我的 Livewire 有一個奇怪的問題：當我發送檔案時，驗證總是在第一次失敗。如果我有必須是 pdf 的標準，我會放 PDF，提交表單，收到一條訊息，告訴我格式錯誤，我不會更改任何內容，重新提交，它會毫無問題地通過。
有誰知道為什么會發生這種情況？

{
use WithFileUploads;
public BranchDocument $document;
public $file;
public $saved = false;
public function render()
{
return view('livewire.branch.documents.upload');
}
public function save() {
$this->validate([
'file' => 'mimes:jpg,bmp,png,pdf|max:10240', // 1MB Max
]);
$this->document->file = $this->file;
$this->saved = true;

uj5u.com熱心網友回復：
檔案是否在您點擊提交之前上傳？如果不是，則檔案為空，因此格式錯誤。在驗證之前檢查其在 save 方法中的值。您還可以wire.loading在 div 上使用以確定檔案是否仍在上傳。
您也可能會遇到內置的 artisan 開發服務器（從php artisan serve命令開始的那個）的問題。它對“真實”服務器有不同的限制——上傳檔案大小、格式等。
