Question

i’m using JSON to get data and then PHP to display. so…
i’m showing everything available to a person and i want to echo a message when the loop is blank/empty that “there’s nothing available” because right now it just shows a blank screen when there is no data… any ideas??

<? 
foreach($json['available'] as $r) { 
echo '<li><a href="url.php?id='.$r['id'].'">' .$r['item'].'</a></li>'; 
}}
?>

Answer 1

Just use an if statement and check if $json['available'] is empty with empty().

if( empty( $json['available'])) {
    echo '<li>No items are available</li>';
} else {
    foreach($json['available'] as $r) { 
        echo '<li><a href="url.php?id='.$r['id'].'">' .$r['item'].'</a></li>'; 
    }
}
