Question

我有一个像我这样过滤我的分页器的函数：

    public function indextipo() {
    $this->CabAsiento->recursive = 0;
    $tipo = $this->request->data['tipo'];       
    $fecha = $this->request->data['fecha_desde'];
    $this->Paginator->settings=array(
        'paramType' => 'querystring',               
         'limit'=> 1,
         'conditions' => array('CabAsiento.tipo_doc' => $tipo, 'MONTH(CabAsiento.fecha)' => $fecha),
         'order' => array('CabAsiento.id_numero' => 'ASC')
    );
    $this->set('cabAsientos', $this->Paginator->paginate());
    $this->layout = 'ingresos';         
}

它有.ctp。

它可以工作并显示过滤器数据，但是当我尝试下一页时，其他页面会给我：

未定义的索引：tipo [APP \ Controller \ CabAsientosController.php，第35行]

未定义索引：fecha_desde [APP \ Controller \ CabAsientosController.php，第36行]

导致参数丢失。如何保存或存储通过表单搜索发送的参数：

            <div class="portlet-body">
            <?php echo $this->Form->create(false, array('action' => 'indextipo','id' => 'form-login1')); ?> 
            <fieldset>
            <?php
                echo $this->Form->input('fecha_desde', array('id'=>'fecha_desde1', 'type' => 'date','dateFormat' => 'M','class' => 'span3'));
                $arrCategory=array("ing"=>"Ingreso","egre"=>"Egreso","trasp"=>"Trapaso");
                echo $this->form->input('tipo',array('type' => 'select','options'=> $arrCategory)); 
            ?>
            </fieldset>
        </div>
        </div>
        </div>
    </div>
    </div>
    <div class="modal-footer">
        <?php 
            echo $this->Form->button("<i class='icon-plus'></i> Buscar", array('type' => 'submit','id' => 'submit_id', 'class' => 'btn green', 'escape' => false, 'aria-hidden'=>"true"));
            echo $this->Form->end();
        ?>      
    </div>

Answer 1

我认为您所寻找的内容可以使用Search Plugin进行设置。

您的控制器应如下所示：

class ArticlesController extends AppController {

    public $components = array(
        'Search.Prg'
    );

    public function find() {
        $this->Prg->commonProcess();
        $this->Paginator->settings['conditions'] = $this->Article->parseCriteria($this->Prg->parsedParams());
        $this->set('articles', $this->Paginator->paginate());
    }
}

在访问这些数据之前，您必须检查它们的存在。

public function indextipo() {
    $settings = array(
        'paramType' => 'querystring',
        'limit' => 1,
        'order' => array('CabAsiento.id_numero' => 'ASC')
    );
    //Check if data are submited
    if ($this->request->is('post')) {
        $tipo = $this->request->data('tipo');
        $fecha = $this->request->data('fecha_desde');
        $settings['conditions'] = array('CabAsiento.tipo_doc' => $tipo, 'MONTH(CabAsiento.fecha)' => $fecha);
    }

    $this->CabAsiento->recursive = 0;
    $this->Paginator->settings = $settings;
    $this->set('cabAsientos', $this->Paginator->paginate());
    $this->layout = 'ingresos';
}

好了几个信息之后做了：

if(isset($this->request->data['tipo']) && isset($this->request->data['fecha_desde']) && isset($this->request->data['numero']))
    {
        $this->Session->write('tipo', $this->request->data['tipo']);    
        $this->Session->write('fech', $this->request->data['fecha_desde']); 
        $this->Session->write('num', $this->request->data['numero']);   
    }

    $tipo = $this->Session->read('tipo');   
    $fecha = $this->Session->read('fech');

所以我正在使用会话数据来保存我的搜索参数，如果我要更改页面或其他类型的搜索，这些数据将会保留。

CakePHP将参数存储到paginator设置中
