🎒 qb-inventory

Store your precious!

Introduction

• Handles all the player's storage such as personal, vehicle, stash, drops
• qb-shops integration for displaying all items available to buy
• Built-in support for usable vending machines

Item Info

Tip

You can use SetItemData to achieve this

Items support additional information that can be added to them via an info attribute. This information will display on the item when the player hovers over it in a key,value pair format. You can also add a special display keyword and make it false to hide any data inside the info table from being shown!

RegisterServerEvent('addItemWithInfo', function(source, args)
    local itemName = args[1]
    if not itemName then return end
    local info = {
        uniqueData1 = 'uniqueData1',
        uniqueData2 = 'uniqueData2',
        uniqueData3 = 'uniqueData3',
        uniqueData4 = 'uniqueData4',
    }
    exports['qb-inventory']:AddItem(source, itemName, 1, info, 'qb-inventory:testAdd')
end)

RegisterServerEvent('editItemWithInfo', function(source)
    local Player = QBCore.Functions.GetPlayer(source)
    if not Player then return end
    local items = Player.PlayerData.items
    local itemInfo = items[1]
    print(json.encode(itemInfo, { indent = true }))
    itemInfo.info = {
        newInfo = 'New Info'
    }
    print(json.encode(itemInfo, { indent = true }))
    items[1] = itemInfo
    Player.Functions.SetPlayerData('items', items)
end)

Server Functions

LoadInventory

This function retrieves the player's inventory from the database using their citizenid, decodes it from JSON, and builds a structured table of items using data from QBCore.Shared.Items. If an item is found that no longer exists in the shared items table, it is skipped and logged to the console. The returned inventory contains detailed information like item label, weight, image, and usage properties

• source: number
• citizenid: string
• returns: table

RegisterServerEvent('getInv', function(source)
    local Player = QBCore.Functions.GetPlayer(source)
    local citizenId = Player.PlayerData.citizenid
    local items = exports['qb-inventory']:LoadInventory(source, citizenid)
    print(json.encode(items, { indent = true }))
end)

SaveInventory

Saves the player's current inventory to the database by serializing item data into JSON format. Supports both online and offline player data

• source: number
• offline: boolean

RegisterServerEvent('saveInv', function(source)
    exports['qb-inventory']:SaveInventory(source)
end)

ClearInventory

Clears a player's inventory, optionally preserving specific items by name. Updates player data, logs the action, and removes the currently equipped weapon if applicable

• source: number
• filterItems: string | table

RegisterServerEvent('clearInventoryExcludeItem', function(source, args)
    local filterItem = args[1]
    if not filterItem then return end
    exports['qb-inventory']:ClearInventory(source, filterItem)
    print('Inventory cleared for player '..source..', excluding item: '..filterItem)
end)

RegisterServerEvent('clearInventoryExcludeItems', function(source)
    local filterItems = {'item1', 'item2'}
    exports['qb-inventory']:ClearInventory(source, filterItems)
    print('Inventory cleared for player '..source..', excluding items: '..table.concat(filterItems, ', '))
end)

ClearStash

Empties all items from the specified stash inventory and updates the database to reflect the cleared state

• identifier: string

RegisterServerEvent('clearstash', function(source, args, raw)
    local stashId = args[1]
    exports['qb-inventory']:ClearStash(stashId)
    print('Stash '" .. stashId .. "' has been cleared.")
end)

CloseInventory

Closes the specified inventory and marks the player as no longer busy, then notifies the client to close the inventory UI

• source: number
• identifier: string

RegisterServerEvent('closeInventory', function(source)
    exports['qb-inventory']:CloseInventory(source)
    print('Inventory closed for player '..source)
end)

RegisterServerEvent('closeInventoryByName', function(source, identifier)
    exports['qb-inventory']:CloseInventory(source, identifier)
    print('Inventory closed for player '..source..' and inventory '..identifier..' set to closed')
end)

