How to call controller's update function - php

Question

I am trying to use controller's update function on my dashboard.blade.php page, but when I press on "Save" it switches to show.blade.php page instead of updating.
My dashboard.blade.php page:
#if(count($posts) > 0 )
<table class="table table-striped">
<tr>
<th>Title</th>
<th>Body</th>
<th>Employee Number</th>
<th>Edit</th>
<th>Save</th>
</tr>
#foreach($posts as $post)
<tr>
<td>{{$post->title}}</td>
<td><input type='text' name='body'class='form-control' value='{{$post->body}}'></td>
<td>{{$post->employee_no}}</td>
<td><a href="{{ action("PostsController#update", $post->id) }}" >Save</a></td>
<td>Edit</td>
</tr>
#endforeach
</table>
#else
<p>You Have No Posts</p>
#endif
My update function on PostsController.php page:
public function update(Request $request, $id)
{
$this->validate($request,[
//'title' => 'required',
'body' => 'required'
]);
//Update Post
$post = Post::find($id);
//$post->title = $request->input('title');
$post->body = $request->input('body');
$post->save();
return redirect('/posts')->with('success','Post Updated');
}
I read that "action" will go to the first route that matches the pattern, but I do not know how to solve this problem.
My web.php page:
Route::get('/', 'PagesController#index');
Route::get('/about', 'PagesController#about');
Route::get('/services', 'PagesController#services');
Route::resource('posts','PostsController');
Auth::routes();
Route::get('/dashboard', 'DashboardController#index');
How can I call the update function correctly from dashboard.blade.php page?

Answer 1

To update data you have to use form with put method.
and route will be like this,
Route::put('dashboard/update/{id}',[
'uses' => 'DashboardController#update',
'as' => 'dashboard.update'
]);
For more Laravel Routing
Hope it helps :)

Answer 2

You can solve this by using form submit with hidden PUT method.
<form action="{{ url('customers') }}/{{$data['customer']->id}}" method="POST">
<input type="hidden" name="_method" value="PUT">
#csrf
</form>

How about having a simple form for each row in the table :
#if(count($posts) > 0 )
<table class="table table-striped">
<tr>
<th>Title</th>
<th>Body</th>
<th>Employee Number</th>
<th>Edit</th>
<th>Save</th>
</tr>
#foreach($posts as $post)
<tr>
<td>{{$post->title}}</td>
<td>{{$post->employee_no}}</td>
<td>
<!-- Form for each row -->
<form action="{{ route("posts.update", [ 'post' => $post->id ]) }}" method="POST">
#method('PUT')
#csrf
<input type='text' name='body'class='form-control' value='{{$post->body}}'></td>
<button type="submit">Save</button>
</form>
<!-- Form for each row -->
<td>Edit</td>
</tr>
#endforeach
</table>
#else
<p>You Have No Posts</p>
#endif
