與Grocery Crud的多個上傳

Question

我正在與雜貨店的後端部分操作crud，我需要上傳5張圖片（其中3個具有相同的寬度和高度，另外2個具有不同大小），但是，當我嘗試用set_field_upload上傳，所有文件都上傳一個尺寸。我預計diferents大小。我試過GD2（Codeigniter版本），但我不知道grocery_crud是否可以做到這一點。

public function marcas(){ 

     $this  -> load    -> view('header'); 
     $this  -> load    -> view('leftbar'); 
     $this  -> grocery_crud  -> set_theme('datatables');   
     $this  -> grocery_crud  -> set_table('marcas'); 
     $this  -> grocery_crud  -> set_subject('Marcas'); 
     $this  -> grocery_crud  -> columns('nombre','descripcion','texto','logo'); 
     $this  -> grocery_crud  -> set_relation('id_tipo_marca','tipo_marcas','nombre'); 
     $this  -> grocery_crud  -> display_as('id','ID'); 
     $this  -> grocery_crud  -> display_as('id_tipo_marca','Tipo Marca'); 
     $this  -> grocery_crud  -> display_as('nombre','Nombre'); 
     $this  -> grocery_crud  -> display_as('descripcion','Descripcion'); 
     $this  -> grocery_crud  -> display_as('texto','Texto'); 
     $this  -> grocery_crud  -> display_as('link','Link'); 
     $this  -> grocery_crud  -> display_as('logo','Logo'); 
     $this  -> grocery_crud  -> set_field_upload('logo','../img'); 
     $this  -> grocery_crud  -> callback_after_upload(array($this, 'example_callback_after_upload_logo')); 
     $this  -> grocery_crud  -> display_as('imagen','Imagen Grande'); 
     $this  -> grocery_crud  -> display_as('imagen2','Imagen Pequeña 1'); 
     $this  -> grocery_crud  -> display_as('imagen3','Imagen Pequeña 2'); 
     $this  -> grocery_crud  -> display_as('imagen4','Imagen Pequeña 3'); 
     $this  -> grocery_crud  -> set_field_upload('imagen','../img/grande'); 
     $this  -> grocery_crud  -> callback_after_upload(array($this, 'example_callback_after_upload_grande')); 
     $this  -> grocery_crud  -> set_field_upload('imagen2','../img/thumb'); 
     $this  -> grocery_crud  -> set_field_upload('imagen3','../img/thumb'); 
     $this  -> grocery_crud  -> set_field_upload('imagen4','../img/thumb'); 
     $this  -> grocery_crud  -> callback_after_upload(array($this, 'example_callback_after_upload_thumb')); 
     $output  = $this    -> grocery_crud   -> render(); 
     $this  -> _example_output($output); 
     $this  -> load    -> view('footer');  
} 

function example_callback_after_upload_grande($uploader_response,$field_info,$files_to_upload){ 
    $this -> load -> library ('image_moo'); 
    $file_uploaded = $field_info->upload_path.'/'.$uploader_response[0]->name; 
    $this -> image_moo -> load($file_uploaded) ->resize_crop(317,140)->save($file_uploaded, true); 
    return true; 
var_dump($uploader_response);die; 

function  example_callback_after_upload_logo($uploader_response,$field_info,$files_to_upload){ 
    $this -> load -> library ('image_moo'); 
    $file_uploaded = $field_info->upload_path.'/'.$uploader_response[0]->name; 
    $this -> image_moo -> load($file_uploaded) ->resize(125,83)- >save($file_uploaded, true); 
    return true; 
var_dump($uploader_response);die; 
} 

function example_callback_after_upload_thumb($uploader_response,$field_info,$files_to_upload){ 
    $this -> load -> library ('image_moo'); 
    $file_uploaded = $field_info->upload_path.'/'.$uploader_response[0]->name; 
    $this -> image_moo -> load($file_uploaded) ->resize_crop(317,140)->save($file_uploaded, true); 
    return true; 
var_dump($uploader_response);die; 

}

這是我的解決方案。

public function marcas(){ 
     ... 
     $this->grocery_crud->callback_after_upload(array($this, 'reImage_callback_after_upload')); 
     ... 
    } 

public function reImage_callback_after_upload($uploader_response, $field_info, $files_to_upload) { 
    $this -> load -> library('image_moo'); 
    switch ($field_info->field_name) { 
     case 'logo': 
      $file_uploaded = $field_info -> upload_path . '/' . $uploader_response[0] -> name; 
      $this -> image_moo -> load($file_uploaded) -> resize_crop(20, 20) -> save($file_uploaded, true); 
      return true; 
      break; 
     case 'imagen': 
      $file_uploaded = $field_info -> upload_path . '/' . $uploader_response[0] -> name; 
      $this -> image_moo -> load($file_uploaded) -> resize_crop(30, 30) -> save($file_uploaded, true); 
      return true; 
      break; 
     case 'imagen2': 
      $file_uploaded = $field_info -> upload_path . '/' . $uploader_response[0] -> name; 
      $this -> image_moo -> load($file_uploaded) -> resize_crop(40, 40) -> save($file_uploaded, true); 
      return true; 
      break; 
     case 'imagen3': 
      $file_uploaded = $field_info -> upload_path . '/' . $uploader_response[0] -> name; 
      $this -> image_moo -> load($file_uploaded) -> resize_crop(50, 50) -> save($file_uploaded, true); 
      return true; 
      break;  
     case 'imagen4': 
      $file_uploaded = $field_info -> upload_path . '/' . $uploader_response[0] -> name; 
      $this -> image_moo -> load($file_uploaded) -> resize_crop(60, 60) -> save($file_uploaded, true); 
      return true; 
     break; 
     default: 
      return false; 
      break; 
    } 
}
