我可以将我的 php 代码传递给木材的树枝代码吗 [英] can i pass my php code to twig code of timber

问题描述

我想知道我是否可以将任何类型的PHP代码转换为twig，我想知道的是，例如我是否可以通过代码.

I would like to know if I can convert any types of PHP code to twig, what I want to know is, for example, whether I can pass the code.

<?php
if (ICL_LANGUAGE_CODE == 'in'):?

到

{{ lang.en }}

有没有办法添加任何PHP代码并将其变成树枝并识别它?

Is there a way to add any PHP code and turn it into a twig and recognize it?

我使用 WordPress 的 Timber 模板.

I use the Timber template for WordPress.

推荐答案

有一种传递函数的好方法(更准确地说，是将函数注册到 Twig).

There is a good way to pass your functions (more correctly, register the function to Twig).

过滤器钩子timber/twig中有一个类可以帮助我们将函数传递给Twig.它调用 Timber\Twig_Function.

There is a class in filter hook timber/twig could help us pass functions to Twig. It calls Timber\Twig_Function.

new Timber\Twig_Function(
    'function_name_that_will_be_called_in_Twig',
    'function_name_in_php'
);

// OR
new Timber\Twig_Function(
    'function_name_that_will_be_called_in_Twig',
    function( $input ) {
        // anonymous function is ok too.
    }
);

functions.php

add_filter( 'timber/twig', 'add_to_twig' );

function hello_in_php( $name = 'world' ) {
    $hello = 'Hello ';
    $hello .= $name;

    return $hello;
}

function add_to_twig( $twig ) {
    $func = new Timber\Twig_Function('hello', 'hello_in_php');
    $filter = new Timber\Twig_Function('introduce', function( $name ) {
        return "I'm ${name}!";
    });

    $twig->addFunction($func); //Registering a pre-defined function
    $twig->addFunction($filter); //Registering a filter function

    return $twig;
}

index.twig:

<p id='a'>{{ hello() }}</p>
<p id='b'>{{ hello('who?') }}</p>
<p id='c'>{{ "Batman"|introduce }}</p>

结果是:

<p id='a'>Hello World</p>
<p id='b'>Hello who?</p>
<p id='c'>I'm Batman!</p>
