Ajax query - area handler

Permalink 1 user found helpful
Hi, I'm having problems while creating an ajax form inside a block.

If I use the code from Andrew:
if ($_REQUEST['ajax'] == true) {
         $b = $this->getBlockObject();
         $bv = new BlockView();
         $bv->render($b);

the code generated does not know the area of the block, so i can't use 
$this->action('vote');

as arHandle becomes null.

Is there any way to avoid this or to know the current BlockView Area inside the Block Controller?

Thanks in advance.

Can you explain a little more about the context you're using this in?

I'm a little unclear on why you need to do all of that stuff with the BlockView -- if you're just displaying a form that uses ajax to submit, $this->action() should work fine. But obviously you're trying to do something else otherwise you wouldn't be having a problem :)

Yes, the problem is that the form has to appear again after submit, so that the user can submit data again.

My (ugly) solution is:

in view.php
if (isset($_POST['arHandle']))
        $arHandle=htmlentities($_POST['arHandle'],ENT_QUOTES);//or any other sanitize
    else
        $arHandle=$this->block->a->arHandle;

in form tag
<form action="<?php echo $this->action('theaction'); ?>&arHandle=<?php echo $arHandle;?>" method="post">

inside form
<input type="hidden" name="arHandle" value="<?php echo $arHandle;?>" />

and in view.js, of course,
arHandle:jQuery('form input[name=arHandle]').val()

Got it. I think your solution is probably the best one -- not ugly at all!

One thing I've come to appreciate about building modules for Concrete5 (and other frameworks) is that it's not such a big deal if your code isn't perfectly architected, because you're only working with a small and self-contained portion of the system. Even if something is a little messy, it's only going to be in a couple of files and you will know how to find them.

Best of luck.
