Question

是否可以将数组作为参数发送给函数？在网上搜索过，但对我没有太大帮助。这就是我所拥有的：

在我的树枝上，我有：

<a id="exporttocsv" href="{{ path('dashboard.index', {'data': tableresults|json_encode}) }}" class="btn btn-default">Export to CSV</a>

在我的控制器中：

public function exporttocsvAction(Application $app, Request $request, $data)
{
    header("Content-Type: text/csv");
    header("Content-Disposition: attachment; filename=test.csv");
    header("Pragma: no-cache");
    header("Expires: 0");

    $output = fopen("php://output", "w");

    foreach ($data as $row)
    {
        fputcsv($output, $row, ',');
    }

    fclose($output);
    exit();
}

但是当我点击我的按钮时，我的链接会变成这样的东西，只是刷新：

是否可以发送数组？或者我应该使用ajax调用并发送数据吗？

Answer 1

要在GET请求中传递数组，请检查此答案how to pass an array in GET in PHP?。

您也可以在POST请求中执行此操作，例如使用此处所述的表单Passing arrays from HTML form to PHP。

但在你的情况下，似乎最好的方法是使用ajax + json传递它然后在服务器端解码。请检查以下答案How to pass an array using PHP & Ajax to Javascript?：）

将数组作为参数+ twig发送
