可重用的自定义Symfony FormType

Question

I have created a custom Symfony FormType which helps to parse date from a string. (Project is available on my Github https://github.com/ThBM/date-text-type )

In order to be able to use this class again in other Symfony projects, I would like to wrap it into a composer package.

I tried to do the same as a Standard library but I have the following error when I run my Symfony app : Too few arguments to function DateTextType::__constuct.

It seems like Dependency Injection is not working : DateStringParserTransform is not injected in the DateTextType construtor when I build my form. Do you have any lead on how to properly package a Custome Symfony Component?

Thank you for your help.

I solved my problem.

DataTransformer should not be injected in the custom FormType. You could just use an instance of it in the buildForm function.

<?php 
public function buildForm(FormBuilderInterface $builder, array $options)
{
    parent::buildForm($builder, $options);
    $builder->addModelTransformer(new DateStringParserTransform());
}

I also follow this link in order to structure my package as a Symfony bundle. https://symfony.com/doc/current/bundles .
