How to know field is empty or not?

This code is in Cakephp and I want to check that name and mobile field are empty or not.

This is my ctp file code :-

<div class="form-group">
  <?= $this->Form->label('Name','Name',array('class' => 'col-sm-2 control-label')); ?>
  <div class="col-sm-4">
      <?= $this->Form->text('name', ['class' => 'form-control input-sm', 'style'=>'float:left', 'placeholder' => "Name"]); ?> 
  </div>
</div>
<div class="form-group">
<?= $this->Form->label('Mob No.','Mob No.',array('class' => 'col-sm-2 control-label')); ?>

     <?= $this->Form->text('mobile', ['class' => 'form-control input-sm', 'style'=>'float:left', 'placeholder' => "Mob No."]); ?>
 </div>
</div>

  if($this->request->is('post')){
      $result = null;
      $_Post['Name']= $name;
      $_Post['Mobile'] = $mobile;

Firstly, when you're using CakePHP, you should never use $_POST. It's better to follow the conventions and use $this->request->data['Modelname']['fieldname'] instead.

Secondly, you could specify your validation rules within your model. It will display the mentioned error messages on form submit.

Coming back to what you've done, you could try this below mentioned code:

      if($this->request->is('post')){
           $name   = $this->request->data['Modelname']['name'];
           $mobile = $this->request->data['Modelname']['mobile']; 
           // Specify your Model name for both. Eg: if your database table is users, your model name should be User.
           if(!empty($name) && !empty($mobile)){
               echo "Fields are not empty.";
           } else{
               echo  "Fields are empty.";
           }
       }
