Question

如何纠正数组中的显示数据。我猜这是一个foreach循环，但我不知道如何咬它。我只需要标题。在日历表中。

非常感谢！

@foreach($list as $item)
    {{ $item->header }}
@endforeach

我尝试了上面的代码，但抛出一个错误，未知值“ header”

@foreach($results as $type => $list)
    <div class="single-contact-information mb-30">
        <h3>{{ $type }} </h3>
        {{ $list }}  
    </div>
@endforeach

[{"id":1,"header":"test","description":"<p>test<\/p>","date":"2020-12-12"}]

编辑： SearchController：

public function search(Request $request)
{
    $search = $request->get('search');
    $results = [];
    $results['calendars'] = DB::table('calendars')->where('header', 'like', '%'.$search.'%')->get();

    return view('pages.search', ['results' => $results]);
}

您应该尝试以下操作：

string certlocation = Environment.ExpandEnvironmentVariables("%appdata%\\x\\");
X509Store store = new X509Store(StoreName.Root, StoreLocation.CurrentUser);
var ecdsa = ECDsa.Create(); // generate asymmetric key pair
var req = new CertificateRequest("cn=" + certname, ecdsa, HashAlgorithmName.SHA256);

var cert = req.CreateSelfSigned(DateTimeOffset.Now, DateTimeOffset.Now.AddYears(5));

// Create PFX (PKCS #12) with private key
File.WriteAllBytes(certlocation + certname + ".pfx", cert.Export(X509ContentType.Pfx));

// Create Base 64 encoded CER (public key only)
File.WriteAllText(certlocation + certname + ".cer",
    "-----BEGIN CERTIFICATE-----\r\n"
    + Convert.ToBase64String(cert.Export(X509ContentType.Cert), Base64FormattingOptions.InsertLineBreaks)
    + "\r\n-----END CERTIFICATE-----");
string cerFileName = certlocation + certname + ".pfx";
X509Certificate2 certificate = new X509Certificate2(cerFileName);
store.Open(OpenFlags.ReadWrite);
store.Add(certificate);
store.Close();

上面的值为json，然后使用以下代码

[{"id":1,"header":"test","description":"<p>test<\/p>","date":"2020-12-12"}]

更新后的答案

    $list = [{"id":1,"header":"test","description":"<p>test<\/p>","date":"2020-12-12"}];



@foreach($list as $item)
    {{ $item['header'] }}
@endforeach

    $list = json_decode($list);

    @foreach($list as $item)
        {{ $item['header'] }}
    @endforeach

Answer 2

尝试这个

此处使用的json_decode功能

@foreach(json_decode($list) as $item)
    {{ $item['header'] }}
@endforeach
