我試圖用 PHP 撰寫簡單的表單驗證。如果名稱為空，則單擊提交按鈕時，網站將要求用戶填寫。但是當我單擊提交按鈕時，螢屏上沒有任何顯示。你能幫我解決這個問題嗎？謝謝你。這是我的代碼：
<?php
if (isset($_POST["submit"])){
if(!empty($_POST["Ename"])){
}else{
echo"Please enter your name";
}
}
?>
<html>
<form class="" action="index.php" method="post">
Tutor name: <input type="text" name="Ename" value="">
<input type="button" class="submit" value="Submit your record" name="submit">
</form>
</html>

<input>在<form>標簽中寫入標簽并設定輸入type="submit"
<?php
if (isset($_POST["submit"])) {
if (!empty($_POST["Ename"])) {
} else {
echo "Please enter your name";
}
}
?>

您需要將表單輸入和提交按鈕包裝在一個<form>標簽中，如下所示：
<html>
<form method="post">
Tutor name: <input type="text" name="Ename" value="">
<input type="button" class="submit" value="Submit your record" name="submit">
</form>
</html>
