PHP Notice: Undefined index: length

Question

I been figuring out for past few weeks and I been messing around with it and still can't fix it. I not sure what wrong with the coding on length.

Error message is - PHP Notice: Undefined index: length

    // Local variables.
    $output      = '';
    $title       = '';
    $description = '';
            // Local variables by uyghur    
    $iTuneImage              = $options['iTuneImage'];
    $programlink     = $options['programlink'];
    $programTag              = $options['programTag'];
    $iTuneAuthor     = $options['iTuneAuthor'];
    $iTunesummary    = $options['iTunesummary'];
    $iTunesSubtitle  = $options['iTunesSubtitle'];
    $iTunesName      = $options['iTunesName'];
    $iTunesEmail     = $options['iTunesEmail'];
    $iTunesKeywords  = $options['iTunesKeywords'];
    $imageTag        = $options['imageTag'];
    $Audiodiscription        = $options['Audiodiscription'];
    $programTag      = $options['programTag'];
    $linkTAG         = $options['linkTAG'];
    $length          = $options['length'];

Do a `print_r($options);` see if the `length` is actually there (hint: it's not). — Amal Murali, Oct 31 '13 at 18:00
Well, it is undefined. Whereover `$options` comes from, you forgot to declare `length` there. And you didn't show us the relevant code, so difficult to help. — mario, Oct 31 '13 at 18:00

So, how ARE you defining `$options` ? There's your answer. Find it or create it. — Funk Forty Niner, Oct 31 '13 at 18:02

If "length" is really optional, do this (and the same for any other indices of the array).

$length          = isset($options['length']) ? $options['length'] : null;

If you need length, you should handle this as an error (and the same thing for other indices of the array).

if (!isset($options['length'])) { 
    throw new \Exception('You forgot the length!');
}
// the rest of the code...
