Hello AM, I populate a menu with data from an .ini file, however, I would like to populate the menu with data from Back to Front (newer to older), but I found nothing about...

Thanks.

Not sure if that would work, but you can try recursion

It would work and is the simplest way to handle this, IMO.

Don't listen to him, just do as JocAnis suggested, this is not that complicated.

Simplesmente, você le o arquivo normalmente de cima pra baixo e quando você for registrar o menu, comece do ultimo, pegando os valores decrescentes. Tipo, normalmente se utiliza o loop usando ++, é só você trocar pro --, tipo assim:

PHP Code:
// "i" will start with the MAX_VALUE readed, the loop will continue 'til the "i" be equal to or less than 0.
for(new ArraySize(g_arIniFileData);0;i--) 
E provavelmente, quando você for registrar o menu, mesmo usando o loop ao contrário, quando você for selecionar a opção ele ainda vai começar do 0 ao valor maximo que você registrar, então é necessário você passar a ID do item também pro handler, assim você pode saber que opção EXATA o jogador vai selecionar.

Basically:

Simply, you read the file normally, and when you'd create the menu, use the loop backwards, instead of increasing, you decrese the value, something like I showed. And probably, when you do register the menu, even using the reverse loop, after you select the option it'll still start from the 0 to the max value you registered without the menu_get_iteminfo, so you'll need to pass the ID of the item to the menu handler, with this, you'll be able to know which EXACT option the player would select.

for(new i = ArraySize(g_arIniFileData);i > 0;i--)

should be

for(new i = ArraySize(g_arIniFileData) - 1 ; i >= 0 ;i--)

or you will get an index out of bounds on the first pass using g_arIniFileData[ i ] and you also want to allow 0 to be accessed so >= 0 should be used.

It worked, thanks to everyone who helped me, my mistake was at the end of the loop, because instead of decreasing I was adding value (inattention).
