get multiple files from user

Sorry for my bad English.
Im new to oro and I want to get multiple files from user in my form and persist them.
I added my filed to my entity like this:

PHP

/** * * @var Collection $files * * @ORM\OneToMany(targetEntity="Oro\Bundle\AttachmentBundle\Entity\File", mappedBy="owner", * cascade={"all"}, orphanRemoval=true * )) * @ORM\JoinColumn(name="agent_file_id", referencedColumnName="id", onDelete="SET NULL") ** */ protected $files;

1 2 3 4 5 6 7 8 9 10 11

/**      *      * @var Collection $files      *      * @ORM\OneToMany(targetEntity="Oro\Bundle\AttachmentBundle\Entity\File", mappedBy="owner",      *    cascade={"all"}, orphanRemoval=true      * ))      * @ORM\JoinColumn(name="agent_file_id", referencedColumnName="id", onDelete="SET NULL")      **      */     protected $files;

I created a collection type like this:

PHP

class FileCollectionType extends AbstractType { public function setDefaultOptions(OptionsResolverInterface $resolver) { $resolver->setDefaults( array( 'allow_add' => true, 'allow_delete' => true, 'type' => 'oro_file', 'prototype_name' => '__s_name__', 'required' => false, 'show_form_when_empty' => false, 'handle_primary' => false, // 'options' => array( // 'data_class' => 'OroCRM\Bundle\ContactBundle\Entity\Contact' // ) ) ); } /** * {@inheritdoc} */ public function getParent() { return 'oro_collection'; } /** * {@inheritdoc} */ public function getName() { return 'websys_file_collection_type'; } }

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

class FileCollectionType extends AbstractType {       public function setDefaultOptions(OptionsResolverInterface $resolver)     {         $resolver->setDefaults(             array(                 'allow_add'            => true,                 'allow_delete'         => true,                 'type'                 => 'oro_file',                 'prototype_name'       => '__s_name__',                 'required'             => false,                 'show_form_when_empty' => false,                 'handle_primary' => false, //                'options'              => array( //                    'data_class' => 'OroCRM\Bundle\ContactBundle\Entity\Contact' //                )             )         );     }     /**      * {@inheritdoc}      */     public function getParent()     {         return 'oro_collection';     }       /**      * {@inheritdoc}      */     public function getName()     {         return 'websys_file_collection_type';     } }

I added my filed to form type like this:

PHP

->add( 'files', 'websys_file_collection_type', array( 'label' => 'oro.attachment.file.label', 'required' => false, ) )

1 2 3 4 5 6 7 8

->add(                 'files',                 'websys_file_collection_type',                 array(                     'label' => 'oro.attachment.file.label',                     'required' => false,                 )             )

After a clear cache and schema update my i went to my form page and it was great.
Now i could use + button to add more file fileds and i could choose some files.but when i submited the form with some files (i tried it with one or more files) i got this exception:

Fatal error: Call to undefined method Oro\Bundle\EntityConfigBundle\Config\Id\EntityConfigId::getFieldType() in /var/www/html/my_proj/vendor/oro/platform/src/Oro/Bundle/AttachmentBundle/Validator/ConfigFileValidator.php on line 64

so I started debuging:
i find out in ConfigFileValidator class in line 63 :

PHP

$fieldConfigId = $entityAttachmentConfig->getId();

1	$fieldConfigId = $entityAttachmentConfig->getId();

I saw, when I was using a simple file field before the $fieldConfigId variable was of type “Oro\Bundle\EntityConfigBundle\Config\Id\FieldConfigId” class, but now when this class want to validate each files in my file collection field $fieldConfigId will be a instance of “Oro\Bundle\EntityConfigBundle\Config\Id\EntityConfigId” class which has no “getFieldType” method and this cause the problem.

with more debuging i realized the only diference between these two validation is $fieldName, when i used a simple file field the $fieldName variable in ConfigFileValidator was name of my field in my entity but when i used a file collection filed, my field name was 0 (it used index to set field name of each file field).

so i discovered in this method of “Oro\Bundle\EntityConfigBundle\Provider\ConfigProvider” class :

PHP

public function getConfig($className, $fieldName = null) { if ($className) { $className = $this->getClassName($className); } if ($fieldName) { return $this->configManager->getFieldConfig($this->scope, $className, $fieldName); } elseif ($className) { return $this->configManager->getEntityConfig($this->scope, $className); } else { return $this->configManager->createEntityConfig($this->scope); } }

1 2 3 4 5 6 7 8 9 10 11 12 13 14

public function getConfig($className, $fieldName = null)     {         if ($className) {             $className = $this->getClassName($className);         }           if ($fieldName) {             return $this->configManager->getFieldConfig($this->scope, $className, $fieldName);         } elseif ($className) {             return $this->configManager->getEntityConfig($this->scope, $className);         } else {             return $this->configManager->createEntityConfig($this->scope);         }     }

when the field name is a valid field name in line 7 of above code it will go to line 8 and a FieldConfigId instance will be returned but when a file in collection is validating and its field name is 0 it fail at line 7 if and because className it valid it will go to line 10 and an instance of EntityConfigId class will be returned.

how can i solve this problem? is there any better way to do this job?

To work with files it’s recommended to use the appropriate migration extension:
Oro\Bundle\AttachmentBundle\Migration\Extension\AttachmentExtension

See https://github.com/oroinc/platform/blob/master/src/Oro/Bundle/AttachmentBundle/readme.md
