How to load a template from full path in the template engine TWIG
I'm wondering how to load a template from it's full path (like FILE constant give).
Actually you have to set a "root" path for template like this :
require_once '/path/to/lib/Twig/Autoloader.php';
Twig_Autoloader::register();
$loader = new Twig_Loader_Filesystem('/path/to/templates');
$twig = new Twig_Environment($loader, array(
'cache' => '/path/to/compilation_cache',
));
And then :
$templ开发者_StackOverflowate = $twig->loadTemplate('index.html');
echo $template->render(array('the' => 'variables', 'go' => 'here'));
I want to call the loadTemplate method with a full path and not the just the name of the file.
How can i do ?
I don't want to create my own loader for such an thing..
Thanks
Just do that:
$loader = new Twig_Loader_Filesystem('/');
So that ->loadTemplate() will load templates relatively to /
.
Or if you want to be able to load templates both with relative and absolute path:
$loader = new Twig_Loader_Filesystem(array('/', '/path/to/templates'));
Here is a loader that load an absolute (or not) path given :
<?php
class TwigLoaderAdapter implements Twig_LoaderInterface
{
protected $paths;
protected $cache;
public function __construct()
{
}
public function getSource($name)
{
return file_get_contents($this->findTemplate($name));
}
public function getCacheKey($name)
{
return $this->findTemplate($name);
}
public function isFresh($name, $time)
{
return filemtime($this->findTemplate($name)) < $time;
}
protected function findTemplate($path)
{
if(is_file($path)) {
if (isset($this->cache[$path])) {
return $this->cache[$path];
}
else {
return $this->cache[$path] = $path;
}
}
else {
throw new Twig_Error_Loader(sprintf('Unable to find template "%s".', $path));
}
}
}
?>
Extend the loader better than modify the library:
<?php
/**
* Twig_Loader_File
*/
class Twig_Loader_File extends Twig_Loader_Filesystem
{
protected function findTemplate($name)
{
if(isset($this->cache[$name])) {
return $this->cache[$name];
}
if(is_file($name)) {
$this->cache[$name] = $name;
return $name;
}
return parent::findTemplate($name);
}
}
This works for me (Twig 1.x):
final class UtilTwig
{
/**
* @param string $pathAbsTwig
* @param array $vars
* @return string
* @throws \Twig\Error\LoaderError
* @throws \Twig\Error\RuntimeError
* @throws \Twig\Error\SyntaxError
*/
public static function renderTemplate(string $pathAbsTwig, array $vars)
{
$loader = new Twig_Loader_Filesystem([''], '/');
$twig = new Twig_Environment($loader);
$template = $twig->loadTemplate($pathAbsTwig);
$mailBodyHtml = $template->render($vars);
return $mailBodyHtml;
}
}
Usage:
$htmlBody = UtilTwig::renderTemplate('/absolute/path/to/template.html.twig', [
'some' => 'var',
'foo' => 'bar'
]);
In Symfony's (version 5.4) config add new core path to folder with your templates.
twig:
default_path: '%kernel.project_dir%/templates'
paths:
'%kernel.project_dir%/src/Service/SendEmail/EmailTpl': EmailTpl
Now you can render template.
In controller:
$this->render('@EmailTpl/bobo_reg.html.twig')
In any other place:
$content = $this->container->get('twig')->render('@EmailTpl/bobo_reg.html.twig');
