I have made a custom field for user
field_custom_xyz from the admin GUI.
Now after i saved it i got two tables into the database : one for data and one for revisions.
I already have a huge database into which a lot of users are already there.
I have two questions :
- How can i make sure that i can assign default value to each user at the time of creation of this field?
- Let's say if i have to assign a default value of
0(or null in case i don't follow step 1).
how can i change that value at the time of new registration using hook_user_presave ?
I want to override the default value of this field using
user_presave hook in some custom module lets say 'abc' module
so far i have tried :
$account->field_custom_abc['und']['value'] = 0;
but that doesn't work, any suggestions. thanks in advance.
