The autoloader expected class - php

Question

I created code for tags in symfony but I have this bug:
The autoloader expected class "Tag\TagBundle\Form\Types\TagsType" to be defined in file "/var/www/html/TagProject/vendor/composer/../../src/Tag/TagBundle/Form/Types/TagsType.php". The file was found but the class was not in it, the class name or namespace probably has a typo.
TagsType.php:
<?php
namespace Tag\TagBundle\Form\Types;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Tag\TagBundle\Form\DataTransformer\TagsTransformer;
use Symfony\Bridge\Doctrine\Form\DataTransformer\CollectionArrayTransformer;
use Symfony\Component\Form\FormBuilderInterface;
class TagsTypes extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options){
$builder
->addModelTransformer(new CollectionArrayTransformer(),true)
->addModelTransformer(new TagsTransformer(),true);
}
public function getParent(){
return TextType::class;
}
}
}
TagsTransformer.php:
<?php
namespace Tag\TagBundle\Form\DataTransformer;
use Symfony\Component\Form\DataTransformerInterface;
class tagsTransformer implements DataTransformerInterface {
public function transform($value){
dump($value);
return "";
}
public function reverseTransform($value){
}
}
PostType.php:
<?php
namespace AppBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
use Tag\TagBundle\Form\Types\TagsType;
class PostType extends AbstractType
{
/**
* {#inheritdoc}
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('name')
->add('content')
->add('tags',TagsType::class);
}
/**
* {#inheritdoc}
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\Post'
));
}
/**
* {#inheritdoc}
*/
public function getBlockPrefix()
{
return 'appbundle_post';
}
}

Answer 1

Your error is naming class.
You have TagsType.php is php file and your class name is TagsTypes:
You have to change class name:
class TagsTypes
to
class TagsType
