奇怪的Symfony2学说结果行为

好的我的问题是，我已经建立了一个服务构建块：

<?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

时 
{% include "KprCentarZdravljaBundle:Parts:articleDefaultBlock.html.twig" with { articles: bblocks.articleHnewest(4), flag: 0 } only %}

我无法访问密钥＆＃34; c.name＆＃34;和＆＃34; c.id作为cid＆＃34;你可以看到我进入了BuildingsBlock类的dql，因为不知何故我的$ result变量在twig中被解析时被转换为对象列表而不是数组。

我在twig中传递结果之前尝试了var_dump，我得到了一个数组，但是当我在twig中调试时，由于压倒性的数据，我得到了整个变量列表和浏览器中断。

这是在BuldingBlocks-＆gt; articleHnewest（4）类中的var_dump，它是一个数组，你可以看到：

    array(4) {
      [0]=&gt;
      array(5) {
        ["id"]=&gt;
        int(7480)
        ["title"]=&gt;
        string(42) "Što trebate znati o glikemijskom indeksu?"
        ["path"]=&gt;
        string(18) "1365518301_407.jpg"
        ["cid"]=&gt;
        int(266)
        ["name"]=&gt;
        string(18) "Zdravlje općenito"
      }
      [1]=&gt;
      array(5) {
        ["id"]=&gt;
        int(7460)
        ["title"]=&gt;
        string(43) "Najbolje i najgore namirnice za alergičare"
        ["path"]=&gt;
        string(18) "1367243414_727.jpg"
        ["cid"]=&gt;
        int(286)
        ["name"]=&gt;
        string(8) "Alergije"
      }
      [2]=&gt;
      array(5) {
        ["id"]=&gt;
        int(7467)
        ["title"]=&gt;
        string(22) "Zašto volimo đumbir?"
        ["path"]=&gt;
        string(18) "1366634351_784.jpg"
        ["cid"]=&gt;
        int(267)
        ["name"]=&gt;
        string(15) "Biljni lijekovi"
      }
      [3]=&gt;
      array(5) {
        ["id"]=&gt;
        int(7459)
        ["title"]=&gt;
        string(25) "Najzdravija pića svijeta"
        ["path"]=&gt;
        string(18) "1367309468_956.jpg"
        ["cid"]=&gt;
        int(274)
        ["name"]=&gt;
        string(15) "Muško zdravlje"
      }
    }

于2013年9月24日添加：

好的，我刚刚发现问题出在index.html.twig模板中的这部分代码中：

  

{％include＆＃34; KprCentarZdravljaBundle：Parts：articleDefaultBlock.html.twig＆＃34; {articles：bblocks.articleHnewest（4），flag：0} only％}

如果我直接在index.html.twig中从模板articleDefaultBlock.html.twig传输代码，一切正常。由于某些原因，包括模板内的模板转换了文章对象的结果列表，而不是包含我想要的记录数据的数组。

1 个答案:

答案 0 :(得分：0)

好的，我只想知道导致这种行为的原因，当我将多个变量传递给include twig标签时，bblocks.articleHnewest（4）结果被转换为对象列表，所以当我删除第二个变量flag = 0时结果保持原始状态。为什么会发生这种情况我不知道，如果有人知道请分享。

解决这个问题的方法是分别在twig中设置变量，然后将这些变量全部传递给包含这样的包含：

  

{％set newestArt = {articles：bblocks.articleHnewest（4），flag：0}％}

然后

  

{％include“KprCentarZdravljaBundle：Parts：articleDefaultBlock.html.twig”with {articles：bblocks.articleHnewest（4），flag：1}

你把

  

{％include“KprCentarZdravljaBundle：Parts：articleDefaultBlock.html.twig”with newestArt％}

感谢。
