Yes, we can!

Here's a sample about creating class and attributes using php.

Btw, welcome to ez community forum.

I'll try now... If there are further questions, I'll come back :)

There I am, I was on the wrong way...

Adding new attributes to an existing eZContentClass is possible with the solution you explained before.

But I need to add new attributes programmatically to eZContentObject.

I'd like to try with
$new_attribute = eZContentObjectAttribute::create($contentclassAttributeID, $contentobjectID);
but where do I get "$contentclassAttributeID" from?

Thank you!

But it seems only work for existing attributes? I need to create new attributes.

Any idea or short snippet?

I'm not sure where to get the 'contentclassAttributeID' from.

Thank you, I've tested your advice now.

I have a class 'cars_article' and I want to create a new attribute 'keywords'.

I have done like this:

class MyTestingHandler extends eZContentObjectEditHandler
{
  function publish($contentObjectID, $contentObjectVersion)
  {
    $articleClass = eZContentClass::fetchByIdentifier('cars_article');
    
    if (is_object($articleClass))
    {
      $contentClassID = $articleClass->attribute('id');
      $classVersion = $articleClass->attribute('version');

      $DataTypeString = 'ezstring';
      $new_attribute = eZContentClassAttribute::create($contentClassID, $DataTypeString);
                
      $new_attribute->setAttribute('version', $classVersion);
      $new_attribute->setAttribute('name', 'Keywords');
      $new_attribute->setAttribute('is_required', 0);
      $new_attribute->setAttribute('is_searchable', 0);
      $new_attribute->setAttribute('can_translate', 0);
      $new_attribute->setAttribute('identifier','keywords');
                
      $dataType = $new_attribute->dataType();
      $dataType->initializeClassAttribute($new_attribute);
      $new_attribute->store();
    }

I fetched the object like this:

$object = eZContentObject::fetch($contentObjectID);

2 problems I got:

1. In backend creating new article of class 'cars_article' I have now a new field 'keywords'. BUT if I want to add keywords to an existing article, I don't have the field. What's wrong here?
2. How can I add keywords into the article programmatically?

I have a knot in my brain :D

Thanks & greetings
Tom
