当我尝试在单页中打开第一篇文章时,它正在打开;当我试图在单页中打开第二篇文章时,它显示“正在尝试获取非对象的属性'title'”
这是代码
FrontendController
public function singlePost($slug)
{
$post= Post::where('slug', $slug)->first();
return view('single')->with('post', $post)
->with('title', $post->title)
->with('settings', Setting::first())
->with('categories', Category::take(4)->get());
}
single.blade.php
在同一页面上使用相同的前端控制器 @extends('layouts.frontend')
@section('content')
<div id="product-post">
<div class="container">
<div class="row">
<div class="col-md-12">

在获取确切的列值之前,必须检查该值是否来自表。在这种情况下,如果表返回空结果,则可以将其重定向到404页。
请参考下面的代码:
public function singlePost($slug)
{
$post= Post::where('slug', $slug)->first();
if($post) {
return view('single')->with('post', $post)
->with('title', $post->title)
->with('settings', Setting::first())
->with('categories', Category::take(4)->get());
} else {
// You can redirect to 404 page
}
}
