使用带有Wordpress的foreach的未定义索引

Question

Ok, my long day is catching up with me... I am trying to list out custom post meta fields and keep getting Notice: Undefined index: related-headline in... Here is what the array looks like:

Array ( [0] => Array ( [0] => Array ( [related-headline] => Street Outlaws Turbo Rotary Mazda RX-7 – OKC NoPrep [related-url] => //localhost:3000/street-outlaws-turbo-rotary-mazda-rx-7-okc-noprep/ [related-image_id] => 78055 [related-image] => //localhost:3000/wp-content/uploads/2015/12/lucky-to-be-alive-distracted-dri.jpg ) [1] => Array ( [related-headline] => In the Driver’s Seat: Shane vs. The Reaper | Street Outlaws [related-url] => //localhost:3000/in-the-drivers-seat-shane-vs-the-reaper-street-outlaws/ [related-image_id] => 78048 [related-image] => //localhost:3000/wp-content/uploads/2015/12/ford-f350-vs-dodge-ram-vs-chevy.jpg ) ) ) 

Here is my code:

$entries = get_post_meta( get_the_ID(), 'ss-related-posts' );
// print_r($entries);

foreach ( (array) $entries as $key => $entry ) {
    $title = '';
    $title = $entry['related-headline'];
    echo $title;
}

I know I am missing something simple here so any help would be most appreciated.

Answer 1

I got it to work by simply adding TRUE to the function call as suggested in the comments by cale_b:

$entries = get_post_meta( get_the_ID(), 'ss-related-posts', TRUE );

foreach ( (array) $entries as $key => $entry ) {
    $title = $url = $img = "";
    $title = $entry['related-headline'];
    $url = $entry['related-url'];
    $img = $entry['related-image'];

    echo $title . "<br>" . $url . "<br>" . $img . "<br>";
}
