Breadcrumbs when a parent menu item is a custom link

Thank you, Ismael, for your reply. I appreciate your help.

The problem with your suggested parent solution is that there are no actual pages for most of my parent menus, as they are custom links pointing to their first child. For example, the About parent points to its first child, Our Office Highlights. So I can’t set the Parent Page of any of the child pages (e.g. Our Office Highlights, Meet Us, etc.), since the About page does not exist (even typing into that text box, “About”, doesn’t work, since it wants you to choose from the dropdown of existing pages).

Thanks,
Gary

Thanks, Ismael.

But that doesn’t solve the problem of “About” not being in the breadcrumbs. In fact, I already change the color of the About parent menu item when any of it’s children are active.

What we’re really looking for is overriding some PHP or even JavaScript functions in some fancy way to insert the parent menu items that are custom links instead of pages into the breadcrumbs. I’m a computer programmer/analyst myself and could in theory do it. But frankly it would just be too much work for me to figure it all out. I was just hoping you guys have already run across this issue and have a solution in your pocket.

If none of you do, it might just be best for me to just hard-code the breadcrumbs in HTML on each page.

Thanks,
Gary

Thank you very much Ishmael. Your code does not quite work, as it returns the breadcrumb trail as “Home > Meet Us > About” instead of “Home > About > Meet Us”, but it gave me a starting point to produce the right code. FYI: you’re also just missing a closing “)” on the ‘if’ statement. Here is my solution, which works (I’m a programmer):

function avia_adjust_breadcrumb($trail) {
    
    /* We're assuming $trail is an array with sequential keys starting from [0], each element containing the breadcrumb for a menu item from an hierarchical menu structure, with the last element having the key 'trail_end' and containing the menu item breadcrumb of the current page.
      This function's purpose is to manage the situation where a parent menu item is a custom link instead of a page. Because Enfold's breadcrumbs don't include menu items that are custom links instead of pages, this function checks if the current page is a child of such a parent, and if it is, inserts that custom link type of parent breadcrumb into the $trail before the current page breadcrumb. Both the check if current page is a child of such a parent as well as the link of the parent are hardcoded in this function.
      For example, if the actual current breadcrumbs should be "Home > About > Meet Us", but About is a link instead of a page, then $trail comes into this function as {
            [0] => <the link to the Home page>,
            ['trail_end'] => "Meet Us" },
          or in other words, "Home > Meet Us". So this function changes $trail to be "Home > About > Meet Us"--i.e. returns it as: {
            [0] => <the link to the Home page>, 
            [1] => <the link to the page About points to (which could e.g. be its first child menu item, Our Office Highlights)>,
            ['trail_end'] => "Meet Us" }. */

    $parentIsCustomLink = false;
    $parentBreadcrumb = "";
    
    if (is_page([36, 38, 40, 42, 44])) {
        $parentIsCustomLink = true;
        $parentBreadcrumb = '<a href="https://www.mydomain.com/our-office-highlights/" title="About" rel="home" class="trail-begin">About</a>';
    }
    /* >>> ADDITIONAL PAGE CHECKS INSERTED HERE <<< */
    if ($parentIsCustomLink) {
        $elementCount = count($trail);
        $error = false; // If something is not as expected in $trail, then $error will be set to true.
        $customParentKey = 0; //Just initialize it to a numerical value in case there is no 'trail_end' key in $trail.
        $trailEndKeyExists = false;
        for ($i = 1; $i <= $elementCount; $i++) {
            $currentKey = key($trail);
            if ((string)$currentKey == 'trail_end') {
                $trailEndKeyExists = true;
                $customParentKey = $i-1;
                if ($i !== $elementCount) {
                    $error = true;
                    break;
                }
            }
            else
                $newTrail[$currentKey] = $trail[$currentKey];
            next($trail);
        }
        if ($error) //Then just return $trail unchanged and exit
            return $trail;
        $newTrail[$customParentKey] = $parentBreadcrumb;
        $newTrail['trail_end'] = $trail['trail_end'];
        unset($trail);
        return $newTrail;
    }
    else
        return $trail;
}
add_filter('avia_breadcrumbs_trail', 'avia_adjust_breadcrumb', 50, 1);

Thanks again,
