单击/切换显示搜索字段时，在导航菜单中显示搜索图标-Wordpress

Question

I'm trying to add a search icon to my navbar on wordpress using wpresidence theme on Wordpress,

Once clicked, i would like the search bar to appear, i wouldn't mind if it makes use of the current advanced search feature.

Would be very grateful for your help

function add_last_nav_item($items, $args) {
  if ($args->menu == 'header_menu') {
        $homelink = get_search_form();
        $items = $items;
        $items .= '<li>'.$homelink.'</li>';
        return $items;
  }
  return $items;
}
add_filter( 'wp_nav_menu_items', 'add_last_nav_item', 10, 2 );

--- i've tried using bobsearch plugin and it didn't work and also entered this into my functions.php code but it didnt work

Your hook looks fine. But the condition maybe wrong. If you want to check theme location when register with them, try this:

if($args->theme_location == "header_menu")

$args objects is an object containing wp_nav_menu() arguments.

Here is searchform.php

<form role="search" method="get" class="search-form" action="<?php echo home_url(); ?>">
    <label>
        <input class="search-field" placeholder="Search" value="" name="s" type="search">
    </label>
    <input class="search-submit" value="Search" type="submit">
</form>
