Xataface Forums

Hi,

I want Xataface to execute some commands whenever value of a field is changed.

How can I handle this?

I know that there are two triggers available to be implemented in a table's delegate class. (AfterUpdate and AfterSave) Problem is I don't know how to understand that value of a field is changed during execution of one of these triggers since I can only see the last value either updated or not from the database?

In the beforeSave, beforeUpdate, and beforeInsert triggers you can check for changed values.

e.g.

Code: Select all

beforeSave($record){
    if ( $record->valueChanged('myfield') ){
        // Do something .. the value for the field 'myfield' has been changed.
    }
}


Thanks
