getdata table表格数据join mysql方法

  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."

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}%' ";
