ich eine dynamische HTML-Tabelle basierend auf der Datenbank Erzeugen der PHP RecursiveIteratorIterator Funktion wie diese unter Verwendung von:Repeat erster Schlüsselwert in PHP RecursiveIteratorIterator
class TableRows extends RecursiveIteratorIterator {
function __construct($it) {
parent::__construct($it, self::LEAVES_ONLY);
}
function current() {
return "<td>".parent::current()."</td>";
}
function beginChildren() {
echo "<tr>";
}
function endChildren() {
echo "</tr>" . "\n";
}
}
Die folgenden foreach Schleife erzeugt jede neue Zeile und übergibt die Daten an den Iterator oben.
foreach(new TableRows(new RecursiveArrayIterator($stmt->fetchAll())) as $k=>$v) {
echo $v;
}
führe ich die PDO $stmt hergestellt, wobei der erste Wert I aus der Datenbank ziehen ist immer die ID der Zeile.
Das alles funktioniert einfach großartig. Nun, das Problem, das ich habe, ist, dass ich einen HTML name Parameter für jedes <td> Element in der current() Funktion des Iterators generieren möchte. Und ich brauche diesen name Parameter, um immer der erste key des aktuellen RecursiveIteratorIterator-Zyklus zu sein (was in meinem Fall der ID-Spaltenwert für jede Zeile wäre).
So etwas wie dies, so kann ich die ID des row in jedem seiner <td> Elemente:
function current() {
return "<td name='".***FIRST ITERATOR KEY VALUE HERE***."'>".parent::current()."</td>";
}
EDIT: Der gesamte Code
class TableRows extends RecursiveIteratorIterator {
function __construct($it) {
parent::__construct($it, self::LEAVES_ONLY);
}
function current() {
/* Here I need to add the value from the ID column to the <td name="... parameter */
return "<td name='".***FIRST ITERATOR KEY VALUE HERE***."'>".parent::current()."</td>";
}
function beginChildren() {
echo "<tr>";
}
function endChildren() {
echo "</tr>" . "\n";
}
}
try
{
$conn = new PDO("mysql:host=$hostname;dbname=$database", $username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$stmt = $conn->prepare("SELECT
id,
ddate,
day,
month,
year,
arrival,
departure,
serial_number,
time_mark,
observations
FROM ROUTS WHERE ddate = '".$datecode."'");
$stmt->execute();
// set the resulting array to associative
$result = $stmt->setFetchMode(PDO::FETCH_ASSOC);
foreach(new TableRows(new RecursiveArrayIterator($stmt->fetchAll())) as $k=>$v) {
echo $v;
}
}
catch(PDOException $e)
{
echo "Error: " . $e->getMessage();
}
$conn = null;
EDIT: Die Beispieltabelle, die ich gerne generiert hätte:

Ich hoffe, jemand kann etwas Licht für mich in dieser Sache werfen.
Und 'RecursiveIteratorIterator :: key()' funktioniert nicht? – dbf
Es funktioniert, aber es gibt den Namen der Spalte für jeden Wert zurück: /. Ich brauche es immer als ersten Schlüssel des aktuellen Zyklus. – Logixor
Ich habe den Test so gemacht: 'function current() { \t Rückgabe"
