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

You should use "isset" function to check the existence of the field, and infact its a good coding practice..

$keyvisual_data = array(
      'video_file' => isset($rowWrapper->getVideoFile()) ? $rowWrapper->getVideoFile() : "any default value",
       ...
 );

or you can use it in this way :

if(isset($rowWrapper->getVideoFile()))
{  
     $row['video_file'] = $rowWrapper->getVideoFile();
}
else {
   $row['video_file'] = "";
}
