Question

i have the following array:

    $keyvisual_data = array(
        'video_file'            => $row->field_field_video[0]['rendered']['#item']['uri'],
        'bild_file'             => $row->field_field_bild[0]['rendered']['#item']['uri'],
        'subline_src'           => $row->_field_data['nid']['entity']->field_key_titel['und'][0]['safe_value'],
        'screenreader_src'      => $row->field_field_alt_screenreader[0]['rendered']['#markup'],
        'alt_src'               => $row->field_field_bild[0]['rendered']['#item']['alt']
    );

it might happen that some of the fields are not set, this is okay. in fact i am getting this PHP notice:

Notice: Undefined offset: 0 in bafa_insert_keyvisual() ………..

is it somehow possible to assign a default value to each key in case it is undefined WITHOUT checking each field of the array manually?

thanks for help

Yes, add @ before the field like:

$keyvisual_data = array(
    'video_file'            => @$row->field_field_video[0]['rendered']['#item']['uri'],
    'bild_file'             => @$row->field_field_bild[0]['rendered']['#item']['uri'],
    'subline_src'           => @$row->_field_data['nid']['entity']->field_key_titel['und'][0]['safe_value'],
    'screenreader_src'      => @$row->field_field_alt_screenreader[0]['rendered']['#markup'],
    'alt_src'               => @$row->field_field_bild[0]['rendered']['#item']['alt']
);

and then initialize the nulls:

if($keyvisual_data['video_file'] === null)
    $keyvisual_data['video_file'] = $default_video_file;

etc…
