Hi all,
First thanks for this great effort.
 
i am new in grucery crud library and i am facing a problem that i build a site that has many images so i want to upload images in different folders for example a folder for every day upload so i write this code
 
$crud->set_field_upload('image','assets/uploads/fashion-media/'.date('Y').'/'.date('m').'/'.date('d'));
 
and i made a function to create the destination folder if it is not exists
the upload works fine but when i tried to edit a record i have image preview error because it uses the the upload path that found in set_file_upload and not uses the last file upload destination
 
so i want to pass the file url to the edit record page
 
can any one help ?

all i want to do is to divide my uploads into more than one folder because i have more uploads and i don't want to put them all in the same folder, can any one tell me how to do that ?

 

this is my code that has an issue in image url while editing the record

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Designer extends MY_Controller {

  public function index(){    
    // CRUD table
    $this->load->model('designer_model');
    $this->load->helper('crud');
    $this->load->helper('my_dir_helper');

    $crud = generate_crud('designers');

    if($this->uri->segment(4) && $crud->getState() == 'success'){
      redirect('crop/image_crop/designer/'.$this->uri->segment(4));
    }
    
    $crud->columns('title', 'description', 'category_id', 'media_count', 'image');
    $crud->display_as('media_count', 'Media Count')
    ->display_as('category_id', 'Category');

    // sert relation
    $crud->set_relation('category_id', 'designer_categories', 'title');

    $crud->required_fields('title', 'category_id', 'image');

    $crud->field_type('slug', 'invisible');
    $crud->field_type('media_count', 'invisible');
    $crud->field_type('created', 'invisible');
    $crud->field_type('updated', 'invisible');
    $crud->field_type('views', 'invisible');
    $crud->field_type('likes', 'invisible');
    $crud->field_type('image_path', 'invisible');

    $crud->set_lang_string('form_update_changes','Update designer')
         ->set_lang_string('form_update_and_go_back','Update and go to crop image')
         ->set_lang_string('form_save_and_go_back','Save and go to crop image')
         ->set_lang_string('form_save','Save designer');

    // prepare for file upload
    mkdir_if_not_exists('assets/uploads/fashion-media/'.date('Y').'/'.date('m').'/'.date('d'));
    $crud->set_field_upload('image','assets/uploads/fashion-media/'.date('Y').'/'.date('m').'/'.date('d'));

    // callback functions
    $crud->callback_before_insert(array($this, 'callback_before_create_designer'));
    $crud->callback_before_update(array($this, 'callback_before_update_designer'));
    $crud->callback_after_upload(array($this, 'callback_after_upload_designer'));
    $crud->callback_column('image',array($this,'callback_image_url'));

    $this->mTitle = "Designers";
    $this->mViewFile = '_partial/crud';
    $this->mViewData['crud_data'] = $crud->render();
  }

  /**
   * Add created and updated fields on insert
   */
  public function callback_before_create_designer($post_array){
    $post_array['slug'] = url_title($post_array['title'], 'dash', TRUE);
    $post_array['image_path'] = 'assets/uploads/fashion-media/'.date('Y').'/'.date('m').'/'.date('d');
    $post_array['created'] = date('Y-m-d H:i:s');
    $post_array['updated'] = date('Y-m-d H:i:s');
    return $post_array;
  }

  /**
   * Change updated field with current time on update
   */
  public function callback_before_update_designer($post_array){
    $post_array['slug'] = url_title($post_array['title'], 'dash', TRUE);
    $post_array['updated'] = date('Y-m-d H:i:s');
    return $post_array;
  }

  public function callback_image_url($value, $row){
    return '<a href="'.base_url($row->image_path.'/'.$row->image).'" class="image-thumbnail"><img src="'.base_url($row->image_path.'/athumb_'.$row->image).'" height="50px"></a>';
  }

  /**
   * callback function to create automatic thumb after uploading the image
   */
  public function callback_after_upload_designer($uploader_response,$field_info, $files_to_upload){
    $this->load->library('image_moo');
    //Is only one file uploaded so it ok to use it with $uploader_response[0].
    $file_uploaded = 'assets/uploads/fashion-media/'.date('Y').'/'.date('m').'/'.date('d') .'/'.$uploader_response[0]->name;
    if($this->image_moo->load($file_uploaded)->resize_crop(323,283)->save_pa('athumb_')){
      return true;
    }else{
      return false;
    }
  }

}

when you edit a designer that his image uploaded any day before today i get preview error (you can check image above in the topic)

well that is bound to happen  because you are uploading it correctly but presrving it the wrong way.

instead you need to write a callback to move the uploaded file to the required directory. Post that is done - update the record with the path (ex: the date) ... thats the only additional path required..

by default your upload path should have been set to the folder just before the date.

