How to create your own theme in Symfony?

Creating your Own Form Theme¶. Symfony uses Twig blocks to render each part of a form field labels, errors, text fields, tags, etc. A theme is a Twig template with one or more of those blocks that you want to use when rendering a form.

In other words, you can change the application behavior by changing which configuration files are loaded. That’s the idea of Symfony’s configuration environments. A typical Symfony application begins with three environments: dev (for local development), prod (for production servers) and test (for automated tests ).

When using the only keyword, none of Symfony’s built-in form themes ( form_div_layout.html.twig, etc.) will be applied. In order to render your forms correctly, you need to either provide a fully-featured form theme yourself, or extend one of the built-in form themes with Twig’s use keyword instead of extends to re-use the original theme contents.

Symfony uses Twig blocks to render each part of a form field labels, errors, text fields, tags, etc. A theme is a Twig template with one or more of those blocks that you want to use when rendering a form.

In addition to form themes, Symfony allows you to customize the way fields are rendered with multiple functions to render each field part separately (widgets, labels, errors, help messages, etc.) The recommended way of processing forms is to use a single action for both rendering the form and handling the form submit.

An array of all the names of the parent types. A unique key which is used for caching. Whether or not a field is actually a holder for a group of children fields (for example, a choice field, which is actually a group of checkboxes). The normalized data of the type. If true, disabled=”disabled” is added to the field.

Each field type has a parent type (e.g. the parent type of textarea is text, and the parent type of text is form) and Symfony uses the fragment for the parent type if the base fragment doesn’t exist.
