Question

我是PHP表单处理的新手，除了使用Checkboxes处理PHP之外，我已经很好地处理了它。

我遇到的问题是我似乎无法从我的问题中回答出正确的3个答案。我会在我的测验中完成表格，勾选正确的三个复选框，由于某种原因PHP输出说我输错了答案！希望你能提供帮助，任何答案都将不胜感激！：）

这是我的表格和问题：

    <p> 22. What professional golfers have won the masters?</p>

<input type="checkbox" name="golfer" value="a">Tiger Woods<br />
<input type="checkbox" name="golfer" value="b">Phil Mickelson<br />
<input type="checkbox" name="golfer" value="c">Lee Westwood<br />
<input type="checkbox" name="golfer" value="d">Bubba watson<br />

这是我的PHP，我确定这是完全错误的，但希望你知道我想要实现的目标：

if ($golfer == "a" && "b" && "d") {
    echo "That's the right answer, Tiger Woods, Phil Mickelson and Bubba Watson have all won the Masters.";
} else {
    echo "That's the wrong answer. Lee Westwood has not won a major."; 
}

Answer 1

尝试

<input type="checkbox" name="golfer[]" ...

然后$golfer将是PHP中的数组，您可以与正确的值进行比较

以下PHP代码将检查提交的答案是否为'a', 'b', 'd'

sort($golfer);
$correct = array('a', 'b', 'd');

if ($golfer== $correct) {
    echo "That's the right answer, Tiger Woods, Phil Mickelson and Bubba Watson have all won the Masters.";
}

Answer 2

将复选框设为数组

<input type="checkbox" name="golfer[]" value="a">Tiger Woods<br /> 
<input type="checkbox" name="golfer[]" value="b">Phil Mickelson<br />
<input type="checkbox" name="golfer[]" value="c">Lee Westwood<br />
<input type="checkbox" name="golfer[]" value="d">Bubba watson<br />

表单提交后

// The array will only contain the checked value of forms
foreach($golfer as $g) {
   // can use checkbox value here
}

php表单处理多个复选框
