如何從收音機中選擇 select 並顯示它？

Question

這是我的代碼，我無法顯示在收音機中選擇的選項。 我使用引導程序制作了單選框，甚至使用了 HTML 代碼

<form method="post">
    <div class="col-sm-2">
                <label for="gender" class="gender">Gender:</label><br>
                <div class="form-check form-check-inline">
                <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1">
                <label class="form-check-label" name="male" for="inlineRadio1" id="male">Male</label>
              </div>
              <div class="form-check form-check-inline">
                <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2">
                <label class="form-check-label" name="female" for="inlineRadio2" id="female">Female</label>
              </div>
            </div>  <input class="btn btn-outline-info" name="btnsubmit" type="submit" value="Submit" id="submit2">
</form>

PHP 代碼

<?php
echo "hello";
if (isset($_POST['btnsubmit']))
{
  echo $_POST['inlineRadioOptions'];
}
?>

Answer 1

你沒有使用表格

<form action="#" method="POST">
   <input type="radio" name="radioBTN" id="" value="Hello World">
   <input type="submit" name="signup">
</form>

<?php 
if(isset($_POST['signup'])) echo $_POST['signup'];
 ?>

Answer 2

使用帶有提交按鈕值的表單標簽執行此操作，並通過 print_r() 檢查發布數據；

HTML 代碼

<form name="UserForm" method="POST">

<div class="col-sm-2">
            <label for="gender" class="gender">Gender:</label><br>
            <div class="form-check form-check-inline">
            <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1">
            <label class="form-check-label" name="male" for="inlineRadio1" id="male">Male</label>
          </div>
          <div class="form-check form-check-inline">
            <input class="form-check-input" type="radio" name="inlineRadioOptions" id="inlineRadio2" value="option2">
            <label class="form-check-label" name="female" for="inlineRadio2" id="female">Female</label>
          </div>
        </div>  <input class="btn btn-outline-info" name="btnsubmit" type="submit" value="Submit" id="submit2">

</form>

PHP 代碼

<?php
 // print_r($_POST); // Optional for Checking Value
if (isset($_POST['btnsubmit']) && $_POST['btnsubmit'] == "Submit")
{
  echo "hello";

  echo $_POST['inlineRadioOptions'];
}
?>
