First tutorial so go easy on me... i have been experimenting for the past couple of hours and made my own basic inventory system that saves the items... and are in dialogs! So here goesssss 
You have to have YSI include and zcmd. You can download them here:

Right, I'm making this inventory system assuming you already have an admin/login/register system setup and so you can just add this to your system, for saving.
FIRST THINGS FIRST:
define your dialog ids, for the sake of this tutorial, this is what i've gone with!
first of all of course you have to add what you wish to save, I've done drugs and a newspaper for the sake of the tutorial xD We have added pDrugs, pNewspaper, and pInventory to our enum which will allow us to make these things save! We have added inventory so that we can check if the inventory space is full, or how much is left in the inventory!
Right, now you've done that, we need to add the following to the disconnect callback! To ensure that everything works properly, saves and loads, we must add the newspaper, inventory and drugs to the callbacks that your admin system uses! This will save the variable into the file for the user of which is disconnecting... and say you have 10 drugs, it will save those 10 drugs into the ini folder after Drugs... for example : Drugs = 10... and the same goes for newspaper and inventory... but the inventory is calculated by adding the 2 variables together...
we'll go into further detail later down the tutorial!
now we have to add the following code to the onplayerdeath callback. What this does is it sets the variables in the save file back to 0, meaning you lose everything once you die! Pretty self explanatory really!
Now, lets make a command that gives us the drugs, adding it to the save file! This is where you can really mess around the the variables and create a nice system. For the sake of the tutorial, I've kept it very simple for you guys... So, the following script will create a command, which will check the inventory space, add to the inventory space and make sure that you have sufficient inventory space for the item you're trying to add, in this case, it's drugs (no specific drug for the sake of the tutorial...
now we've made that command, we must also make a command for the newspaper... which works exactly the same, just changing the variable names!
A very simple command checking the inventory! All we have done here, is show the inventory dialog (the command is the writ in ondialogresponse)
right, we're almost there guys!!
Just one more thing! We have to add the variables to the load user function...
thats the tutorial guys! if you have any tips on how i can improve this tutorial or code... then sure do say so!
I'd also appreciate it if you wouldn't turn around and just tell me it's shit, let me know why it's not so good! remember it's my first tutorial and from all i can tell, through me testing it, it works fine

FIRST THINGS FIRST:
define your dialog ids, for the sake of this tutorial, this is what i've gone with!

I'd also appreciate it if you wouldn't turn around and just tell me it's shit, let me know why it's not so good! remember it's my first tutorial and from all i can tell, through me testing it, it works fine
