Question

while ($row = mysql_fetch_array($results)) {
    $results_array[$row['post_id']] = $row;   

    $arr = array($row[2] => $row[3]); 

    $location = trim($arr[cp_check_where_to_show_video]);
    $video    = trim($arr[cp_embed_video]);

    echo $video;

    if($location=='Video of the Day')
    { 
        echo $location."\n";
        echo "---";
        echo $video; 
        echo "---";  
    } 
}

Output:
    Video Text
    Video of the Day
    -------
    NULL

Here’s the thing. Suppose I have the code above, the ‘videos’ were derived from the database. So far, i’m having no problem with my queries until I added the if statement.

The first echo outputs the expected results, but inside the if statement “video” becomes NULL. I could get in the if statement and output anything except for the $video.

Could someone please tell what went wrong or could possibly be wrong with the statements above? Weird.

Answer 1

(Really a comment, but adding code so putting in here)

Debug solution 1: Add error reporting; just before the while, add

error_reporting(E_ALL);
ini_set('display_errors', 'on');

and see what that give you.

Debug solution 2:

Could be a case of “Editor inserted wierd character that I can’t see”. Suggestion is to TOTALLY delete the lines inside the if statement (select entire line, hit delete), as well as the lines that reference $video, and retype them manually (no copy / paste). Hidden characters do happen – and the only solution I can think of.
