php - File uploads in Symfony 2 using sonata-project -

i trying upload image in symfony 2 backend using sonata-project. challenge i'm facing right image inserted database table , uploaded specified path. have given upload folder writeable permissions. not sure missing here steps have taken.

class homeenumerate {  // ... protected function getuploaddir() {     return 'uploads/houses'; }  protected function getuploadrootdir() {     return __dir__.'/../../../../web/'.$this->getuploaddir(); }  public function getwebpath() {     return null === $this->house_picture ? null :   $this->getuploaddir().'/'.$this->house_picture; }  public function getabsolutepath() {     return null === $this->house_picture ? null : $this->getuploadrootdir().'/'.$this->house_picture; } 

}

i have edited homeenumerate.orm.yml have put in lifecyclecallbacks:

lifecyclecallbacks:     prepersist: [ preupload, setcreatedatvalue, setexpiresatvalue ]     preupdate: [ preupload, setupdatedatvalue ]     postpersist: [ upload ]     postupdate: [ upload ]     postremove: [ removeupload ] 

after generate:entities have edited homeenumerate entity

class job { // ...  /**  * @orm\prepersist  */ public function preupload() {      if (null !== $this->file) {          $this->logo = uniqid().'.'.$this->file->guessextension();      } }  /**  * @orm\postpersist  */ public function upload() {     if (null === $this->file) {         return;     }      // if there error when moving file, exception     // automatically thrown move(). prevent     // entity being persisted database on error     $this->file->move($this->getuploadrootdir(), $this->logo);      unset($this->file); }  /**  * @orm\postremove  */ public function removeupload() {     if(file_exists($file)) {         if ($file = $this->getabsolutepath()) {             unlink($file);         }     }     } 

}

can please me uploading files db , folder path.

you should implement callbacks in admin class, too. actually, sonataadminbundle has a cookbook recipe on handling file uploads. hopefully, should answer of questions.
