I tried different solutions and now I working with walker nav menu.
This is the code:
// Class to insert div and page into nav menu (not working yet)
class description_walker extends Walker_Nav_Menu
{
function start_el(&$output, $item, $depth, $args)
{
global $wp_query;
$indent = ( $depth ) ? str_repeat( "\t", $depth ) : '';
$class_names = $value = '';
$classes = empty( $item->classes ) ? array() : (array) $item->classes;
$class_names = join( ' ', apply_filters( 'nav_menu_css_class', array_filter( $classes ), $item ) );
$class_names = ' class="'. esc_attr( $class_names ) . '"';
$output .= $indent . '<li id="menu-item-'. $item->ID . '"' . $value . $class_names .'>';
$attributes = ! empty( $item->attr_title ) ? ' title="' . esc_attr( $item->attr_title ) .'"' : '';
$attributes .= ! empty( $item->target ) ? ' target="' . esc_attr( $item->target ) .'"' : '';
$attributes .= ! empty( $item->xfn ) ? ' rel="' . esc_attr( $item->xfn ) .'"' : '';
$attributes .= ! empty( $item->url ) ? ' href="' . esc_attr( $item->url ) .'"' : '';
// $prepend = '<strong>';
// $append = '</strong>';
$description = empty( $item->description ) ? '<div class="dropEverything-page"><div class="dropEverything-row">'.esc_attr( $item->description ).'</div></div>' : '';
if($depth != 0)
{
$description = $append = $prepend = "";
}
$item_output = $args->before;
$item_output .= '<a'. $attributes .'>';
$item_output .= $args->link_before .$prepend.apply_filters( 'the_title', $item->title, $item->ID ).$append;
$item_output .= $description.$args->link_after;
$item_output .= '</a>';
$item_output .= $args->after;
$output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );
}
}
I modified this line:
// I need to get the ID of the page and put it into the anchor
$postID = get_page_by_title("Profile")->ID;
$post = get_post(&$postID);
$description = empty( $item->description ) ? '<div class="dropEverything-page"><div class="dropEverything-row">'.esc_attr( $item->description ).'</div></div>' : '';
I need to substitute
esc_attr( $item->description )
with
esc_attr( echo apply_filters("the_content", $post->post_content) )
but the website return me a blank page.
Any suggestion?
thanks
