Answer1:

Try this (please replace the required values, especially ACTION_NAME) -

Change in view file -

<?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save' ); ?>

to

<?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save', array('id' => 'text_form_submit') ); ?>

Write this at the end of the view file -

<script> $(document).ready(function() { $('#text_form_submit').click(function(ev) { ev.preventDefault(); $.ajax({ type: 'GET', dataType: 'JSON', url: '<?php echo Yii::app()->createUrl("text/ACTION_NAME"); ?>', success:function(data){ if(data !== null) { $('#Text_group').val(data); $('#text-form').submit(); } }, error: function() { alert("Error occured!!!."); }, }); return false; }); }); </script>

In TextController -

Create a new action (same as what is mentioned in replacement to ACTION_NAME) -

public function actionACTION_NAME() { $groupNumber = Text::model()->maxIdNote(); echo json_encode($groupNumber); exit(); }

Answer2:

this is new my code

_form.php

<div class="form"> <?php $form=$this->beginWidget('CActiveForm', array( 'id'=>'text-form', // See class documentation of CActiveForm for details on this. 'enableAjaxValidation'=>TRUE, // 'action'=>$this->createUrl('TextController/performAjaxValidation'), 'focus'=>array($model,'group'), // 'clientOptions'=>array( // 'validateOnChange'=>true, // the default. validate when input changes // 'validateOnType'=>'true', // validate with EVERY keystroke, hooray! // 'validationDelay'=>10, // not related to this post--but cool! // // default delay is 200 ms // ), )); ?> <p class="note">Fields with <span class="required">*</span> are required.

<?php echo $form->errorSummary($model); ?> <div class="row"> <?php echo $form->labelEx($model,'subject'); ?> <?php echo $form->textField($model,'subject',array('size'=>60,'maxlength'=>80)); ?> <?php echo $form->error($model,'subject'); ?> </div> <div class="row"> <?php echo $form->labelEx($model,'matn'); ?> <?php echo $form->textField($model,'matn',array('size'=>60,'maxlength'=>255)); ?> <?php echo $form->error($model,'matn'); ?> </div> <div class="row"> <?php echo $form->labelEx($model,'group'); ?> <?php echo $form->textField($model,'group',array('size'=>20,'maxlength'=>20,'value'=>$test)); ?> <?php echo $form->error($model,'group'); ?> </div> <?php $userX=yii::app()->session['idX']; ?> <div class="row"> <?php // echo $form->labelEx($model,'user_id'); ?> <?php echo $form->textField($model,'user_id',array ('value'=>$userX,'type'=>"hidden")); ?> <?php // echo $form->error($model,'user_id'); ?> </div> <div class="row"> <?php echo $form->labelEx($model,'Privacy'); ?> <?php echo $form->dropDownList($model,'Privacy', array('1'=>'Public','2'=>'Only me')); ?> <?php echo $form->error($model,'Privacy'); ?> </div> <div class="row buttons"> <?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save', array('id' => 'text_form_submit') ); ?> </div> <?php $this->endWidget(); ?> </div><!-- form --> <script> $(document).ready(function() { $('#text_form_submit').click(function(ev) { ev.preventDefault(); $.ajax({ type: 'GET', dataType: 'JSON', url: '<?php echo Yii::app()->createUrl("text/ACTION_NAME"); ?>', success:function(data){ // if(data !== null) { // $('#Text_group').val(data); // $('#text-form').submit(); alert("not Error occured!!!."); } }, error: function() { alert("Error occured!!!."); }, }); return false; }); }); </script>

this is my textController
