如何獲得 <input> 使用PHP從HTML表單獲取值並將其寫入文本文件
[英]How to get the <input> values from a HTML form using PHP and write values in a text file
問題描述
我有這個html代碼，其中包含我使用bootstrap.創建的表單（其中是登錄表單） bootstrap. 我有這個hi.php文件來獲取用戶輸入的詳細信息（ 電子郵件和密碼 ）。 但是我不確定自己做錯了什么，因為即使登錄后文件（ details.txt ）還是空的。
HTML：
<!DOCTYPE html>
<html lang="en">
<head>

<div class="checkbox">

</div>
<button class="btn btn-lg btn-primary btn-block" type="submit">Sign in</button>
</form>
</div> <!-- /container -->

<script src="../../../../assets/js/ie10-viewport-bug-workaround.js"></script>
</body>
</html>
這是我的PHP ：
<?php
$handle = fopen("details.txt", "a");
foreach($_POST as $variable => $value) {
fwrite($handle, $variable);
fwrite($handle, "=");
fwrite($handle, $value);
fwrite($handle, "\n");
}
fwrite($handle, "\n");
fclose($handle);
exit;
?>
誰能告訴我我在哪里做錯了？？？

問題出在您的表單輸入字段。 您尚未為輸入字段指定名稱，這就是為什么它未在$ _POST中設置值