OpenInventory

Opens a specified inventory or the player's own if no identifier is given. Prevents access if the inventory is already in use, initializes it if needed, and sends formatted inventory data to the client for display

• source: number
• identifier: string | optional
• data: table | optional

RegisterServerEvent('openinv', function(source)
    exports['qb-inventory']:OpenInventory(source)
end)

RegisterServerEvent('openinvbyname', function(source, args)
    local inventoryName = args[1]
    exports['qb-inventory']:OpenInventory(source, inventoryName)
end)

RegisterServerEvent('openinvbynamewithdata', function(source, args)
    local inventoryName = args[1]
    local data = { label = 'Custom Stash', maxweight = 400000, slots = 500 }
    exports['qb-inventory']:OpenInventory(source, inventoryName, data)
end)

OpenInventoryById

Opens another player's inventory for viewing or interaction, formatting their data for display and marking their state as busy to prevent conflicts

• source: number
• playerId: number

RegisterServerEvent('openplayerinv', function(source, args)
    local playerId = tonumber(args[1])
    exports['qb-inventory']:OpenInventoryById(source, playerId)
end)

Tip

OpenInventoryById will close the target players inventory (if open) and lock it via state. It will then unlock when the opening player closes it

CreateInventory

Creates and registers a new inventory using the provided identifier and initialization data if it doesn't already exist

• identifier: string
• data: table

RegisterServerEvent('createinv', function(source, args)
    local id = args[1]
    if not id then
        print('Usage: /createinv [identifier]")
        return
    end
    exports['qb-inventory']:CreateInventory(id, {
        label = "Custom Inventory',
        maxweight = 100000,
        slots = 30
    })
    print('Inventory '" .. id .. "' created.")
end)

RemoveInventory

Deletes the inventory associated with the specified identifier from the in-memory registry

• identifier: string

RegisterServerEvent('removeinv', function(source, args)
    local id = args[1]
    exports['qb-inventory']:RemoveInventory(id)
    print('Inventory '" .. id .. "' removed.")

local items = {
    { name = 'sandwich', amount = 10, price = 5 }
}

RegisterServerEvent('createShop', function(source)
    local playerPed = GetPlayerPed(source)
    local playerCoords = GetEntityCoords(playerPed)
    exports['qb-inventory']:CreateShop({
        name = 'testShop',
        label = 'Test Shop',
        coords = playerCoords, -- optional
        slots = #items,
        items = items
    })
end)

Tip

Coords being passed to createShop will be checked against the player's current coords when OpenShopis called if coords were provided during createShop

OpenShop

    if canAdd then
        print('Can add '..amount..' of item '..itemName)
    else
        print('Cannot add '..amount..' of item '..itemName..'. Reason: '..reason)
    end
end)

• returns: boolean

RegisterServerEvent('addItem', function(source, args)

            type = 'item',
            info = {},
            slot = 1
        },
        {
            name = 'water_bottle',
            amount = 10,

            info = {},
            slot = 2
        }
    }
    exports['qb-inventory']:SetInventory(source, items)
end)

SetItemData

Sets a specific key-value pair in a player's item data and updates the player's inventory with the modified item. If a slot number is provided, it directly targets the item in that slot. Otherwise, it uses GetItemByName to find the first matching item by name

• source: number
• itemName: string
• key: string
• val: string | table
• slot: number (optional)
• returns: boolean

RegisterServerEvent('setItemData', function(source, args)

    local val = args[3]
    if not itemName or not key or not val then return end
    local success = exports['qb-inventory']:SetItemData(source, itemName, key, val)
    if success then
        print('Set data for item '..itemName..': '..key..' = '..val)
    else

    local val = { worth = 1000 }
    if not itemName or not key or not val then return end
    local success = exports['qb-inventory']:SetItemData(source, itemName, key, val)
    if success then
        print('Set data for item '..itemName..': '..key..' = '..json.encode(val, { indent = true }))
    else
        print('Failed to set data for item '..itemName)
    end
end)
