Add custom content to WooCommerce product description - php

Question

I'm trying to inject some text in my description ending.
Is it possible with filter?
Or do i need to do this via child theme?
Been trying to find the hook for description but can only find one for short description.
Example:
This is a description.
Just some sample text to fill the description out.
What i want is to inject "This is the last line in the description" So the hole description would look like this.
This is a description.
Just some sample text to fill the description out.
This is the last line in the description
The code i have for injecting text before short description is this:
add_filter( 'woocommerce_short_description', 'single_product_short_descriptions', 10, 1 );
function single_product_short_descriptions( $post_excerpt ){
global $product;
if ( is_single( $product->id ) )
$post_excerpt = '<div class="product-message"><p>' . __( "Article only available in the store.", "woocommerce" ) . '</p></div>' . $post_excerpt;
return $post_excerpt;
}

You can use this custom function hooked in the_content filter hook this way:
add_filter( 'the_content', 'customizing_woocommerce_description' );
function customizing_woocommerce_description( $content ) {
// Only for single product pages (woocommerce)
if ( is_product() ) {
// The custom content
$custom_content = '<p class="custom-content">' . __("This is the last line in the description", "woocommerce").'</p>';
// Inserting the custom content at the end
$content .= $custom_content;
}
return $content;
}
Code goes in functions.php file of your active child theme (or active theme). Tested and works.
Addition - Force product description when is empty (if you want this custom text to be displayed):
add_filter( 'woocommerce_product_tabs', 'force_description_product_tabs' );
function force_description_product_tabs( $tabs ) {
$tabs['description'] = array(
'title' => __( 'Description', 'woocommerce' ),
'priority' => 10,
'callback' => 'woocommerce_product_description_tab',
);
return $tabs;
}
Code goes in function.php file of your active child theme (or active theme). Tested and works.
