How to avoid PHP Notice “Undefined offset: 0” without checking each field of array

Question

i have the following array:

    $keyvisual_data = array(
        \'video_file\'            => $row->field_field_video[0][\'rendered\'][\'#item\'][\'uri\'],         


        

Answer 1

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...
