Use an imagefield for og:image meta tag

I think the drop down need to be in the settings not on each node edit (my user know any things about FB social plugins ;)).

I thinking a easy implementation.

for all
og:title
og:site_name
og:type
og:image
og:description

Provide a field but with http://drupal.org/project/token

+1 for this feature

I think the cleanest way to do that is to have a separate module which fully implements the opengraphprotocol (http://opengraphprotocol.org/). I was hoping to hear from http://drupal.org/project/open_graph.

Could anyone give me some advise on how to change the og metadata now (as long as there's no working module for it)? i would like to change og:title so that it submits the content of a certain cck field. thanks

My thoughts on this one would be to add this on the settings so it is completely configurable based on the current available CCK fields. Here's a rough code:

  $form['fb_social_meta']['fb_social_meta_image'] = array(
      '#title' => t('Image meta source'), 
      '#type' => 'select', 
      '#default_value' => variable_get('fb_social_meta_image', ''),
      '#description' => t('The CCK field to get the meta image from'),
      '#options' => format_content_fields(),
  );

function format_content_fields(){
  $data = array();
  $fields = content_fields();
  
  foreach ($fields as $key => $field) {
    $data[$key] = $field['field_name'];
  }
  
  return $data;
}

This gets all the available CCK fields in your system. This assumes that you only have one image in that CCK imagefield or else you need to do a loop and another set of conditions. You just need to add this using

variable_get('fb_social_meta_image','')

Here's an improved version so you can set the image source per content type:

  $form['fb_social_meta'] = array(
    '#type' => 'fieldset',
    '#title' => t('Open Graph Meta settings'),
    '#collapsible' => TRUE,
    '#collapsed' => FALSE,
  );
  
  $types = content_types();

  foreach ($types as $key => $type) {
    $form['fb_social_meta']['fb_social_meta_image_' . $key] = array(
      '#title' => t('Image meta source for ' . $type['name']), 
      '#type' => 'select', 
      '#default_value' => variable_get('fb_meta_image_' . $key, ''),
      '#description' => t('The CCK field to get the meta image value from'),
      '#options' => format_content_fields(),
    );
  }

and also limit the CCK fields to filefield type only?

function format_content_fields(){
  $data = array(''=>'Disabled');
  $fields = content_fields();
  foreach ($fields as $key => $field) {
    if ($field['type'] == 'filefield') {
      $data[$key] = $field['field_name'];
    }
  }
  return $data;
}

This all sounds really great, to be able to control what Facebook pulls from the node. How/where can I implement the code in reply #6?

Thanks

Thanks ferdi!

Is anyone currently getting # 6 to work with FB social. Running things through FB may be taxing to the server for large node sites. #8 speaks of such and an unfinished OG module.
