discuz 如何添加数据DB::insert和更新数据DB::update 查询DB::qu

• 1.添加数据DB::insert
• $uid=empty($_POST[‘uid’]) ? “” : $_POST[‘uid’];
• $username=empty($_POST[‘username’]) ? “” : $_POST[‘username’];
• $display_type=empty($_POST[‘display_type’]) ? “” : $_POST[‘display_type’];
• $filename=empty($_POST[‘filename’]) ? “” : $_POST[‘filename’];
• $details=empty($_POST[‘details’]) ? “” : $_POST[‘details’];
• $videoname=empty($_POST[‘videoname’]) ? “” : $_POST[‘videoname’];
• //$sql=”insert into pre_home_video(uid,display_type,filename,default) values(‘$uid’,’$display_type’,’$filename’,’$default’)”;
• //$query = DB::query($sql);
• if(!empty($_POST[‘uid’]) && !empty($_POST[‘display_type’]) && !empty($_POST[‘display_type’] ))
• {
• $count = DB::result(DB::query(“select uid from pre_common_member where uid= $uid”), 0);
• if($count)
• {
• $arr=array();
• $arr[‘uid’] = $uid;
• $arr[‘username’] = $username;
• $arr[‘display_type’] = $display_type;
• $arr[‘filename’] = $filename;
• $arr[‘details’] = $details;
• $arr[‘videoname’] = $videoname;
• if(!file_exists(“data/video/{$uid}”)){
• mkdir(“data/video/{$uid}”, 0700);
• }
• if(!file_exists(“data/video/{$uid}/cover”)){
• mkdir(“data/video/{$uid}/cover”, 0700);
• }
• $count1=DB::insert(‘home_video’,$arr);
• if($count1)
• {
• echo(“<script type=’text/javascript’>alert(‘添加成功’);window.location = \”admin.php?action=video\”;</script>”);
• }
• }
• else
• {
• echo(“<script type=’text/javascript’>alert(‘添加失败，该用户不存在’);</script>”);
• }
• 更新
• $id = $_GET[‘id’] ? $_GET[‘id’] : 0;
• $query = DB::query(“select * from “.DB::table(‘home_hall’).” where id=$id”);
• if($query){
• $data = DB::fetch($query);
• if($type == ‘gold’){
• if($op == ‘add’){
• $data[‘isgold’] = 1;
• }elseif($op = ‘cancle’){
• $data[‘isgold’] = 0;
• }
• DB::update(‘home_hall’, array(‘isgold’=>$data[‘isgold’]),array(‘id’=> $id));
• }elseif($type == ‘index’){
• if($op == ‘add’){
• $data[‘isindex’] = 1;
• }elseif($op = ‘cancle’){
• $data[‘isindex’] = 0;
• }
• DB::update(‘home_hall’, array(‘isindex’=>$data[‘isindex’]),array(‘id’=> $id));
• }
• }else{
• echo ‘没有此展厅’;
• }
• 3.查询，返回结果集
• $perpage = 25;
• $start = ($page-1)*$perpage;
• $mpurl = ADMINSCRIPT.’?action=goldhall’;
• $count = DB::result(DB::query(“SELECT COUNT(*) FROM “.DB::table(‘home_hall’)), 0);
• if($count){
• $query = DB::query(“SELECT * FROM “.DB::table(‘home_hall’).” limit $start, $perpage”);
• while ($value = DB::fetch($query)) {
• $list[] = $value;
• }
• $multipage = multi($count, $perpage, $page, $mpurl);
• }
• echo ‘<table width=”100%” border=1>’;
• echo ‘<tr><td>用户id</td><td>展厅名</td><td>展厅级别</td><td>联系电话</td><td>操作</td><td>操作</td></tr>’;
• foreach ($list as $k => $v){
• echo “<tr>”;
• echo “<td>{$v[‘uid’]}</td>”;
• echo “<td>{$v[‘hallname’]}</td>”;
• echo $v[‘isgold’] ? “<td>金牌</td>” : “<td>普通</td>”;
• echo “<td>{$v[‘telephone’]}</td>”;
• if($v[‘isgold’] == 1){
• echo “<td><a href=’admin.php?action=goldhall&id={$v[‘id’]}&type=gold&op=cancle’>取消金牌展厅</a></td>”;
• }else{
• echo “<td><a href=’admin.php?action=goldhall&id={$v[‘id’]}&type=gold&op=add’>升级</a></td>”;
• }
• if($v[‘isindex’] == 1){
• echo “<td><a href=’admin.php?action=goldhall&id={$v[‘id’]}&type=index&op=cancle’>取消首页推荐</a></td>”;
• }else{
• echo “<td><a href=’admin.php?action=goldhall&id={$v[‘id’]}&type=index&op=add’>首页推荐</a></td>”;
• }
• echo “</tr>”;
• }
• echo ‘</table>’;
• if($multipage){
• echo $multipage;
• }
• //删除
• if($_GET[‘op’] == ‘delete’){
• if($gid){ //还要删除文件
• DB::delete(‘saige_geku’, array(‘id’ => $gid));
• DB::delete(‘saige_gekufield’, array(‘gid’ => $gid));
• DB::delete(‘saige_gkcomment’, array(‘gid’ => $gid));
• }
• }
