I a using this code for image removal when i delete the entity
/**
* @ORM\PostRemove()
*/
public function removeUpload()
{
if ($this->filenameForRemove)
{
unlink ( $this->filenameForRemove );
}
}
But the problem is if i don't have the image there then it throws exception like this
Warning: unlink(/home/site/../../../../uploads/50343885699c5.jpeg) [<a href='function.unlink'>function.unlink</a>]: No such file or directory i
Is there any way that if file is not there or directory is not there it should skip this step and still deletes the entity
You can use file_exists
to make sure the file actually exists and is_writable
to make sure you have permission to remove it.
if ($this->filenameForRemove)
{
if (file_exists($this->filenameForRemove) &&
is_writable($this->filenameForRemove))
{
unlink ( $this->filenameForRemove );
}
}
Symfony has introduced the The Filesystem Component. You can check the docs here . It says: The Filesystem component provides basic utilities for the filesystem.
For example you can check if the file path/directory exists before deleting your file like this:
use Symfony\Component\Filesystem\Filesystem;
$filesystem = new Filesystem();
$oldFilePath = '/path/to/directory/activity.log'
if($filesystem->exists($oldFilePath)){
$filesystem->remove($oldFilePath); //same as unlink($oldFilePath) in php
}
