Question

我有一个带3个单选按钮的引导程序表单。我将值保存到变量中，以便我可以用来保存到数据库和电子邮件中。

HTML：

<form class="form-horizontal form-validate" id="signup-form" method="post">
<input type="hidden" name="signupForm" />

<div class="control-group">
  <label class="control-label">Seed program</label>
  <div class="controls">
  <input type="radio" name="signup" value="Seed Program" checked="checked"/>
  </div>
</div>

<div class="control-group">
  <label class="control-label">Gift Wrap Program</label>    
  <div class="controls">
  <input type="radio" name="signup" value="Gift Wrap" />
  </div>
</div>

<div class="control-group">
  <label class="control-label">Sign up for both</label> 
  <div class="controls">
  <input type="radio" name="signup" value="Both" />
  </div>
</div>

<input type="submit" class="btn btn-large btn-block btn-success" value="Submit" name="submit">
</form>

PHP：

if(isset($_POST['signupForm'])){

  if(isset($_POST['signup'])) {
    $signup = $_POST["signup"];
  }
  else{
    $signup = "Nothing was selected";
  }

}

问题：

问题是我只能获得具有“已检查”属性的第一个单选按钮的值。如果我选择其他两个中的任何一个，我什么都得不到，值显示为空。

感谢任何帮助。

谢谢，

尝试使用

 <input type="radio" name="signup" value="Seed Program" checked="checked"/>

而不是

<?php 
$selected_admin = find_admin_by_id($_GET["admin"]); 
if (!$selected_admin) { redirect_to("sadmin.php"); 
} 
while ($admin = mysqli_fetch_assoc($selected_admin)) 
{ 
$admin_id = $admin["admin_id"]; 
} 

if( intval($admin_id) > 0 ){
$sql = "delete from admin where admin_id = {$admin_id} limit 1";

$result = mysqli_query($connection, $sql); 

if ($result && mysqli_affected_rows($connection) == 1) 
{ 
$SESSION["message"] = "Admin successfully deleted.";

 redirect_to("sadmin.php"); 
} 
else { 
$SESSION["message"] = "Admin was not deleted successfully."; redirect_to("sadmin.php?admin={$admin_id}"); 
}
}
 ?>

PHP：Bootstrap单选按钮值未显示
