How to get some specific field attributes ? was created by bancil

Hi everybody,

How to get field parameters like associated plugins with the field or the state of its "onPrepareContent" attribute ?
Something like $this->item->fields[‘myField’] ->parameters->get(‘valueOfMyField’)...???

thanks !

mmm, not sure what you mean

onPrepareContent is an event not an attribute,
when the event is triggered it alters the text of the field

you want to know which plugins were triggered?

actually the joomla content plugins were never designed to be triggered selectively, this means when you call the event "onPrepareContent", then all content plugins loaded so far will be triggered,

so if field1 triggers all content plugins then if you trigger onPrepareContent for field2 then all plugins will be triggered since field1 has already loaded all of them,

it is possible to trigger content plugins directly like we do for flexicontent fields which are joomla plugins too, but there is an implication that i will not try to explain and confuse you more

If you want to see the available parameter names there are a lot of ways, calling print_r() on parameters OR viewing the XML file of the field OR doing browser's "view page source" in field edit form , or using firebug

Thanks a lot for your explanation, it's very clear.
In fact, I'd like to trigger or not onPrepareContent for my field, depending on the result of a test in my item.php.

In this case disable the CONTENT plugin triggering in the field configuration and use something like

Code:

$dispatcher = &JDispatcher::getInstance();
$limitstart = JRequest::getVar('limitstart', 0, '', 'int');

$field->text = isset($field->display) ? $field->display : '';
$field->title = $this->item->title;
JPluginHelper::importPlugin('content');
$field->slug = $this->item->slug;
$field->sectionid = $this->item->sectionid;
$field->catid = $this->item->catid;
$field->catslug = @$this->item->categoryslug;
$field->fieldid = $field->id;
$field->id = $this->item->id;
$field->state = $this->item->state;

$results = $dispatcher->trigger('onPrepareContent', array (&$field, &$this->params, $limitstart));

$field->id = $field->fieldid;       // restore field id
$field->display = $field->text;   // use text produced by plugins
