Dispaly Blob image from database using Symfony Twig
I am trying to display images for each blog post. I have them set up so that it is displaying the blog name, excerpt and published date, but I am struggling to get the images which I have stored as Blobs. I have attached my code, which is in 3 parts: the entity, which has set and get variables; the index.html.twig file, which is the front end (how I am displaying the image); and the post.orm.yml file, which is to set the type of item the image is, ie, BLOB.
Post entity
/**
* Set image
*
* @param /post/blob $image
*
* @return Post
*/
public function setimage($image)
{
$this->image = $image;
return $this;
}
/**
* Get image
*
* @return post/blob
*/
public function getimage()
{
return $this->image;
}
index.html.twig
{{post.image}}
post.orm.yml
ShannonBlogBundleEntityPost:
type: entity
table: null
repositoryClass: ShannonBlogBundleRepositoryPostRepository
id:
id:
type: integer
id: true
generator:
strategy: AUTO
fields:
title:
type: string
length: '255'
body:
type: text
publishedAt:
type: datetime
column: published_at
image:
type:image
lifecycleCallbacks: { }
postcontroller.php
public function imageAction($id) { $image = $this->getDoctrine()->getRepository('ShannonBlogBundle:Image')->findOneBy(array('id'=> $id));
return $this->render('index.html.twig', array('image' => $image)); } } public function imageAction($id) { $image = $this->getDoctrine()->getRepository('ShannonBlogBundle:Image')->findOneBy(array('id'=> $id));
return $this->render('index.html.twig', array('image' => $image)``); }
您需要使用base64编码您的图像，并将其嵌入到HTML中：
<img src="data:image/png;base64,{{ imageBase64 }}" />
