![]() ![]() In the section “Structure” > “YAML Form” > “Settings”. ![]() These examples are best explored, but include form wizards, input masks (say for inputting IP addresses), state API, pagination, validation etc.īefore making your first complicated form, I recommend looking at some of these examples, but what is great is that everything is quite simple, and still only require a handful of lines of YAML to complete. Doing so will give you some great examples and templates to clone and use for more complicated forms. ![]() When you install YAML form, you have the option to enable two extensions: “YAML Form Examples” and “YAML Form Templates”. Which doesn’t make for a sophisticated form. Now the contact form only has a few attributes, textfield, textarea and email. But it’s good to also have ‘#required’ as true or false to determine if it’s required. You only really need two declarations: ‘#title’ (the name of the input) and ‘#type’ (such textfield, email, select, checkbox, file_upload etc). After the colon, the attributes are indented with two spaces. The name of a declaration (a field) is a single word (or words with underscores) followed by a colon. What you’ll see is the screen above.Īt this point you will notice a basic structure. Go to Structure > YAML form, then I recommend tapping on “edit” for the default “Contact Form”, the tap “Source (YAML)” to see a basic YAML structure. Once you’ve installed YAML form, it’s time to get started in making your first form. Site builders have not been forgotten, and there is a user interface (UI) so you can still select form elements and build forms without in a manner not dissimilar to Webform in D7.īut the point of this blog post is not just to talk about how much we enjoyed using YAML form, it’s to provide a few pointers for those getting started with YAML form, and we hope this helps. Even putting together file uploads to a private directory with restricted file formats and size requires only five YAML declarations (‘#title’, ‘#type’, ‘#max_filesize’, ‘#upload_location’, ‘#file_extensions’). Thus a large multi-page form with dozens of fields and conditional validation can be made in minutes. So to make a new field, you only need to write a few lines of code in YAML. Multipage, dozens of fields, save and return, everything you could hope for in a web form is supported, at scale.īut perhaps the greatest benefit is the fact you can script the forms in YAML. So all the great functionality of Webform, but with the integration and scalability of Entity Forms. ![]() However, YAML form uses Drupal Entities, meaning it is properly integrated with the rest of the system – so you can use the output to create Views and you can attach forms to other nodes and blocks. In terms of functionality, YAML form has almost reached parity with Webform from the D7 platform. YAML form was released in June 2016 and, in my opinion, is the best Drupal form solution so far. So much for our initial thinking!Įnter the YAML Aint Markup Language (YAML) form, and all is well. However, as the project progressed, the form requirements became a bit more complex, and we found ourselves stranded as Contact Form + Contact Storage was not quite suitable, and to get eForms to meet our requirements, we’d have use the Rules module which was not production ready in D8. Nevertheless, eForm and Contact Form are improving in maturity and we thought it was time to move to D8 with this project. As any Drupal advocate knows, the forms solution freely available in the D7 eco-system, Entity Forms and Webform, are very powerful and are a strong reason to stay on the D7 platform. One of the reasons we had decided to use D8 was that the initial forms requirements were not too sophisticated, and we believed that the existing D8 form solutions (eForm and Contact Form + Contact Storage) should cover the requirements. Up to now, the team had developed our production sites in Drupal 7 (D7), so we were all excited to build a new site in D8, and in doing our homework it really looked like it would fit with the requirements of the Society (or so we thought!). While we were working on the Royal Western Australian Historical Society project, we made the decision to develop their web site in Drupal 8 (D8). ![]()
