Twig syntax error when enabling ESI in symfony 2.1.8

Question

Ive attempted to add an ESI render with {'standalone': true} to one of my twig templates and am getting the TWIG syntax error of:

Unexpected token "punctuation" of value "," ("end of statement block" expected) in AccommMiddleBundle:Home:layout.html.twig at line 155

here is the relevant twig template block:

150 <div class="container">
151     <h1>{{ blog_articles.0.title }}</h1>
152     <a href="{{blog_articles.0.guid}}">Moose</a>
153 </div>
154 
155 {% render url('accomm_middle_home_recent_articles', {fred: 1}), {'standalone': true} %}
156 
157 {% set charity_url = "http://www.accommodation.com/charity" %}

Removing the , {'standalone': true} gets the template to render fine.

Im using Symfony 2.1.8 with a clean vendors and there seems to be no differences with the standard edition dependencies. Any ideas on how to debug this ?

thanks for any help

Answer 1

In Symfony2.1, to adapt your render block to the correct notation, you need to

• put your arguments between single quote ' : in this case you would have'fred': 1
• Add the with{} statement even if it's empty:

Which gives you:

{% render url('accomm_middle_home_recent_articles', {'fred': 1})  with {}, {'standalone': true} %}

---

Note: It looks like the with{} statement is absolutely needed in Symfony2.1, from this security release. However, Symfony might have changed this recently and I don't think it is needed in Symfony2.2 anymore.

{# the with argument is needed but ignored #}

And an example they provide with it:

{% render url("path_to_controller_router", { 'param': 1 }) with {}, { 'standalone': true } %}
