[Tutorial] Convert to Twig Syntax

[Kuzia]

What about form tokens? {S_FORM_TOKEN} is still in use?

See the very first example in the first post.

Just in reply of this question, specifically. Also if it is something that doesn't really IMO belongs to this topic.

YES, it is. And the related PHP side of the medal, that's considered a security issue if missing, beware.

Twig: {{ S_FORM_TOKEN }}

Hello again,

I am trying to do something like this, but I cannot make it to work in Twig.

An interesting effect of this, is that now, in the Twig template syntax, you CAN use language keys with parameters! So you could write something like {{ lang('KEY', 3) }} or even nesting vars, if that is allowed {{ lang('KEY', {{ VALUE }}) }}

This works {{ lang('KEY', 3) }}, but what doesn't work is the nesting of variables as in {{ lang('KEY', {{ VALUE }}) }}, neither using them in set statements {% set newvar = {{ VALUE }} %}.

Any clues?

Thanks a lot.

Another question: how to perform simple arithmetics with template variables, like {{ TOTAL }} - {{ USED }} and use the resulting value?

No need for nesting:

• {{ lang('KEY', VALUE) }}
• {% set newvar = VALUE %}
• {{ TOTAL - USED }}
• {% set newval = TOTAL - USED %}

Thanks a lot kasimi!!!

How much faster does this make your site/take the load off your server?

[kasimi]

I haven't done any performance tests but I'd assume it's negligible for two reasons:

1. As phpBB doesn't differentiate between templates that use phpBB syntax and templates that use Twig syntax, the code that checks for phpBB syntax has to run on all template files, regardless of them using phpBB or Twig syntax.
2. Once converted, templates are cached. They are not converted for every request.

I'm updating my style @ the moment for phpBB 3.2.1 RC1
It's best to convert the whole style to Twig Syntrax then?

[kasimi]

It is recommended to not mix them both. Also have a look at the Twig Converter.

Converted all the extensions, styles & admin panel.
No problems so far.. Great ext!

Does phpBB recommend any particular file extension when converting to twig: .html, .twig, .html.twig?

BTW, it appears that template events are currently set to only work with .html.

[3Di]

.html as usual

Maybe I'm missing something?

Old code:

Code: Select all

var collapseImageIdAlt = '{LA_DIGESTS_COLLAPSE}';
var collapseImageIdTitle = '{LA_DIGESTS_COLLAPSE}';

Resulting HTML source code generated:

Code: Select all

var collapseImageIdAlt = 'Collapse';
var collapseImageIdTitle = 'Collapse';

New code:

Code: Select all

var collapseImageIdAlt = '{{ lang(DIGESTS_COLLAPSE)|addslashes }}';
var collapseImageIdTitle = '{{ lang(DIGESTS_COLLAPSE)|addslashes }}';

Resulting HTML source code generated:

Code: Select all

var collapseImageIdAlt = '';
var collapseImageIdTitle = '';
