After editing a form I need to have it automatically update a field, last_updated, to the datetime like php now as you click to save. How do you do this?

    If you are using MySQL, your last_updated field would update automatically if you have defined it correctly.

    In the Editor world, you can also do it in the server-side scripts with Events - see the examples towards the end of this page,

    I looked at the page but javascript especially is not my skillset. With the aid of other searches I did the following. For testing I added a new field called timestamp as:

    Type: Timestamp
    Default: current_timestamp()

    I added the field in the Controller file:

    Field::inst('articles.timestamp') ->set(function ($data) { return date('Y-m-d H:i:s'); }),

    In the javascript file I added the field as:

    {
    label: "Current timestamp (field = timestamp)",
    name: "articles.timestamp",
    type: 'datetime',
    def: function () {
    return new Date(Date.now());
    }
    },

    It is not updating the timestamp which we want to include HH-MM-DD.

    You only need the timestamp field in your MySQL, and for queries. You don't want to edit it.

    MySQL should look like this:

    Name ; (your choice of name)
    
    Type: TIMESTAMP
    
    Default: CURRENT_TIMESTAMP
    
    Attributes: on update CURRENT_TIMESTAMP
    

    You should really be looking at MySQL sites. This is not a Datatables issue.

    My partner solved this by changing the Field in the controller file to:

    Field::inst('articles.modified')->set( Field::SET_EDIT ),

    The field type is date which is fine for what we need. Can you mark this as closed by the poster?
