Question

我遇到了一个奇怪的问题，我使用的是2.1版Codeigniter，问题是在config.php文件的第一行后面有空格就在这段代码之后

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');

长话短说我＆＃34;加入购物车＆＃34;如果之后有空格，按钮不起作用但是我试图通过

设置CI中的默认时间

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
date_default_timezone_set('Asia/Karachi');

它在本地服务器上工作正常，但在Live服务器上没有受到影响，即使在删除空格和默认时区后，实时版本的行为也是有线的，它不会将产品添加到卡上。
这是您可以检查的实时服务器版本＆＃34; 在线购物车＆＃34;选项选择
＆＃34;的伯格斯＆＃34;选项选择
＆＃34; 添加到购物车＆＃34;它将重定向到＆＃34; 查看产品＆＃34;页面我不知道它是如何发生的。
这是链接：193.42.156.121/hk
视图中两个链接的代码段：

蛞蝓）GT;？＆＃34;类=＆＃34;视图＆＃34;＆GT; 查看

 <li> 
   <a href="<?php echo site_url().'cart/fetch_product/'.$product->id; ?>" class="view">
      Add to
      <br>
      Cart
    </a> 
</li>

控制器看起来像这样，视图发送其链接：

    function add_to_cart($data='')
{

        $product_id     = $this->input->post('id');
        $quantity       = $this->input->post('quantity');
        $post_options   = $this->input->post('option');

        if (!empty($data)) 
        {   
            $product_id     = $data['direct_product']->id;
            $quantity       = 1;
            // print_r($data['product']);
             // $data['product']->track_stock = $data['product']->track_stock = 0;
            // echo $stock =$data['product']->track_stock ;
        }
        // Get a cart-ready product array
        $product = $this->Product_model->get_cart_ready_product($product_id, $quantity);
        // print_r($product);
        // die();
        //if out of stock purchase is disabled, check to make sure there is inventory to support the cart.
        // echo $this->config->item('allow_os_purchase')." Purcahse allow <br>";
        // echo (bool)$product['track_stock'].' Track stock <br>';
        // die();
        if(!$this->config->item('allow_os_purchase') && (bool)$product['track_stock'])
        {
            $stock  = $this->Product_model->get_product($product_id);

            //loop through the products in the cart and make sure we don't have this in there already. If we do get those quantities as well
            $items      = $this->go_cart->contents();
            $qty_count  = $quantity;
            foreach($items as $item)
            {
                if(intval($item['id']) == intval($product_id))
                {
                    $qty_count = $qty_count + $item['quantity'];
                }
                echo $qty_count."<br>";
            }

            if($stock->quantity < $qty_count)
            {

                $this->session->set_flashdata('error', sprintf(lang('not_enough_stock'), $stock->name, $stock->quantity));

        $start_time_in_24_hour  = date("H:i", strtotime($this->setting['opening_time']));
        $end_time_in_24_hour    = date("H:i", strtotime($this->setting['closing_time']));
        $timestamp = date("H:i", time());
        if(

            redirect($this->Product_model->get_slug($product_id));
        }

        if( ! $status['validated'])

我在这个功能中获得的每个值都是正确的但不知道我的链接
http://193.42.156.121/hk/cart/fetch_product/56 被重定向到
http://193.42.156.121/hk/veggie-burger
它是怎么做到的？有什么想法吗？

Answer 1

试试这样：

if(! ini_get('date.timezone')){
    date_default_timezone_set('GMT');
}

这样，它不会改变config.php文件中的任何其他内容

Answer 2

问题出在这里我是重定向到错误的链接，愚蠢我

 if(!($start_time_in_24_hour <= $timestamp && $end_time_in_24_hour <= $timestamp))
    {
        $this->session->set_flashdata('error', 'shop is closed');
        redirect($this->Product_model->get_slug($product_id));
    }

应该是这样的：

 if(!($start_time_in_24_hour <= $timestamp && $end_time_in_24_hour <= $timestamp) )
    {

        $this->session->set_flashdata('error', 'shop is closed');
        redirect('onlineOrders');
    }