 

So when u edit / list - it will append the date and the image name in the path - thats it.. you done with..

 

Happy GCing:)

Many thanks for your reply.

 

my solution

i checked the current state and on edit i saved the current record image path into a session and use this path to set the upload file and on add state i used the default upload path that works for me .. check the code below

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Designer extends MY_Controller {

  public function index(){    
    // CRUD table
    $this->load->model('designer_model');
    $this->load->helper('crud');
    $this->load->helper('my_dir_helper');

    $crud = generate_crud('designers');

    // state and state info
    $state = $crud->getState();
    $state_info = $crud->getStateInfo();

    // save current designer image name in a session to update it in the db if it is changed
    if($state == 'edit' && $this->uri->segment(4)){
      $current = $this->designer_model->get($this->uri->segment(4));
      $this->session->set_userdata('last_image_name', $current['image']);
      $this->session->set_userdata('last_image_path', $current['image_path']);
    }
    
    // redirect to manual crop image from page
    if($state == 'success' && $this->uri->segment(4)){
      redirect('crop/image_crop/designer/'.$state_info->primary_key);
    }
    
    $crud->columns('title', 'description', 'category_id', 'media_count', 'image', 'move_up_down');
    $crud->display_as('media_count', 'Media Count')
    ->display_as('category_id', 'Category');

    // sert relation
    $crud->set_relation('category_id', 'designer_categories', 'title');

    $crud->required_fields('title', 'category_id', 'image');

    $crud->field_type('slug', 'invisible');
    $crud->field_type('media_count', 'invisible');
    $crud->field_type('created', 'invisible');
    $crud->field_type('updated', 'invisible');
    $crud->field_type('views', 'invisible');
    $crud->field_type('likes', 'invisible');
    $crud->field_type('image_path', 'invisible');
    $crud->field_type('priority', 'invisible');

    // designer ordering
    $crud->callback_column('move_up_down', array($this, 'populate_up_down'));
    $crud->order_by('priority', 'desc');
    $this->session->set_userdata('callableAction', site_url(). '/designer/updatePosition/designers');
    $this->session->set_userdata('primary_key', 'id');
    $crud->set_js("backend.php/designer/dragdrop_js");

    $crud->set_lang_string('form_update_changes','Update designer')
         ->set_lang_string('form_update_and_go_back','Update and go to crop image')
         ->set_lang_string('form_save_and_go_back','Save and go to crop image')
         ->set_lang_string('form_save','Save designer');

    // prepare for file upload
    mkdir_if_not_exists('assets/uploads/fashion-media/'.date('Y').'/'.date('m').'/'.date('d'));

    // set file upload path according to the current controller state
    if($state == 'add' || $state == 'upload_file'){
      $crud->set_field_upload('image','assets/uploads/fashion-media/'.date('Y').'/'.date('m').'/'.date('d'));
    }elseif($state == 'edit' || $state == 'delete_file'){
      $crud->set_field_upload('image', $this->session->userdata('last_image_path'));

      // delete the auto and manual thumb on deleting the original file
      if($state == 'delete_file') {
        // auto thumb
        if(file_exists($this->session->userdata('last_image_path') . '/athumb_' . $this->session->userdata('last_image_name'))){
          unlink($this->session->userdata('last_image_path') . '/athumb_' . $this->session->userdata('last_image_name'));
        }
        
        // manual thumb
        if(file_exists($this->session->userdata('last_image_path') . '/mthumb_' . $this->session->userdata('last_image_name'))){
          unlink($this->session->userdata('last_image_path') . '/mthumb_' . $this->session->userdata('last_image_name'));
        }
      }

    }else{
      $crud->set_field_upload('image','assets/uploads/fashion-media/'.date('Y').'/'.date('m').'/'.date('d'));
    }

    // callback functions
    $crud->callback_before_insert(array($this, 'callback_before_create_designer'));
    $crud->callback_after_insert(array($this, 'callback_after_create_designer'));
    $crud->callback_before_delete(array($this, 'callback_before_delete_designer'));
    $crud->callback_before_update(array($this, 'callback_before_update_designer'));
    $crud->callback_after_upload(array($this, 'callback_after_upload_designer'));
    $crud->callback_column('image',array($this,'callback_image_url'));

    $this->mTitle = "Designers";
    $this->mViewFile = '_partial/crud';
    $this->mViewData['crud_data'] = $crud->render();
  }
}
?>

again thanks for this awesome library it saved my time
