兴趣爱好中的问题，因为无法使用PHP获取选定的值

Question

我在顶部提供了pre标签，以便我可以在单击ragister按钮时查看正在运行的值，除业余爱好外，所有值都将正确运行，因为它会给“ on”一个字，为什么，请告诉我，我是php的新手请尽我所能详细解释。

<?php

$error_array = array();
$fname = $lname = $email = $dob = $Mchecked = $Fchecked = $hobbies ="";

if(isset($_POST["sbt_save"]))
{   
echo '<pre>'; print_r($_POST); echo "</pre>";
    if($_POST['fname']=="")
    {           
        $err ="Please Enter your first name"."<br>";
        array_push($error_array,$err);
    }
    else
    {
        $fname = test_input($_POST['fname']);
    }

    if($_POST['lname']=="")
    {
        $err ="Please Enter your last name"."<br>";
        array_push($error_array,$err);
    }
    else
    {
        $lname = test_input($_POST["lname"]);
    }

    if($_POST['email']=="")
    {       
        $err ="Please Enter your email"."<br>";
        array_push($error_array,$err);
    }
    else
    {
        $email = test_input($_POST["email"]);
    }

    if($_POST['dob']=="")
    {
        $err ="Please Enter your date of birth"."<br>";
        array_push($error_array,$err);
    }
    else
    {
        $dob = test_input($_POST["dob"]);
    }

    if(!isset($_POST["gender"]))
    {
        $err ="Please select gender"."<br>";
        array_push($error_array,$err);
    }
    else
    {
        $gender = $_POST["gender"];
        if ($gender == "Male")
        {
            $Mchecked = "checked";
        }
        else if ($gender == "Female")
        {
            $Fchecked = "checked";
        }
    }

    if(!isset($_POST['hobbies']))
    {
        $err ="Please Enter your hobbies"."<br>";
        array_push($error_array,$err);
    }
    else
    {
        $hobbies = test_input($_POST['hobbies']);
    }

}


function test_input($data)
{
   $data = trim($data);
   $data = stripslashes($data);
   $data = htmlspecialchars($data);
   return $data;
}

Answer 1

您需要将值属性添加到复选框元素：

 <tr>
<td class="field_Name">Hobbies :<b style="color:red">*</b></td>
<td><input name="hobbies" value="cricket" type="checkbox" id="hobbies"  class="inputfield_Name" />Cricket
    <input name="hobbies" value="singing" type="checkbox" />Singing
    <input name="hobbies"  value="travelling" type="checkbox" />Travling</td>
<tr>
<td></td>
<td>
    <input name="hobbies"  value="writing" type="checkbox"  class="inputfield_Name"/>Writing
    <input name="hobbies"  value="teaching" type="checkbox" />Teaching
    <input name="hobbies"  value="driving" type="checkbox" />Driving
</td>
</tr>
