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));

}

}
