Wordpress wp_nav_menu nav > a - php

Question

I'm actually working on a website and i develop a theme.
I've a problem with the wp_nav_menu.
I've a navigation like this :
<nav>
item 1
item 2
item 3
item 4
</nav>
And i would like this menu:
<nav>
item 1
item 2
item 2
item 1
</nav>
if you preferer , add a custom class for each .
Here are the parameters of the current menu. No function in function.php
<?php
$menuParameters = array(
'theme_location' => 'primary',
'container' => false,
'echo' => false,
'items_wrap' => '%3$s',
'depth' => 0,
);
echo strip_tags(wp_nav_menu( $menuParameters ), '<a>' );
?>
Have u got any solution ?
I specify that the classes in the administration > navigation don't work

Answer 1

In your backend go to Appearance -> Menus. In the top right corner there is a tab called Screen Options, there in 'Show advanced menu properties' tick CSS classes, that will enable you to add adittional class to your menu items.

Answer 2

You need the custom nav menu walker to achieve this.
First, you need to remove the <ul>, </ul>, <li>, and </li> tags on the walker,
and then move the css classes to the <a> tag.
Below is the walker i've tried, paste this on functions.php:
class Custom_Walker_Nav_Menu extends Walker_Nav_Menu {
public function start_lvl( &$output, $depth = 0, $args = array() ) {
if ( isset( $args->item_spacing ) && 'discard' === $args->item_spacing ) {
$t = '';
$n = '';
} else {
$t = "\t";
$n = "\n";
}
$indent = str_repeat( $t, $depth );
$output .= "{$n}{$indent}{$n}";
}
public function end_lvl( &$output, $depth = 0, $args = array() ) {
if ( isset( $args->item_spacing ) && 'discard' === $args->item_spacing ) {
$t = '';
$n = '';
} else {
$t = "\t";
$n = "\n";
}
$indent = str_repeat( $t, $depth );
$output .= "{$n}";
}
public function start_el( &$output, $item, $depth = 0, $args = array(), $id = 0 ) {
if ( isset( $args->item_spacing ) && 'discard' === $args->item_spacing ) {
$t = '';
$n = '';
} else {
$t = "\t";
$n = "\n";
}
$indent = ( $depth ) ? str_repeat( $t, $depth ) : '';
$classes = empty( $item->classes ) ? array() : (array) $item->classes;
$classes[] = 'menu-item-' . $item->ID;
$args = apply_filters( 'nav_menu_item_args', $args, $item, $depth );
$class_names = join( ' ', apply_filters( 'nav_menu_css_class', array_filter( $classes ), $item, $args, $depth ) );
$atts = array();
$atts['title'] = ! empty( $item->attr_title ) ? $item->attr_title : '';
$atts['target'] = ! empty( $item->target ) ? $item->target : '';
$atts['rel'] = ! empty( $item->xfn ) ? $item->xfn : '';
$atts['href'] = ! empty( $item->url ) ? $item->url : '';
$atts['class'] = ! empty( $class_names ) ? $class_names : '';
$atts = apply_filters( 'nav_menu_link_attributes', $atts, $item, $args, $depth );
$attributes = '';
foreach ( $atts as $attr => $value ) {
if ( ! empty( $value ) ) {
$value = ( 'href' === $attr ) ? esc_url( $value ) : esc_attr( $value );
$attributes .= ' ' . $attr . '="' . $value . '"';
}
}
$title = apply_filters( 'the_title', $item->title, $item->ID );
$title = apply_filters( 'nav_menu_item_title', $title, $item, $args, $depth );
$item_output = $args->before;
$item_output .= '<a'. $attributes .'>';
$item_output .= $args->link_before . $title . $args->link_after;
$item_output .= '</a>';
$item_output .= $args->after;
$output .= apply_filters( 'walker_nav_menu_start_el', $item_output, $item, $depth, $args );
}
public function end_el( &$output, $item, $depth = 0, $args = array() ) {
if ( isset( $args->item_spacing ) && 'discard' === $args->item_spacing ) {
$t = '';
$n = '';
} else {
$t = "\t";
$n = "\n";
}
$output .= "{$n}";
}
}
And set your wp_nav_menu args:
<?php
$menuParameters = array(
'theme_location' => 'primary',
'container' => false,
'echo' => false,
'items_wrap' => '%3$s',
'depth' => 0,
'walker' => new Custom_Walker_Nav_Menu()
);
// no need to strip tags since the custom walker already trimmed it
echo wp_nav_menu( $menuParameters );
?>
Don't forget to set css class in the Appearance -> Menus
