Drupal 8 User Photo Update Form

Recently I had to come up with a simple way for users to change their member profile photo without requiring them to visit the user edit screen. Here’s the result:

Member Photo Output

First, I added a new Image field called “Member Photo” to the user account fields (machine name field_user_picture). Here are the settings I used:

  • Allowed extensions: png, gif, jpg, jpeg
  • File directory: users/[date:custom:Y]-[date:custom:m]
  • Max size: 10 MB
  • Checked: Enable alt field
  • Checked: Alt field required

Creating a Drupal 8 Route to a User Page with Dynamic User Object

It took me some time to figure out the right combination of properties to make this work.

My goal was to create a form that lives at /user/UID/photo (think /user/1/edit).

I wanted the user object to be passed into the form as an argument.

Here’s the mymodule.routing.yml file:

Here’s the src/Form/ProfilePhoto.php file: Read more ›

Drupal 8 Search API Tips

Here are some quick tips for configuring Search API for Drupal 8.

Easy Indexing

If you’re like me you rely heavily on Display Modes (aka View Modes) for your entity types. The most convenient way to get Search API to index your data is to use the Search Index view mode on any entity types you will index. If you’re using Display Suite you may want to choose a layout that doesn’t include authoring information, published date, etc. Just fill this view mode, in each entity type, with the fields you want to index. If you plan to use this to drive the output, you should also hide labels and do whatever else will ensure clean output; more on this later.

I suggest indexing the Title (in the case of content types) separately. More on that in the Boost notes below. Read more ›

Tideways and Xhgui using DevDesktop and Docker

THIS POST IS UNFINISHED. Use at your own risk. I needed to share with a colleague, so I’m just getting it out into the world. Your Mileage May Vary!

I’ve been working on some large Drupal 8 migrations and have been wanting to profile them for some time due to a few migrations taking far more time than I expected. Acquia DevDesktop, which I happen to be using for this site, offers xhprof in the older PHP environments, but I wanted to get something setup in PHP 7.

For PHP 7 the recommendation is to use Tideways; it’s a modern fork of xhprof. After collecting (tracing/profiling) the data with Tideways you need a way to analyze the data. I used a Docker environment to get Xhgui running. Here’s what a few xhgui screens look like. The best part is that nearly everything is clickable so you can drill down to figure out what’s slow, and why! Read more ›

Block Caching “Gotcha” in Drupal 8

I recently had a fight with the Block system in Drupal 8. To be brief, if you’re trying to disable caching on a block, make sure to set the #cache element regardless of whether the block has output or not.

This does not work (empty result gets cached):

 

This does work (nothing gets cached, as desired):

Send email after Migrate Import in Drupal 8

Here’s an example of a barebones event subscriber to send an email when a Drupal migration finishes importing. The success vs failure logic isn’t working correctly, but you’ll get the gist.

The file structure looks like this:

Python Faker with the Fake App (Mac OS)

Fake App is a fantastic way to automate form filling, especially for folks without coding skills. The click-and-drag to target an element lets you quickly build your macros.

Python Faker is a utility library that I leverage with tools like Fake App, Alfred, Keyboard Maestro, etc. to generate realistic dummy text. This blog post shows one method of how to get Python Faker data into Fake App; I imagine there might be a simpler way but this works well and is fairly intuitive.

The idea is to just write the Faker output to a file and read that file into a variable for use in Faker. With this method you could even store variables for re-use. For example, if you had three fields: First Name, Last Name, and Full Name, you could easily store the first and last names to separate files and use both values for the Full Name field. With the power of Faker your dummy text options are extensive; you can generate very realistic values for your form filling. See all of the “providers” here.

This example below took just minutes to setup (and it was the first time I’ve used this technique).

Setting up xdebug for PHP 7 in Acquia DevDesktop

The Acquia DevDesktop help page says:

The PHP 7 version currently included with Acquia Dev Desktop does not currently include Xdebug. You can download an updated version of Xdebug here .

Here are the actual steps I used. YMMV.
