Just renaming the "back" option won't work as MENU_BACK and MENU_NEXT don't trigger the menu handler.
Not sure what you mean by "I don't trust that code", if you are not aware, newmenus is just a oldmenu but made with the intent to make the developer's life easier whenever one needs a menu with dynamic items/pagination.
Newmenus does store the items in a vector, as I did with arrays
Code:
menuitem *Menu::AddItem(const char *name, const char *cmd, int access)
{
menuitem *pItem = new menuitem;
pItem->name = name;
pItem->cmd = cmd;
pItem->access = access;
pItem->id = m_Items.length();
pItem->handler = -1;
pItem->isBlank = false;
pItem->pfn = NULL;
m_Items.append(pItem);
return pItem;
}
If you check the source code of newmenus, you will clearly see that it does pretty much the same thing under the hood.

So again, I don't get your point, maybe you should provide a working solution, otherwise whatever you say is irrelevant.
-----------------
menu_additem doesn't actually add an item to the menu, it just stores it to a list of items to be used later when you call menu_display.
The problem with the oldmenu approach is that it assumes all items to be available in the menu when calculating the pagination, no matter the location, for that reason, skipping an item from being added won't behave as newmenus.
To get that done, you first have to define which items should be skipped. A solution would be to loop through all items and store the indexes of the ones to be added in a temporary array and use that array to create the menu instead of the g_menuItems one.
Working solution:
Code:
#include <amxmodx>
#include <amxmisc>
new Array:g_menuItems
enum _:ArrayTest
{
Location,
Item[ 32 ]
}
new g_playerMenuPage[33]
new g_menuloction[33]
new g_playerMenuItemData[33][10]
new eData[ ArrayTest ]
public plugin_init()
{
g_menuItems = ArrayCreate(ArrayTest)
for (new i = 1; i <= 5; i++)
{
eData[ Location ] = 1;
copy( eData[ Item ], charsmax( eData[ Item ] ), fmt( "Item %d", i ) )
ArrayPushArray(g_menuItems, eData )
}
for (new i = 1; i <= 5; i++)
{
eData[ Location ] = 2;
copy( eData[ Item ], charsmax( eData[ Item ] ), fmt( "ItemPlus %d", i ) )
ArrayPushArray(g_menuItems, eData )
}
register_clcmd("say /menu", "@TestMenu")
register_menu("Cool Menu", -1, "MenuHandler")
}
@TestMenu( id )
{
new iMenu = menu_create( "\yTest Menu:", "@TestHandler" );
menu_additem( iMenu, "Location One", "1" );
menu_additem( iMenu, "Location Two", "2" );
menu_display(id, iMenu)
return PLUGIN_HANDLED;
}
@TestHandler( id, iMenu, iItem )
{
if(iItem != MENU_EXIT)
{
new szData[ 10 ], iUnused;
menu_item_getinfo( iMenu, iItem, iUnused, szData, charsmax( szData ), .callback = iUnused )
new iItemID = str_to_num( szData );
ShowMenu(id, iItemID )
}
menu_destroy(iMenu);
return PLUGIN_HANDLED;
}
public ShowMenu(index, iLocation )
{
new Array:itemsToAdd = ArrayCreate()
for (new i = 0, data[ArrayTest], count = ArraySize(g_menuItems); i < count; i++)
{
// Add any item skipping logic here
ArrayGetArray(g_menuItems, i, data)
if (data[Location] && data[Location] != iLocation)
{
continue
}
ArrayPushCell(itemsToAdd, i)
