Question

Array to string conversion，该怎么解决？

Answer 1

在$this->smarty->assign('mainid','theDiv'.$this->p)的前面加上 print_r($this->p);
改成：
function showPageV($id,$vnum)
{
$this->pageModel->id=$id;
$this->pageModel->get_entries();
$ret = $this->pageModel->query->result_array();
$this->smarty->assign($vnum,$ret[0]);
$this->smarty->assign('mainid','theDiv'.$this->p);
