我有一個帶有文本輸入和文件上傳的表單。下面我寫的代碼基本上可以工作（需要額外的功能，我會在單獨的問題中詢問），但是我想知道是否有更簡潔，更簡潔的方式來編寫它。我是全新的PHP和任何幫助將不勝感激。多種輸入類型的PHP表單驗證
如果有人試圖提交表單並且字段爲空，或者如果選擇的文件類型不是正確的類型或大小，我想要顯示每個輸入的錯誤消息。在下面的代碼中，我顯示了一條獨特的消息，但是如果有某種方法可以讓代碼更好，那麼我可以說「必需」。
我試過使用jQuery驗證插件，無法讓它與文件上傳一起工作（這超出了我對jQuery/Ajax/PHP的理解），所以這是我想出的解決方案。

據我所知，你應該把東西到變量只是爲了使它更加明顯它是什麼，你做的事。所以我會說不，雖然我確定有清理它的框架。然而，我通常不會打擾並接受PHP有時會有些混亂。 –
請嘗試一些教程，如http://buildinternet.com/2008/12/how-to-validate-a-form-complete-with-error-messages-using-php-part-1/ http： //www.daniweb.com/web-development/php/threads/186170/php-file-upload-validation-before-the-file-uploads –
@dianuj謝謝，它看起來像該教程的邏輯幾乎是什麼我做到了。我確實使用了各種教程來提出這個解決方案。 – surfbird0713
