[英]Symfony2/Twig: how to tell the custom twig tag to NOT escape the output
[英]Sending TWIG output to a zip in Symfony for Templating
我需要创建一个能够基于一组选项(包括菜单1,使用小页脚等)输出模板(根据需要包含所有js,css,img等文件的index.html的zip文件)的系统。
因此,我可以放入代码块,这样实际上就不会很难将所需的外观输出到浏览器,但是如果我想保存渲染的html会怎样(这意味着我们需要更改js等文件的位置)改成拉链?
有任何想法吗? 目前,我认为无论如何都需要使用PHP(控制器)进行处理,而TWIG可能并没有太大帮助,但这会使它变得更加复杂。
所以我解决了这个问题,这里是控制器,用于输出所需的压缩过的树枝:
<?php
namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
class DefaultController extends Controller
{
/**
* @Route("/{variableName}", name="homepage"})
*/
public function indexAction($variableName = "Default")
{
//do whatever you need to get the template correct
//send rendered TWIG to a variable
$renderedhtml = $this->render('default/index.html.twig', [
'variableName' => $variableName
])->getContent();
$zipName = "template.zip";
$main = $this->get('kernel')->getRootDir() . '/../web/workingdir/';
$vername = time(); //we use the exact time to get a unique dir name
//remove any projects older than a few minutes (5 in this case)
$dirHandle = opendir($main);
while($item = readdir($dirHandle)){
if(is_dir($main . $item) && $item != '.' && $item != '..') {
if ( ( ( $item + ( 60 * 5 ) ) < $vername ) ) {
system('/bin/rm -rf ' . escapeshellarg($main . $item));
}
}
}
//make the project dir and populate it with files (in this case just the template as index.html, you would want to copy all other files here though)
mkdir($main.$vername);
file_put_contents($main.$vername."/index.html", $renderedhtml);
//create the zip
$zip = new \ZipArchive();
$zip->open($zipName, \ZipArchive::CREATE);
$zip = $this->createZip($zip, $main.$vername);
$zip->close();
//get the zip ready to return
header('Content-Type', 'application/zip');
header('Content-disposition: attachment; filename="' . $zipName . '"');
header('Content-Length: ' . filesize($zipName));
readfile($zipName);
}
// Create a zip with zip object and root dir params (find and include sub-dirs with content)
private function createZip($zip, $source) {
$source = str_replace('\\', '/', realpath($source));
if (is_dir($source) === true) {
$files = new \RecursiveIteratorIterator(new \RecursiveDirectoryIterator($source), \RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file) {
$file = str_replace('\\', '/', $file);
if( in_array(substr($file, strrpos($file, '/')+1), array('.', '..')) )
continue;
$file = realpath($file);
if (is_dir($file) === true)
{
$zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
}
else if (is_file($file) === true)
{
$zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
}
}
}
return $zip;
}
}
一旦进入此阶段,您只需要将其他所有必需的文件添加到工作目录中即可,但是我认为可以在其他问题下完成,这是将网站转换为zip格式的html。
希望这对某人有帮助。
