Laravel 5.8 Editing a Post results in 404 error - php

Question

I have added Datatables in my application and i wanted to make the ID of each entry to be a hyperlink to the edit page in order for a user to be able to edit their Post. But i am getting a 404 Not Found error
I tried updating my route file but i don't get the correct result and i cannot figure what i am doing wrong
My web php file has:
Route::get('edit','PostsController#edit');
The index for my posts is
<table class="display" id="postsTable">
<thead>
<tr>
<td>ID</td>
<th>Title</th>
<th>Slug</th>
<th>Subtitle</th>
<th>Content</th>
<th>Category</th>
</tr>
</thead>
<tbody>
#foreach($posts as $post)
<tr>
<td>{{$post->id}}</td>
<td>{{$post->title}}</td>
<td>{{$post->slug}}</td>
<td>{{$post->subtitle}}</td>
<td>{{$post->content}}</td>
<td>{{$post->category_id}}</td>
</tr>
#endforeach
</tbody>
And the PostsController edit function is:
public function edit($id)
{
$posts = Post::findOrFail($id);
return view('posts.edit',compact('posts'));
}
I tried searching online and playing a bit with my routes but i managed to make things worse rather than solving my issue. any help is much appreciated!

Answer 1

You can set Route name like below
Route::get('edit/{id}','PostsController#edit')->name('edit_post');
Then in HTML section use it like below
<tbody>
#foreach($posts as $post)
<tr>
<td>Edit Post</td>
<td>{{$post->title}}</td>
<td>{{$post->slug}}</td>
<td>{{$post->subtitle}}</td>
<td>{{$post->content}}</td>
<td>{{$post->category_id}}</td>
</tr>
#endforeach
</tbody>
You should add some validation on client side to be sure that you have data so you can add your code inside if condition like below
#if ($posts ?? count($posts) ?? false)
// Your code here
#endif

Answer 2

Are you sure there is a record in your database that matches the $id that came with the get method? If there is no matching record, findOrFail($id) returns 404 pages.

Answer 3

In your controller check, the posts are found or not
public function edit($id)
{
$posts = Post::findOrFail($id);
// check post are found or not
if(!isset($posts)){
# show your errors if data not found
}
return view('posts.edit',compact('posts'));
}
