php - do_action - woocommerce_locate_template filter from plugin en lugar de theme

apply_filters

Question

Encontré este artículo sobre el uso de complementos en lugar de temas para anular una plantilla de WooCommerce: https://www.skyverge.com/blog/override-woocommerce-template-file-within-a-plugin/

Parece que casi funciona, pero no funciona para ninguna plantilla que esté en la raíz del directorio woocommerce / templates (como single-product.php o content-single-product.php).

Para ilustrar, tengo este filtro:

add_filter(''woocommerce_locate_template'', array($this, ''woocommerce_locate_template''), 10, 3);

llamando a esta función:

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; 
}

Como puede ver, nunca busca nada en la raíz del directorio woocommerce / templates. ¿Alguna idea de por qué ese filtro no funciona para single-product.php o content-single-product.php?

Actualmente tengo una carpeta woocommerce en la raíz de mi carpeta de plugins y dentro hay un archivo single-product.php con una sentencia de matriz cerca de la parte superior, por lo que debería ver inmediatamente si está funcionando. Puse el mismo archivo single-product.php en una carpeta de woocommerce en mi tema y funciona allí, pero no desde el complemento. ¿Hay un gancho diferente que debería usar? Por favor avise.
