除了WordPress预构建的助行器外,您还可以使用其他助行器。
将此添加到您的函数中。主题中的php文件:
class Clean_Nav_Walker extends Walker {
var $tree_type = array( \'post_type\', \'taxonomy\', \'custom\' );
var $db_fields = array( \'parent\' => \'menu_item_parent\', \'id\' => \'db_id\' );
function start_lvl(&$output, $depth) {
$indent = str_repeat("\\t", $depth);
$output .= "\\n$indent<ul class=\\"sub-menu\\">\\n";
}
function end_lvl(&$output, $depth) {
$indent = str_repeat("\\t", $depth);
$output .= "$indent</ul>\\n";
}
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;
$classes = in_array( \'active\', $classes ) ? array( \'active\' ) : array();
$class_names = join( \' \', apply_filters( \'nav_menu_css_class\', array_filter( $classes ), $item, $args ) );
$class_names = strlen( trim( $class_names ) ) > 0 ? \' class="\' . esc_attr( $class_names ) . \'"\' : \'\';
$id = apply_filters( \'nav_menu_item_id\', \'\', $item, $args );
$id = strlen( $id ) ? \' id="\' . esc_attr( $id ) . \'"\' : \'\';
$output .= $indent . \'<li\' . $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 ) .\'"\' : \'\';
$item_output = $args->before;
$item_output .= \'<a\'. $attributes .\'>\';
$item_output .= $args->link_before . apply_filters( \'the_title\', $item->title, $item->ID ) . $args->link_after;
$item_output .= \'</a>\';
$item_output .= $args->after;
$output .= apply_filters( \'walker_nav_menu_start_el\', $item_output, $item, $depth, $args );
}
function end_el(&$output, $item, $depth) {
$output .= "</li>\\n";
}
}
然后确保在调用时指定新的自定义Walker
wp_nav_menu()
.
<?php
$walker = new Clean_Nav_Walker();
$attr = array( \'theme_location\' => \'quicklink\', \'walker\' => $walker);
wp_nav_menu( $attr );
?>
