Examples

Discount between dates

Give a discount of 10% (in this example; see the 0.9) on every ticket-type between 2 dates.

<?php
function your_filter_input_fields( $attr ) {
  if ( time() > strtotime('2019-12-10 00:00:00') && time() < strtotime('2019-12-24 18:00:00') ) {
    foreach ( $attr['tickets'] as $key => $value ) {
      $attr['tickets'][$key]['price'] = number_format( 0.9 * (float) $value['price'], 2, '.', '' );
    }
  }
  return $attr;
}

add_filter( 'fast_events_input_fields', 'your_filter_input_fields', 10, 1 );

Discount if more than 3 tickets

Give a discount of 20% if you order more than 3 Silver tickets.

<?php
function your_filter_input_fields_2( $attr ) {
  foreach ( $attr['tickets'] as $key => $value ) {
    if ( 'Silver' === $value['name'] && 3 < $value['count'] ) {
      $attr['tickets'][$key]['price'] = number_format( 0.8 * (float) $value['price'], 2, '.', '' );
    }
  }
  return $attr;
}

add_filter( 'fast_events_input_fields', 'your_filter_input_fields_2', 10, 1 );

Free ticket

Get 1 free Silver ticket if you order 2 or more Gold (Backstage) tickets.

<?php
function your_filter_input_fields_3( $attr ) {
  foreach ( $attr['tickets'] as $key => $value ) {
    if ( 'Gold (Backstage)' === $value['name'] && 2 <= $value['count'] ) {
      $silver_key = array_search('Silver', array_column($attr['tickets'], 'name'));
      $old_total  = $attr['tickets'][$silver_key]['count'] * (float) $attr['tickets'][$silver_key]['price'];
      $new_price  = $old_total / ( $attr['tickets'][$silver_key]['count'] + 1 );
      $attr['tickets'][$silver_key]['price'] = number_format( $new_price, 2, '.', '' );
      $attr['tickets'][$silver_key]['count']++;
    }
  }
  return $attr;
}

add_filter( 'fast_events_input_fields', 'your_filter_input_fields_3', 10, 1 );

Check password

Check the password against a database table. This requires you to define an input field Password that is used in this snippet. A wrong password or a non-existing user will result in an error. Finding the user is done with the emailaddress.

<?php
function your_filter_input_fields_4( $attr ) {
  // Search for user
  $user = $wpdb->get_row( $wpdb->prepare( "SELECT password FROM put_your_tablename_here WHERE email = '%s'", $attr['email'] ) );
  if ( empty( $user ) ) {
        $attr['errors'] = 'Unknown user';
        return $attr;
  }

  $pwd_key = array_search('Password', array_column($attr['fields'], 'name'));
  if ( ! password_verify( $attr['fields'][$pwd_key]['value'], $user->password ) ) {
    $attr['errors'] = 'Wrong password';
  }
  return $attr;
}

add_filter( 'fast_events_input_fields', 'your_filter_input_fields_4', 10, 1 );
