我将为a
菜单中的标签,如have<a href="#example" data-attribute="attribute">CLICK</a>
我知道我必须扩展Walker,但我尝试了好几次(在internet上找到一些代码),但都没有成功。
这里是代码(我还没有尝试插入data-attribute
因为在我开始制作菜单之前。)代码:
/* WALKER */
wp_nav_menu( array(
\'container\' =>false,
\'menu_class\' => \'nav\',
\'echo\' => true,
\'before\' => \'\',
\'after\' => \'\',
\'link_before\' => \'\',
\'link_after\' => \'\',
\'depth\' => 0,
\'walker\' => new description_walker())
);
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 ) ? \'<span>\'.esc_attr( $item->description ).\'</span>\' : \'\';
if($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 );
}
}
这里是错误:
有什么可以帮我的吗?谢谢:)
