form_alter

I was tasked with breaking the user registration form of a Drupal 8 installation into a multi-step form. This was necessary because depending on what a user selected in step one, they were shown different form fields in step two.

To begin, I added all of the fields I needed to the user profile using the GUI. (/admin/config/people/accounts/fields). Then, I added the fields I needed to the manage form display/register tab (/admin/config/people/accounts/form-display/register).

I needed to redirect the user register form based on a role that the user wanted to apply for. To do this, I added a custom submit handler to the register form.

Today I needed to add the html character "»" to a Drupal 7 form value. The first thing I did was alter the form and add the » character to the end of the submit button's value. Upon reloading the form, I noticed that instead of the character being displayed, the plaintext was displayed.
