我希望有人可以对这个问题有所了解。我创建了一个注册表单，提交到第二页进行验证。有各种检查来捕获错误和不需要的用户输入，并且无法检查空字段..即使所有字段都包含数据，它仍然被返回为空
这是我的表单 - 注意它确实包含一个隐藏字段，建议使用/＆gt;而不是通常的＆gt;标签 - 两种方式没有区别
<form id="registersocial" class="SRF" name="registersocial" action="php.includes/rasocial.inc.php" method="POST">
<div id="formheaders"><strong>Personal Details</strong></div>
<br/>
<fieldset>
<lable><strong>First Name</strong><br/>
<input type="text" name="firstname" id="firstname" class="SRF" onKeyup="restrict('firstname')" placeholder="First Name" >
<span id="Errmsg-first"></span>
</lable>
<br/>
<lable><strong>Last Name</strong><br/>
<input type="text" name="lastname" id="lastname" class="SRF" onKeyup="restrict('lastname')" placeholder="Last Name" >
<span id="Errmsg-last"></span>
</lable>
<br/>
</fieldset>
<fieldset>
<lable><strong>Date of Birth</strong><br/>
<select name="birthmonth" id="birthmonth" class="SRF">
<?php require("php.includes/month.inc.php"); ?>
</select>
<span id="Errmsg-mob"></span>
<input type="text" name="birthday" id="birthday" class="SRF" maxlength="2" placeholder="Day">
<span id="Errmsg-dob"></span>
<input type="text" name="birthyear" id="birthyear" class="SRF" maxlength="4" placeholder="Year">
<span id="Errmsg-yob"></span>
</lable>
<br/>
</fieldset>
<fieldset>
<lable><strong>Location</strong><br/>
<select name="country" id="country">
<?php require("php.includes/countrylist.php"); ?>
</select>
<span id="Errmsg-country"></span>
</lable>
<br/>
</fieldset>
<hr class="SRF">
<div id="formheaders"><strong >Account Information</strong></div>
<br/>
<fieldset>
<input type="hidden" name="accounttype" id="accounttype" class="SRF" value="Social"/>
<lable><strong>Create a Username</strong><br/>
<input type="text" name="username" id="username" class="SRF" onKeyup="restrict('username')" onblur="checkusername()" placeholder="Username" >
<span id="Errmsg-username"></span>
</lable>
<br/>
<lable><strong>Your Current Email</strong><br/>
<input type="email" name="email" id="email" class="SRF" onKeyup="restrict('email')" placeholder="Your Email" >
<span id="Errmsg-email"></span>
</lable>
<br/>
<lable><strong>Create a Password</strong><br/>
<input type="password" name="pwd" id="pwd" class="SRF" placeholder="Password" >
<span id="Errmsg-password"></span>
</lable>
<br/>
<br/>
<input type="submit" id="submit" name="submit" value="submit">
</fieldset>
<br/>
<span id="status"></span>
<br/>
</form>
下面是获取发布数据并通过验证文件名运行的文件是rasocial.inc.php - 再次我的问题是，在完成表单后，我在网址中收到一个空错误 - 我相信它是简单但却看不到我的生活
