FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Installation
Follow this guide for the installation.
Usage
This section shows how to create a 3-step form flow for a user. The package provides 03 approaches but i will focus on one: One form type for the entire flow. This approach makes it easy to turn an existing (common) form into a form flow. We will use this FormType:
1. Create a flow class
2. Update the form type class
There is an option called flow_step you can use to decide which fields will be added to the form
according to the step to render.
3. Register your flow as a service
4. Setup your controller
4. Create a form template(view)
You only need one template for a flow.
The instance of your flow class is passed to the template in a variable called flow so you can use it to render the
form according to the current step.
Buttons
You can customize the default button look by using these variables to add one or more CSS classes to them:
asmitta_formflow_button_class_lastwill apply either to the next or finish buttonasmitta_formflow_button_class_finishwill specifically apply to the finish buttonasmitta_formflow_button_class_nextwill specifically apply to the next buttonasmitta_formflow_button_class_backwill apply to the back buttonasmitta_formflow_button_class_resetwill apply to the reset button
Example with Bootstrap button classes:
In the same way you can customize the button labels:
asmitta_formflow_button_label_lastfor either the next or finish buttonasmitta_formflow_button_label_finishfor the finish buttonasmitta_formflow_button_label_nextfor the next buttonasmitta_formflow_button_label_backfor the back buttonasmitta_formflow_button_label_resetfor the reset button
Example:
You can also remove the reset button by setting asmitta_formflow_button_render_reset to false.
The buttons are displayed in a div with the class _asmitta_formflowbuttons. You can override its rules in your CSS file.
Handle Unmapped Fields
If you have unmapped fields in your form, you can handle them at the end of the form fill.
In our previous example, assuming the first_name is unmapped we'll need to handle it ourself.
Symfony UX Turbo
Working with Symfony Turbo the flow in the view might not work correctly. You should disable it on that view or send a specific code with the controller.
-
Disabling Turbo: o disable Turbo on a specific page in Symfony, you can use the
data-turboattribute. For example: - Sending a http code with the controller:
