php - yii text field validtaion with ckeditor -

i have text field in have used ckeditor

<div class="row">     <?php echo $form->labelex($model,'text'); ?>     <?php echo $form->textarea($model, 'text', array('id'=>'editor1')); ?>     <?php echo $form->error($model,'text'); ?> </div>  <script type="text/javascript">     ckeditor.replace( 'editor1' ); </script> 

rules in model is

public function rules() {  return array(     array('text', 'required'),   array('text', 'validatewordlength') ); }   public function validatewordlength($attribute,$params) {     $total_words= str_word_count($this->text);     if($total_words>4000)     {        $this->adderror('text', 'your description length exceeded');     }     if($total_words<5)     {        $this->adderror('text', 'your description length small');     }  } 

this works fine

1) when leave field blnk required text error.

2) when write words less them 5 or more 4000 desired error

but when insert blank space not getting error , form submitted.

please appreciated!!

you can use regex remove multipe whitespaces in function

public function validatewordlength($attribute,$params) {     $this->text = preg_replace('/\s+/', ' ',$this->text);      $total_words= str_word_count($this->text);     if($total_words>4000)     {        $this->adderror('text', 'your description length exceeded');     }     if($total_words<5)     {        $this->adderror('text', 'your description length small');     }  }
