我试图让WooCommerce来从亚马逊API的价格，但我很失败。我在PHP中很糟糕，但这是迄今为止我所拥有的。我无法让它工作。亚马逊API和Woocommerce桥梁
我正在使用我在线发现的模板来从Amazon API调用。这些都是文件：

下面就来访问我相信API文件：

/* The params need to be sorted by the key, as Amazon does this at
their end and then generates the hash of the same. If the params
are not in order then the generated hash will be different thus
failing the authetication process.
*/
ksort($params);
$canonicalized_query = array();
foreach ($params as $param=>$value)
{
$param = str_replace("%7E", "~", rawurlencode($param));

curl_setopt($ch, CURLOPT_TIMEOUT, 15);

{
return False;

else
{

这是我相信不会的价格WooCommerce功能：
function woocommerce_get_formatted_product_name($product) {
if (! $product || ! is_object($product))
return;
if ($product->get_sku())
$identifier = $product->get_sku();
elseif ($product->is_type('variation'))
$identifier = '#' . $product->variation_id;
else
$identifier = '#' . $product->id;
if ($product->is_type('variation')) {
$attributes = $product->get_variation_attributes();
$extra_data = ' – ' . implode(', ', $attributes) . ' – ' . woocommerce_price($product->get_price());
} else {
$extra_data = '';
}
return sprintf(__('%s – %s%s', 'woocommerce'), $identifier, $product- >get_title(), $extra_data);
}
这是我已经添加到functions.php文件中，希望能够让所有人都在一起，可悲的是，它不工作:(
