我正在用 PHP 创建一个更高或更低的游戏，到目前为止一切都已完成，但我在 POST 方面遇到了问题。
基本上，当用户编译所有 3 个字段（选择、赌注和数字）并按下“开始”时，不会显示任何内容。没有赢/输/平局消息或任何东西。
这是整个代码：
<form action="" method="post">
<div id="test-container">
<select class="form-control" id="choice" name="choice">
<option value="">Select 'High' or 'Low'...</option>
<option value="1">High</option>
<option value="2">Low</option>
</select>
<br>
<?
echo "<select class=\"form-control\" id=\"bet\" name=\"bet\">";
echo "<option value=\"\">Please place your bet...</option>";
for($bet = 1; $bet <= 50; $bet++) echo "<option value='$bet'>$bet</option>";
echo "</select>";
?>
<br>
<?
echo "<select class=\"form-control\" id=\"number\" name=\"number\">";
echo "<option value=\"\">Please select a number...</option>";
for($number = 1; $number <= 100; $number++) echo "<option value='$number'>$number</option>";
echo "</select>";
?>
</div>
<br><br><button id="submit" type="submit" type="button" name="play" class="btn btn-primary">Play!</button>
<?
if(isset($_POST['play']))
{
$invalid_choice = 0;
$invalid_bet = 0;
$invalid_number = 0;
$won = 0;
$choice = $_POST['choice'];
$bet = $_POST['bet'];
$number = $_POST['number'];
$random_number = rand(1, 100);
$rhash = generateRandomString();
if(!$choice)
{
$invalid_choice = 1;
echo "<br><br>" . "<div class=\"alert alert-danger\" role=\"alert\">Please select 'High' or 'Low'</div>";

我已经尝试了一切，检查了变量等等。
我已经编辑了 if(!$invalid_choice 等) 代码以减少它并使用更少的查询，但现在行甚至没有插入到数据库中，并且即使在表单后回显后仍然不显示消息。 :|
