I am trying to update a DOM element with HTML generated from a symfony

  • 0

I am trying to update a DOM element with HTML generated from a symfony partial. I am using Symfony 1.3.8

Here is the (simplified) Symfony/PHP part:

public function executeFoobar(sfWebRequest $request)
{
   $results = $this->renderPartial('foo/bar');
   $this->getResponse()->setContentType('text/json');
   return $this->renderText(json_encode(array('data' => $results)));
}

Here is the (simplified) HTML/jQuery part

<html>
<head><script type="text/javascript" src="/js/jquery.js"></script>
<body>
<a id='foo' href='#'>Click foo</a>
<div id="sink"></div>
</body>
<script type="text/javascript">
$(document).ready(function(){
   $('#foo).click(function(){
       $.ajax( {
         type: 'POST',
         url: '/ajax-example'
         dataType: 'json',
         success: function(result){ $('#sink).val(result.data); }
         error: function(xhr, ajaxOptions, thrownError){ alert('Error: ' + thrownError); }
       });
   });
});
</script>
</html>

When I submit the AJAX post, the html is generated server side, but I then get the error on the browser with the following message:

 Error: Invalid JSON: <table>
       <tr><!-- Rest of generated HTML follows .... -->
        {"data": GENERATED_HTML }

Where GENERATED_HTML is the HTML generated at the server side – i.e.:

 <table>
       <tr><!-- Rest of generated HTML follows .... -->

So it seems the HTML is being included twice or something. Has anyone come accross this before – what am I doing wrong?

    renderPartial echos the text to screen. You need to use get_partial from the PartialHelper

    public function executeFoobar(sfWebRequest $request)
{
     $this->getContext()->getConfiguration()->loadHelpers('Partial');

     $results = get_partial('foo/bar');
     $this->getResponse()->setContentType('text/json');
     return $this->renderText(json_encode(array('data' => $results)));
}

    It’s either loadHelpers of loadHelper I can’t remember off the top my head, sorry.
