Tabs with WooCommerce Print Products-plugin

Hi @eramikkola,

I could not find any developer information about WooCommerce Print Products. Do you know if they have filters you can use for the fields? You’ll need to use a filter to loop through the data. I can write the code if you can help locate where to put it (i.e. a filter that lets you hook into a field).

Unfortunately it’s a paid plugin so I can’t download and test it out myself.

Let me know,
Kevin.

OK, hold on – I will send them a message ?? Thanks!

Hello Kevin, Db-Dzine replied:

Hi there,
as we use the native “get_post_meta” function your deveoper could hook into the get_post_metadata filter:

add_filter(‘get_post_metadata’, ‘yikes_woo_products_tabs’, 10, 4);

Then of course he has to check if $_GET[‘print-product’] == “pdf”.

Ahh, that’s what I was looking for. I’m still not 100% sure how to approach this because ideally we want to return an array (e.g. multiple tabs and multiple titles). I guess we can initially try this by returning a single string with all of the tab titles and content. Let me know how this works…

Try this snippet – you can add it to your functions.php file.

add_filter( 'get_post_metadata', 'add_yikes_woo_product_tabs_to_pdf', 10, 4 );

function add_yikes_woo_product_tabs_to_pdf( $null, $post_id, $meta_key, $single ) {

	if ( ! isset( $_GET['print-product'] ) || isset( $_GET['print-product'] ) && $_GET['print-product'] !== 'pdf' || $meta_key !== 'yikes_woo_products_tabs' ) {
		return $null;
	}

	$product_tabs = get_post_meta( $post_id, 'yikes_woo_products_tabs', true );

	$html = '';

	foreach( $product_tabs as $tab ) {

		if ( ! empty( $tab['title'] ) ) {
			$html .= '<h2>' . $tab['title'] . '</h2>';
		}

		if ( ! empty( $tab['content'] ) ) {
			$html .= '<div class="yikes-print-product-tabs">' . $tab['content'] . '</div>';
		} 
	}

	return $html;
}

Cheers,
Kevin.

I added this on theme functions.php (Avada).
No changes. The same text “array”. I know there function.php’s here and there. Did I place it in a wrong one?

If Avada is your active theme, then the code is in the right place. I figured this might take some iterations. I think the issue is with the ‘scoping.’ We have a few things to try still. Try this:

add_filter( 'get_post_metadata', 'add_yikes_woo_product_tabs_to_pdf', 10, 4 );

function add_yikes_woo_product_tabs_to_pdf( $null, $post_id, $meta_key, $single ) {

	if ( ( ! isset( $_GET['print-product'] ) ) || ( isset( $_GET['print-product'] ) && $_GET['print-product'] !== 'pdf' ) || ( $meta_key !== 'yikes_woo_products_tabs' ) ) {
		return $null;
	}

	$product_tabs = get_post_meta( $post_id, 'yikes_woo_products_tabs', true );

	$html = '';

	foreach( $product_tabs as $tab ) {

		if ( ! empty( $tab['title'] ) ) {
			$html .= '<h2>' . $tab['title'] . '</h2>';
		}

		if ( ! empty( $tab['content'] ) ) {
			$html .= '<div class="yikes-print-product-tabs">' . $tab['content'] . '</div>';
		} 
	}

	return $html;
}

I changed the theme to its child and added the code to its functions.php.

But no changes, not yet ??

I’m questioning if the $_GET['print-product'] == 'pdf' was the correct flag to check…

Let’s try again…

add_filter( 'get_post_metadata', 'add_yikes_woo_product_tabs_to_pdf', 10, 4 );

function add_yikes_woo_product_tabs_to_pdf( $null, $post_id, $meta_key, $single ) {

	if ( ! isset( $_GET['print-product'] ) || $meta_key !== 'yikes_woo_products_tabs' ) {
		return $null;
	}

	$product_tabs = get_post_meta( $post_id, 'yikes_woo_products_tabs', true );

	$html = '';

	foreach( $product_tabs as $tab ) {

		if ( ! empty( $tab['title'] ) ) {
			$html .= '<h2>' . $tab['title'] . '</h2>';
		}

		if ( ! empty( $tab['content'] ) ) {
			$html .= '<div class="yikes-print-product-tabs">' . $tab['content'] . '</div>';
		} 
	}

	return $html;
}

Would you like to see WPP files? I think they would get mad if I share some files privately with you ??

Email me at kevin at yikesinc .com

You have an email.

Agh, the key is print-products, not print-product.

Try this:

add_filter( 'get_post_metadata', 'add_yikes_woo_product_tabs_to_pdf', 10, 4 );

function add_yikes_woo_product_tabs_to_pdf( $null, $post_id, $meta_key, $single ) {

	if ( ( ! isset( $_GET['print-products'] ) ) || ( isset( $_GET['print-products'] ) && $_GET['print-products'] !== 'pdf' ) || ( $meta_key !== 'yikes_woo_products_tabs' ) ) {
		return $null;
	}

	$product_tabs = get_post_meta( $post_id, 'yikes_woo_products_tabs', true );

	$html = '';

	foreach( $product_tabs as $tab ) {

		if ( ! empty( $tab['title'] ) ) {
			$html .= '<h2>' . $tab['title'] . '</h2>';
		}

		if ( ! empty( $tab['content'] ) ) {
			$html .= '<div class="yikes-print-product-tabs">' . $tab['content'] . '</div>';
		} 
	}

	return $html;
}

OK, now something happens:

Thank you Kevin. After removing the infinite loop it works like a charm ?? Wonderful!
