Layout pre_process Issue

"Similarly, you can overwite the Base_layout classes fields() method to return the fields for your layout:"

But i can't found the Base Layout file to extend. can anyone help?

That's a typo and should be the Fuel_layout.php. Often we'll create a Base_layout class that extends the Fuel_layout and inherit from that which is where that typo came from. I'll make a fix for the 1.3 documentation.

Thanks. I am trying to inherit Fuel_layout

When i inherit Fuel_layout, my view page become blank. Is anything wrong in the config? The path should be correct.

[MY_fuel_layouts.php]
$config['layouts']['main'] = array(
'file' => $config['layouts_folder'].'/main',
'label' => 'Main',
'class' => 'Main_layout',
'filepath' => 'libraries/_layout',
'filename' => 'Main_layout.php',


'fields' => array(
'Header' => array('type' => 'fieldset', 'label' => 'Header', 'class' => 'tab'),
'page_title' => array('label' => lang('layout_field_page_title')),
'meta_description' => array('label' => lang('layout_field_meta_description')),
'meta_keywords' => array('label' => lang('layout_field_meta_keywords')),
'Body' => array('type' => 'fieldset', 'label' => 'Body', 'class' => 'tab'),
'heading' => array('label' => lang('layout_field_heading')),
'body' => array('label' => lang('layout_field_body'), 'type' => 'textarea', 'description' => lang('layout_field_body_description')),
'body_class' => array('label' => lang('layout_field_body_class')),
)
);


[Main_Layout.php]
require_once(FUEL_PATH.'libraries/Fuel_layouts.php');
class Main_layout extends Fuel_layouts {
function fields()
{
$fields = parent::fields($include);

return $fields;
}

function pre_process($vars)
{
return $vars;
}
}

If you use the class, you can include your fields array in that method instead of in the configuration. Also, there is an $include variable that doesn't look to be defined:
$fields = parent::fields($include);
