これは以前の質問から構築されています: https://stackoverflow.com/questions/15534272/interpreting-the-day-of-a-datetime-and-putting-it-into-a-relevant-div

本質的に、私はこのテーブルを持っています:

Events Table
EventID | Start               | End                 |  Details
1       | 2013-03-18 09:00:00 | 2013-03-18 10:00:00 |  Event is in room 6
2       | 2013-03-18 10:00:00 | 2013-03-18 11:00:00 |  Event is in room 3

そしてこの列：

<div class="timetable-column-first">
    <div class="timetable-row-start">Time</div>
    <div class="timetable-row">9:00am</div>
    <div class="timetable-row">10:00am</div>
</div>

<div class="timetable-column">
    <div class="timetable-row-start">Monday</div>
    <div class="timetable-row" id="mon-9"></div>
    <div class="timetable-row" id="mon-10"></div>
</div>

必要な情報を取得するために、次の php クエリを作成しました。

function getEvents($weekNumStart, $weekNumEnd){
    $mysqli = new mysqli(DB_SERVER, DB_USER, DB_PASSWORD, DB_NAME);
    if (!$mysqli) {
        die('There was a problem connecting to the database.');
    }
    else {
        if ($weekNumEnd == '') {
            $weekNumEnd = $weekNumStart;
        }
        $query = $mysqli->prepare("SELECT EventID, DAYOFWEEK(Start) AS wday, Events.Start, HOUR(Start) AS sHour, HOUR(End) AS eHour, Events.End, Details, StartName FROM Events, Week WHERE StartName >= '$weekNumStart' AND StartName <= '$weekNumEnd' AND Events.Start >= StartWeek AND Events.Start <=EndWeek;");
        $query->execute();
        $query->bind_result($eventID, $dayofweek, $startDateTime, $startHour, $endHour, $endDateTime, $weekName);
        while ($query->fetch()){
            echo $eventID, $dayofweek, $startDateTime, $startHour, $endHour, $endDateTime, $weekName;
        }
    }
    $mysqli->close();
}

問題は、このクエリが、ヘッダーに含まれる添付の php ファイル /functions.php で実行されることです。

この行を変更する方法がわかりません：

echo $eventID, $dayofweek, $startDateTime, $startHour, $endHour, $endDateTime, $weekName;

各配列を元のindex.phpに返すため、jqueryを使用してdiv IDの列と行に挿入できます。たとえば、詳細は div で次のようになります。

<div class="timetable-column">
    <div class="timetable-row-start">Monday</div>
    <div class="timetable-row" id="mon-9">1 - Event is in room 6</div>
    <div class="timetable-row" id="mon-10">2 - Event is in room 3</div>
</div>

現状では、私の関数は機能し、サーバーからのすべての個々のデータをエコー バックします。

index.php ページでは、次のように呼び出します。

getEvents($weekNumStart, $weekNumEnd);

エコーの代わりに配列を返すことを考えましたが、それは1行だけを返すのではないでしょうか? そして、リストを含むindex.phpページでそれを拾ったとき($the data here) = getEvents($weekNumStart, $weekNumEnd);、最初のイベントだけが送り返されますか?

このようなことを行うための私の典型的なモデルは次のとおりです。

function getEvents($weekNumStart, $weekNumEnd){
    // I'm moving the SQL up here just so it's out of the way for a minute;
    $sql_str = "SELECT EventID, DAYOFWEEK(Start) AS wday, Events.Start, HOUR(Start) AS sHour, HOUR(End) AS eHour, Events.End, Details, StartName FROM Events, Week WHERE StartName >= '$weekNumStart' AND StartName <= '$weekNumEnd' AND Events.Start >= StartWeek AND Events.Start <=EndWeek";


    $mysqli = new mysqli(DB_SERVER, DB_USER, DB_PASSWORD, DB_NAME);
    if (!$mysqli) {
        die('There was a problem connecting to the database.');
    }
    else {
        if ($weekNumEnd == '') {
            $weekNumEnd = $weekNumStart;
        }
        $query = $mysqli->prepare($sql_str); // I moved the string above just for clarity
        $query->execute();
        $query->bind_result($eventID, $dayofweek, $startDateTime, $startHour, $endHour, $endDateTime, $weekName);

        // LINE ADDED:
        $data_arr = array();
        while ($query->fetch()){
            // I'm creating an associative array to sort each result by day of
            // the week
            $data_arr[$dayofweek] = array(
                $eventID, $dayofweek, $startDateTime, 
                $startHour, $endHour, $endDateTime, $weekName
            );
            /* Example of what the object would look like with your events in it.
            ['Monday' => [[
                   1, "Monday", "2013-03-18 09:00:00", 
                   "09", "10", "2013-03-18 10:00:00",
                   "Event is in room 6"
            ], [
                   2, "Monday", "2013-03-18 10:00:00", 
                   "10", "11", "2013-03-18 11:00:00",
                   "Event is in room 3"
            ]]];
             */
        }
        $mysqli->close(); // a little redundant, but meh
        return $data_arr; // returns each of your results as an array within an array
    }
    $mysqli->close();

}

次に、 getEvents() 関数を呼び出している場所から、次のようにします。

$data = getEvents($weekNumStart, $weekNumEnd);

$html = '';
$firstCol = '';
$secondCol = '';

// for each day in the data array:
foreach($data as $day) {
    $firstCol .= '<div class="timetable-column-first">'
           . '<div class="timetable-row-start">Time</div>';
    $secondCol .= '<div class="timetable-column">'
           . '<div class="timetable-row-start">' . $day . '</div>';

    $timeStartRow = '';
    $detailsRow = '';
    for($i = 0; $i < count($data[$day]); $i++) {
        $startHour = $data[$day][$i][3];
        $details = $data[$day][$i][6];

        // build the content rows within the first column
        $timeStartRow .= '<div class="timetable-row">' 
                      . $startHour                         // append each start hour
                      . '</div>';

        // build the content rows within the second column
        $detailsRow .= '<div class="timetable-row" id="' 
                    . $day . '-' . $starHour . '">'        // create the id
                    . $details                             // deats!
                    . '</div>';
    }
    $timeStartRow .= '</div>'; // close off .timetable-column-first
    $detailsRow .= '</div>'; // close off .timetable-column

    $html .= $firstCol . $timeStartRow . $secondCol . $detailsRow;
    $firstCol = '';
    $secondCol = '';
} 

echo $html; // I can't guarantee it will work, but it'll be 90% there :]

これが役に立ったことを願っています。他に何もない場合は、私が目指している全体的なアイデアをスキャンしてください。幸運を！
