答案 0 :(得分：1)
由于似乎没有一个回答者可以在一个答案中得到完全修复，我想我必须这样做。
问题：
以下是您需要的PHP
$Almnus= $_REQUEST["LKGAlumnus"]; // watch the spelling, Get the NAME
以下是带有一个复选框的解决方案
<input type="checkbox" name="LKGAlumnus" value="Yes" id="LKGAlumnusYes" />
<label for="LKGAlumnusYes">Alumnus?</label>
这是带有两个无线电的解决方案
Alumnus?<input type="radio" name="LKGAlumnus" value="Yes" id="LKGAlumnusYes"/>
<label for="LKGAlumnusYes">Yes</label>
<input type="radio" name="LKGAlumnus" value="No" id="LKGAlumnusNo" />
<label for="LKGAlumnusNo">No</label>
答案 1 :(得分：0)
您的拼写错误导致名称不匹配：LKGAlumnus然后LKGAlmnus。第一个有两个u，第二个只有一个。
<input type="checkbox" name="LKGAlumnus" value="Yes" id="LKGAlmnus" >Yes   
<input type="checkbox" name="LKGAlumnus" value="No" id="LKGAlmnus" >No       
//...
$Almnus= $_REQUEST["LKGAlmnus"];
答案 2 :(得分：0)
如果您想获得以下任一选项，则应使用单选按钮而不是复选框：
<强> HTML：
<input type="radio" name="LKGAlumnus" value="Yes" id="LKGAlmnusYes" >Yes</input>
<input type="radio" name="LKGAlumnus" value="No" id="LKGAlmnusNo" >No </input>
<强> PHP：
$Almnus= $_POST["LKGAlumnus"];
