Unable to save custom metabox data from metabox plugin - php

Question

I am quite new to php and wordpress but have programming knowledge.
i am attempting to save data from these metaboxes in metabox plugin by creating a new custom metabox. this is my code
$tour_rates = get_post_meta( $post->ID, $id, true ) ? maybe_unserialize(get_post_meta( $post->ID, $id, true )) : false;
if ($tour_rates){
foreach ( $tour_rates as $options => $option ) {
$key = 1
$html .= '<tr class="rate-line">';
$html .= '<td>';
$html .= '<span>Opt ' . ($options+1) . '</span>';
$html .= '<input type="hidden" name="' . $id . '[]" class="rwmb-text" size="30" value="">';
$html .= '</td>';
$html .= '<td><input type="text" name="pax_date_'.$key.'[]" class="rwmb-date" size="3" value="'.$option[$key-1].'"></td>';
$html .= '<td><input type="text" name="pax_price_'.$key.'[]" class="pax-price" size="3" value="'.$option[$key-1].'"></td>';
$html .= '</tr>';
}
Now in the save function i have this code. i am able to save only pax-price and not the date along with pax-price. need help and thanks in advance for all your help
static function save( $new, $old, $post_id, $field )
{
$name = $field['id'];
$tour_rates = array();
foreach ( $_POST[$name] as $k => $v ) {
$tour_rates[$k] = array(
$_POST['pax_price_1'][$k],
$_POST['pax_date_1'][$k],
);
}
$new = maybe_serialize( $tour_rates );
update_post_meta( $post_id, $name, $new );
}

Anyways I got the solution. i had made a mistake in the way i was displaying, just in case someone needs a way:
$tour_rates = get_post_meta( $post->ID, $id, true ) ? maybe_unserialize(get_post_meta( $post->ID, $id, true )) : false;
$html = '<div id="tour-rates-info">';
$html .= '<div class="inside">';
$html .= '<div class="rwmb-field">';
$html .= '<div class="rwmb-input">';
$html .= '<table>';
$html .= '<tr>';
$html .= '<th> </th>';
$html .= '<th>'."Departure Date".'</th>';
$html .= '<th>'."Price".'</th>';
$html .= '</tr>';
if ($tour_rates){
foreach ( $tour_rates as $k => $v ) {
$key = 1;
$html .= '<tr class="rate-line">';
$html .= '<td>';
$html .= '<span>Opt ' . ($k+1) . '</span>';
$html .= '<input type="hidden" name="' . $id . '[]" class="rwmb-text" size="30" value="">';
$html .= '</td>';
$html .= '<td><input type="text" name="pax_date_'.$key.'[]" class="rwmb-date" size="9" value="'.$v[0].'"></td>';
$html .= '<td><input type="text" name="pax_price_'.$key.'[]" class="pax-price" size="9" value="'.$v[1].'"></td>';
$html .= '</tr>';
}
Now the save function remains same
static function save( $new, $old, $post_id, $field )
{
$name = $field['id'];
$tour_rates = array();
$tour_rate = array();
foreach ( $_POST[$name] as $k => $v ) {
$tour_rates[$k] = array(
$_POST['pax_date_1'][$k],
$_POST['pax_price_1'][$k],
);
}
echo $tour_rates;
$new = maybe_serialize( $tour_rates );
update_post_meta( $post_id, $name, $new );
}
