Hello again Johnny!

It's been quite while, huh? What a incredible tool you've created here. Thanks man!

Now... a question: How do I create a hidden field that is not part of any database and belongs to no table at all?
Let me explain... I added an action with add_action which calls another CRUD passing the ID through the link, where I retrieve it with GET. Now, that only works once. So, if I add or edit some item on my list, that filter is lost. I thought that I could keep it creating a hidden field. But, when I tried to create it with add_fields or edit_fields, I get this error:


[b] A PHP Error was encountered[/b]

Severity: Notice
Message: Undefined index: filtra_apontamento
Filename: controllers/titulos.php
Line Number: 70
filtra_apontamento is the hidden field I'm trying to create. Here it is the code:

	  $this->grocery_crud->add_fields('filtra_apontamento');

	  $this->grocery_crud->edit_fields('filtra_apontamento');

	  $this->grocery_crud->field_type('filtra_apontamento', 'hidden', $_GET['filtra_apontamento']);

And there's also another question: How do I use the value of this created field, assuming it is possible to create it, on my filter parameters at

$this->grocery_crud->where('titulo.apontamento_id', <what it goes here?>);

Thanks for any help you may provide.

HI! Show your url for the "add_action".

Hi Victor! Thanks for answering!

I've found an error on

$this->grocery_crud->field_type('filtra_apontamento', 'hidden', $_GET['filtra_apontamento']);

It is instead

$this->grocery_crud->field_type('filtra_apontamento', 'hidden', $_GET['apontamento_id']);

The error is no longer, but I've looked at the source code of my page and found no hidden fields in the code.

Here it is the data you requested

This is the link

    $this->grocery_crud->add_action('Ver Títulos', '/imagens/Document-Copy-icon.png', '', '', array($this,'set_url'));

This is the function that generates the link

  function set_url($primary_key, $row){

   

    return (site_url('titulos/?apontamento_id=' . $row->apontamento_id));

   

  }

You should to use a segment as solution.

for example you have this url to the function:

[quote]
http://my_site.com/c...oller/function/
[/quote]

return (site_url('controller/function/' . $row->apontamento_id));

then:

$this->grocery_crud->where('titulo.apontamento_id', $this->uri->segment(3));

It works perfectly.

Thanks Victor!

This was an elegant solution.
