onContentAfterSave doesn't show custom fields

Question

I created a plugin to send published articles data to external service

class plgSystemVacancypub extends JPlugin
{
    public function onContentAfterSave($context, $article, $isNew)
    {
      // Get custom fields values
      $customFieldnames = FieldsHelper::getFields('com_content.article', $article->get('id'), true);
      $customFieldIds   = array_map(create_function('$o', 'return $o->id;'), $customFieldnames);
      $fmodel           = JModelLegacy::getInstance('Field', 'FieldsModel', array('ignore_request' => true));
      $customFieldValues= $fmodel->getFieldValues($customFieldIds , $article->get('id')); 
       

      // Send to external function
    }
}

But in my article I have some custom fields. First saving the article the $customFieldValues variable is empty. And when I click to Save article once again, custom fields are exists. As I know the custom fields saves after article saving. How can I replace the subsequence of executing "save the custom fields" and my plugin? I want to see custom fields values on first publishing of article.

Answer 1

Well, I didn't found the solution to my problem. But I found another way - correcting the fields plugin (plugins/fields/fields.php), which saves custom fields after article saved. Now I have access to values of all custom fields of first time saving article in onContentAfterSave function.

That event has an undocumented aditional argument $data which holds the saved data!

public function onContentAfterSave($context, $item, $isNew, $data = []){

}

Just in case, set its default to an empty array.

If you check your custom field in the $data it will be there after the event is fired.

For example, for a standard field like the tags, just get them like this:

$thetagssaved = $data['tags'];

For a custom field named "myfield", get it like this:

$myfieldvalue = $data['com_fields']['myfield'];

If you have doubts on what you need to get, output the $data into your log:

error_log(print_r($data, true));
