我发现这篇文章使用插件而不是主题来覆盖Woocommerce模板： https://www.skyverge.com/blog/override-woocommerce-template-file-within-a-plugin/
它似乎几乎可以工作，但它不适用于woocommerce / templates目录中的任何模板（如single-product.php或content-single-product.php）。
为了说明，我有这个过滤器：
add_filter('woocommerce_locate_template', array($this, 'woocommerce_locate_template'), 10, 3);
调用此函数：
public function woocommerce_locate_template($template, $template_name, $template_path) {
global $woocommerce;
al_log('Looking for ' . $template . ', ' . $template_name . ', ' . $template_path);
$_template = $template;
if (! $template_path) $template_path = $woocommerce->template_url;
$plugin_path = $this->my_plugin_path() .'/woocommerce/';
//look within passed path within the theme. This is the priority
$template = locate_template(
array(
$template_path . $template_name,
$template_name,
)
);
//modification: get the template from this plugin, if it exists
if (!$template && file_exists($plugin_path . $template_name))
$template = $plugin_path . $template_name;
//use default template
if (! $template) {
$template = $_template;
}
return $template;
}
导致这些日志行：

正如您所看到的，它永远不会在woocommerce / templates目录的根目录中寻找任何东西。有关为什么过滤器不适用于single-product.php或content-single-product.php的任何想法？
我目前在我的插件文件夹的根目录中有一个woocommerce文件夹，里面有一个单个product.php文件，顶部附近有一个die语句，所以我应该立即看看它是否正常工作。我确实在我的主题的woocommerce文件夹中放了相同的single-product.php文件，它在那里工作，但不是从插件。我应该使用不同的钩子吗？请指教。
