Hi Izwan,

The purpose of using a "Field::Subject" type component is that it will display the options in a subject tree format where you can click the add button next to the subject would want to choose.  This may make it easier to use that a select box, particular where you might want to select multiple options.  Using the "Field::Subject" type component will break for any type of field other than the "subject" type.  For "namedset" type field you should use a plain component:

<component>
  <field ref="YOUR_NAMEDSET_FIELD"/>
</component>

Although using "Manage Metadata Fields" via the web interface can cause some complications, you should be able to create at least basic versions of all types of field.  You do need to make sure you deploy the field, once you have finished configuring it.  You may also need to reload your repositories configuration using the "Reload Configuration"  and "Update Database" buttons in the "Config. Tools" tab of the Admin page.  However, I would normally expect that to occur as part of the action that deploys the new field you have configured.

It would be useful if you could provide the exact error message. "Undefined or invalid function" is a rather generic error and easy to cause with only minor configuration mistakes.

Does all metadata field need to add type like subject? - <component type="Field::Subject">

I just add another new one with type namedset but got Undefined or invalid function error in log.

I already create the file in the namedsets folder.

Btw, forgot to mention, I create the field from the web interface - /cgi/users/home?screen=MetaField::Listing&dataset=eprint#t

Oh yeah, this work.

Thanks John.

I just need to edit the page phrases for the search form. I just copy it from subjects.

Thanks for replying me, John and David.

Hi,

Try this:

<component type="Field::Subject">
  <field ref="campuses" />
</component>

Sorry for a short reply - I'm on my phone!

Cheers,

Subject: Re: [EP-tech] {Suspected SPAM} Undefined or invalid function when add new dataset field

 

Hi Izwan,

You say that campuses is a new dataset but you have added the field as type 'subject'.  This is not going to work you probably want to use type 'dataobjref':

https://wiki.eprints.org/w/Dataobjref_field

If campuses are actually specified in your subjects tree then you could use a field of type 'subject'.  However, you would need to make sure you have section of you subject tree that contains all your campuses and then specify this parent subject's id this under the 'top' attribute of the subject typed field.

Dear all

Just add a new dataset - campuses to our repository. The type is subject. I already run epadmin update dan upgrade.

However, when I add <component><field ref="campuses" /></component> in our default page, it will show an error with the log indicated as below:
