I am generating a dynamic HTML table based on my DATABASE using the PHP RecursiveIteratorIterator function like this:
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>" . "
";
}
}
The following foreach loop generates each new row and passes the data to the iterator above.
foreach(new TableRows(new RecursiveArrayIterator($stmt->fetchAll())) as $k=>$v) {
echo $v;
}
I execute the PDO prepared $stmt where the first value I pull from the database is always the ID of the row.
All this works just great. Now, the problem I have is that I want to generate an HTML name parameter on each <td> element in the current() function of the iterator. And I need this name parameter to be always the first key of the current RecursiveIteratorIterator cycle (which in my case would be the ID column value for each row).
Something like this, so I can have the ID of the row in each of its <td> elements:
function current() {
return "<td name='".***FIRST ITERATOR KEY VALUE HERE***."'>".parent::current()."</td>";
}
EDIT: The whole code
class TableRows extends RecursiveIteratorIterator {
function __construct($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>" . "
";
}
}
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: The example table that I would like to have generated:

I hope someone can shed some light for me on this matter.
