Adding the stock quantity in a custom table

Hi sorry, but while waiting for your answer I went thinking on about the solution and I imagine I got it! Since it may serve for others, I’d like to report here the procedure I adopted. Maybe you can also answer to a question (see at the bottom of the codes)

First of all I created a new function on the file class-wc-product-variation.php that is found in woocommerce/includes/
The function is more or less the modified copy of the get_formatted_name at line 741 of the file. My new function is called get_formatted_variations_name and returns a string which gives the title of the variation and the price. Here it is:

STEP 1

	/**
	 * Get product variation name. Used within admin.
	 *
	 * @return string Formatted product name, including attributes and price
	 */
	public function get_formatted_variations_name() {
		if ( $this->get_sku() ) {
			$identifier = $this->get_sku();
		} else {
			$identifier = '';
		}

		$formatted_attributes = $this->get_formatted_variation_attributes( true );
		$variation_name = substr($formatted_attributes, 27);
		$extra_data           = $variation_name . ' – ' . wc_price( $this->get_price() );

		return sprintf( __( '%s', 'woocommerce' ), $extra_data );
	}

STEP 2)
I created a new avia element called “calendar’ in which I call the function stated before, together with the stock data in a loop, in order to extract all variation for a determined product. In my case the product was called “CSR Expeditions Payment” and the variations are the dates of the cruises. The $loop passes all the products, and before outputting the data I need, I filter the product of interest (in this case CSR Expeditions Payment).

 
<?php
if( !class_exists( 'woocommerce' ) )
{
	add_shortcode('csr_calendar_button', 'avia_please_install_woo');
	return;
}

if ( !class_exists( 'avia_csr_calendar_button' ) )
{
	class avia_csr_calendar_button extends aviaShortcodeTemplate
	{
		/**
		 * Create the config array for the shortcode button
		 */
		function shortcode_insert_button()
		{
			$this->config['name']		= __('CSR Calendar', 'avia_framework' );
			$this->config['tab']		= __('Plugin Additions', 'avia_framework' );
			$this->config['icon']		= AviaBuilder::$path['imagesURL']."sc-button.png";
			$this->config['order']		= 23;
			$this->config['target']		= 'avia-target-insert';
			$this->config['shortcode'] 	= 'csr_calendar_button';
			$this->config['tooltip'] 	= __('Display the "CSR Calnedar" button for the current product', 'avia_framework' );
			$this->config['drag-level'] = 3;
			$this->config['tinyMCE'] 	= array('disable' => "true");
			$this->config['posttype'] 	= array('product',__('This element can only be used on single product pages','avia_framework'));
		}

		/**
		 * Editor Element - this function defines the visual appearance of an element on the AviaBuilder Canvas
		 * Most common usage is to define some markup in the $params['innerHtml'] which is then inserted into the drag and drop container
		 * Less often used: $params['data'] to add data attributes, $params['class'] to modify the className
		 *
		 *
		 * @param array $params this array holds the default values for $content and $args.
		 * @return $params the return array usually holds an innerHtml key that holds item specific markup.
		 */
		function editor_element($params)
		{
			$params['innerHtml'] = "<img />config['icon']."' title='".$this->config['name']."' />";
			$params['innerHtml'].= "<div class='avia-element-label'>".$this->config['name']."</div>";
			$params['content'] 	 = NULL; //remove to allow content elements
			return $params;
		}

		/**
		 * Frontend Shortcode Handler
		 *
		 * @param array $atts array of attributes
		 * @param string $content text within enclosing form of shortcode element
		 * @param string $shortcodename the shortcode found, when == callback name
		 * @return string $output returns the modified html string
		 */
		function shortcode_handler($atts, $content = "", $shortcodename = "", $meta = "")
		{
			$output = "";
			$meta['el_class'];
			
			global $woocommerce, $product;
			if(!is_object($woocommerce) || !is_object($woocommerce->query) || empty($product)) return;

			// $product = wc_get_product();
			
			$output .= "<div class='av-woo-calendar-button ".$meta['el_class']."'>";
			ob_start();?>
			
                <table cellspacing="0" cellpadding="2">

CONSIDERATIONS

1) It seems working by now, but I have to add it AFTER the product purchase button, otherwise the purchase button doesn’t appear… still have to figure out why

2) I still am trying to see where I can save my new function in the child theme folde. I tried to add it to a subfolder woocommerce/includes, but it doesn’t work like that. By now I left the new function in the original woocommerce file class-wc-product-variation.php, but it is not a good solution as if I update the plugin the modifications would be lost. HERE’S MY QUESTION: do you know where I should save it??

Thanks again
Elena

Hi Ismael, here I am.

To see how the code works please refer to the following link

As I was telling you, the csr-expeditions is the product with the variations that correspond to different date cruises. I added also gravity form to allow the possibility of adding the names of the participants if they are > 1. Just below the form I added the calendar that I described above

These where my steps:

1) added the new shortcodes in the child theme folder
2) added the new wc-class to the class-wc-product-variation.php file which STILL is in the woocommerce folder

Actually my problem is where I can save the class-wc-product-variation.php file in my child theme in order to keep it even if I update woocommerce. I had the same issue with another file of woocommerce that I modified (the form-shipping.php) and it doesn’t work if saved in my child- theme folder.
Do you have any suggestion?
