我爲我自己的組件創建了joomla分頁，並且它爲joomla 2.5工作正常，並且我使用了相同的joomla 3.0數據顯示，並且分頁也正確顯示，但是問題是當我點擊任何分頁號。對於下一頁或上一頁，其不工作的表單仍保留在同一頁上。Joomla分頁不適用於joomla 3.0
這裏是我用於創建分頁的代碼。

任何能幫我什麼是錯還是什麼我缺少
我也曾嘗試JModelList但沒有任何變化。同樣的問題 –
嘗試從您的模型類中移除方法getPagination（）。您重寫並因此通過重寫JModelList類中的getPagination（）方法來排除核心分頁功能已爲您完成的所有工作。您還需要將_buildQuery（）方法重命名爲getListQuery（），以確保父類可以訪問原始數據以進行分頁。 –
我已經刪除了getPagination（）並且還將_buildQuery（）重命名爲getListQuery（），但仍然沒有效果。相同的空白頁面，但當我刪除'__construct（）'一切工作正常，但沒有分頁。 –
