  1. POProblem with Ajax Helper in Cake PHP
    text
    copied!<p>I am trying to implement the Ajax feature in the comments section of my blog. I have downloaded prototype-1.6.0.3.js and have placed it in the js folder inside webroot. I have made the following changes in the layout file(default.ctp)</p> <pre><code>$javascript-&gt;link(array('prototype')); </code></pre> <p>Also, following code has been added to controllers</p> <pre><code>var $helpers = array('Html', 'Form', 'Ajax','Javascript'); </code></pre> <p>This is my code in the posts_controller.php file</p> <pre><code>function view($id = null) { if (!$id) { $this-&gt;Session-&gt;setFlash(__('Invalid Post.', true)); $this-&gt;redirect(array('action'=&gt;'index')); } $post = $this-&gt;Post-&gt;read(null,$id); $comments = $this-&gt;Post-&gt;Comment-&gt;find('all', array('conditions'=&gt;array('Post.id'=&gt;$id))); $this-&gt;set(compact('post','comments')); } </code></pre> <p>My code in view.ctp file</p> <pre><code>&lt;h2&gt;Comments&lt;/h2&gt; &lt;div id="comments"&gt; &lt;?php foreach($comments as $comment): ?&gt; &lt;div class="comment"&gt; &lt;p&gt;&lt;b&gt;&lt;?php echo $comment['Comment']['name']; ?&gt;&lt;/b&gt;&lt;/p&gt; &lt;p&gt;&lt;?php echo $comment['Comment']['content']; ?&gt;&lt;/p&gt; &lt;/div&gt; &lt;?php endforeach; ?&gt; &lt;?php echo $ajax-&gt;form('/comments/add','post',array('update'=&gt;'comments'));?&gt; &lt;?php echo $form-&gt;input('Comment.name');?&gt; &lt;?php echo $form-&gt;input('Comment.content');?&gt; &lt;?php echo $form-&gt;input('Comment.post_id',array('type'=&gt;'hidden','value'=&gt;$post['Post']['id']));?&gt; &lt;?php echo $form-&gt;end('Add Comment');?&gt; &lt;/div&gt; </code></pre> <p>I have added the following function in the comments_controller.php</p> <pre><code>function add() { if (!empty($this-&gt;data)) { $this-&gt;Comment-&gt;create(); if ($this-&gt;Comment-&gt;save($this-&gt;data)) { $comments = $this-&gt;Comment-&gt;find('all',array('conditions'=&gt;array('post_id'=&gt;$this-&gt;data['Comment']['post_id']),'recursive'=&gt;-1); $this-&gt;set(compact('comments')); $this-&gt;render('add_success','ajax'); } else { $this-&gt;render('add_failure','ajax'); } } } </code></pre> <p>And following is the code in the add_success.ctp file</p> <pre><code>&lt;?php foreach($comments as $comment): ?&gt; &lt;div class="comment"&gt; &lt;p&gt;&lt;b&gt;&lt;?php echo $comment['Comment']['name'];?&gt;&lt;/b&gt;&lt;/p&gt; &lt;p&gt;&lt;?php echo $comment['Comment']['content'];?&gt;&lt;/p&gt; &lt;/div&gt; &lt;?php endforeach;?&gt; </code></pre> <p>Now the problem is that I am not able to add comments. Nothing happens when I click on the add comments button. I have manually added comments in the databse and that works. But I am having problems when I am trying the Ajax Helper.</p> <p>Where is the problem??And guys, sorry for such a long question.[:(]</p>
