hi,
i have a table with 2 fields, the first is the id that references another table and is not unique, while the second is the name of an image.
my primary is both of them.

primary key ( id, images)

i need to add and delete entry so i tried this code:

//Carico la libreria CRUD

   $this->load->library('grocery_CRUD');

   $crud = new grocery_CRUD();

  

  

   $crud->set_table('immagini');

   $crud->required_fields('immagine');

   $crud->set_relation('id','cani','nome');

   $crud->set_field_upload('immagine','assets/uploads/files');

		 $output = $crud->render();

but when i try to delete one row the system delete all the entry with the same id...i need to handle this operation because that's not rigth for me, i need that only the selected row is deleted...can i handle the delete button?

i've already try with getState:

state = $crud->getState();

	  $state_info = $crud->getStateInfo();

  

    if($state == 'delete')

	  {

		  $primary_key = $state_info->primary_key;

		  //Do your awesome coding here.

		  echo "handle";

	  }

but it doesn't work...

Yes you can handle the delete with a callback_escape_delete . You can see an example at: http://www.grocerycrud.com/crud/function_name/callback_escape_delete

Thanks!

This is my update code:

function gestioneimmagini(){

   $info_menu['corrente'] = 3;

  

   //Carico la libreria CRUD

   $this->load->library('grocery_CRUD');

   $crud = new grocery_CRUD();

  

  

   $crud->set_table('immagini');

   $crud->required_fields('immagine');

   $crud->set_relation('id','cani','nome');

   $crud->set_field_upload('immagine','assets/uploads/files');

   $crud->callback_escape_delete(array($this,'cancella_riga'));



    $output = $crud->render();

		

			

	$this->load->view('admin/header',$info_menu);

	$this->load->view('admin/gestione_razze',$output);

	$this->load->view('admin/footer');

  

  }



  public function cancella_riga($primary_key){

  

  }

in my table i have a primary_key formed by two attribute, how can i handle it now?
I need to create a query like

DELETE FROM immagini WHERE id='$id' AND name='$nome'

If you have the id why to have the name? A primary key is unique always so you will not have any problem with a simple callback_escape_delete
