public function json_product_list($where, $order){ global $_m; $this->table...
public function json_product_list($where, $order){
 global $_m;
 $this->table = load::sys_class('tabledata', 'new');
 $p = $_m['table']['product'];
 $s = $_m['table']['shopv2_product'];
 if($_m['config']['shopv2_open']){//开启在线订购时
  $table = $p.' left join '.$s." on ({$p}.id = {$s}.pid)";
  $where = "{$p}.lang='{$_m['lang']}' and ({$p}.recycle = '0' or {$p}.recycle = '-1') {$where}";
 }else{
  $table = $p;
  $where = "lang='{$_m['lang']}' and (recycle = '0' or recycle = '-1') {$where}";
 }
 $data = $this->table->getdata($table, '*', $where, $order);
 foreach($data as $key=>$val){
  if(!$val['pid'])$data[$key]['pid'] = $val['id'];
 }
 return $data;
 }

例子一:

                    $u = $_m['table']['user'];
                    $o = $_m['table']['shopv2_order'];
                    $d = $u.' left join '.$o." on {$u}.id = {$o}.uid";

  function dotable_course_user_list_json(){
   global $_m;
    $id=$_m[form]['id'];//教师模块id
    $tid=$_m[form]['tid'];//教师登录用户id
    $tn=$_m[form]['tn'];//教师用户名
     $term1  = $_m[form]['search_title'];  //获取搜索关键词
    $search1 = $term1  ?"and username like '%{$term1}%' ":'';//增加查询报名表编号
    $table = load::sys_class('tabledata', 'new');
    //$where = "lang='cn' {$search} {$search1}"; //在条件语句中加入查询条件 $search
   $u = $_m['table']['user'];
   $o = $_m['table']['shopv2_order'];
   $d = $u.' left join '.$o." on {$u}.id = {$o}.uid";
    //$table = $u.' left join '.$a." on (find_in_set(u.id,a.user_id) != 0)";
   $where = "{$u}.lang='{$_m['lang']}'";
    $order = "{$u}.id desc";
    $array = $table->getdata($d, '*', $where, $order);
    //$data = $this->table->getdata($table, '*', $where, $order)
    //$time=date('y-m-d h:i:s',time());
    foreach($array as $key => $val){
    //会员组
    $rs_user_group=db::get_one("select id,name from ".$_m['table']['user_group']." where id='$val[groupid]' ");
    //状态
     //班型
    //$rs1=db::get_all("select s.class_id,a.user_id,a.id,a.number,cc.classhour from ".$_m['table']['my_application']." as a inner join ".$_m['table']['my_application_subject']." as s on a.number=s.number inner join ".$_m['table']['my_class']." as c on s.class_id=c.id inner join ".$_m['table']['my_class_course']." as cc on cc.class_id=c.id where s.class_id<>0 and s.type_11=0 and c.teachers_id='$val[id]' and cc.endtime>'$time'");
    $list = array();
    $list[] = "{$val['username']}";
    $list[] = "{$rs_user_group['name']}";
    $list[] = "";
    $list[] = "";
    $list[] = "";
    $list[] = "";
    $list[] = "";
    $list[] = "";
    $list[] = "";
    $list[] = "<a class='btn btn-danger view_error' lay-id='{$val['id']}' href='javascript:;'><i class='glyphicon glyphicon-edit'></i> 错题集</a>";
    $list[] = "";
    $list[] = "";
    $rarray[] = $list;
    }
   // dump($rarray);
   $table->rdata($rarray);//返回数据
  }

例子二:join find_in_set

                    $u = $_m['table']['user'];
                    $a = $_m['table']['my_application'];
                    $d = $u.' left join '.$a." on find_in_set({$u}.id,{$a}.user_id) != 0";

  function dotable_course_user_list_json(){
   global $_m;
    $id=$_m[form]['id'];//教师模块id
    $tid=$_m[form]['tid'];//教师登录用户id
    $tn=$_m[form]['tn'];//教师用户名
     $term1  = $_m[form]['search_title'];  //获取搜索关键词
    $search1 = $term1  ?"and username like '%{$term1}%' ":'';//增加查询报名表编号
    $table = load::sys_class('tabledata', 'new');
    //$where = "lang='cn' {$search} {$search1}"; //在条件语句中加入查询条件 $search
   $u = $_m['table']['user'];
   //$o = $_m['table']['shopv2_order'];
   $a = $_m['table']['my_application'];
   //$d = $u.' left join '.$o." on {$u}.id = {$o}.uid";
   $d = $u.' left join '.$a." on find_in_set({$u}.id,{$a}.user_id) != 0";
   $where = "{$u}.lang='{$_m['lang']}'";
    $order = "{$u}.id desc";
    $array = $table->getdata($d, '*', $where, $order);
    //$data = $this->table->getdata($table, '*', $where, $order)
    //$time=date('y-m-d h:i:s',time());
    foreach($array as $key => $val){
    //会员组
    $rs_user_group=db::get_one("select id,name from ".$_m['table']['user_group']." where id='$val[groupid]' ");
    //状态
     //班型
    //$rs1=db::get_all("select s.class_id,a.user_id,a.id,a.number,cc.classhour from ".$_m['table']['my_application']." as a inner join ".$_m['table']['my_application_subject']." as s on a.number=s.number inner join ".$_m['table']['my_class']." as c on s.class_id=c.id inner join ".$_m['table']['my_class_course']." as cc on cc.class_id=c.id where s.class_id<>0 and s.type_11=0 and c.teachers_id='$val[id]' and cc.endtime>'$time'");
    $list = array();
    $list[] = "{$val['username']}";
    $list[] = "{$rs_user_group['name']}";
    $list[] = "";
    $list[] = "";
    $list[] = "";
    $list[] = "";
    $list[] = "";
    $list[] = "";
    $list[] = "";
    $list[] = "<a class='btn btn-danger view_error' lay-id='{$val['id']}' href='javascript:;'><i class='glyphicon glyphicon-edit'></i> 错题集</a>";
    $list[] = "";
    $list[] = "";
    $rarray[] = $list;
    }
   // dump($rarray);
   $table->rdata($rarray);//返回数据
  }

注意:

1、列出全部数据

$data = $this->table->getdata($table, '*', $where, $order)

2、只列出指定字段数据

$array = $table->getdata($d, "{$u}.username,{$u}.groupid", $where, $order);

3、模糊查询

$where = "{$u}.lang='{$_m['lang']}' and {$u}.username like '%{$term1}%' ";
