class Blog_Model extends SENE_Model{
  var $tbl = 'd_order';
  var $tbl_as = 'dor';
  var $tbl2 = 'b_user';
  var $tbl2_as = 'bu';
  public function __construct(){
    parent::__construct();
    $this->db->from($this->tbl,$this->tbl_as);
  }
  public function getNow($id){
    $this->db->select("$this->tbl2_as.fname",'fname',0);
    $this->db->select("$this->tbl_as.date_order",'date_order',0);
    $this->db->join($this->tbl2,$this->tbl2_as,'id',$this->tbl_as,'b_user_id','');
    $this->db->where_as("DATE($this->tbl_as.date_order)","CURRENT_DATE()","AND","=",0,0);
    return $this->db->get();
  }
  public function getYesterday($b_user_id){
    $this->db->select("$this->tbl_as.*, $this-tbl_as.status_text",'status_text',0);
    $this->db->select("$this->tbl2_as.fname",'fname',0);
    $this->db->select("$this->tbl2_as.email",'email',0);
    $this->db->where_as("$this->tbl_as.status_text",$this->db->esc("order_invoice"),"AND","=",0,0);
    $this->db->where_as("DATE(date_order)","DATE_SUB(CURRENT_DATE(), INTERVAL 1 DAY)","AND","=",0,0);
    return $this->db->get();
  }
}

  • like%
  • %like
  • %like%

  • notlike%
  • %notlike
  • %notlike%
