在我的聯繫表中，我想顯示「」發送的消息，感謝您與我們聯繫！「在用戶按下「發送」按鈕後的容器底部。我已將PHP變量包含在我的HTML中的div標記中。但是當我按下發送它去到一個空白的白頁而不是停留在同一頁上並顯示消息。可能是什麼問題？按'發送'後PHP變量不打印

你在表單標籤，這將提交表單後form_process.php重定向書面行動=「form_process.php」。那麼，它是在哪個文件名中寫入了php代碼？ –
因此，您的空白頁面可能有很多原因。你確定你通過了所有的驗證嗎？ – vbrmnd
您可以改爲使用[Ajax]（https://en.wikipedia.org/wiki/Ajax_（編程））發佈表單。然後，你仍然會在同一頁面上，並可以做任何你想要的東西，當它張貼。 –
