【问题描述】：
我已经设置了一个注册表单，但我的提交按钮无法通过注册信息填充我的数据库。代码片段显示了我的表单的开头以及其中包含的一些字段。
我在表格而不是表格中设置了它，它似乎可以工作，但是当我将其更改为表格时它停止工作。我在这里查看了其他一些链接，例如HTML PHP Contact Form - Submit Button Not Working? Or PHP Issue?，但我似乎无法使其正常工作。
<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 非常新的不完整帖子感到抱歉

这是我用来填充数据库的全部 PHP 脚本。 //Registration point 注释下方的所有内容都应该像我在其上方添加任何内容之前一样正常工作。
【问题讨论】：
-
“它停止工作”。什么停止工作：您的表单停止提交或您的 php 脚本没有看到表单变量。如果是后者，您能否展示您应该处理表单提交的 PHP 代码？

I have set up a registration form and my submit button won't pass through to populate my database with the registration information. The code snipet shows the start of my form and some fields that are included in it.--> 然后检查你的数据库入口代码，因为在我的情况下你的代码正在提交。还有一件事，请发布完整的工作，您不能输入 html 语法并询问为什么我的数据库条目不起作用.. -
我在下面添加了我的 php 代码，并尝试将 method="post" 添加到表单标签，但它仍然不起作用。
