//这是view.blade.php文件。它显示上述错误可以任何人请给出想法什么是错的。路线。 php文件和博客controller.php如下。，也许问题出在控制器或路径文件中，我不知道。

/// view.blade.php

Answer 1

您的参数应该是这样的

<form action="{{ URL::route('createComment', array('id'=>$post->id))}}" method="POST">

注意： laravel刀片模板{{}}相当于echo所以现在您的传递参数在外面。所以它试图回应阵列。所以这里echo不能回显数组变量。这就是为什么它会给出这个错误。

数组到字符串转换

ErrorException（E_ERROR）HELP数组转换为字符串（视图：C：\ xampp \ htdocs \ blog50 \ app \ views \ blog \ view.blade.php）
