How is it the wrong section when he's asking how to do it?

--------------

Create a global variable with 2 dimensions - the player index and item index.
Increase [id][item] by 1 when buying the item.
Check if [id][item] reached your desired limit, stop the code if it did.
When the player dies, loop through all player indexes and use arrayset() to reset the limit for each item.

Umm, i thought we wanted us to edit the plugin? + he didn't provide any sma either

That's just one way of doing it
PHP Code:
#include <amxmodx>

new ItemUsed = 5 // its purpose is Global
new ItemId[33] // its purpose is to hold the items

public plugin_init()    
    register_clcmd( "say /menu","AwesomeMenu" );

public AwesomeMenu( id )
{
    new menu = menu_create( "Look at this awesome Menu!:", "menu_handler" );

    menu_additem( menu, "I'm Selection #1", "", 0 );
    menu_additem( menu, "I'm Selection #2", "", 0 );

    menu_setprop( menu, MPROP_EXIT, MEXIT_ALL );

    menu_display( id, menu, 0 );

}

public menu_handler( id, menu, item )
{
    if(ItemId[item] == ItemUsed) //if the selected item equals 5 (gItemUsed) we return
    {
        client_print(id,print_chat,"Limit reached")
        return
    }
    
    ItemId[item]++ //we increase the picked item's number by 1

    switch(item)
    {
        case 0:client_print( id, print_chat, "Item 1 can be used: %i/%i times", ItemId[item],ItemUsed)
        case 1:client_print( id, print_chat, "Item 2 can be used: %i/%i times", ItemId[item],ItemUsed)
    }
}

That's a global limit for all items, not per player.

Normally you would do something like this instead.

PHP Code:
enum _:eShopItems {

        ITEM_NAME[32],
        ITEM_COST,
        ITEM_MAX_USES,
        etc...
};

// Here are your item definitions
new const g_ShopItems[MAX_ITEMS][eShopItems] {

        { "Item 1", 16000, 5, etc.}, 
        { "Second item", 8000, 3, etc.}, 
        etc.
} 
Then accordingly acces each element using the enumeration for better coordination. What you did there was define a max usage for every item.

Re: Max Usage Of A Item In Shop
 
Yes, my bad.
Ideally then it should be somewhat like this
PHP Code:
#include <amxmodx>

new ItemUsed[33][33]

enum _:Items
{
    Name[64],
    Limit[33]
}

new const szItemInfo[2][Items] =
{
    {"Item 1", 5},
    {"Item 2", 3}
}

public plugin_init()
    register_clcmd("say /menu","openmenu")

public openmenu(id)
{
    new menu = menu_create("Testing","menu_handle")
    for(new i; i<2; i++)
    {
        static szMenuTitle[64], szInfo[3]
        
        formatex(szMenuTitle, charsmax(szMenuTitle), "%s",szItemInfo[i][Name])
        num_to_str(i, szInfo, charsmax(szInfo))
        menu_additem(menu, szMenuTitle, szInfo)
    }
    
    menu_setprop(menu, MPROP_EXIT, MEXIT_ALL)
    menu_display(id, menu, 0);
    return PLUGIN_HANDLED
}

public menu_handle(id,menu,item){
    if(item == MENU_EXIT || !is_user_alive(id))
    {
        menu_cancel(id)
        return
    }
    if(ItemUsed[id][item]++ >=  szItemInfo[item][Limit])
    {
        client_print(id,print_chat,"Item limit reached")
        return
    }
    switch(item){
        case 0:client_print(id, print_chat, "Option 1");
        case 1:client_print(id, print_chat, "Option 2");
    }
}

Re: Max Usage Of A Item In Shop
 
PHP Code:
enum _:Items
{
    Name[64],
    Limit[33]
} 
Why is Limit an array? It only takes one number. Name is an array of characters or a string with a maximum of 64 characters available in this case.


If you're on AMXX 1.9 or greater, consider ditching the formatex function and using fmt(). You'd get this:
PHP Code:
    for(new i; i<2; i++)
    {
        static szInfo[3]
        
        num_to_str(i, szInfo, charsmax(szInfo))
        menu_additem(menu, fmt("%s", szItemInfo[i][Name]), szInfo)
    } 
Be careful though, if you were to use fmt inside another fmt, you'd get errors, but this is a much better approach in your case.


Also, there is no need to increment ItemUsed in there if the condition results in false, just put it under the switch statement.
