How to use files conditionally in WordPress? - php

Question

I want to use a file conditionally upon user input. I am using WooCommerce templates in my child theme. Of course, the file (content-single-product.php) is customized in the child theme. However, I also wish to give users an option to use the default WC file if they want to. In short, I want to use that file conditionally which user will choose.
I am using the PHP copy() and unlink() functions. I just want your expert opinion if this is the best solution or if you have any suggestions better than mine. Here are the functions in my child theme.
/*...for copying the file from a child theme folder to the woocommerce folder...*/
function ac_wc_files_to_theme()
{
$theme_dir = get_stylesheet_directory() . '/woocommerce/files/content-single-product.php';
$theme_dir_file = get_stylesheet_directory() . '/woocommerce/content-single-product.php';
if (!copy($theme_dir, $theme_dir_file)) {
echo "failed to copy $theme_dir to $theme_dir_file...\n";
}
}
/*...for removing the file from a the woocommerce folder...*/
function ac_wc_delete_wc_file(){
$fileArray = array(
get_stylesheet_directory() . '/woocommerce/content-single-product.php'
);
foreach ($fileArray as $value) {
if (file_exists($value)) {
unlink($value);
} else {
echo 'file not found';
}
}
}
/*...calling the options from the theme settings area....*/
if (get_option('ac_wc_default_single') == 1) {
add_action('init', 'ac_wc_delete_wc_file');
remove_action('init', 'ac_wc_files_to_theme');
}
else {
add_action('init', 'ac_wc_files_to_theme');
remove_action('init', 'ac_wc_delete_wc_file');
}
The codes are working fine. Just I need your view if this will do. Thanks

Here's my best guess at filtering the template without extensive testing.
// change the default template path to `woocommerce/files`
function ac_wc_override_template_path(){
return 'woocommerce/files/';
}
add_filter( 'woocommerce_template_path', 'ac_wc_override_template_path' );
// now filter the woocommerce template
function ac_wc_override_single_product($template, $template_name, $template_path) {
$alt_template = '';
if ($template_name == 'content-single-product.php') {
$alt_template = locate_template( trailingslashit( $template_path ) . 'content-single-product-1.php' );
}
if( $alt_template && get_option( 'use_my_themes_templates' ) ){
return $alt_template;
} else {
return $template;
}
}
add_filter('woocommerce_locate_template', 'ac_wc_override_single_product', 20, 3);
