WooCommerce 2.7.0 Test Drive – Dealing With Deprecated Functions And Disallowed Direct Calls

WooCommerce 2.7.0 Test Drive – Dealing with Deprecated Functions and Disallowed Direct Calls

Decided to test WooCommerce 2.7.0 beta 3 locally for my Ianua Theme. As a theme author it is always important to see if a whole new version works for you or not and if not to fix the issues. I realized a lot of code for single product page display was deprecated as functions got renamed and a lot of calls could not be made directly to the $product class anymore.

Ran into this PHP notice on single product pages. The function:

get_gallery_attachment_ids

is now outdated and should be replaced by:

get_gallery_image_ids

Steps to Reproduce this Error

This was the actual error message delivered by xdebug so very thorough:

 PHP Notice: WC_Product::get_gallery_attachment_ids is <strong>deprecated</strong> since version 2.7! Use WC_Product::get_gallery_image_ids instead. in /srv/www/ianua.imagewize.com/current/web/wp/wp-includes/functions.php on line 3828

Outdated Templates: ❌Learn how to update

So I knew there were things I had to check out or fix. Just did not realize there were quite a few issues I had to deal with.

Product Image Template

So I checked product-image.php as that is where I deal with product images as I should.

Path to file:

/site/web/app/themes/ianua/woocommerce/single-product/product-image.php

and on line 25 I had:

$attachment_ids = $product->get_gallery_attachment_ids();

and as stated get_gallery_attachment_ids is outdated or deprecated. So I replaced it by get_gallery_image_ids . And this worked and the image gallery came back again without the error notice.

get_display_price Deprecated

And then other issues showed up. The function:

get_display_price

is outdated as well. So we had to deal with this too. The exact PHP notice in brief was:

Notice: WC_Product::get_display_price is <strong>deprecated</strong> since version 2.7! Use wc_get_price_to_display instead. in /srv/www/ianua.imagewize.com/current/web/wp/wp-includes/functions.php on line 3828

I found it inside:

/ianua.imagewize.com/site/web/app/themes/ianua/lib/extras.php

on line 1046:

 echo '<div class="six columns tab-whole product-content right"><span class="price">$' . $product->get_display_price() . '</span>';

I have it as part of an action I added as a replacement of

add_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_price', 10 );

Just replacing it with wc_get_price_to_display() got me another error

Fatal error: Uncaught Error: Call to undefined method WC_Product_Simple::wc_get_price_to_display() in /srv/www/ianua.imagewize.com/current/web/app/themes/ianua/lib/extras.php on line 1046

So I added:

$product->get_price_html()

which worked. It was inspired by the new:

/plugins/woocommerce/templates/single-product/price.php

And this worked like a charm. Will do some more testing later on of course. But let’s move on to the other notices shall we?

product_type called directly

Then I had a product_type called directly notice. Another direct call notice stating this should not be done basically.

[01-Mar-2017 06:55:56 UTC] PHP Notice:  product_type was called <strong>incorrectly</strong>. Product properties should not be accessed directly. Please see <a href="https://codex.wordpress.org/Debugging_in_WordPress">Debugging in WordPress</a> for more information. (This message was added in version 2.7.) in /srv/www/ianua.imagewize.com/current/web/wp/wp-includes/functions.php on line 4136

NB Woo Poly Integrations had similar issues mentioned in a ticket at their Github repo.

This was in the same extra.php file on line 1066:

 do_action( 'woocommerce_' . $product->product_type . '_add_to_cart' );

That is what happens when you use many filters. Might need to get rid of some of these soon. Anyways, I realized it now has to be

get_type()

based on /plugins/woocommerce/includes/class-wc-product-simple.php line 33. Again I may need to do some more testing.

Had a get_related is outdated notice:

[01-Mar-2017 08:18:11 UTC] PHP Notice:  WC_Product::get_related is <strong>deprecated</strong> since version 2.7! Use wc_get_related_products instead. in /srv/www/ianua.imagewize.com/current/web/wp/wp-includes/functions.php on line 3828

line 29 of the theme’s single-product/related.php I had

if ( ! $related = $product->get_related( $posts_per_page ) ) {

wc_get_related_products which again caused a fatal error as it could not find the method. This was I as I had it all wrong and just need to run the function and necessary arguments. So turned it into:

if ( ! $related = wc_get_related_products( $product->get_id(), $args['posts_per_page'] )) {
 return;
}

And now all product were displaying well.

Photoswipe

There also seems to be a new file for working with sliders in single products (beta one blog post mentions it here. It is Photoswipe. Somehow the code was injected at the bottom of the page in the footer. So I added my own in woocommerce/single-product/photoswipe.php . One with only the header code:

 

<?php
/**
 * Photoswipe markup
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/single-product/photoswipe.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see https://docs.woocommerce.com/document/template-structure/
 * @author WooThemes
 * @package WooCommerce/Templates
 * @version 2.7.0
 */

This as I use my own flex slider based one. That took care of that issue. I may use it for other projects though.

Backend Product Editing Issues

What I currently do have is working on the product details does not go well. It seems I cannot switch tabs to let’s say inventory or shipping. Will do some testing on this a little later on. Could be the fact that WooCommerce 2.7.0 is beta after all. But that seems to be an Advanced Custom Fields issue as I found this JavaScript error:

Uncaught Error: Option 'ajax' is not allowed for Select2 when attached to a <select> element.
