PHP 不發布我的表單值

Question

我已經撓了一個小時了，不明白為什么 php 不發布我的表單值。

代碼

        <!-- Login -->
        <div class="login__block toggled" id="l-login">
            <div class="login__block__header">

請注意，我對 PHP 非常陌生，如果您能幫助我，這對我來說意味着整個世界！ 謝謝你。

Answer 1

提交按鈕僅在表單標簽內時才有效。 你的代碼沒有任何表單標簽試試這個

  <form action="" >
        <!-- Login -->
        <!--your code here -->
  </form>

Answer 2

添加這樣的表單屬性

<div class="login__block__body"> 
  <form action="url which will process form" method="POST">
                <div class="form-group form-group--float form-group--centered form-group--centered">
                    <input type="text" class="form-control" name="email">
                    <label>Email Address</label>
                    <i class="form-group__bar"></i>
                </div>

                <div class="form-group form-group--float form-group--centered form-group--centered">
                    <input type="password" class="form-control" name="password">
                    <label>Password</label>
                    <i class="form-group__bar"></i>
                </div>

                <button type="submit" class="btn btn--light btn--icon m-t-15"><i class="zmdi zmdi-long-arrow-right"></i></button>
     </form>

            </div>

Answer 3

所有<input>標簽都必須在<form>標簽內。

<form action="" method="post"> //Submits form to same page
<input/>
<input/>
<button type="submit" class="btn btn--light btn--icon m-t-15"><i class="zmdi zmdi-long-arrow-right"></i></button>
</form>

當您“提交”此表單時，它將 POST 表單中的所有輸入值，您可以從$_POST['name_of_input']變量中檢索這些值

我建議在 PHP 之前學習 HTML。
