Drupal - 找不到自定义模块的页面

Question

I'm fairly new to Drupal and just made my first module wich shows a form. In the hook_menu(), I set $items['form'], as you can see below. While I navigate to mysite.com/form, it doesn't show me anything, except for the theme and: Page not found, The requested page "/form" could not be found.

I tried to clear my cache, to give my module a different name, made sure my module is enabled, nothing helps. Does anyone knows what the problem might be? The code from the .module file is right here:

<?php 

//implements hook_permission()
function form_example_permission() {
  return array(
    'Submit form_example' => array(
      'title' => t('Submit form_example'),
      'description' => t('Submit the form_example form'),
    ),
  );
}


//implements hook_menu()
function form_example_menu() {
  $items['form'] = array(
    'title' => 'My Example Form',
    'type' => MENU_NORMAL_ITEM,
    'acces' => TRUE,
    'page callback' => 'drupal_get_form()',
    'page arguments' => array('form_example_form'),
    'acces arguments' => array('acces content'),
  );

  return $items;
}

//implements hook_form()
function form_example_form($form, &$form_state) {
  $form['mynumber'] = array (
    '#type' => 'textfield',
    '#title' => t('My Number'),
    '#size' => 10,
    '#maxlength' => 10,
    '#required' => TRUE,
    '#description' => t('Please enter a valid number'),
  );

  $form['mytextfield'] = array(
    '#type' => 'textfield',
    '#title' => t('My Textfield'),
    '#size' => 60,
    '#maxlength' => 128,
    '#required' => TRUE,
  );

  $form['mytext'] = array(
    '#title' => t('My Textarea'),
    '#type' => 'textarea',
    '#description' => t('Enter some text'),
    '#default value' => '',
    '#required' => TRUE,
  );

  $form['submit'] = array(
    '#type' => 'submit',
    '#value' => t('Add item'),
  );

  return $form;
}

Answer 1

'page callback' => 'drupal_get_form() is wrong, you need to remove brackets from function name. The right implementation will be page callback' => 'drupal_get_form . And also acces => TRUE is wrong, it must be 'access callback', and if you set fixed TRUE value then you don't need to specify access arguments key. Because access callback return TRUE anyway.

UPDATE: Example:

function form_example_permission() {
  return array(
    'submit form_example' => array(
      'title' => t('Submit form_example'),
      'description' => t('Submit the form_example form'),
    ),
  );
}


//implements hook_menu()
function form_example_menu() {
  $items['form'] = array(
    'title' => 'My Example Form',
    'type' => MENU_NORMAL_ITEM,
    'access callback' => 'user_access',
    'page callback' => 'drupal_get_form',
    'page arguments' => array('form_example_form'),
    'access arguments' => array('submit form_example'),
  );

  return $items;
}

(you had a typo in you code) Don't forget to flush the cache.

Answer 2

Please change speling a acces to access and change the drupal_get_form() to drupal_get_form and after clear a caches

function form_example_menu() {
  $items['form'] = array(
    'title' => 'My Example Form',
    'type' => MENU_NORMAL_ITEM,
    'access' => TRUE,
    'page callback' => 'drupal_get_form',
    'page arguments' => array('form_example_form'),
    'access arguments' => array('access content'),
  );

  return $items;
}
