我已经设置了一个注册表单，我的提交按钮不会通过注册信息填充我的数据库。代码snipet显示了表单的开头以及包含在其中的一些字段。
我把这个设置在一个表中，而不是一个表单，它似乎工作但是当我把它改成一个表格时它停止工作。我已经看过这里的一些其他链接，比如这个HTML PHP Contact Form - Submit Button Not Working? Or PHP Issue?但是我似乎无法让它发挥作用。
<div class = "contact">
<form class="form-horizontal" role="form" method="post" action=" <?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?> ">
<div class="form-group">
<label for="name" class="col-sm-2 control-label">Username:</label>
<div class="col-sm-10">
<input type="text" class="form-control" id="username" name="username" value="<?php echo $username ?>">
<span class="error"><?php echo getErrorMessage('username', $error); ?></span>
</div>
</div>
<div class="form-group">
<label for="password" class="col-sm-2 control-label">Password:</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="password" name="password" value="<?php echo $password ?>">
</div>
</div>
<div class="form-group">
<label for="conPass" class="col-sm-2 control-label">Confirm Password:</label>
<div class="col-sm-10">
<input type="password" class="form-control" id="conPassword" name="conPassword" value="<?php echo $conPass ?>">
</div>
<div class="col-sm-10">
<input id="button" name="reg" type="submit" value="Register" class="btn btn-primary">
</div>
</div> <!-- registration button -->
</form>
</div> <!-- registration end -->
编辑：我的表单在我尝试验证后停止向数据库提交信息，对于Stack Overflow非常新的不完整的帖子感到抱歉

这是填充数据库的总PHP脚本。在注册点注释之下的所有内容都应该在我添加任何内容之前工作。
答案 0 :(得分：0)
我没有在我的文档顶部声明$ password和$ conPass的变量，而这是阻止提交按钮无法工作的原因。
