How to insert search form into header_posline next to phone number?

I just did in the last post, but here it is again.

<?php

/*
* Add your own functions here. You can also copy some of the theme functions into this file.
* WordPress will use those functions instead of the original functions then.
*/

add_action( 'ava_main_header', 'enfold_customization_header_widget_area' );
function enfold_customization_header_widget_area() {
  dynamic_sidebar( 'header' );
}

add_filter("kriesi_backlink","new_link");
function new_link(){
$kriesi_at_backlink = "";
return $kriesi_at_backlink;
}

add_filter( 'avf_execute_avia_meta_header', '__return_true', 10, 1);
add_filter( 'avia_meta_header', 'avia_append_search_nav_mod');
function avia_append_search_nav_mod(){
          global $avia_config;
          ob_start();
          get_search_form();
          $form = htmlspecialchars(ob_get_clean());

          $items .= '<li id="menu-item-search" class="noMobile menu-item menu-item-search-dropdown menu-item-avia-special">
                        <a href="?s=" data-avia-search-tooltip="'.$form.'" '.av_icon_string('search').'>
                        <span class="avia_hidden_link_text">'.__('Search','avia_framework').'</span>
                        </li>&nbsp;&nbsp;';
        echo $items;
}

function custom_shift(){
?>
<script>
(function($){
//      $('#header_meta #menu-item-search').prependTo('#avia2-menu');
        $('#header_meta #menu-item-search').prependTo('#header_meta .sub_menu');
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'custom_shift');

/* Create shortcode for parent page. */
function list_parent_page() {
  global $post;
  $parent_id = $post->post_parent;
  $parent = $post->post_parent;
  $parent_title = get_the_title($parent);
  $link = get_permalink($parent_id);
  $parent_title = "<a href='$link' title='$parent_title'>$parent_title</a>";
 if($parent) {
        return $parent_title;
  }
}
function list_current_page() {
  get_the_title();
}
add_shortcode('parentpage','list_parent_page');
add_filter( 'widget_title', 'do_shortcode' );

// fix for PHP shortcode
function do_php_shortcode_fix($content) {
    global $shortcode_tags;
    // save current shortcodes
    $old_shortcode_tags = $shortcode_tags;
    // remove all shortcodes, then re-add just our php and echo shortcodes
    remove_all_shortcodes();
    add_shortcode('php', $old_shortcode_tags['php']);
    add_shortcode('echo', $old_shortcode_tags['echo']);
    $content = do_shortcode($content);
    // and now put back the original shortcodes
    $shortcode_tags = $old_shortcode_tags;
    return $content;
}
function fix_php_shortcode_init() {
    global $shortcode_tags;
    if (isset($shortcode_tags['php'])) {
        // Move do_shortcode back to default of priority 11
        if(remove_filter('the_content','do_shortcode', 9))
            add_filter('the_content','do_shortcode', 11);

        // filter the content to deal with just the php and echo shortcodes
        // early on as priority 8 (before any WP formatting)
        add_filter('the_content', 'do_php_shortcode_fix', 8);
    }
}

// add fix for PHP shortcode, with priority 12 so it
// comes after the PHP shortcode has been initialised
add_action('init','fix_php_shortcode_init', 12);

Are you are correct, my mistake there when retyping it.
Now that I’ve inserted the both search items vanished.

add_filter( 'avf_execute_avia_meta_header', '__return_true', 10, 1);
add_filter( 'avia_meta_header', 'avia_append_search_nav_mod');
function avia_append_search_nav_mod(){
          global $avia_config;
          ob_start();
          get_search_form();
          $form = htmlspecialchars(ob_get_clean());

          $items .= '<li id="menu-item-search" class="noMobile menu-item menu-item-search-dropdown menu-item-avia-special">
                        <a href="?s=" data-avia-search-tooltip="'.$form.'" '.av_icon_string('search').'>
                        <span class="avia_hidden_link_text">'.__('Search','avia_framework').'</span>
                        </a>
                        </li>';
        echo $items;
}

function custom_shift(){
?>
<script>
(function($){
//      $('#header_meta #menu-item-search').prependTo('#avia2-menu');
        $('#header_meta #menu-item-search').prependTo('#header_meta .sub_menu');
})(jQuery);
</script>
<?php
}
add_action('wp_footer', 'custom_shift');

That’s more than fine, thank you for your assistance, almost seems like it is worth me to break the code and remove that closing so it appears again, thank you!

Hopefully the devs check this ticket soon too.

Apologies for the lack of updates here, the end resolution for me was to hire a web developer with more experience than me.
They went through and recoded / overwrote a bunch of css to fix the issue. Combined with modifications in the child theme helper-main-menu.php file

The main changes were done in Appearance -> Customize CSS to override the themes css

.header-searchform {
	display: inline-block;
	padding-right: 1em;
	text-align:left;
}
.header-searchform .ajax_search_response {
background-color:#fff;	
	position:absolute !important;
}
.menu-item-search {
	display:none;
}

#header_meta {
	text-align:right;
}
.custom-header-buttons {
	width:100%;
	display:flex;
	justify-content:space-between;
}
	#header_posline {
		width:100%;
		margin-right:0px;
		display:block !important;
		margin-top:10px;
		z-index:9999;
}
@media screen and (min-width:992px){
	#header_posline {
		width:calc(100% - 230px);	
	max-width:737px;
		margin: 0 auto;
		right: 45px;
		position:absolute;
		top:-12px;
	}
	
	.header-button {
		height:55px;
	}
	
	
}

.header-button a {
	display:block;
	height:45px;
}

Hopefully this may help someone, I kept forgetting to come back here and I hate finding tickets that are open without a resolution
