好的，我的问题是这样的，我已经构建了一个服务构建块：
<?php
namespace Kpr\CentarZdravljaBundle\Extensions;
class Buildingblocks
{
protected $doctrine;
public function __construct($doctrine)
{
$this->doctrine = $doctrine;
}
public function articleHmostread($limit)
{
$em = $this->doctrine->getManager ();
$query = $em->createQuery(
'SELECT a2.title, a2.id, a2.body, a2.path, c.id as cid, c.name FROM KprCentarZdravljaBundle:Category c JOIN c.articles a2 WHERE c.parent !=3 GROUP BY a2.id ORDER BY a2.readCounter DESC'
);
$query->setMaxResults($limit);
$result = $query->getResult();
return $result;
}
public function testing()
{
$em = $this->doctrine->getManager ();
$query = $em->createQuery(
'SELECT a2 FROM KprCentarZdravljaBundle:Category c JOIN KprCentarZdravljaBundle:ARTICLE a2 WHERE c.id NOT IN (256) ORDER BY a2.readCounter DESC'
);
$result = $query->getResult();
return $result;
}
public function articleHnewest($limit)
{
$em = $this->doctrine->getManager ();
$query = $em->createQuery(
'SELECT a2.id, a2.title, a2.path, c.id as cid, c.name FROM KprCentarZdravljaBundle:Category c JOIN c.articles a2 WHERE c.parent !=3 GROUP BY a2.id ORDER BY a2.readCounter DESC'
);
$query->setMaxResults($limit);
$result = $query->getResult();
var_dump($result);
return $result;
}
public function articlesFromCat($id, $limit)
{
$em = $this->doctrine->getManager ();
$query = $em->createQuery(
'SELECT a2.title, a2.id, c.name FROM KprCentarZdravljaBundle:Category c JOIN c.articles a2 WHERE c.id = ?1 GROUP BY a2.id ORDER BY a2.published DESC'
)->setParameter(1, $id);
$query->setMaxResults($limit);
$result = $query->getResult();
return $result;
}
public function articleHfeatured($limit)
{
$em = $this->doctrine->getManager ();
$query = $em->createQuery(
'SELECT a, cat FROM KprCentarZdravljaBundle:Article a JOIN a.categories cat WHERE a.featured = ?1 GROUP BY cat.id ORDER BY a.published DESC'
)->setParameter(1, 1);
$query->setMaxResults($limit);
$result = $query->getResult();
return $result;
}
public function poiHomepage($limit)
{
$em = $this->doctrine->getManager ();
$query = $em->createQuery(
'SELECT p FROM KprCentarZdravljaBundle:Poi p ORDER BY p.published DESC'
);
$query->setMaxResults($limit);
$result = $query->getResult();
return $result;
}
}
然后我注册了一个全局树枝全局变量：
<?php
namespace Kpr\CentarZdravljaBundle\Twig;
use Kpr\CentarZdravljaBundle\Extensions\Buildingblocks;
use Kpr\CentarZdravljaBundle\Helper\Helper;
class MyRenderExtension extends \Twig_Extension
{
protected $bblocks;
function __construct(Buildingblocks $bblocks) {
$this->bblocks = $bblocks;
}
public function getGlobals() {
return array(
'bblocks' => $this->bblocks,
'globalimagepath' => 'uploads/documents/'
);
}
public function getFilters()
{
return array(
'pathauto' => new \Twig_Filter_Method($this, 'pathautoFilter'),
'groupname' => new \Twig_Filter_Method($this, 'groupnameFilter'),
'teaser' => new \Twig_Filter_Method($this, 'teaserFilter'),
'htmldecode' => new \Twig_Filter_Method($this, 'htmldecodeFilter', array(
'is_safe' => array('html')
)));
}
public function pathautoFilter($title)
{
$helper = new Helper();
return $helper->pathauto_cleanstring($title);
}
public function groupnameFilter($title)
{
$helper = new Helper();
return $helper->groupname($title);
}
public function htmldecodeFilter($string)
{
return html_entity_decode($string);
}
public function teaserFilter($text, $len = 120)
{
if(empty($text)) {
return "";
}
if(strlen($text)<$len) {
return $text;
}
return preg_match("/(.{1,$len})\s./ms", $text, $match)
? $match[1] ."..."
: substr($text, 0, $len)."...";
}
public function getName()
{
return 'myrender_extension';
}
}
?>
所以现在我可以使用任何模板中的 bblocks twig 变量，这是我的索引模板：
{% extends 'KprCentarZdravljaBundle:Main:framework.html.twig' %}
{% block content %}

但是有一个问题，当我从树枝上调用函数 articleHnewest
{% include "KprCentarZdravljaBundle:Parts:articleDefaultBlock.html.twig" with { articles: bblocks.articleHnewest(4), flag: 0 } only %}
我无法访问您可以在 BuildingsBlock 类 dql 中看到的键“c.name”和“c.id as cid”，因为在 twig 中解析时，我的 $result 变量以某种方式转换为对象列表而不是数组.
在将结果传递给 twig 之前，我尝试了 var_dump，我得到了一个数组，但是当我在 twig 中调试时，我得到了整个变量列表，并且我的浏览器由于大量数据而中断。
这是 BuldingBlocks->articleHnewest(4) 类中的 var_dump，您可以看到它是一个数组：
array(4) {
[0]=>
array(5) {
["id"]=>
int(7480)
["title"]=>
string(42) "Što trebate znati o glikemijskom indeksu?"
["path"]=>
string(18) "1365518301_407.jpg"
["cid"]=>
int(266)
["name"]=>
string(18) "Zdravlje općenito"
}
[1]=>
array(5) {
["id"]=>
int(7460)
["title"]=>
string(43) "Najbolje i najgore namirnice za alergičare"
["path"]=>
string(18) "1367243414_727.jpg"
["cid"]=>
int(286)
["name"]=>
string(8) "Alergije"
}
[2]=>
array(5) {
["id"]=>
int(7467)
["title"]=>
string(22) "Zašto volimo đumbir?"
["path"]=>
string(18) "1366634351_784.jpg"
["cid"]=>
int(267)
["name"]=>
string(15) "Biljni lijekovi"
}
[3]=>
array(5) {
["id"]=>
int(7459)
["title"]=>
string(25) "Najzdravija pića svijeta"
["path"]=>
string(18) "1367309468_956.jpg"
["cid"]=>
int(274)
["name"]=>
string(15) "Muško zdravlje"
}
}
添加 24.09.2013：
好的，我刚刚发现问题出在 index.html.twig 模板中的这部分代码中：
{% 仅包含“KprCentarZdravljaBundle:Parts:articleDefaultBlock.html.twig” 和 {articles:bblocks.articleHnewest(4), flag: 0 } %}
如果我直接在 index.html.twig 中从模板 articleDefaultBlock.html.twig 传输代码，一切正常。由于某种原因，包括模板中的模板会转换文章对象的结果列表，而不是带有我想要的记录数据的数组。
