我无法弄清楚我的代码有什么问题。我是php的新手,所以有人可以告诉我我做错了什么吗?
这是表格:
/etc/environment
这就是表单动作。此表单将以第一种形式处理任何输入数据:
<center><br/><h2>Update Form</h2></center>
<div id="login">
<fieldset>
<legend><h3>Update Form</h3></legend>
<h4 style="color:pink;"><?php global $nam; echo $nam;?> </h4>
<?php global $error; echo $error;?>
<!-- the login form-->
<form action='login_reg_action.php' method='post' id='myform'>
<div class="login">
<table width="400px">
<tr>
<td><label>Username</label></td>
<td colspan="2"><span class="style8">
<div align="center">
<?php
include 'connection.php';
$sql = 'SELECT * FROM login_1 ORDER BY username';
$sele=mysqli_query($conn,$sql);
?>
<select name="login_id" style="width:250px; height:34px; border:1px solid #336666;">
<option required="required" value="000" > [SELECT STUDENT]</option>
<?php
while($numu=mysqli_fetch_array($sele))
{
?>
<option required="required" value="<?php echo $numu['login_id'];?> "> <?php echo $numu["login_id"];echo' - ';echo $numu["username"] ?> </option>
<?php
}
?>
</select>
</label>
</div>
</td>
</tr>
<tr>
<td><label>Rank</label></td>
<td><select name="rank" id="rank" style="width:250px; height:34px; border:1px solid #336666;">
<option value="000">Choose user rank</option>
<option value="student">Student</option>
<option value="candidate">Candidate</option>
<option value="administrator">Administrator</option>
</select></td>
</tr>
<tr><td colspan="2" align="left"><input type="submit" name="submit" value="Update" style="width:100px; height:34px; border:1px solid #336666; border-radius:4px;"></td></tr>
</table>
</div>
</form>
