type:text/html;charset=utf8");
$conne =mysql_connect("localhost","root","root")or die("数据库用户名或密码错误"[email protected]_error());
$select = mysql_select_db("test",$conne)or die("数据库连接失败"[email protected]_error());
$utf = mysql_query("set names utf8");
$arrays = array();
$i=0;
$key = $_REQUEST[‘keys‘];
if($key){
$result = mysql_query("select*from article where title like‘%$key%‘ or body like ‘%$key%‘");
while($row = mysql_fetch_array($result,MYSQL_ASSOC)){
$arrays[$i]=$row;
$i++;
}
echo json_encode(array("datalist"=>$arrays));
}else{
$result = mysql_query("select*from article");
while($row = mysql_fetch_array($result,MYSQL_ASSOC)){
$arrays[$i]=$row;
$i++;
}
echo json_encode(array("datalist"=>$arrays));
}
?>
这是查询翻页部分，其实这部分删除和修改及搜索都有用到，所以这是通用的一部分
<?php
header("Content-type:text/html;charset=utf8");
$conne = mysql_connect("localhost","root","root")or die("数据库用户名或密码错误"[email protected]_error()) ;
mysql_select_db("test", $conne)or die("数据库连接失败"[email protected]_error());
mysql_query("set names utf8");
$listsql = mysql_query("select*from article");
$arrays = array();
$i=0;
while($row = mysql_fetch_array($listsql,MYSQL_ASSOC)){
$arrays[$i]=$row;
$i++;
}
echo json_encode(array(‘datalist‘=>$arrays));
?>
