Hi to all,
I need to have an attribute of a class to be unique in it's value in the administration site.
My site has many products each with a unique code, at the admin site I would like to let other introduce instances of the product class but when inserting the code value they shoúld get an error if the code has been already entered (when they press the acept button send for publication)
The only idea I have is to have the attribute to be unique at the database and get the error when trying to insert the information but this does not seems the right thing to do... (messing with the database)
Uniqueness at the code attr. is needed whe inserting data in de admin site, this is a must.
thanks fot new ideas!

Thanks
I am using ez 310, and the extension is meant for 4.X
is there some way I could use it for 3.10
thanks again!

Yup, upgrade as soon as possible ;)
And if that's impossible, I don't remember exactly, but I don't think there is any advanced object-oriented PHP code inside, so it should be quite moveable backwards with little effort. I don't plan anything like that, though ;)

Hi again,
Sorry to bother, the only thing I cannot find how to "traslate" to php4 are codes in the following form:
return eZInputValidator::STATE_INVALID; return self::validateUniqueStringHTTPInput( $data, $contentObjectAttribute );eZDataType::register( eZUniqueStringType::DATA_TYPE_STRING, "eZUniqueStringType" );
Can you spare 3 minutes please and transfrom the lines that has "::" to whatever php4 needs.

return eZInputValidator::STATE_INVALID; eZDataType::register( eZUniqueStringType::DATA_TYPE_STRING, "eZUniqueStringType" );
These two you should be able to look up in any built-in datatype of 3.x, and those are located in /kernel/classes/datatypes/...
return self::validateUniqueStringHTTPInput( $data, $contentObjectAttribute );
This should work in both versions, you may try to substitute self:: with proper class name.
Sorry, but I've never written PHP for 3.x...
