new queries

[ctrapp...@gmail.com]

Hi,

I created a pog object For a users table. I want to add a query to it
that checks if a user exists (via his username not userid). I will
add this function and query myself. However, what if requirements
change and I have to add a field? Does this mean I need to re-add my
function or is there some better way?

You basically have 2 options.

you can extend your users object and put the query there. Thus, when
you regenerate the base object, it won't affect your custom function.

moreover, as from 3.0 you'll be able to write a plugin to allow this
sort of customization, but on a project level... i.e. you can create a
plugin which will check if an object exist based on an arbitrary field
instead of object id.

option 1 seems to be the best solution for you. #2 is to make custom
function even more generic and re-usable.

regards,
joel

Create a separate function in a file and store it in your includes folder so
you don't need to add this in your object every time you change it. I
suspect that the pog plug-ins will be in similar manner but they will extend
and object and will be available thought an object method.

// example code. Not tested
function check_user_exist($username) {
$user= new user();
$user = $user->GetList(array(array("username", "=", $username));
If count($user>0) {
return true;
}
else
return false;
}
}
