Hi,

We have observed two major bugs in the ‘WooCommerce Australia Post Shipping With Tracking’ (version 2.0.8)plugin which are preventing us from using this in a production environment. These issues seem to stem from the fact that the plugin is assuming that all products have all dimensions and weights set (which is not always the case).

Issue 1 – Blank ‘Edit order’ pages in admin backend (php error):
PHP error message:
Fatal error: Uncaught Error: Call to a member function get_packtype() on null in /home/runfaster/public_html/wp-content/plugins/australia-post-woocommerce-shipping/includes/class-wf-packing.php:155 Stack trace: #0 /home/runfaster/public_html/wp-content/plugins/australia-post-woocommerce-shipping/includes/class-wf-australia-post-shipping-admin.php(1175): WF_Boxpack->pack() #1 /home/runfaster/public_html/wp-content/plugins/australia-post-woocommerce-shipping/includes/class-wf-australia-post-shipping-admin.php(1931): wf_australia_post_shipping_admin->box_packing(Object(wf_order)) #2 /home/runfaster/public_html/wp-admin/includes/template.php(1050): wf_australia_post_shipping_admin->wf_australia_post_metabox_content(Object(WP_Post), Array) #3 /home/runfaster/public_html/wp-admin/edit-form-advanced.php(695): do_meta_boxes(Object(WP_Screen), ‘side’, Object(WP_Post)) #4 /home/runfaster/public_html/wp-admin/post.php(173): include(‘/home/runfaster…’) #5 {main} thrown in /home/runfaster/public_html/wp-content/plugins/australia-post-woocommerce-shipping/includes/class-wf-packing.php on line 155

This is a PHP error, the variable $box is not available at this point in the code execution. Not sure what you were trying to achieve here. Commenting out line 155 seems to fix the issue (and I can’t see any side effects).

Issue 2 – Error message displayed on frontend:
On product listing pages, the error “Product #a7ab52931fe5626d6d5c50554c8ce1cb is missing dimensions. Aborting.” is displayed, event with WP_DEBUG disabled. This error message appears to display whenever a listed product does not have it’s dimensions set. This error message is printed from line 1579 of includes/class-wf-australia-post-shipping.php

A side-effect of this error message is that it prevents add-to-cart redirects (to the cart page) from functioning.

This error message should only display when WP_DEBUG (or another debug setting) is enabled. Or, better yet, it should be possible to set default dimensions as a fallback for when dimensions are not set.

Feature request – default dimensions:
As mentioned above, I would like to request that settings for default dimensions be available on the settings page. For our use, all products have the same (or similar) dimensions. As such, it would be much simpler to just set one default than manually set shipping dimensions for all products and variations. This would itself fix the above two errors (though best that you fix them directly as well).
