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    $search2 = $term1  ?"and username like '%{$term1}%' ":'';//增加查询报名表编号    $table = load::sys_class('tabledata', 'new');    //$where = "lang='cn' {$search} {$search2}"; //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[] = " 错题集";    $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    $search2 = $term1  ?"and username like '%{$term1}%' ":'';//增加查询报名表编号    $table = load::sys_class('tabledata', 'new');    //$where = "lang='cn' {$search} {$search2}"; //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[] = " 错题集";    $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}%' ";
