symfony對象圖像多對多

Question

我有一個數據庫，需要有一個對象的多個圖像。 在列表視圖中，我看到了多個圖像，但它出現在texte中，我需要有圖像！

這是我的產品實體（一個produc很多圖片）

/** 
* @param ShowMapper $showMapper 
*/ 
protected function configureShowFields(ShowMapper $showMapper) 

{ 

    $showMapper 
     ->with('PRODUCT DESCRIPTION', array('class' => 'col-md-7')) 
     ->add('name') 
     ->add('country') 
     ->add('descriptionshortnat', null, array('label' => 'Description short (national)')) 
     ->add('descriptionlongnat', null, array('label' => 'Description long (national)')) 
     ->add('descriptionshorten', null, array('label' => 'Description short (english)')) 
     ->add('descriptionlongen', null, array('label' => 'Description long (english)')) 
     ->add('created') 
     ->add('updated') 
     ->end() 

     ->with('PICTURES', array('class' => 'col-md-5')) 
     ->add('image', 'string' , array("template"=>"AdminBundle::Admin/list_types/image.html.twig")) 
     ->end() 

     ->with('CLASSIFICATION', array('class' => 'col-md-5')) 
     ->add('category') 
     ->add('preservation', null, array('label' => 'Preservation method')) 
     ->add('population', null, array('label' => 'Population target')) 
     ->add('innovation') 
     ->add('timeframe', null, array('label' => 'Comsumer timeframe')) 
     ->add('component') 
     ->end() 
     ->with('PARTNERS', array('class' => 'col-md-5')) 
     ->end()    
     ->with('COMPETITION', array('class' => 'col-md-5')) 
     ->add('contact', 'sonata_type_model', array('required' => false, 'multiple' => true,'label' => 'Student team')) 
     ->add('organisation', 'sonata_type_model', array('required' => false)) 
     ->add('competition', 'sonata_type_model', array('required' => false, 'multiple' => true)) 
     ->end() 



    ; 
} 

}

列表映射器，這是我枝杈我的 '形象'

{% extends 'SonataAdminBundle:CRUD:base_list_field.html.twig' %} 

{% block field %} 
    <a href="{{ asset('uploads/documents/') }}{{ value|nl2br }}"><img class="admin-list-preview" src="{{ asset('uploads/documents/') }}{{ value|nl2br }}"/></a> 
{% endblock %}

     return; 
    } 

    // we use the original file name here but you should 
    // sanitize it at least to avoid any security issues 

    // move takes the target directory and target filename as params 
    $this->getFile()->move(

    // set the path property to the path where you've saved the file 
    $this->setFichier($this->getFile()->getClientOriginalName()); 

    // clean up the file property as you won't need it anymore 
    $this->setFile(null); 






}

     if(is_file($file)) 
     { 
      unlink($file); 
     } 
    } 

} 

public function getAbsolutePath() 
{ 
    return null === $this->getFichier() 
     ? null 
     : $this->getUploadRootDir().'/'.$this->getFichier(); 

} 

public function getWebPath() 
{ 
    return null === $this->getFichier() 
     ? null 
     : $this->getUploadDir().'/'.$this->getFichier(); 


} 

protected function getUploadRootDir() 
{ 
    // the absolute directory path where uploaded 
    // documents should be saved 
    return __DIR__.'/../../../web/'.$this->getUploadDir(); 

} 

protected function getUploadDir() 
{ 
    // get rid of the __DIR__ so it doesn't screw up 
    // when displaying uploaded doc/image in the view. 
    return 'uploads/documents'; 

    } 

}

Answer 1

如果你不會看到你的形象 - 使用這種結構：

{{ asset('uploads/documents/' ~ object.image) }} 
uploads/documents/ - folder to you directory with images. 
object.image - image name (twig variable) 

例如用SonataAdminBundle

{% for image in object.image %} 
    <img class="admin-list-preview" src="{{ asset('uploads/documents/' ~ image) }}"/> 
{% end for %}
