私はdrupalモジュールの書き方を学ぼうとしており、簡単な数学モジュールの作成に取り組んでいますhttp://nodeone.se/en/the-math-question-module
GUIは正常に機能していますが、実際の計算に問題があるようです。現在の回答をチェックする前に新しい質問のセットが読み込まれると思うので、正しい回答が得られないようです。
これが私がこれまでに持っているものです：
<?php
/**
* @file
* Tests users on their math skills through a series of question and answers
*/
/**
* Implements hook_menu().
*/
function math_question_menu() {
// add new navigation menu item
$items['math_question'] = array(
'title' => 'Math questions',
'description' => 'Test you math skills with these questions.',
'page callback' => 'drupal_get_form',
'page arguments' => array('math_question_page'),
'access callback' => 'user_access',
'access arguments' => array('administer_site_configuration'),
);
return $items;
}
$val1 = rand(1,10);
$val2 = rand(1,10);
variable_set('val1', $val1);
variable_set('val2', $val2);
/**
* Builds the form for configuring Math Questions.
*/
function math_question_page() {
global $user;
$num1 = variable_get('val1');
$num2 = variable_get('val2');
$total = $num1 + $num2;
variable_set('total',$total);
$form['math_question'] = array(
'#type' => 'item',
'#markup' => 'What is ' . $num1 . ' + ' . $num2 . ', ' .
check_plain($user->name) . '?',
);
$form['answer'] = array(
'#type' => 'textfield',
'#title' => t('Answer'),
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Check my answer'),
);
return $form;
}
function math_question_page_validate($form, $form_state) {
if (empty($form['answer']['#value'])) {
form_error($form['answer'], t('This field is required.'));
}
if ($form['answer']['#value'] ==
variable_get('total')) {
$msg = t('Good job!');
$type = 'status';
}
else {
$msg = t('Try again...');
$type = 'error';
}
drupal_set_message(check_plain($msg), $type);
}
変更されたコード：。。
