Question

I can’t find the reason why my function is not getting all the results. When I go to the page to view the comment I only see the most resent one. If I then delete that comment the next newest comment appears. I’m sure it is something simple that I have not noticed.

function getComments($inPostID=null)
{
    $commentArray = array();

    if (!empty($inPostID))
    {
        //echo " Get comments for the post with the postID of ". $inPostID;
        $stmt = db::connect()->prepare("SELECT * FROM Comments WHERE postID = ? ORDER BY commentDate DESC");
        $stmt->bind_param('i', $inPostID);
        $stmt->execute(); 
        $stmt->bind_result($commentID, $postID, $userID, $commentDate, $commentContent);
        while($stmt->fetch())
        {
            echo"HI ";
            $thisComment = new ViewComment($commentID, $postID, $userID, $commentDate, $commentContent);
            array_push($commentArray, $thisComment);
        }
        $stmt->close();
    }

    return $commentArray;
}

I have figured it out. I was opening a bind statement and then in the ViewComment() function opening another bind statement to get further info from other tables. The fix was to store the bindResults into a array that will be populated by the while and then close that bind statement. Then loop through the amount of results the the while gives in a for loop that calls the ViewComment() with the pramitors being the array from the bindResults array.

Code is below.

function getComments($inPostID=null)
{
    $commentArray = array();
    $tempArray = array();

    if (!empty($inPostID))
    {
        //echo " Get comments for the post with the postID of ". $inPostID;
        $stmt = db::connect()->prepare("SELECT * FROM Comments WHERE postID = ? ORDER BY commentDate DESC");
        $stmt->bind_param('i', $inPostID);
        $stmt->execute();
        $stmt->bind_result($commentID, $postID, $userID, $commentDate, $commentContent);
        while($stmt->fetch())
        {
            $bindResults = array($commentID, $postID, $userID, $commentDate, $commentContent);
            array_push($tempArray, $bindResults);
        }
        $stmt->close();
        $total = count($tempArray);
        for($i = 0; $i < $total; $i++)
        {
            $thisComment = new ViewComment($tempArray[$i][0], $tempArray[$i][1], $tempArray[$i][2], $tempArray[$i][3], $tempArray[$i][4]);
            array_push($commentArray, $thisComment);
        }
    }
    return $commentArray;
}
