ecshop 头部库 page_header.lbi 里的{insert name='cart_info'} 什么意思

这是个调用的函数，函数位置在 includes/lib_insert.php 文件里的 insert_cart_info 函数部分；

/**
 * 调用购物车信息
 *
 * @access  public
 * @return  string
 */
function insert_cart_info()
{
    $sql = 'SELECT SUM(goods_number) AS number, SUM(goods_price * goods_number) AS amount' .
           ' FROM ' . $GLOBALS['ecs']->table('cart') .
           " WHERE session_id = '" . SESS_ID . "' AND rec_type = '" . CART_GENERAL_GOODS . "'";
    $row = $GLOBALS['db']->GetRow($sql);

    if ($row)
    {
        $number = intval($row['number']);
        $amount = floatval($row['amount']);
    }
    else
    {
        $number = 0;
        $amount = 0;
    }

    $str = sprintf($GLOBALS['_LANG']['cart_info'], $number, price_format($amount, false));

    return '<a href="flow.php" title="' . $GLOBALS['_LANG']['view_cart'] . '">' . $str . '</a>';
