Filter _POST array

[j_70]

I have a form that has checkboxes and two date input boxes that are generated as the result of a query. So each row of a table has a checkbox, and event name, and a start and end date.

A problem that I am having is that the date input boxes are pre-filled with dates. The user can leave the dates as-is, or change them. When the user selects a checkbox, I only want to see the corresponding dates for that row. However, since all the dates for each row are pre-filled, the _POST array for StartDate[] and EndDate[] gives me all the dates.

How do I limit the date arrays based on the checkbox array (id[])?

TIA.

Make each row an array, rather than each column.

Like this:

$dates = array(date('Y-m-d'), date('Y-m-d', strtotime('+1 day')));

if (!isset($_POST['submit'])) {
    echo '<form action="' . $_SERVER['PHP_SELF'] . '" method="post">';
    foreach ($dates as $key => $date) {
        echo '<input type="checkbox" name="row[' . $key . '][checkbox]" />'
           . '<input type="text" name="row[' . $key . '][start_date]" value=' . $date . ' /> to '
           . '<input type="text" name="row[' . $key . '][end_date]" value=' . date('Y-m-d', strtotime($date . ' +1 week')) . ' /><br />';
    }
    echo '<input type="submit" name="submit" />'
       . '</form>';
} else {
    foreach ($_POST['row'] as $row) {
        if (isset($row['checkbox'])) {
            echo $row['start_date'] . ' to ' . $row['end_date'] . '<br />';
        }
    }
}
