In order to set your Genesis Grid Loop 'features', which are the number of posts that will show at the top of the page when using the Grid Loop, to one specific category or categories and the non-features or grid posts to another category or set of categories, you will need to adjust your grid_loop_helper function.
Here is a simple way of displaying posts via categories via the Grid loop calling genesis_grid_loop() twice.
[php highlight="15-16, 29-30, 33-39"]function child_grid_loop_helper() {
global $paged;
if ( function_exists( 'genesis_grid_loop' ) ) {
//set featured grid_args
$grid_args_featured = array(
'features' => 1,
'feature_image_size' => 'child_full',
'feature_image_class' => 'aligncenter post-image',
'feature_content_limit' => 100,
'grid_image_size' => 'child_thumb',
'grid_image_class' => 'aligncenter post-image',
'grid_content_limit' => 0,
'more' => '',
'posts_per_page' => 1,
'post_type' => 'books_fbd',
'cat' => '8',
'paged' => $paged
);
//set non-featured grid_args
$grid_args_rest = array(
'features' => 0,
'feature_image_size' => 'child_full',
'feature_image_class' => 'aligncenter post-image',
'feature_content_limit' => 100,
'grid_image_size' => 'child_thumb',
'grid_image_class' => 'aligncenter post-image',
'grid_content_limit' => 0,
'more' => '',
'posts_per_page' => 4,
'post_type' => 'books_fbd',
'cat' => '7',
'paged' => $paged
);
//assuming that features won't go beyond 1 page
if ( ($grid_args_featured['paged'] > 1) || ($grid_args_past['paged'] > 1) )
genesis_grid_loop( $grid_args_rest ); //do not show featured after page 1
else {
genesis_grid_loop( $grid_args_featured );
genesis_grid_loop( $grid_args_rest );
}
} else {
genesis_standard_loop();
}
} [/php]
However, I have posted on the StudioPress forums, which creates another argument for 'features_cat' suggesting some edits for the genesis_grid_loop() function.
