Php Web表单正在向数据库提交空白数据

我正在尝试使用PHP将数据从web表单发送到数据库。用户在文本框中输入其

全名

、

联系电话

和

最佳通话时间

详细信息。当框中填充了相关信息并点击submit时，数据会被添加到数据库中，只要列是空的。我如何解决这个问题

HTML

 <form name="frmContact" action="<?php $_PHP_SELF ?>" id="frmCallContact" method="POST">
    enter code here<table width="100%" border="0" cellspacing="1" cellpadding="0" class="TableFormat">
        <tr>
         <th align="left" valign="top" colspan="2">Call me back</td>
       </tr>         
       <tr>
         <td align="right" valign="top">Full Name:</td>
         <td><input type="text" name="FullName" id="FullName_R" style="width:250px;" title="Please enter your full name"/></td>
       </tr>
       <tr>
         <td align="right" valign="top">Contact Number:</td>
         <td><input type="text" name="ContactNumber" id="ContactNumber_R" style="width:250px;" /></td>
       </tr>
     <tr>
         <td align="right" valign="top">Best Time to Call:</td>
         <td><input type="text" name="BestTime" id="BestTime_R" style="width:250px;"  title="Please enter your best time to call"/></td>
       </tr>
       <tr>
         <td align="right" valign="top">&nbsp;</td>
         <td><!--<a name="submit" href="#"><img src="/img/bn_submit.png" width="93" height="28" /></a>--><input type="submit" name="Submit" value="Submit">
       </tr>
     </table>
</form>

您的表单包含以下内容：'name=“FullName”'并且在PHP代码中使用：'full\u name'。使用print\u r（$\u POST）；看看你得到了什么。你所说的“数据添加到数据库中非常好，只是列是空的”是什么意思？如果数据添加得很完美，列就不应该是空的，对吗？@sandepnayak我的意思是连接很好，所以我可以将数据提交给我的database@Pakspul非常感谢。我没有意识到它们不匹配。与@Pakspul在其他字段中指出的错误相同。
