Question

为什么这不起作用或我只是愚蠢？它没有打印任何东西，单击按钮后页面看起来完全一样（我有<form>以及我实际代码中的所有内容）

<html>

<input type="radio" name = "gender" value = "male">
<input type="radio" name = "gender" value = "female">

<input type="radio" name = "race" value = "asian">    

<?php
if(isset($_POST["Button"]))
{

if(($_POST["gender"] == "male") && ($_POST["race"] == "asian"))
{
 echo "you are male and asian";
}

}
?>

</html>

与它有关的整个代码区域如下所示：

<html>
<center>
<body>

<form method=post action= "">
<br>
<br>
Name: <input type="text" name="username">
<br>
<br>
<br>

I am:

<br>
<br>
<input type="radio" name = "gender" value = "male"> Male &nbsp; &nbsp;

<input type="radio" name = "gender" value = "female"> Female
<br>
<br>
</form>




<form method=post action= "">

Ethnicity:

<br>
<br>
<input type="radio" name = "race" value = "asian">Asian
<br>
<br>
<input type="radio" name = "race" value = "black">Black
<br>
<br>
<input type="radio" name = "race" value = "white">White
<br>
<br>
<br>
<input type="submit" name="Button" value = "Who will I marry?">


</form>

<?php


if(isset($_POST["Button"]))
{

if(($_POST["gender"] == "male") && ($_POST["race"] == "asian"))
{

?>
congrats!
<?
}
}



?>

</center>

</body>

</html>

Answer 1

您有两个不同的表单标记，而不是一个包含所有字段的表单。

Answer 2

您正在使用两种不同的形式，并引用不同的表单元素。像这样编辑使用单一形式。并使用method="post"代替method=post

<form method="post" action= "">

Name: <input type="text" name="username">


I am:

<input type="radio" name = "gender" value = "male"> Male &nbsp; &nbsp;

<input type="radio" name = "gender" value = "female"> Female



 Ethnicity:

<input type="radio" name = "race" value = "asian">Asian
<br>
<br>
<input type="radio" name = "race" value = "black">Black
<br>
<br>
<input type="radio" name = "race" value = "white">White
<br>
<br>
<br>
<input type="submit" name="Button" value = "Who will I marry?">


</form>

radiobutton是选择PHP
