所以我才刚刚开始学习 Drupal,所以如果你认为我的做法是错误的,请告诉我。
我有一个名为事件的内容类型。我基本上只是想在主页上输出最新事件的片段。为此,我按照 Drupal 教程Drupal doc's custom module tutorial创建了一个自定义模块
这是我的模块代码
<?php
/**
* Implements hook_block_info().
*/
function latest_event_block_info() {
$blocks['latest_event'] = array(
// The name that will appear in the block list.
'info' => t('Latest Event'),
// Default setting.
'cache' => DRUPAL_CACHE_PER_ROLE,
);
return $blocks;
}
/**
* Custom content function.
*
* Set beginning and end dates, retrieve posts from database
* saved in that time period.
*
* @return
* A result set of the targeted posts.
*/
function latest_event_contents(){
//Get today's date.
$today = getdate();
//Calculate the date a week ago.
$start_time = mktime(0, 0, 0,$today['mon'],($today['mday'] - 7), $today['year']);
//Get all posts from one week ago to the present.
$end_time = time();
//Use Database API to retrieve current posts.
$query = new EntityFieldQuery;
$query->entityCondition('entity_type', 'node')
->entityCondition('bundle', 'event')
->propertyCondition('status', 1) // published == true
->propertyCondition('created', array($start_time, $end_time), 'BETWEEN')
->propertyOrderBy('created', 'DESC') //Most recent first.
->range(0, 1); //ony grab one item
return $query->execute();
}
/**
* Implements hook_block_view().
*
* Prepares the contents of the block.
*/
function latest_event_block_view($delta = '') {
switch ($delta) {
case 'latest_event':
$block['subject'] = t('Latest Event');
if (user_access('access content')) {
// Use our custom function to retrieve data.
$result = latest_event_contents();
$nodes = array();
if (!empty($result['node'])) {
$nodes = node_load_multiple(array_keys($result['node']));
}
// Iterate over the resultset and generate html.
foreach ($nodes as $node) {
//var_dump($node->field_date);
$items[] = array(
'data' => '<p>
<span class="text-color">Next Event</span> ' .
$node->field_date['und'][0]['value'] . ' ' .
'</p>' .
'<p>' .
$node->title . ' ' .
$node->field_location['und'][0]['value'] . ' ' .
'</p>'
);
}
// No content in the last week.
if (empty($nodes)) {
$block['content'] = t('No events available.');
}
else {
// Pass data through theme function.
$block['content'] = theme('item_list', array(
'items' => $items));
}
}
return $block;
}
}
我已将该块添加到一个区域,它在我的模板页面中呈现良好。但是,事件以列表形式输出,这不是我想要的。
这是在 HTML 中呈现块的方式
<div class="item-list">
<ul>
<li class="first last">
<p>
<span class="text-color">Next Event</span> June 23 2016 18:30 - 21:00 </p><p>Cancer Research UK Angel Building, 407 St John Street, London EC1V 4AD
</p>
</li>
</ul>
</div>
因此,假设我正确地处理了整个事情,我该如何修改这个块 html?谢谢!
