如何绕过 CodeIgniter 中不允许的键字符

Question

我在 CodeIgniter 中的 Disallowed Key Characters 中找到解决方案时遇到了这个问题。我的问题是，我希望 £ 符号将通过我的网址传递。

例如，

• 我有这个产品testing-product-nutella。
• 我想在testing-product-nutella£ 之外添加一个£ 符号，有点像这样。 下面是我的代码

//--------------------------------------------- ------------------------------------// //--------------------------> 建立产品列表数据---------------- ----------// //------------------------------------------------ ---------------------------------//

        $prod_list              = Array();

        foreach($prods_query as $prod)
        {
            //echo htmlentities($prod['prod_name']);
            //print_r($prod);

            //$prod_name_url        = Make_into_url($prod['prod_name']);
            $prod_name_url      = htmlentities($prod['prod_name']);
            print_r($prod_name_url);

            // get the minimum order quantity and price from db
            if ($min_price = $this->Price_model->Get_listing_price($prod['prod_id']))
            {
                $min_order_qty      = $min_price['qty_value'];
                $min_order_price    = $min_price['price_amount'] > 0 ? number_format($min_price['price_amount'], 2) : false;
            }
            else
            {
                // this shouldn't happen but just in case...
                $min_order_qty      = "";
                $min_order_price    = "";
            }

            // get the default image for the product from the database
            $default_pic_row        = $this->Picture_model->Get_default_product_picture($prod['prod_id']);

            // get a list of all the special categories that a product is in
            $product_spec_cats      = $this->Special_category_model->Get_product_special_cats($prod['prod_id']);

            // is the product on special offer, if so, get the details
            $product_spec_off       = $this->Special_offer_model->Get_product_special_offer_details($prod['prod_id']);



            $nameUrl = urlencode($prod_name_url);
            echo "<pre>";
            echo $nameUrl;
            echo "</pre>";

            $prod_list[]            = Array(
                                            "prod_id"           => $prod['prod_id']
                                            ,"prod_name"        => urldecode($nameUrl)
                                            ,"prod_min_price"   => $min_order_price
                                            ,"prod_min_qty"     => $min_order_qty
                                            ,"prod_desc"        => $prod['prod_desc']
                                            ,"prod_code"        => $prod['prod_code']
                                            ,"prod_pic_thumb"   => $default_pic_row['pic_thumb']
                                            ,"product_colours_image"    => ""
                                            ,"prod_spec_cats"   => $product_spec_cats
                                            ,"prod_spec_off"    => $product_spec_off
                                            );
        }

当我尝试添加 £ 符号时，它显示不允许使用键字符。我希望当我添加特殊字符并传入 url 时，产品将通过特殊字符显示。

我尝试查看system/libraries/Input.php 文件中的文件并尝试更改function _clean_input_keys 中代码的一个小位，但它没有用。有人可以帮我弄清楚这件事吗？非常感谢任何帮助。

TIA

您必须对井号进行 url 编码。构建您的 url 字符串，然后将其传递给 php urlencode($url) 函数，该函数会将其转换为允许的字符：“%a3”代表“£”

要检索它，请使用urldecode($url)
