Question

Why is my MySQL data not being displayed in my table? Everything seems to work fine except that my data (which is a list of bird names and such) isn’t showing up. I need some fresh eyes who can see where my mistake is, and yes I know that there are probably easier ways to do this, but this is what is required for my assignment, so please don’t offer other ways to do this. All I need is help getting my data to populate in the HTML table. My PHP code is below:

PHP Code

<?php
    $pageTitle = 'Mod06 Pagination| Jason McCoy ';
    include('includes/header.inc.php');
    include ('includes/db_connect.inc.php');

    $display = 8;

    // Determine how many pages there are...

    if (isset($_GET['p']) && is_numeric($_GET['p'])) { // Already been determined.
        $pages = $_GET['pages'];
    } else { 
        $query = "SELECT COUNT(birdID) FROM birds";
        $result = @mysqli_query($dbc, $query);
        $row = @mysqli_fetch_array($result, MYSQLI_NUM);
        $records = $row[0];
    }

    // Calculate the number of pages...

    if ($records > $display) { 
        $pages = ceil($records/$display);
    } else {
        $pages = 1;
    }

    // Determine where in the database to start returning results...

    if (isset($_GET['s']) && is_numeric($_GET['s'])) {
        $start = $_GET['s'];
    } else {
        $start = 0;
    }

    // Sort the columns 
    // Default is birdID

        $sortDefault = 'birdID';

        // Create an array for the columns

        $sortColumns = array('birdID', 'nameGeneral', 'nameSpecific', 'populationTrend');

        // Define sortable query ASC DESC

        $sort =  (isset($_GET['sort'])) && in_array($_GET['sort'], $sortColumns) ? $_GET['sort']: $sortDefault;
        $order = (isset($_GET['order']) && strcasecmp($_GET['order'], 'DESC') == 0) ? 'DESC' : 'ASC';

        // Run the query 

    $query = "SELECT birdID, nameGeneral, nameSpecific, populationTrend FROM birds ORDER BY $order LIMIT $start, $display";
    $result = @mysqli_query($dbc, $query);       
?>

Change this one $row[birdID] to $row['birdID'] for all, you missed ''.
