php - How to exclude a form file field on $this->save()? -


when user created upload file.

i want edit user, but, when save , not select file, in other words, wants keep original, error:

sql query: update `societario`.`attorneys` set `nome` = 'teste', `empresa` = 'sotreq', `filial` = 'matriz', `unidade` = 'energia', `alcada` = 'até 50.000', `validade` = '', `arquivo` = array `societario`.`attorneys`.`id` = '42'

if user dont select file, want save dont $this->attorney->data['attorney']['arquivo']

my edit.php

function edit($id = null) {        $this->attorney->id = $id;     $this->set('poderes',$this->attorney->power->find('list', array('fields' => 'resumo')));           if ($this->request->is('get')) {             $this->request->data = $this->attorney->read();         } else {              if ($this->attorney->save($this->request->data)) {              $targetfolder = 'societario/app/webroot/uploads/'; // relative root             $tempfile = $this->request->data['attorney']['arquivo']['tmp_name'];             $targetpath = $_server['document_root'] . $targetfolder;             $targetfile = rtrim($targetpath,'/') . '/' . $this->request->data['attorney']['arquivo']['name'];;             move_uploaded_file($tempfile,$targetfile);             $this->attorney->updateall(              array('arquivo' => "'".$this->request->data['attorney']['arquivo']['name'] ."'"),             array('id' => $id));                  $this->session->setflash('usuário editado com sucesso!', 'default', array('class' => 'flash_sucess'));             $this->redirect(array('action' => 'usuarios'));     } }  }

if try upload file isn't working either. same error.

first, exclude field, unset key in array, before call save:

unset($this->attorney->data['attorney']['arquivo']);

second, file uploads, should consider using plugin out - save world of pain! use https://github.com/josegonzalez/upload
