我目前正在尝试修改一个几乎可以完美满足我的要求但缺少分页的模块。我似乎无法掌握应该如何为其添加分页；大多数 JPagination 示例假设我可以访问查询，但在这个模块（使用 JFactory、JmoduleHelper 和 JModel）中，我看不到查询以添加限制等。
mod_otmininews.php
//No direct access!
defined('_JEXEC') or die;
// Include the syndicate functions only once
require_once dirname(__FILE__).DS.'helper.php';
$doc = &JFactory::getDocument();
$doc->addStyleSheet(JURI::base().'/modules/mod_otmininews/css/layout.css');
$list = modOtMiniNewsHelper::getList($params);
$moduleclass_sfx = htmlspecialchars($params->get('moduleclass_sfx'));
require JModuleHelper::getLayoutPath('mod_otmininews', $params->get('layout', 'default'));
助手.php
//No direct access!
defined('_JEXEC') or die;
require_once JPATH_SITE.'/components/com_content/helpers/route.php';
jimport('joomla.application.component.model');
JModel::addIncludePath(JPATH_SITE.'/components/com_content/models');
abstract class modOtMiniNewsHelper
{
public static function getList(&$params)
{
// Get the dbo
$db = JFactory::getDbo();
// Get an instance of the generic articles model
$model = JModel::getInstance('Articles', 'ContentModel', array('ignore_request' => true));
// Set application parameters in model
$app = JFactory::getApplication();
$appParams = $app->getParams();
$model->setState('params', $appParams);
// Set the filters based on the module params
$model->setState('list.start', 0);
$model->setState('list.limit', (int) $params->get('count', 3));
$model->setState('filter.published', 1);
// Access filter
$access = !JComponentHelper::getParams('com_content')->get('show_noauth');
$authorised = JAccess::getAuthorisedViewLevels(JFactory::getUser()->get('id'));
$model->setState('filter.access', $access);
// Category filter
$model->setState('filter.category_id', $params->get('catid', array()));
// User filter
$userId = JFactory::getUser()->get('id');
switch ($params->get('user_id'))
{
case 'by_me':
$model->setState('filter.author_id', (int) $userId);
break;
case 'not_me':
$model->setState('filter.author_id', $userId);
$model->setState('filter.author_id.include', false);
break;
case '0':
break;
default:
$model->setState('filter.author_id', (int) $params->get('user_id'));
break;
}
// Filter by language
$model->setState('filter.language',$app->getLanguageFilter());
// Featured switch
switch ($params->get('show_featured'))
{
case '1':
$model->setState('filter.featured', 'only');
break;
case '0':
$model->setState('filter.featured', 'hide');
break;
default:
$model->setState('filter.featured', 'show');
break;
}
// Set ordering
$order_map = array(
'm_dsc' => 'a.modified DESC, a.created',
'mc_dsc' => 'CASE WHEN (a.modified = '.$db->quote($db->getNullDate()).') THEN a.created ELSE a.modified END',
'c_dsc' => 'a.created',
'p_dsc' => 'a.publish_up',
'h_dsc' => 'a.hits',
);
$ordering = JArrayHelper::getValue($order_map, $params->get('ordering'), 'a.publish_up');
$dir = 'DESC';
$model->setState('list.ordering', $ordering);
$model->setState('list.direction', $dir);
$items = $model->getItems();
foreach ($items as &$item) {
$item->slug = $item->id.':'.$item->alias;
$item->catslug = $item->catid.':'.$item->category_alias;
if ($access || in_array($item->access, $authorised))
{
// We know that user has the privilege to view the article
$item->link = JRoute::_(ContentHelperRoute::getArticleRoute($item->slug, $item->catslug));
}
else {
$item->link = JRoute::_('index.php?option=com_user&view=login');
}
//$item->title = htmlspecialchars( $item->title );
$item->content= strip_tags(preg_replace('/<img([^>]+)>/i',"",$item->introtext));
$item->content = substr($item->content, 0, $params->get('introtext_limit'));
preg_match_all('/img.+src="([^"]+)"/i', $item->introtext, $matches);
if(empty($matches[1][0])){
$item->images="";
}else{
$item->images= $matches [1] [0];
}
//Show thumbnails
if($params->get('showthumbnails')==1){
if($item->images == ""){
$item->thumbnail = '<img src="'.$params->get('directory_thumbdefault').'" width="'.$params->get('thumbwidth').'" height="'.$params->get('thumbheight').'" alt="'.$item->title.'" />';
}else{
$item->thumbnail = '<img src="' .$item->images.'" width="'.$params->get('thumbwidth').'" height="'.$params->get('thumbheight').'" alt="'.$item->title.'" />' ; //show images
}
}
$item->created_date = $item->created;
}
return $items;
}
}
所有这些代码都创建了一个由
默认的.php
defined('_JEXEC') or die;
?>
<div class="ot_news">
<div class="ot_news_i">
<?php
$count = 0;
foreach ($list as $item) : ?>
<?php $count++; ?>
<div class="ot_items <?php echo ($params->get('count') == $count)?'last-item':''; ?>">
<!-- Show thumbnails -->
<?php if($params->get('showthumbnails') == 1){?>
<div class="ot_thumbs" style="width:<?php echo $params->get('thumbwidth')?>px; height:<?php echo $params->get('thumbheight')?>px;">
<?php if($params->get('enablelinkthumb') == 1) {?>
<a href="<?php echo $item->link; ?>"><?php echo $item->thumbnail ;?></a>
<?php } else { ?>
<?php echo $item->thumbnail?>
<?php }?>
</div>
<?php } else { ?>
<?php echo ''; ?>
<?php } ?>
<!-- End -->
<!-- Show Titles -->
<div class="ot_articles">
<?php if($params->get('showtitle') == 1) { ?>
<div class="ot_title">
<?php if($params->get('enablelinktitle') == 1) { ?>
<a href="<?php echo $item->link; ?>" class="title"><?php echo $item->title; ?></a>
<?php }else{?>
<span class="title"><?php echo $item->title; ?></span>
<?php }?>
</div>
<?php } ?>
<!-- Show Created Date -->
<?php
if ($params->get('show_date') == 1) {
echo '<p class="createddate"><span class="ot_date">';
$date = $item->created_date;
echo JHTML::_('date', $date, $params->get( 'date_format' ));
echo '</span></p>';
}
?>
<!-- Show Content -->
<div class="ot_content"><?php echo $item->content; ?></div>
<!-- Show Readmore -->
<?php if($params->get('readmore') == 1) {?>
<div class="ot_readmore"><a href="<?php echo $item->link; ?>" class="ot_readm"><?php echo JText::_('READMORE') ?></a></div>
<?php }else {?>
<?php echo ''; ?>
<?php } ?>
</div>
</div>
<div class="spaces"></div>
<?php endforeach; ?>
</div>
</div>
<div class="ot-mini-news"><?php echo JText::_('ABOUT_OT_MINI_NEWS'); ?></div>
仅使用 for each 来显示带有照片链接和描述的项目。
所以你可以看到我真的不知道在哪里添加分页代码，我怀疑他们甚至使用其中的一部分进行显示（我在 helper.php 文件中看到了一个 getlist 函数。
任何帮助将非常感激。
