drupal菜鸟笔记之向drupalSettings添加数据

在drupal中，我们可以通过API接口向前端提供数据，也可以将数据放入drupalSettings中，有前端通过JS获取数据。即通过预处理函数在数据传递给主题模板之前进行增加或修改数据。

官方文档参考：
预处理函数

方案1：

/*** Implements hook_preprocess_page().*/
function ixtend_report_preprocess_page(array &$variables) {//1. 条件判断//2. 数据获取$requested_vaials_diagnosis = ...$requested_month = ...//3. 赋值$variables['#attached']['library'][] = 'ixtend_report/ixtend_report-js';$variables['#attached']['drupalSettings']['ixtend_report']['chart_data'] = json_encode(['requested_vaials_diagnosis' => $requested_vaials_diagnosis,'requested_month' => $requested_month]);
}

方案2：

/*** Implements hook_page_attachments().*/function ixtend_report_page_attachments(array &$attachments){//1. 条件判断//2. 数据获取$requested_vaials_diagnosis = ...$requested_month = ...//3. 赋值$attachments['#attached']['library'][] = 'ixtend_report/guest';$attachments['#attached']['drupalSettings']['ixtend_report']['chart_data'] = ['requested_vaials_diagnosis' => $requested_vaials_diagnosis,'requested_month' => $requested_month];
}

ps:打开相应页面，在浏览器控制台（console）中输入drupalSettings后回车即可看到drupalSettings下的数据。
