FatFree 模板中的 PHP 代码
我正在尝试使用 FatFree 框架并尝试使用模板引擎。我使用以下代码渲染模板 -
echo Template::serve('template.php');
我面临的问题是，在 template.php 文件中，F3 标签被识别，但任何 PHP 代码都不起作用。例如，如果我在 template.php 文件中有以下代码 -
<?php
if (F3::get('var') == 'var1') {
?>
<span>var1 is present</span>
<?php
} else {
?>
<span>var1 not present</span>
<?php
}
?>
无论 var 的值如何，都会打印 var1 is present 和 var1 not present 。另外，php for 循环不起作用 - 所以基本上所有 php 代码都不起作用。
但是，如果我使用
I am trying to work with FatFree framework and trying to use the template engine. I render the template with the following code -
echo Template::serve('template.php');
The problem which I'm facing is that, inside the template.php file the F3 tags are recognised but any PHP code doesn't work. For instance, if I have the following code in the template.php file -
<?php
if (F3::get('var') == 'var1') {
?>
<span>var1 is present</span>
<?php
} else {
?>
<span>var1 not present</span>
<?php
}
?>
Here both var1 is present and var1 not present is printed irrespective of the value of var. Also, php for loops are not working - so basically all the php code is not working.
However, if I used <F3:check> to write the above PHP code, then everything works fine. Can we not use PHP code in templates. If this is the case, this is a serious limitation.

我已经找到了答案，尽管我不太喜欢它。
有两个不同的函数，
F3::render()和Template::serve()使用
F3::render()您可以评估PHP 表达式并使用F3::get()检索变量。根据该网站的说法：“在模板中嵌入 PHP 代码的唯一问题是需要有意识地努力遵守 MVC 原则”Template::serve()适用于仅模板化。这意味着它只是处理模板语言。所以基本上，是的，它很糟糕并且没有意义，您可以在
F3::render()中评估 PHP 代码，并且不能使用模板变量 ({{@var }}) -或者- 您可以使用Template::serve()并且您只能调用 PHP 函数，而不能真正评估 PHP 代码。I have found the answer, although I don't really like it.
There is two different functions,
F3::render()andTemplate::serve()With
F3::render()you can evaluate PHP expressions and use theF3::get()to retrieve variables. According to the website:"The only issue with embedding PHP code in your templates is the conscious effort needed to stick to MVC principles"The
Template::serve()is for templating only. Meaning its simply to process the templating language.So basically, and yes it sucks and doesn't make sense, you can evaluate PHP code in the
F3::render()and you can't use templating variables ({{@var}}) -OR- you can useTemplate::serve()and you are limited to only calling PHP functions, and not truly evaluating PHP code.它没有文档记录，但您可以将代码放在模板中的
{~ ~}内，当模板编译时，它将转换为（使用v3.6）。例如
{~ @color = 'red' ~}将变为It is undocumented but you can put code within
{~ ~}in a template and it will be converted to<?php ?>when the template is compiled (using v3.6).e.g.
{~ @color = 'red' ~}will become<?php $color = 'red' ?>也许尝试使用不同的模板引擎，这将允许您更轻松地定义块变量依赖项？
例如在 PHPTal http://phptal.org/manual/en/split/tal -condition.html 你可以这样做：
Maybe try to use different template engine which will allow you define easier the blocks variable dependency?
For example in PHPTal http://phptal.org/manual/en/split/tal-condition.html you can do it like that:
