Adding unique code to user profile

I need to add a unique code to a user profile when a new user is created VIA the admin.
- the person adding the user should not have to enter the code, it should be auto generated
- I need to be able to retrieve that code easily to generate some custom urls

I was wondering what the best method to start this would be, I can easily enough create a snippet that will generate the code, but as far as ’firing’ it and associating it with the user profile - am a bit stuck.....

Is there some documentation/examples for something similar I could read to get started?

What version of MODx? What field will the unique code be going in?

Revolution [the most recent build] - we are talking a new custom field, not re-purposing an existing one.

If you are talking about a single field you may be able to get away with using the extended fields tab.

If you are wanting to implement something more involved, you may want to take a look at my article in the docs:
http://rtfm.modx.com/display/revolution20/Extending+modUser. it should give you a starting point.

One way is to generate the code with time(), then add it to the user profile in a plugin connected to OnUserFormSave only when


That will keep it from happening when updating an existing user.

ok - lemme see if I got this right,

- create my extra DB table in mysql
- create and register the schema http://rtfm.modx.com/display/revolution20/Using+Custom+Database+Tables+in+your+3rd+Party+Components
- create a plugin that fires on the ’OnUserFormSave’ event http://rtfm.modx.com/display/revolution20/Plugins
Now here’s where it gets hazy, I should be able to now create a modx resource page containing a snippet that accesses the user object[??] and can retrieve that value/code for use?

not quite sure I understand the ’MODE_NEW’ part [I see what you are saying it does, just not where it comes from] of

Hi am I missing something here??

The user already has a unique id.

Just a thought!!

Hi Allan;

yes - the user does already have an ID, but I want something ’unguessable’ as they are to be used in public URLs i.e. http://_mysite.com/fileRequest.php?userid=1234-qwer&file=myfile

$mode  ==  modSystemEvent::MODE_NEW

I would use one of the unused fields in the user profile instead (fax?) It will be much easier and faster and won’t require a custom DB table.

The $mode variable is sent to the plugin automatically when the OnUserFormSave event is triggered and has only two possible values. All you have to do is check its value.

You can create the resource page in your plugin, and yes, a snippet can access the user object and send the user there.

ah so we are talking more along the lines of:



I’m not 100% sure about the ’unused field, theses users are companies - I have no idea what fields the end user is going to populate - but I do know they can’t be trusted not to ’fiddle’ with something, so I really do want that unique id to be well hidden & tamper proof.


Currently I do have the core stuff done, the database table, a plugin on the event that does insert a UUID on the form save [every time - will fix that today] - though the database call is the stand mysqlconnect provides user names and passwords, will need to find some docs and tutorials on how to interact with the database ’correctly’ today. [truth is I read too much documentation yesterday and got overloaded!]


Thanks for staying tuned, I really do appreciate the help.

Just tested, this works perfectly BTW
