Laravel: Cannot route to expected URL - php

Question

Here is my nav-bar:
<div class="col-md-2">
<ul class="list-group-item">
<li><i class="fa fa-fw fa-file</i> All Post
</li>
<li><i class="fa fa-fw fa-plus-circle"></i> Create New Post</li>
<li><i class="fa fa-fw fa-tasks"></i> Manage Posts</li>
</ul>
</div>
and here is my route.php
Route::group(['prefix' => 'posts'], function(){
Route::get('', 'PostController#index');
Route::get('create', 'PostController#create');
Route::post('confirm', 'PostController#confirmation');
Route::get('{postID}', 'PostController#show');
Route::get('posts/manage', 'PostController#manage');});
I expect when I click on the "Manage Posts" button, it will redirect me to function manage() in my PostController.
But when I click on it, it redirects to a view which belongs to storage/framework/views which is show() in my PostController.
I don't know why and how to make it to the right url.
Can somebody help me with this one please?
Thank you.

Answer 1

First of all, your link links to /posts/management, not /posts/manage. Second, you already have the prefix posts for this route-group, so the route posts/manage will be available under the url /posts/posts/manage.
You also want to move the manage route before your {postID} route, because {postID} will just catch anything, so the router has to first check the manage-route, and only if it doesn't match, the catch-all route.
And you should control what is accepted as a valid postID using Route Parameters: Regular Expression Constraints.
Route::get('{postID}', 'PostController#show')->where('id', '[0-9]+');
