Fetching non formatted Product values in WooCommerce - php

Question

I have below formatting for microdata and adding this on content-single-product.php WooCommerce template. Below is the code I am trying to add:
<div itemscope itemtype="http://schema.org/Product">
<meta itemprop="name" content="Product Name">
<div itemscope itemtype="http://schema.org/Offer">
<meta itemprop="sku" content="Product SKU">
<meta itemprop="price" content="Product Price" />
<meta itemprop="priceCurrency" content="Price Currency ex. INR" />
<meta itemprop="category" content="Category Name">
<meta itemprop="availability" content="http://schema.org/InStock" />
</div>
<div itemscope itemtype="http://schema.org/PriceSpecification">
<meta itemprop="minPrice" content="Special Price">
<meta itemprop="validFrom" content="Sale Start Date">
<meta itemprop="validThrough" content="Sale End Date">
</div>
<div itemscope itemtype="http://schema.org/Thing">
<meta itemprop="image" content="Product Image URL">
<meta itemprop="description" content="Product Description">
</div>
</div>
In this content-single-product.php template, I am adding some code below this line:
<div itemscope itemtype="<?php echo woocommerce_get_product_schema(); ?>" id="product-<?php the_ID(); ?>" <?php post_class(); ?>>
I am using WooCommerce functions to fetch product details, but it returns HTML formatted values and I need non-formatted product values.
Here are the TAGs details:
1. Tags for Product Basic Details
Product Name:
<meta itemprop="name" content="Product Name">
Assign product name under CONTENT . This specifies the product title and will be shown to users during search.
Product SKU Code
<meta itemprop="sku" content="Product SKU">
Assign unique product code for your product.
Product URL:
<meta itemprop="url" content="Product URL">
This tag contain product page URL from your website. This may be like http://www.YourWebsiteName.com/ProductName.php
Product Category
<meta itemprop="category" content="Category Name">
Assign Category Name under which your product is listed on your website.
Product Picture
<meta itemprop="image" content="Product Image URL">
This tags contains product image url. You need to put your product image full url here.
For example: http://www.YourWebsite.com/images/product_image.png
Product Description
<meta itemprop="description" content="Product Description">
Include product detail here.
2. Tags for Price
Price Currency:
<meta itemprop="priceCurrency" content="INR" />
Mention your product currency here.
Product Sale Price:
<meta itemprop="price" content="Product Price" />
This tags will contain product sale price/mrp. This is actual price above which product is not available in market. The price should be a number without separators between thousands or spaces (e.g. '8.99').
Product Special Price:
<meta itemprop="minPrice" content="Special Price">
Provide discounted price, offer price or special price for the products. This is not mandatory but important to get top listing in search results. If left blank, system will assign value 0 automatically. The price should be a number without separators between thousands or spaces (e.g. '8.99').
Special Price Start Date:
<meta itemprop="validFrom" content="Sale Start Date">
If Discounted price is offered, mention special price start date in DD/MM/YYYY format. If blank, system will assign current date automatically.
Special Price End Date:
<meta itemprop="validThrough" content="Sale End Date">
If Discounted price is offered, mention special price end date in DD/MM/YYYY format. If blank, system will assign date after 30 days automatically.
Thanks.

You need to get the current Product object and for this you will use together get_the_id() WordPress function with wc_get_product() WooCommerce function this way:
$product = wc_get_product(get_the_ID()); // Getting the Product object from current post ID
With that $product object you can access to any raw data for the current product.
You can use all WC_Product class properties and magic properties using the arrow syntax:
echo $product->property_slug; // displays the product property (if is a string value)
(Here property_slug should be replaced by one of the properties listed in WC_Product class).
$product_id = $product->id;
$product_type = $product->product_type;
$product_post_object = $product->post; // see below
With the post property you can access to all post object properties (just as in wp_post table):
$product_slug = $product->post->post_name;
$product_title = $product->post->post_title;
$product_description = $product->post->post_content;
$product_short_description = $product->post->post_excerpt;
Then using WC_Product class methods, you will get the following:
$product_sku = $product->get_sku(); // or $product->sku
$product_url = $product->get_permalink();
// As a product can be in many categories (array)
$product_categories_array = get_the_terms( $product->id, 'product_cat' );
// The categories in a coma separated string
$product_categories_string = $product->get_categories();
To get the currency you will use dedicated function get_woocommerce_currency()
For the prices you will use related WC_product properties:
$product_price = $product->price;
$product_reg_price = $product->regular_price;
// Product Sale price
$product_sale_price = $product->sale_price;
// Scheduled Sale price dates (timestamps)
$product_sale_start_ts = get_post_meta($product->id, '_sale_price_dates_from', true);
$product_sale_end_ts = get_post_meta($product->id, '_sale_price_dates_to', true);
To format Product Scheduled Sale price dates in DD/MM/YYYY format, as they are stored in database as timestamps values, we will use PHP date() function this way:
$product_sale_start_ts = get_post_meta($product->id, '_sale_price_dates_from', true);
$product_sale_start_date = date('d/m/Y', $product_sale_start_ts);
$product_sale_end_ts = get_post_meta($product->id, '_sale_price_dates_to', true);
$product_sale_end_date = date('d/m/Y', $product_sale_end_ts);
You can also access to this product meta data using get_post_meta() WordPress function, for example to get the SKU you will use:
$product_sku = get_post_meta($product->id, '_sku', true);
For product image The dedicated function is get_the_post_thumbnail() function:
$product_image = get_the_post_thumbnail( $product_id, 'shop_single' );
But as a product can have or not an image, or even a gallery of images you should look at the code in woocommerce templates > single-product > product-image.php template…
