joomla分页在每个页面上显示相同的结果

Question

我的文章页面超过5个结果。 每页显示5条结果。 分页出现。 但是，当我转到不同的页面时，每个页面都有相同的5个结果。

我的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;

        //Escape strings for HTML output
        $this->pageclass_sfx = htmlspecialchars($params->get('pageclass_sfx'));


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

如果我在view.html.php中在这里打印$ pagination的内容：

$this->_prepareDocument();

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

我得到以下结果：

在我的模板文件中，我回显了分页：

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

顺便说一句，单击“下一步”确实会将URL更改为...?start=5 。

Answer 1

populateState这一行已被注释掉

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

取消注释将其更改为“ start”参数：

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