Question

我遵循knpsnappybundle的教程在symfony3中使用pdf，但问题是我需要将一个值数组传递给pdf页面，这样我就能获得像原始页面一样的完整页面

这是控制器：

public function pdfAction(){
    $html = $this->renderView('@Recommendation/Recommendation/payment-successful.html.twig');

    $filename = sprintf('test.pdf', date('Y-m-d'));

    return new Response(
        $this->get('knp_snappy.pdf')->getOutputFromHtml($html),
        200,
        [
            'Content-Type'        => 'application/pdf',
            'Content-Disposition' => sprintf('inline; filename="%s"', $filename),

        ]
    );

}

这是普通页面的图片，带有PRINT按钮代码：

<a href="{{ path('payment_pdf') }}"><button>PRINT</button></a>

和路线：

payment_pdf:
path:     /payment_pdf
defaults: { _controller: "RecommendationBundle:Recommendation:pdf"}

我原始页面的图片： https://i.stack.imgur.com/3MBEt.png

现在生成的pdf图片： https://i.stack.imgur.com/rqs2x.png

你看到桌子是空的！

我的路线：

recommendation_bookid：路径：/ book_detail / {id} 默认值：{_ control：“RecommendationBundle：Recommendation：afficheparid”} recommendation_book：路径：/ book_detail 默认值：{_ control：“RecommendationBundle：Recommendation：affiche”} recommendation_new：路径：/ book_detail / {id} / new 默认值：{_ control：“RecommendationBundle：Recommendation：Ajout”} recommendation_delete：路径：/ book_detail / {id_l} / {id_r} / delete 默认值：{_ control：“RecommendationBundle：Recommendation：Delete”} recommendation_edit：路径：/ book_detail / {id_l} / {id_r} /编辑默认值：{_ control：“RecommendationBundle：Recommendation：Update”} recommendation_find：路径：/ book_detail / {id_l} / {id_r} / find 默认值：{_ control：“RecommendationBundle：Recommendation：Find”} recommendation_cart：路径：/ book_detail / {id} / cart 默认值：{_ control：“RecommendationBundle：Recommendation：cart”} recommendation_empty：路径：/ emptycart 默认值：{_ control：“RecommendationBundle：Recommendation：emptycart”} recommendation_cart_remove：路径：/ remove_book / {id} 默认值：{_ control：“RecommendationBundle：Recommendation：removebookcart”} recommendation_cart_show：路径：/ remove_book 默认值：{_ control：“RecommendationBundle：Recommendation：show”} payment_ok：路径：/ payment_success 默认值：{_ control：“RecommendationBundle：Recommendation：ok”}

payment_pdf：路径：/ payment_pdf 默认值：{_ control：“RecommendationBundle：Recommendation：pdf”}

Answer 1

好的，我认为您需要做的就是从控制器传入livres变量。我不知道它叫什么，也许$livres？

所以这样：

public function pdfAction(){
    $html = $this->renderView('@Recommendation/Recommendation/payment-successful.html.twig', array(
        'livres'  => $livres
    ));

    $filename = sprintf('test.pdf', date('Y-m-d'));

    return new Response(
        $this->get('knp_snappy.pdf')->getOutputFromHtml($html),
        200,
        [
            'Content-Type'        => 'application/pdf',
            'Content-Disposition' => sprintf('inline; filename="%s"', $filename),
        ]
    );
}

我认为应该这样做。

Answer 2

阅读本文： https://symfony.com/doc/current/components/http_foundation/sessions.html

这就是在Symfony中完成会话的方式。你需要改变一些事情......

Answer 3

<强> FIXED：

我不需要将数组作为参数传递！我只是声明了一个这样的变量：$ cart = $ _SESSION ['cart']（$ _SESSION ['cart']是我用来存储我的变量的数组）在我的pdfController中并直接传递它： $ html = $ this-＆gt; renderView（'@ Recommendation / Recommendation / payment-pdf.html.twig'，array（ 'livres'=＆gt; $车））;

我正在使用SESSION数组，因此它被视为全局变量：）
