我正在尝试在购物车的opencart"估计运费和税费"部分中将运费排序更改为ASC。
我使用"uasort"更改了 php 中数组的排序，一切看起来都不错，但是当 json 循环在 tpl 中打印出来时，它的顺序又错了。
/目录/控制器/总计/运输.php
打印 php 数组时，它的顺序正确：
Array
(
[free] => Array
(
[title] => Free Shipping
[quote] => Array
(
[free] => Array
(
[code] => free.free
[title] => Free Shipping
[cost] => 0
[tax_class_id] => 0
[text] => $0.00
)
)
[sort_order] => 1
[error] =>
)
[usps] => Array
(
[title] => United States Postal Service
[quote] => Array
(
[00] => Array
(
[code] => usps.00
[title] => First-Class Mail Parcel
[cost] => 4.54
[tax_class_id] => 0
[text] => $4.54
)
[4] => Array
(
[code] => usps.4
[title] => USPS Retail Ground
[cost] => 7.29
[tax_class_id] => 0
[text] => $7.29
)
[1] => Array
(
[code] => usps.1
[title] => Priority Mail 2-Day
[cost] => 7.3
[tax_class_id] => 0
[text] => $7.30
)
)
[sort_order] => 2
[error] =>
)
)
以 json 格式正确打印出来
{"shipping_method":{"free":{"title":"Free Shipping","quote":{"free":{"code":"free.free","title":"Free Shipping","cost":0,"tax_class_id":0,"text":"$0.00"}},"sort_order":"3","error":false},"usps":{"title":"United States Postal Service","quote":{"00":{"code":"usps.00","title":"First-Class Mail Parcel","cost":4.54,"tax_class_id":"0","text":"$4.54"},"4":{"code":"usps.4","title":"USPS Retail Ground","cost":7.29,"tax_class_id":"0","text":"$7.29"},"1":{"code":"usps.1","title":"Priority Mail 2-Day","cost":7.3,"tax_class_id":"0","text":"$7.30"}},"sort_order":"2","error":false}}}
但是，最终结果以原始顺序显示它们
/catalog/view/theme/default/template/total/shipping.tpl
Please select the preferred shipping method to use on this order.
Free Shipping
Free Shipping - $0.00
United States Postal Service
Priority Mail 2-Day - $7.30
USPS Retail Ground - $7.29
First-Class Mail Parcel - $4.54
也许我只是累了，但似乎我错过了一些明显的东西。我做错了什么。
原始文件可以在这里查看...https://github.com/opencart/opencart/blob/master/upload/catalog/controller/total/shipping.phphttps://github.com/opencart/opencart/blob/master/upload/catalog/view/theme/default/template/total/shipping.tpl
它不起作用的原因是因为它还将数组存储在会话中，并且表单字段必须与原始货件类型键匹配（即"usps.00"与 [00]）。
<input type="radio" name="shipping_method" value="usps.00">
我只是猜测;我看起来不是很彻底。
因为我不知道在 json 中重新使用多维数组，所以我在"/catalog/controller/total/shipping.php"中复制了"$quote_data"数组，使用 usaort（） 排序成本然后使用 array_values（），因此原始密钥存储在会话中，json 获取修改后的密钥。
如果你想在这里使用我的黑客方法，它是...
取代
<?php
// START EDIT - FUNCTION TO RESORT BY PRICE/COST
function sortbycost ($a, $b) {
return $a['cost'] > $b['cost'];
}
//END EDIT
class ControllerTotalShipping extends Controller {
取代
if ($quote) {
// START EDIT - FUNCTION TO SORT BY QUOTE (PRICE/COST)
uasort($quote['quote'], 'sortbycost');
// ADDED SECOND ARRAY (DUPLICATE ARRAY TO BE STORED IN SESSION)
$quote_data2[$result['code']] = array(
'title' => $quote['title'],
'quote' => $quote['quote'],
'sort_order' => $quote['sort_order'],
'error' => $quote['error']
);
// REPLACE KEYS FOR JS LOOP
$quote['quote'] = array_values($quote['quote']);
// END EDIT
$quote_data[$result['code']] = array(
'title' => $quote['title'],
'quote' => $quote['quote'],
'sort_order' => $quote['sort_order'],
'error' => $quote['error']
);
}
取代
//$this->session->data['shipping_methods'] = $quote_data; // ORIGINAL
$this->session->data['shipping_methods'] = $quote_data2; // EDIT - KEEP DUPLICATE ARRAY WITH THE ORIGINAL KEYS IN SESSION
取代
//$json['shipping_method'] = $this->session->data['shipping_methods']; // ORIGINAL
$json['shipping_method'] = $quote_data; // EDIT - USE THE NEW KEYS
模板文件的javascript中重新排序数据可能会更好，但就像我说的，我不知道该怎么做。
