Hi!

I need to set a constant value to one or more fields, but i can't do it.
This is my code:

public function PortalesPropiedades()

{

if (isset($_GET['IdPropiedad']))

$_SESSION['IdPropiedad'] = $_GET['IdPropiedad'];

$this->grocery_crud->set_table('propiedadesportales');

$this->grocery_crud->where('IdPropiedad',$_SESSION['IdPropiedad']);

$this->grocery_crud->set_relation('IdPortal','portales','Portal');

$this->grocery_crud->columns('IdPortal','URL');

$this->grocery_crud->required_fields('IdPortal','URL');

$this->grocery_crud->display_as('IdPortal','Portal');

$this->grocery_crud->callback_before_insert(array($this,'PortalesPropiedadesInsert'));

$output = $this->grocery_crud->render();

$this->PortalesPropiedadesOutput($output);

}

function PortalesPropiedadesInsert($post_array) {

$post_array['idpropiedad'] = $_SESSION['IdPropiedad'];

return $post_array;

} 

function PortalesPropiedadesOutput($output = null)

{

$this->load->view('vista_iframe.php',$output);   

}

If you are trying to set session data you would do well to look at the Session class in the Codeigniter docs.

Thanks!, but is possible to insert a constant value?, another way to do that?
Thanks!

I don't know if I understood your question correctly, but do you need to have a constant default value on some of your input field?
If that's the case I would just have a callback_add_field call a function to change my input to readonly and assing the value I want to it.

Something like this:

$crud->callback_add_field('FIELD_NAME',array($this,'my_callback_function'));



function my_callback_function()

{

	return '<input type="text" readonly="readonly" value="VALUE_FROM_SESSION" name="field_name">';

}

If you wish you can use also a hidden field.

Check the docs for callback_add_field:

I hope this helps.
