从第50条记录到第75条记录,我只需要25条记录 并且每页需要显示5条记录。
我怎样才能在paginate中做到这一点 示例代码:
$this->paginate = array(
'contain'=>array('User'),
'recursive' => 2,
'order' => array('Profile.winning' => 'DESC'),
'limit' =>5
);
您可以为分页设置条件
function listRecords()
{
$this->paginate = array(
'conditions' => array('Model.id >=' => 50, 'Model.id <=' => 75),
'limit' => 5
);
$this->paginate('Model');
);
然后在模型中:
public function paginateCount($conditions = null, $recursive = 0, $extra = array())
{
if( isset($extra['totallimit']) ) return $extra['totallimit'];
}
改进版,参考: 这将返回正确的总计数,以较小者为准
public function paginateCount($conditions = null, $recursive = 0, $extra = array())
{
$conditions = compact('conditions');
if ($recursive != $this->recursive) {
$conditions['recursive'] = $recursive;
}
unset( $extra['contain'] );
$count = $this->find('count', array_merge($conditions, $extra));
if (isset($extra['group'])) {
$count = $this->getAffectedRows();
}
if (isset($extra['totallimit']) && $extra['totallimit'] < $count) {
return $extra['totallimit'];
}
return $count;
}
public函数paginateCount($conditions=null,$recursive=0,$extra=array())
{
$conditions=紧凑型(“条件”);
如果($recursive!=$this->recursive){
$conditions['recursive']=$recursive;
}
未结算($extra['contain']);
$count=$this->find('count',array_merge($conditions,$extra));
如果(isset($extra['group'])){
$count=$this->getAffectedRows();
}
如果(isset($extra['totallimit'])和&$extra['totallimit']<$count){
返回$extra['totallimit'];
}
返回$count;
}
在CakePHP v2.x中使用maxLimit
public $paginate = array(
// other keys here.
'maxLimit' => 10
);
阅读更多信息。在CakePHP4.x版本中,我们必须像下面这样调用
public function index()
{
$this->loadComponent('Paginator');
$settings = array(
'limit' => 50
);
$prices = $this->Paginator->paginate($this->Prices->find(), $settings);
$this->set(compact('prices'));
}
我正在使用order by,因此我无法在条件中提供“Model.id”。。。我的结果只需要显示最近25张高姿态的记录。获胜是一个完全不同的故事。事实证明,在蛋糕上做这件事并不容易。编辑了答案。不过我不太喜欢。看起来很奇怪,Cake没有内置的核心解决方案……第二个解决方案有效!只需编辑模型和控制器,不幸的是,它必须返回一个totallimit值;如果记录数小于totallimit,则分页仍坚持totallimit值。请添加解释,说明此代码如何解决此问题。
$query = $this->User->find('all', [
'recursive' => 2,
'order' => array('Profile.winning' => 'DESC'),
'limit' => 25,
'offset' => 50
]);
$this->paginate = array(
$query,
'limit' => 5
);
public function index()
{
$this->loadComponent('Paginator');
$settings = array(
'limit' => 50
);
$prices = $this->Paginator->paginate($this->Prices->find(), $settings);
$this->set(compact('prices'));
}
