Grid View Fetches all records in Yii - php

Question

I am new to Yii. I have did a normal query operation by fixing a criteria in my action. My Grid view fetches particular records from the criteria query, but if I click on second page, it displays all the records again. Please help me in this. I have been stuck here so long. Thanks in advance.
My View:
<div class="form">
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'nimsoft-alerts-form',
'enableAjaxValidation'=>false,
)); ?>
<h1>Missing Hosts List</h1>
<?php //echo $form->errorSummary($model); ?>
<div style="float:left;">
<div class="row">
<?php echo $form->labelEx($model,'host_start_date'); ?>
<?php
Yii::import('application.extensions.CJuiDateTimePicker.CJuiDateTimePicker');
$this->widget('CJuiDateTimePicker', array(
'attribute' => 'host_start_date',
'language' => '',
'model' => $model,
'options' => array(
'mode' => 'focus',
'dateFormat' => 'yy-mm-dd',
//'minDate'=>'0',
'showAnim' => 'slideDown',
),
'htmlOptions' => array(
'style'=>'height:20px;',
'value' => $model->host_start_date,
),
));
?>
<?php echo $form->error($model,'host_start_date'); ?>
</div>
</div><div style="float:left;"> </div>
<div style="float:left;">
<div class="row">
<?php echo $form->labelEx($model,'host_end_date'); ?>
<?php
Yii::import('application.extensions.CJuiDateTimePicker.CJuiDateTimePicker');
$this->widget('CJuiDateTimePicker', array(
'attribute' => 'host_end_date',
'language' => '',
'model' => $model,
'options' => array(
'mode' => 'focus',
'dateFormat' => 'yy-mm-dd',
//'minDate'=>'0',
'showAnim' => 'slideDown',
),
'htmlOptions' => array(
'style'=>'height:20px;',
'value' => $model->host_end_date,
),
));
?>
<?php echo $form->error($model,'host_end_date'); ?>
</div>
</div>
<div class="row buttons">
<?php echo CHtml::button('Search',array('submit' => array('Site/index')));?>
</div>
<?php $this->endWidget(); ?>
<?php //zii.widgets.grid.CGridView
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider'=>$dataProvider,
'enableSorting' => false,
'columns'=>array(
array( // display 'create_time' using an expression

Answer 1

This can be fixed using 'get' for form method instead of the 'post' method you seem to have used.
<div class="form">
<?php $form=$this->beginWidget('CActiveForm', array(
'method' => 'get',
'id'=>'nimsoft-alerts-form',
'enableAjaxValidation'=>false,
)); ?>
And in your action use the following instead of $_POST variables:
$_GET['NimsoftAlerts']
