好的，我是新來的PHP寫作者，但我被卡住了。我有以下代碼：    add_shortcode( 'mycred_take', 'mycred_pro_render_take_shortcode' );function mycred_pro_render_take_shortcode( $atts, $label = 'Give Away' ) {    extract( shortcode_atts( array(        'user_id' => '',        'confirm' => '',        'amount'  => '',        'unique'  => 0,        'ref'     => 'mycred_take',        'entry'   => '%plural% lose',        'ctype'   => 'mycred_default'    ), $atts ) );    if ( ! is_user_logged_in() || ! function_exists( 'mycred' ) ) return '';    if ( $user_id == '' )        $user_id = get_current_user_id();    // Load essentials    $user_id = absint( $user_id );    $mycred = mycred( $ctype );    // User is excluded = has no balance    if ( $mycred->exclude_user( $user_id ) ) return '';    // Unique check    if ( $unique == 1 && $mycred->has_entry( $ref, 0, $user_id, '', $ctype ) ) return '';    $balance = $mycred->get_users_balance( $user_id, $ctype );    $output = '';    // If button was pushed    if ( isset( $_POST['mycred-take-points-token'] ) && wp_verify_nonce( $_POST['mycred-take-points-token'], 'mycred-deduct-points' . $ref . $ctype ) ) {        // Deduct        $mycred->add_creds(            $ref,            $user_id,            0 - $amount,            $entry        );        // Update balance        $balance = $balance - $amount;    }    // Too low balance    if ( $balance < $amount ) return '';    return $output . '<form action=""  method="post" id="mycred-take-shortcode' . $ref . $ctype . '"><input type="hidden" name="mycred-take-points-token" value="' . wp_create_nonce( 'mycred-deduct-points' . $ref . $ctype ) . '" /><input type="submit"  class="button"  value="' . $label . '" /></form>';}這是一個Wordpress簡碼。我想要在表單提交和數(shù)據(jù)庫更新后刷新頁面。由于此代碼當(dāng)前關(guān)閉且頁面未更新（如果我手動刷新頁面，則數(shù)據(jù)庫已更新，并且會顯示更改）。我嘗試了onSubmit =“ window.location.reload（）”，action =“”代碼，但沒有用。
