Question

我刚刚开始讨论drupal，如果这是一个非常愚蠢的问题，请道歉。我编写了以下模块，但每次尝试访问它时，转到url（http：// localhost：8888 / drupal / doodil_viral_signup）我都会收到拒绝访问的消息。我已经尝试重建权限并禁用和重新启用模块，但它似乎不起作用。

<?php
// $Id$
/**
* @file
* A module to encourage users to sign up.
* This module allows users to sign up to register for the site, and invite their friends to do the same.
*/

/**
* Implements hook_help().
*/
function doodil_viral_signup_help($path, $arg) {
  if ($path == 'admin/help#first') {
    return t('This module allows users to sign up to register for the site, and invite their friends to do the same.');
  }
}

/**
* Implements hook_menu().
*/
function doodil_viral_signup_menu($may_cache = true) {
  $items = array();
  if ($may_cache) {
    $items[] = array(
      'path' => 'doodil_viral_signup',
      'title' => t('Doodil Signup'),
      'callback' => 'doodil_viral_signup_page',
      'access' => TRUE,
      'type' => MENU_CALLBACK,
    );
  }
  return $items;
}

function doodil_viral_signup_page() {
  return drupal_get_form('doodil_viral_signup_page_form');
}

function doodil_viral_signup_page_form() {
  // [input text] First Name
  $form['first_name'] = array(
    '#type' => 'textfield',
    '#title' => t('First Name'),
  );

  // [input text] Last Name
  $form['last_name'] = array(
    '#type' => 'textfield',
    '#title' => t('Last Name'),
  );

  // [input text] Email Address
  $form['email_address'] = array(
    '#type' => 'textfield',
    '#title' => t('Email Address'),
  );

  // [input submit] Sign Me Up
  $form['submit'] = array(
    '#type' => 'submit',
    '#title' => t('Sign Me Up'),
  );
  return $form;
}

function doodil_viral_signup_page_form_submit($form_id, $form_values) {
  $message = 'You have submitted the following information <pre>'.print_r($form_values).'</pre>';
  drupal_set_message(t($message));
}

有谁能告诉我如何解决这个问题？

提前致谢！

除了loganfsmyth之外，执行hook_menu()向您建议的所有内容，它应该是这样的：

function doodil_viral_signup_menu() {
  $items = array();
  $items['doodil_viral_signup'] = array(
    'title' => 'Doodil Signup',
    'page callback' => 'drupal_get_form',
    'page arguments' => array('doodil_viral_signup_page_form'),
    'access callback' => TRUE,
    'type' => MENU_CALLBACK,
  );
  return $items;
}

删除doodil_viral_signup_page()功能。

修改

这只是在我的机器上进行了测试，它的工作非常完美。如果它在您的机器上不起作用，则问题不在此模块中。

function doodil_viral_signup_help($path, $arg) { if ($path == 'admin/help#first') { return t('This module allows users to sign up to register for the site, and invite their friends to do the same.'); } } function doodil_viral_signup_menu() { $items = array(); $items['doodil_viral_signup'] = array( 'title' => 'Doodil Signup', 'page callback' => 'drupal_get_form', 'page arguments' => array('doodil_viral_signup_page_form'), 'access callback' => TRUE, 'type' => MENU_CALLBACK ); return $items; } function doodil_viral_signup_page_form($form, &$form_state) { $form['first_name'] = array( '#type' => 'textfield', '#title' => t('First Name') ); $form['last_name'] = array( '#type' => 'textfield', '#title' => t('Last Name') ); $form['email_address'] = array( '#type' => 'textfield', '#title' => t('Email Address') ); $form['submit'] = array( '#type' => 'submit', '#value' => t('Sign Me Up') ); return $form; } function doodil_viral_signup_page_form_submit($form, $form_state) { $message = t('Your submitted information <pre>!info</pre>', array( '!info' => print_r($form_state['values'], TRUE) )); drupal_set_message($message); }

Answer 2

当你给出的上述代码中的给定（$ form，＆amp; $ form_state）时。您可能会遇到此类错误：

--------------------------------------
warning: Missing argument 2 for 
--------------------------------------

函数中只能有一个参数。

function_name($form)

Answer 3

我得到了同样的错误。

解决这个问题：删除下划线：page_callback，page_arguments和access_callback。

它们应该是“页面回调”，“页面参数”，“访问回调”。（没有下划线）

Answer 4

这段代码全部采用Drupal 5使用的格式。你的标签是drupal 7，所以我假设你想要的是什么？

function doodil_viral_signup_menu() {
  $items = array();
  $items['doodil_viral_signup'] = array(
    'title' => 'Doodil Signup',
    'page callback' => 'doodil_viral_signup_page',
    'access callback' => TRUE,
    'type' => MENU_CALLBACK,
  );
  return $items;
}

表格应为

function doodil_viral_signup_page_form($form, &$form_state) {

提交应该是：

function doodil_viral_signup_page_form_submit($form, $form_state) {
  drupal_set_message(t('You have submitted the following information <pre>!info</pre>', array(
    '!info' => print_r($form_state['values'], TRUE),
  )));
}

使用<pre>是一种丑陋的调试方法。您应该下载devel模块并使用它的函数dsm($form_state['values']);

Drupal“您无权访问此页面。”
