I apologize for bothering you again but I just don't understand .. my code restricts the "ak-47 gold" weapon from being bought twice a round .. I wish I couldn't buy it if I have it in my hand, but if he throws it down, he can buy it from the shop again.

public zp_extra_item_selected(player, itemid)
{
	if ( itemid == g_itemid )
	{
	if(g_HasAk[player])
	{
	new name[32]
	get_user_name(player, name, 31)
	ColorChat(player, "^4[ZP]^3 %s^1, you already have the ^4Golden Kalashnikov^1 !", name);
	return ZP_PLUGIN_HANDLED;
	}
	if ( user_has_weapon(player, CSW_AK47) )
	{
	drop_prim(player)
	}

	give_item(player, "weapon_ak47")
	new name[32]
	get_user_name(player, name, 31)
	ColorChat(player, "^4[ZP]^3 %s^1, you bought ^4Golden Kalashnikov^1, Good Luck !", name)
	g_HasAk[player] = true;
	}
	return PLUGIN_CONTINUE;

Combine it: if ( g_HasAk[player] && user_has_weapon(player, CSW_AK47) )

Or
if ( user_has_weapon(player, CSW_AK47) )
{
drop_prim(player)
}
else g_HasAk[player] = false

I tried this variant and the other one, everything works as I would like, one problem ... now I don't lose ammo packs when I buy it ..

public zp_extra_item_selected(player, itemid)
{
	if ( itemid == g_itemid )
	{
	if(g_HasAk[player] && user_has_weapon(player, CSW_AK47))
	{
	new name[32]
	get_user_name(player, name, 31)
	ColorChat(player, "^4[ZP]^3 %s^1, you already have the ^4Golden Kalashnikov^1 !", name);
	return ZP_PLUGIN_HANDLED;
	}
	if ( user_has_weapon(player, CSW_AK47) )
	{
	drop_prim(player)
	}

	give_item(player, "weapon_ak47")
	new name[32]
	get_user_name(player, name, 31)
	ColorChat(player, "^4[ZP]^3 %s^1, you bought ^4Golden Kalashnikov^1, Good Luck !", name)
	g_HasAk[player] = true;
	}
	return PLUGIN_CONTINUE;

use another variable + new round event .
also use first variant from original post or else if you have ak in your hands when buying you won't lose ammo(can be exploited as a bug)

PHP Code:

//add this at the top
new g_bought
//add this to plugin_init()
register_event("HLTV", "event_new_round", "a", "1=0", "2=0")
//event new round
public event_new_round()
{
    // i dont know if this is supposed to loop through all players but i'm sure some1 will correct me
    g_bought = 0
}
//extra item selected
public zp_extra_item_selected(player, itemid)
{
    if ( itemid == g_itemid && g_bought = 0)
    {
    if(g_HasAk[player])
    {
    new name[32]
    get_user_name(player, name, 31)
    ColorChat(player, "^4[ZP]^3 %s^1, you already have the ^4Golden Kalashnikov^1 !", name);

line problem

    if(itemid == g_itemid && g_bought = 0);

I thought of a simpler solution ... but honestly I'm not very good at it, I thought that in the round where he buys the golden ak-47 he can't throw it down until the next round when he will give it a and normal.

that can work but it's not as simple as you make it out to be , not dropping it is a different code from zp_extra_item_selected() and will cause error by contradicting with the stock drop_prim() when buying so the new round solution is simpler now for my code :
if(itemid == g_itemid && g_bought = 0); >>>>>> if(itemid == g_itemid && g_bought == 0);

my mistake .

Edit : if you want a chat message to be added to that like "this item can onlt be bought once per round" , just ask

don't forget to remove the ";" after "if ( itemid == g_itemid && g_bought == 0)" the error comes from there
