Using $this when not in object context in

[Frodox]

I try to use phileTwigFilters , limit_words filter, but it returns an error:

Fatal error: Using $this when not in object context in   

/.../phile/plugins/phileTwigFilters/plugin.php on line 25

line 25: return trim(substr($string, 0, $pos[$this->settings['limit']])) . '...';

---

Actually, it there any way to modify meta-data of page depend on parsed content?
I didn't find any appropriate event, and the twig filter does not want to work too :D

I want to port my Pico Custom Post Preview Plugin...

Also, there is an event: template_engine_registered, but there are no lines in the docs about this :(

[james2doyle]

Hey there. I just checked the plugin. I didn't get the same error.

You are right about the template_engine_registered event. I can add the event to the docs.

Did you use limit_words filter, and set {{ page.content|limit_words }} exactly?

It's strange...

Do you have any sugestions?

[james2doyle]

Yeah. Here is my snippet I tested.

{% for page in pages %}
  <article>
    <h3>{{ page.title }}</h3>
    <p>{{ page.content|striptags|limit_words }}</p>
  </article>
{% endfor %}

I tried it without the striptags as well. Still no errors. What version of PHP are you on?

Offtopic

I also noticed in error.log, that [error] the key date for sorting is deprecated use meta:date or any other meta tag

Using the meta:date resolve an error, but it's default line in config..
$config['pages_order_by'] = 'title'; // Order pages by "title" (alpha) or "date"

PHP 5.3.20

[Frodox]

Oh, I think, it is a sort of anonymous function
and

Changelog
5.4.0 $this can be used in anonymous functions.

Am I right?

[james2doyle]

I also noticed in error.log...

Yeah that needs to be added to the documentation too. We would also need to change all the default .md files. Something for the backlog.

5.4.0 $this can be used in anonymous functions.

Thats a possibility. Can you give it a test and see?

[Frodox]

Can you give it a test and see?

Sure. I will do it right now.

[Frodox]

Yup, on PHP 5.4.4 all works fine.

P.s. @james2doyle Thanks for great video 👍

[james2doyle]

Thanks. It seems like just that plugin needs it then. Strange.
