将数据从自定义表单保存到数据库

Question

我一直在尝试为drupal网站创建一个非常简单的表单，表单正确显示所有字段。当试图将信息保存到数据库时，我得到一个错误。

我得到：PHP Parse错误：语法错误，意外' - ＆gt;'第286行（T_OBJECT_OPERATOR）

我一直在关注如何在drupal中保存数据的severel指南，并且所有人都同意我应该使用db_insert而不是带有insert语句的db_query，但对于我的生活，我无法理解为什么我得到这个错误。我一直在看几个例子，包括;

https://www.drupal.org/node/1164398

谁能告诉我它为什么不能存钱？我得到错误？

function drupalform_form1_submit($form, &$form_state) {
  $values = array(
    // CONTACT INFO

    'email' => $form_state['values']['email'],
    'phone' => $form_state['values']['phone'],

    // PARTICIPANT 1 VALUES
    'p1name' => $form_state['values']['p1name'],
    'p1nationality' => $form_state['values']['p1nationality'],
    'p1University' => $form_state['values']['p1University'],   
    'p1year' => $form_state['values']['p1year'],  

    // PARTICIPANT 2 VALUES
    'p2name' => $form_state['values']['p2name'],
    'p2nationality' => $form_state['values']['p2nationality'],
    'p2University' => $form_state['values']['p2University'],
