I have a question with the same scenario as this question, except that it might happen that more than one _ is in the text.
An example;
57b42a0557cdd_Filename_whatever.pdf
How can I omit everything up until the first underscore (including the underscore) to keep the rest like Filename_whatever.pdf
The random uniquifier can be of a different length, but there will always be an underscore between it and the actual filename.
Like in the mentioned question; {{ filename|split('_')[1] }} might work, but what if the actual filename has an underscore?
I want it preferably in twig just for displaying purposes because the complete unique name is used on different parts of the project as well.
As seen in the documentation, split also supports the limit parameter as explode, so you can do :
{{ '57b42a0557cdd_Filename_whatever.pdf' | split('_', 2)[1] }}
{{ '57b42a0557cdd_Filename_what_ever.pdf' | split('_', 2)[1] }}
{{ '57b42a0557cdd_File_name_whatever.pdf' | split('_', 2)[1] }}
Answer：
Another option (assuming that the file is part of an entity) is to write a function on the entity that that returns what you want.
For example;
<?php
namespace AppBundle\Entity;
class MyEntity
{
// ... other attributes
private $hashFileName;
private $cleanFileName;
// other functions
public function getHashFileName()
{
// as per you example; 57b42a0557cdd_Filename_whatever.pdf
return $this->hashFileName;
}
public function getCleanFileName()
{
$withouthash = explode('_', $this->hashFileName,2);
return $withouthash[1];
}
}
Then in your twig file;
{{ myObject.cleanfilename }}
