问题描述

我在尝试修改某些表时不断收到此错误.这是我的代码:

I keep getting this error while trying to modify some tables. Here's my code:

/**  <- line 320

        &$order_count, &$guest_count){
/* @var $guests_array ArrayObject */
    $sucess = false;
    if(sizeof($guests_array) >= 1){
        //$this->mysqli->autocommit(FALSE);
        //insert the guests into guest, person, order, seat
        $menu_stmt = $this->mysqli->prepare("SELECT id FROM menu WHERE

推荐答案

我不认为这样会起作用.当您关闭语句(例如 $menu_stmt->close();)时,您也会释放语句句柄.因此,第二次循环时,您将无法再使用准备好的语句.

I don't think it will work this way. When you close the statement (e.g. $menu_stmt->close();) you also deallocate the statement handle. So the second time through the loop you don't have the prepared statements available to work with anymore.

在循环执行完毕后尝试关闭语句.

Try closing the statements after the loop has finished executing.
