Add object_relation attribute type within a php script

Hello,

in this thread, it is explained how to update an entry of an object with a php script:
http://ez.no/community/forum/developer/importing_update_entry_if_it_already_exists

With similar methods, I know how to create a new object in a script with attributes of early any kind of datatypes.

My problem is how to set an 'object relation' attribute?

To add an object relation at the contentobject level, I can use this function :

eZContentObject::addContentObjectRelation  ($toObjectID,
                                                                    $fromObjectVersion = false,
                                                                    $fromObjectID = false,
                                                                    $attributeID = 0)

But this function add a relation between 2 distinct objects,
What i want is to set an attribute of type 'object_relation' or 'object_relation_list'.

To modify an attribute of "simple" datatype I can do something like :

$contentObjectAttribute->setAttribute("data_text", "My new piece of information");
$contentObjectAttribute->store();

with 'object_relation' instead of "data_text".

the function addContentObjectRelation() has a $attributeID parameter which is described like that :
ID of class attribute.
IF > 0 - relations made with attribute ID ("related object(s)" datatype)
0 - regular relations (content object level)

So it seems that I have to use addContentObjectRelation() with the right $attributeID parameter to add
a relation at attribute level, but where can I find the mapping between attributeID and my attribute ?
Am I right ?
And is it enough ? should'nt I also use something like $contentObjectAttribute->setAttribute(...) ?

Many thanks for help

Hi Fabio

Some example code to add objects to an attribute with the datatype object relation list:

$content = $objectRelationListAttribute->content();
$priority = 1;

foreach ( $objectsToRelate as $objectToRelate )
{
    $content['relation_list'][] = eZObjectRelationListType::appendObject( $objectToRelate->attribute( 'id' ), $priority, $objectRelationListAttribute );
    $objectRelationListAttribute->setContent( $content );
    $objectRelationListAttribute->store();
    $priority++;
}

For an attribute with the object relation datatype, you can use:

$objectRelationAttribute->setAttribute( 'data_int', $objectToRelate->attribute( 'id' ) );
$objectRelationAttribute->store();

Content object relations on attribute level will also be made when you use the code above (the datatypes will take care of it).

Hi

thanks for this usefull answer,

I tried the solution for object relation :

$objectRelationAttribute->setAttribute( 'data_int', $objectToRelate->attribute( 'id' ) );
$objectRelationAttribute->store();

And it works fine.

But I can make the solution for object relation list work,
I use a code similar to your suggestion and when I print out the content of $content['relation_list']

$cli->output(print_r($content['relation_list']));


the array is complete and it seems to work,

but when I come bakc to the admin interface, the object is created without the object relation list.

Is there something else I have to add ?

Many thanks
Fabio

Hi Fabio

Does the object attribute contains the relations and the relation list doesn't? Or do the relations show up nowhere?

Hi Kristoff,
here is the result of $cli->output(print_r($content)); after adding relations,
it seems that $content['relation_list'] is updated (like I want) but in the admin interface I can see no relations.

Salut Fabio,

It looks like you put the complete node, you should just put its object id.

Hello,

I did not find exactly why but I have rewrited all the script step by step and your method works
for objetc_relation and object_relation_list.

Many thanks for help.

nice thread

ofcourse, to use eZObjectRelationListType::appendObject you need to have included /kernel/classes/datatypes/ezobjectrelationlist/ezobjectrelationlisttype.php somewhere.

it seems rare to include that file directly. more often, people seem to include

include_once( 'kernel/classes/ezdatatype.php' );

and do something like

eZDataType::loadAndRegisterAllTypes();

which includes ezobjectrelationlisttype.php if it is a valid type.

$2c,
*pike

PS. the print_r output of Fabio Carissimi seems ok. The object get's included in $content['relation_list'][0]['object'] by the appendObject call.

---------------
The class eZContentObjectTreeNode does.

I used the code Kristof mentioned up above (with variable changes) but it seems to crash at the line where the appendObject method is called:

<code>

$content = $positionAttributes['article_selection']->content();
$priority = 1;
$content['relation_list'][] = eZObjectRelationListType::appendObject( $articleObject->attribute( 'id' ), $priority, $positionAttributes['article_selection'] );
$positionAttributes['article_selection']->setContent( $content );
$positionAttributes['article_selection']->store();
$priority++;

</code>

Any ideas why?

Thanks.

Hi Kedar

Can you show us which error you get?
