email templates – Magento 2.3.5 getCustomer() always return null

I am trying to insert some custom customer variables I have from 3rd party module in magento emails.

But I always get null instead of customer object

MagentoSalesModelOrder::getCustomer()

Is getCustomer changed in magento 2.3.5

Anybody has this issue?

theming – Naming convention for field type templates?

The naming convention for fields is documented here, Twig Template naming conventions

  • field–node–(field-name)–(content-type).html.twig
  • field–node–(field-name).html.twig
  • field–node–(content-type).html.twig
  • field–(field-name).html.twig
  • field–(field-type).html.twig field.html.twig

But field--text-with-summary.html.twig is one of those that is harder/trickier to figure out from just looking at the Field Type.

To make Drupal life easy for this, you can enable Twig Debug. See Locating Template Files with Debugging

Now when you inspect element with browser, you can see which template file is being used (the one with the “x”) and what other available template file names (the ones with “*”) you could use.

templates – Can a link in WordPress contain a query string that is picked up as $_POST

This question is about a very specific circumstance.

  1. A template file can run a default category query with thumbnail, linked title and excerpt, or it can run a linked title only depending on a viewer choice. That is, once on the category page, the viewer can click a List Only option. https:// domain/category/ glossary-of-wood-terms ?format=list This part works fine.

  2. The second option (linked title only) should pick up the whole dataset, not a paginated dataset.

  3. Using a pre_get_posts, I can set the query to get the whole dataset (not paginated) with

$query->set( 'posts_per_page', -1 );

and an if test that will only run that code on a particular URL. Here is where the problem lies.

It turns out that WordPress sees the address as https://domain/category/glossary-of-wood-terms?category_name=glossary-of-wood-terms with the query string hidden. But WordPress is treating it as a $_POST variable not a $_GET variable.

What address should I used in the pre_get_posts test?

What’s the added value in the sophisticated use of C++ templates advocated by Alexandrescu and others?

In general terms, what’s the added value in using the techniques described in the iconic book “Modern C++ Design”? Is it simply the ability to write reusable code that’s easily extensible? Or are there particular classes of applications where development can be greatly facilitated through the use of such techniques?

templates – Swap WooCommerce product catalog ordering dropdown with buttons?

I’d like to swap the standard WooCommerce dropdown for ordering the product catalogue using buttons, yet no Google search for an easy method of doing this (or a plugin) has been fruitful.

I’m using a custom theme so any edits can be easily added!

Any suggestions as to the easiest method of displaying this as a group of buttons?

Thanks in advance,
Alex

design templates – I have 2 sets of buttons, how can I organize them for a better user experience?

I have 2 sets of buttons on a pop-up box on a website. Game 1 consists of several options from which the user can choose, i.e. option 1, option 2, etc. Another is "Previous" "Next" "Start Over". What will be the best arrangement for the buttons? I have tried both arrangements. I have attached the images. Please tell me if it's okay or if there is a much better way to organize the button. Thank you.

magento2 – Custom email templates sometimes break

I created a "new order" email template. Additionally, I updated the files in the following folder by moving them to the custom theme.

supplier / magento / module-sales / view / frontend / templates / email

When I have placed an order Sometimes it displays "html" tags on the body of the email. (See attached images).
If I resend the same email from the administration backend again, I get the correct content. I cannot understand why this is happening. Any help much appreciated.

Design Templates – Approach for Updating the State of a Function

All of the approaches you mentioned are valid, and no approach seems entirely natural in Python.

Passing event reminders as arguments is usually the most appropriate approach, simply because it does not complicate the use of the function, and the event handler can be implemented with a low ceremony. Something like that:

def slow_function(*arguments, on_iteration=None, on_final=None):
  state = init(arguments)

  for x in whatever():
    state += x
    if on_iteration is not None:
      on_iteration(x)

  if on_final is not None:
    on_final()
  return state

def on_iteration(x):
  print("iteration:", x)

slow_function(1, 2, 3,
              on_iteration=on_iteration,
              on_final=lambda: print("done"))

If you have more than one of these events in a function, it will probably be more convenient to use an object:

# by default, handlers do nothing (null object pattern)
class SlowFunctionProgressHandler:
  def on_iteration(self, x): pass
  def on_final(self): pass

def slow_function(*arguments, event=SlowFunctionProgressHandler()):
  ...

# can implement/override a single event type
class MyProgessHandler(SlowFunctionProgressHandler):
  def on_iteration(self, x): print("iteration:", x)

slow_function(1, 2, 3, event=MyProgressHandler())

It also works well with type annotations!

Use of generators for yield progress messages may look elegant and may be appropriate, but in practice face a number of problems:

  • this strategy will not work well if the function is already a generator for some other reason
  • using return in a generator is possible, but quite tricky in practice
  • calling the function to extract progress messages is quite tedious

To illustrate the last point, you need to do something like this:

def slow_function(*arguments):
  state = init(arguments)

  for x in whatever():
    state += x
    yield ('iteration', x)

  yield ('final',)
  return state

progress = slow_function(1, 2, 3)
result = None
while True:
  try:
    message, *args = next(progress)
  except StopIteration as e:
    result = e.value
    break

  if message == 'iteration':
    ...
  elif message == 'final':
    ...

Consume a generator that can return East extremely tedious. If the generator doesn't come back, you can simplify it slightly using a for loop, but you still have to manually handle different different events. It is only when there is only one type of progression event that you get similar or lower complexity than recall based solutions.
