Thank you so much carlos,
it seems i have change the 3 errors that you mention, but i dont know
why i have still the error that the submit button doesn`t do nothing,
the code that i change in the files are this way:
- app/views/posts/view.ctp
<?php echo $ajax->form('/comments/
add','post',array('update'=>'comments','url'=>'/comments/add'));?>
<?php echo $form->input('Comment.name');?>
<?php echo $form->input('Comment.content');?>
<?php echo $form-
>input('Comment.post_id',array('type'=>'hidden','value'=>$post['Post']
['id']));?>
<?php echo $form->end('Add Comment');?>
- app/views/layouts/default.ctp
<head>
<title>My Cake Blog Application</title>
<?php echo $html->css('cake.generic'); ?>
<?php echo $javascript->link(array('prototype')); ?>
</head>
- app/controllers/comments_controller.php
function add() {
if (!empty($this->data)) {
$this->Comment->create();
if ($this->Comment->save($this->data)) {
$comments = $this->Comment-
>find('all',array('conditions'=>array('post_id'=>$this->data['Comment']
['post_id']),'recursive'=>-1));
$this->set(compact('comments'));
$this->render('add_success','ajax');
} else {
$this->render('add_failure','ajax');
}
}
}
The form html source code is this way
<form id="form123915682" onsubmit="event.returnValue = false; return
false;" method="post" action="/Blog/comments/add"><fieldset
style="display:none;"><input type="hidden" name="_method"
value="POST" /></fieldset><script type="text/javascript">
//<![CDATA[
Event.observe('form123915682', 'submit', function(event) { new
Ajax.Updater('comments','/Blog/comments/add', {asynchronous:true,
evalScripts:true, parameters:Form.serialize('form123915682'),
requestHeaders:['X-Update', 'comments']}) }, false);
//]]>
</script><div class="input text"><label for="CommentName">Name</
label><input name="data[Comment][name]" type="text" maxlength="100"
value="" id="CommentName" /></div><div class="input textarea"><label
for="CommentContent">Content</label><textarea name="data[Comment]
[content]" cols="30" rows="6" id="CommentContent" ></textarea></
div><input type="hidden" name="data[Comment][post_id]" value="1"
id="CommentPostId" /><div class="submit"><input type="submit"
value="Add Comment" /></div></form>
- And in the mozilla firebug i get these errors:
- syntax error
var $name = 'Js';\n
- Event.observe is not a function
Event.observe('form1428557839', 'submit'...rs:['X-Update',
'comments']}) }, false);
I dont know where else could the error be, thank you so much for your
help.
