Nawr rydw i eisiau gallu mewnosod arae ynddo, naill ai cyn neu ar ôl unrhyw un o'r allweddi yn yr arae uchod. Gall yr arae rydw i am ei mewnosod edrych fel hyn:

$new_menu_buttons['testing'] = array(
    'title' => $txt['testing'],
    'href' => $scripturl . '?action=testing',
    'show' => true,
    'target' => '_self',
    'active_button' => false,
);

Roedd rhywun yn argymell swyddogaethau i drin hyn a dulliau i'w defnyddio, ond nid wyf yn siŵr sut i wneud hyn, maent eisiau gwrthbwyso ar gyfer y swyddogaethau hyn hefyd. Dyma'r strwythur swyddogaeth yr argymhellodd rhywun y dylwn ei ddefnyddio ar gyfer hyn, na galw'r swyddogaethau hyn yn ôl yr angen:

function array_insert_before($array, $key, $new_array)
{
    // Splice array in two at key, keeping key on the right side
    // Append new value on the left tail
    // Glue both arrays into a new array
    // Return new array
}
function array_insert_after($array, $key, $new_array)
{
    // Symmetric with right & left switched
}

Felly , Rwyf am allu galw'r swyddogaethau fel hynny:

Os oes angen iddo fynd ar ôl yr allwedd, 'cartref' a bennir:

$menu_buttons = array_insert_after($buttons, 'home', $new_menu_buttons);

Os oes angen iddo fynd cyn yr allwedd, 'cartref' a bennir :

$menu_buttons = array_insert_before($buttons, 'home', $new_menu_buttons);

Yn y bôn, mae gwir angen help arnaf gyda'r swyddogaethau hyn, byddai unrhyw help yn wych.

A ddylwn i fod yn defnyddio array_splice neu array_slice ? A fyddai rhywun yn barod i fy nghychwyn i'r cyfeiriad cywir yma gyda rhywfaint o god gwirioneddol os gwelwch yn dda?

Diolch bois :)
