問題描述

我是 Laravel 的新手，我很喜歡它.在處理社交媒體項目時，我收到此錯誤:htmlspecialchars() 期望參數 1 為字符串，給定對象(視圖:C:wamp64wwwhistoirevraie esourcesviewsuserprofile.blade.php)

I am new to laravel and I am enjoying it. While working on a social media project I got this error: htmlspecialchars() expects parameter 1 to be string, object given (View: C:wamp64wwwhistoirevraie esourcesviewsuserprofile.blade.php)

我在這個網站上檢查了一些問題，但我沒有找到解決我問題的問題.

I have checked some questions on this site but I have not found a question that solves my problem.

這是我的 profile.blade.php 的組成:

<ul class="profile-rows">
    <li>
        <span class="the-label">Last visit: </span>
        <span class="the-value mark green">{{ CarbonCarbon::createFromFormat('Y-m-d H:i:s', $user->lastVisit)->diffForHumans(CarbonCarbon::now())}}</span>
    </li>
    <li>
        <span class="the-label">Member since: </span>
        <span class="the-value mark light-gray">{{ $user->created_at->format('F Y') }}</span>
    </li>
    <li>
        <span class="the-label">Profile views: </span>
        <span class="the-value mark light-gray">5146</span>
    </li>
    <li>
        <span class="the-label">Living In: </span>
        <span class="the-value">{{ $user->town }}</span>
    </li>
    <li>
        <span class="the-label">Website: </span>
        <span class="the-value"><a href="{{ url($user->website) }}">{{ $user->website }}</a></span>
    </li>
</ul>

有關用戶的所有信息均由控制器提供:

All the information about the user are given by a controller:

public function index($username){
        $user = User::where('username', $username)->first();
        return view('user.profile', compact('user'));
    }

請幫我解決這個問題！

推薦答案

我認為你的 $user->website 是空的/空白的.

I think your $user->website is empty/blank.

如果您查看 url() 輔助方法，如果 $path 為空，Laravel 將返回 UrlGenerator 的實例.

If you look at the url() helper method, Laravel will return an instance of UrlGenerator if $path is null.

所以在你的情況下，如果 $user->website 是空的，你會得到 UrlGenerator 回來，因此你關于 htmlspecialchars 的錯誤得到一個對象.

So in your case if $user->website is empty, you'd get UrlGenerator back and thus your error about htmlspecialchars getting an object.

一個簡單的解決方案是用檢查包裹你的 html 塊:

One simple solution would be to wrap your html chunk with a check:

@if($user->website)
    <li>
        ...
    </li>
@endif
