Question

我正在构建一个drupal站点，我希望管理员能够将目标输入到drupal数据库的表中，然后可以输出给其他用户完成。

创建输入和表格的表单，但是在按下提交时，值不会添加到表格中，我不确定原因。

我从我连接到我的网站的模块中获得以下代码。我认为问题发生在我创建字段的顶部，或者在我提交值时在底部。我真的不确定。

谁能告诉我哪里出错了以及如何解决？

<?php

function achievementList_init() {
if(!(db_table_exists('achievements'))) {
    $achvmnt_list_schema = array(
        'description' => 'Achievement Fields',
        'fields' => array (
            'achvmntID' => array('type' => 'int', 'unsigned' => TRUE, 'AUTO_INCREMENT' => TRUE, 'not null' => TRUE),

            'achvmntName' => array('type' => 'varchar', 'length' => 256, 'not null' => TRUE, 'default' => ''),

            'achvmntDesc' => array('type' => 'varchar', 'length' => 256, 'not null' => TRUE, 'default' => ''),

            'achvmntPts' => array('type' => 'int', 'unsigned' => TRUE, 'not null' => TRUE),

    ));
    db_create_table('achievements', $achvmnt_list_schema);

}
if($form_state['values']['description'] = '') {
    form_set_error('name', t('Please describe the achievement!'));

    form_set_error('name', t('Achievement must be worth points!'));

function achievementList_submit($form, &$form_state) {
db_insert('achievements')
->fields(array(

->execute();
}

Answer 1

您应该在“.install”文件中的HOOK_SCHEMA下添加SQL表创建代码。
启用模块确认后，您在mysql下创建了表根据要求。
之后您的代码应该可以正常工作。[删除SQL表创建代码来自HOOK_INIT]

您可以参考Drupal Example module
