joomla分页在每一页上显示相同的结果

Question

我有超过5个结果的文章页面。每页显示5个结果。分页显示。然而，当我转到不同的页面时，每个页面都有相同的5个结果。

我getItems（）：

function getItems() 
{ 

    $params = $this->getState()->get('params'); 
    $limit = $this->getState('list.limit'); 
    // 5 

    if ($this->_articles === null && $category = $this->getCategory()) { 
     $model = JModel::getInstance('Articles', 'ContentModel', array('ignore_request' => true)); 
     $model->setState('params', JFactory::getApplication()->getParams()); 
     $model->setState('filter.category_id', $category->id); 
     $model->setState('filter.published', $this->getState('filter.published')); 
     $model->setState('filter.access', $this->getState('filter.access')); 
     $model->setState('filter.language', $this->getState('filter.language')); 
     $model->setState('list.ordering', $this->_buildContentOrderBy()); 
     $model->setState('list.start', $this->getState('list.start')); 
     $model->setState('list.limit', $limit); 

     $model->setState('list.direction', $this->getState('list.direction')); 
     $model->setState('list.filter', $this->getState('list.filter')); 
     // filter.subcategories indicates whether to include articles from subcategories in the list or blog 
     $model->setState('filter.subcategories', $this->getState('filter.subcategories')); 
     $model->setState('filter.max_category_levels', $this->setState('filter.max_category_levels')); 
     $model->setState('list.links', $this->getState('list.links')); 


     if ($limit >= 0) { 
      $this->_articles = $model->getItems(); 
      if ($this->_articles === false) { 
       $this->setError($model->getError()); 
      } 
     } 
     else { 
      $this->_articles=array(); 
     } 

     $this->_pagination = $model->getPagination(); 
    } 
    $filterResult = null; 


    return $this->_articles; 
} 

我填入状态：

      $listOrder = 'ASC'; 
     } 
     $this->setState('list.direction', $listOrder); 

     //$this->setState('list.start', JRequest::getVar('limitstart', 0, '', 'int')); 

     // set limit for query. If list, use parameter. If blog, add blog parameters for limit. 
     if ((JRequest::getCmd('layout') == 'blog') || $params->get('layout_type') == 'blog') { 
      $limit = $params->get('num_leading_articles') + $params->get('num_intro_articles') + $params->get('num_links'); 
      $this->setState('list.links', $params->get('num_links')); 
     } 
     else { 
      $limit = $app->getUserStateFromRequest('com_content.category.list.' . $itemid . '.limit', 'limit', $params->get('display_num')); 
     } 

     $this->setState('list.limit', $limit); 

     // set the depth of the category query based on parameter 
     $showSubcategories = $params->get('show_subcategory_content', '0'); 

     if ($showSubcategories) {

     $this->setState('filter.language',$app->getLanguageFilter());

      $this->setLayout($active->query['layout']);

       $this->intro_items = ContentHelperQuery::orderDownColumns($this->intro_items, $this->columns); 
      }

     $this->assign('maxLevel', $params->get('maxLevel', -1)); 
     $this->assignRef('state', $state); 
     $this->assignRef('items', $items);

     $this->assignRef('children', $children); 
     $this->assignRef('params', $params); 
     $this->assignRef('parent', $parent); 
     $this->assignRef('pagination', $pagination); 
     $this->assignRef('user', $user); 
     $this->_prepareDocument(); 
     parent::display($tpl); 
    } 

如果我打印$的内容分页在view.html.php这里：

$this->_prepareDocument(); 

     echo '<pre>'; print_r($pagination); exit(); 
     parent::display($tpl); 

我得到如下结果：

在我的模板文件，我赞同分页：

<?php echo $this->pagination->getPagesLinks(); ?> 

顺便说一句，点击“下一步”并更改URL到...?start=5。

Answer 1

这条线populateState被注释掉

$this->setState('list.start', JRequest::getVar('limitstart', 0, '', 'int')); 

取消它改变它TOT获得 “开始” 参数：

$this->setState('list.start', JRequest::getVar('start', 0, '', 'int'));
