Getting Crazy with Form Themes

Tip: This course is built on Symfony 3, but most of the concepts apply just fine to Symfony 4.

We already learned all the form basics. But, controlling how you render your forms? That's a huge and super-fun topic all on its own. Themes! Form variables! Rainbows! Let's go!

• Creating your own form theme
• Controller form variables
• Using form variables in your theme
• Rendering a field 100% by hand
• Controller variables in your form type
• Adding a "help" text system that renders for all fields
• Leveraging a FormTypeExtension to tweak any field in your system
• Customizing how a single field renders

This stuff is black magic: learn these fundamentals, and you'll be unstoppable!
