How to pass variables in the 'action' attribute of a form?

Question

I am trying to pass a variable inside the action attribute as shown

<form method="POST" action="{{url('/posts/{$post->id}/comments')}}">

The URL after submitting the form is this;

http://localhost/Laravel/public/posts/%7B$post-%3Eid%7D/comments

• 3Eid represents '->'

while the value of $post->id is supposed to be 30 in my case.

Can you please tell me the way to pass the value of $post->id?

• Script47: Rather than passing it through the URL, I would pass it as a input type="hidden".
• Script47: In the future please use the relevant tags and make your title clear.

Answer 1

replace ' with ": <form method="POST" action='{{url("/posts/{$post->id}/comments")}}'>

Answer 2

Change ' too "

so this

<form method="POST" action="{{url('/posts/{$post->id}/comments')}}">

becomes

<form method="POST" action='{{url("/posts/{$post->id}/comments")}}'>

Only if you use the double quotes you can echo with {}
