Hello again,
I'm in the process of migrating our datatypes from PHP4 to PHP5 and had a look
on the code in eZP to register datatypes.
Currently you register the NAME of the datatype and eZP searches in a very
time consuming way for the file, that contains the CLASS for the datatype.
Because there is no possibilty[1] in PHP to get the name of a class in a file
you included, you have to put a line like the following in the file
containing the datatype-class:
eZDataType::register( EZ_DATATYPESTRING_BIRTHDAY, "ezbirthdaytype" );
That's not PHP5-ish since a file defining a class should not contain any
global code.
A very simple workaround and upgrade path could be:
1. Add the AvailableDataTypeClasses setting to content.ini, which defines the
CLASS of a datatype.
2. Write an ezpDataType[2] interface with the method
public static getIdentifier();
to return the NAME of a datatype.
3. Adapt eZDataType accordingly, to support both datatype models. I will send
you a patch, if you're interested.
4. Deprecate the old datatype.
Cheers,
Thomas Koch
[1] I know, that there's a way with diff'ing get_declared_classes, but that's
not nice.
[2] Wouldn't it be a good idea, to name all new created classes ezpXYZ, to get
a new namespace for new classes replacing legacy classes?
