title: CakePHP isn't saving long text
body: <p>I'm having one big trouble. I have a controller method that receives POST requests formatted in JSON.</p>
  
  <p>When I save JSON data, one field that is long text in MySQL isn't saving. But if I write short text, like "Hello World" it saves on DB. I don't know what is wrong here.</p>
  
  <p>This is my Javascript code: </p>
  
  <pre><code>                $http({
                      url: 'http://customblahblahblah',
                      method: 'POST',
                      data:   "user_id="+ user_id +
                      "&amp;token="+ token +
                      "&amp;object="+angular.toJson(myobject),....
  </code></pre>
  
  <p>This is my php code:</p>
  
  <pre><code>public function save(){
      if($this-&gt;request-&gt;is('post')){
          if($this-&gt;checkUser($this-&gt;request-&gt;data['user_id'], $this-&gt;request-&gt;data['token'])){
              $myObject = json_decode($this-&gt;request-&gt;data['object'], true);
              if($this-&gt;MyObject-&gt;save($myObject)){
                  .....
              }
       ....
             }
           }
        }    
  </code></pre>
  
  <p>What is wrong here?</p>
  
  <p>Because if in the property is set a text like "Hello World" it remains saved, but If I sent long text, like an newspaper article it seems to save (because doesn't throw an exception, and Model->save() is returning true) but the data isn't saved.</p>
