Question

I’m trying to fill an array and I want to add some logic in it so it won’t give me back errors…

Here is the code:

$entries_mixes = array();

foreach ($entries_query->result_array() as $entry) {


   $entries_mixes[] = array('title' => $entry['title'],
        'body' => $entry['body'],
        'author' => $entry['author'],
        'date_time' => $entry['date_time'],
        'id' => $entry['id'],
        'mix_name' => $mix['name'],
        'photo_name' =>$photo['name']
    );


}

what I want to do is to be able to check if some of the variables exist before I put them into the array….
so for example if(isset($mix['name'])) then insert to array or else do nothing

The point is not having undeclared variables trying to be inserted to my array cause it gives back errors…thanks!

You can use the ? : ternary operator:

  $entries_mixes[] = array( 
       'title' =>  (isset($entry['title'])  ? $entry['title']  : null),
       'author' => (isset($entry['author']) ? $entry['author'] : null),
  ...

alternatively, use empty() for the check
