You’re doing well, just apply a filtering function to each row you recieve:<\/p>\n

\/\/ SO UPDATE THE QUERY TO ONLY PULL THAT SHOW'S DOGS\n$query = \"SELECT * FROM result\nWHERE first IS NOT NULL\";\n\n$result = mysqli_query($connection, $query);\n\nif (!$result) {\n\n    trigger_error(\"Query Failed! SQL: $query - Error: \". mysqli_error($connection), E_USER_ERROR);\n\n} else {\n\n    \/\/ Fetch results into array\n    $data = mysqli_fetch_all($result, MYSQLI_ASSOC);\n\n    \/\/ If results array is not empty\n    if ($data) {\n\n\n        echo '<table class=\"table\" border=\"0\"><\/div>\n        <tr>\n          <td>\n            <strong><?php echo $class_name ?><\/strong> - <h6>Entries: <?php echo $entries ?> Absentees: <?php echo $absentee ?><\/h6>\n          <\/td>\n          <td><\/td>\n        <\/tr>';\n\n        \/\/ Now let's walk through every record\n        array_walk($data, function($dogRecord) {\n\n            \/\/ Here we apply array_filter to each dog record, so that empty values (i.e. those evaluating to false) are filtered out\n            $dogRecord = array_filter($dogRecord);\n\n\n            \/\/ Now loop throw $dogRecord to build table\n\n            $collation = [\n                'DCC' => 'DCC',\n                'RDCC' => 'RDCC',\n                'BCC' => 'BCC',\n                'RBCC' => 'RBCC',\n                'BOB' => 'BOB',\n                'BP' => 'BOB',\n                'BJ' => 'BOB',\n                '1ST' => 'first',\n                '2ND' => 'second',\n                '3RD' => 'third',\n                'RES' => 'RES',\n                'VHC' => 'RES'\n            ];\n\n            foreach ($dogRecord as $property => $value) {\n\n                echo '<tr>\n                    <td>'.$collation[$property].'<\/td>\n                    <td>'.$value.'<\/td>\n                <\/tr>';\n\n            }\n\n        });\n\n\n        echo '<\/table>';\n    }\n\n}\n<\/code><\/pre>\n
Note that instead of simple foreach<\/code> loop I’m using array_walk<\/code> function. This is because since you extract variables for each record, you want undeclared (i.e. unoccupied) varables every time.<\/p>\n<\/p><\/div>\n
