php - Rename multiple file upload codeigniter -


i want rename files during uploading process. i'm uploading 3 files @ single time. frontend code 

<form> <input type="file" class="form-control" name="photo_1"> <input type="file" class="form-control" name="pan_1"> <input type="file" class="form-control" name="add_1"> </form>

my code in controller following

function upload(){     $this->upload_file('photo_1');      $this->upload_file('pan_1');      $this->upload_file('add_1'); } function upload_file($field_name)     {          //$ext = substr( strrchr($_files[$field_name]['name'], '.'), 1);         //$new_name = $types.'_'.$numb.'_dev_.'.$ext;         $config['file_name']            = $_files[$field_name]['name'];         $config['upload_path']          = './uploads/';         $config['allowed_types']        = 'jpeg|jpg|png';        // $config['max_size']             = 100;          $this->load->library('upload', $config);          if ( ! $this->upload->do_upload($field_name))         {             return array('error' => $this->upload->display_errors());          }         else         {             $data = array('upload_data' => $this->upload->data());          }     }

but i' getting same name each file increment. like photo_1, photo_11, photo_12. want file name photo_sometext_1

any appreciated

problem here $config['file_name'] = $_files[$field_name]['name'];. need pass desired file name.

or

good approach create encrypt_name each file. way codeigniter create random name each file uploaded.

see https://www.codeigniter.com/userguide3/libraries/file_uploading.html#preferences document see available options.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto
