Cakephp important facts you must know – Part 3

  • You load a plugin model like this: $this->loadModel(“Forum.Topic”)
  • You output requestAction result using $this->requestAction(array(‘controller’ => ‘articles’, ‘action’ => ‘featured’), array(‘return’)); // see array(‘return’)
  • In controller, doing $this->set(‘first_name’) set variable $firstName for the view.
  • You can use HTML in  $html->link like this:
    echo $html->link(“Hello <i>Dear jan<i>”, array(‘controller’ => ‘categories’, ‘action’ => ‘view’, $topic[‘ForumCategory’][‘id’]), null, false, false); //Note 5th argument “escape title” = false, check libs/view/helpers/html.php for more details
  • Use $text->truncate to truncate content with HTML, it does take care of HTML well provided you pass true in 5th argument. Example call: $text->truncate($text, $length = 100, $ending = ‘…’, $exact = true, $considerHtml = false)
  • If the targetted form action isn’t in the current controller, you can specify a URL for the form action using the ‘url’ key of the $options array. The supplied URL can be relative to your CakePHP application, or can point to an external domain. For example,<?php echo $form->create(null, array(‘url’ => ‘/recipes/add’)); ?>
    // or
    <?php echo $form->create(null, array(‘url’ => array(‘controller’ => ‘recipes’, ‘action’ => ‘add’))); ?>
  • You can print model errors dump in a controller like this:if(!$this->Model->save($this->data))    {
    pr($this->Model->validationErrors);
    }
  • You can always run db queries like this:$this->Profile>query(“delete from `users` where id=”.$this->Profile->id);

    //note the use of ‘Profile’ model. Any loaded model could be used to run a custom query on any other table of the current selected database.

  • Save single field value using saveField. For example:$this->User->id = $userId;
    $this->User->saveField(‘is_active’, “1”);
  • You can stop your controller action from rendering the view by using:
    $this->autoRender = false; //if can come handy particularily in case of ajax call where you dont want view to be rendered or no view at all.
  • You can use Configure::write(‘debug’, 0); within a controller action in case your debug derivative is set to greate than 0 in core.php file you dont want a particular action to show debug log at the bottom of page. This can come handy in case of ajax call.
