cakephp-2.3 – cakephp paginator helper在删除最后一页的最后一条记录时显示错误

如果从最后一页删除最后一条记录,我只想将其重定向到最后一条索引.
请帮我这样做.

<?php                       
    echo $this->Paginator->prev
      ($this->Html->image('prev.png'),array('escape' => false),array(),null,array('class' => 'prev'));
    echo $this->Paginator->counter
      ('Page {:page} of {:pages},Total Records {:count}');                     
    echo $this->Paginator->next($this->Html->image
      ('next.png'),array('class' => 'next'));
 ?>

但是,在$this-> request-> params [‘paging’]中可以使用分页参数的文档不正确,因为这些是在抛出异常后定义的. (两个月前CakePHP 2.4.x中已修复此问题)

因此,要获得您想要的效果,您可以在控制器中执行以下操作：

public function index() {
    try {
        $paginatedData = $this->Paginator->paginate();
    } catch (NotFoundException $e) {
        //get current page
        $page = $this->request->params['named']['page'];
        if( $page > 1 ){
            //redirect to previous page
            $this->redirect( array( "page" => $page-1 ) );
        }else{
            $paginatedData = array(); //no data to paginate so use empty array()
                                      //you will have to check for this in the view and no longer display the pagination links,since they will NOT be defined
        }
    }
}
