Answer 1

你需要2个if语句，一个说“表单是提交吗？”，还有一个说“是否有错误信息？”

<input name="Submit" type="submit" class="submitbtn" value="Submit" />
    <?php if(isset( $_POST['Submit']) {
        if($msg!='')
    {?>
        <div class="erroroutput"><p><?php echo $msg; ?><br></p></div>

    <?php } else{?>
    <div><center><h2>Thank you for submission</h2></center></div>
    <?php }
    }?>

Answer 2

像那样改变

<input name="Submit" type="submit" class="submitbtn" value="Submit" />
    <?php if(isset( $_POST['Submit']) && $msg=='' )
    {?>
        <div><center><h2>Thank you for submission</h2></center></div>            
    <?php } else{?>
        <div class="erroroutput"><p><?php echo $msg; ?><br></p></div>        
    <?php }?>

Answer 3

试试这个，

使用两个条件。

<?php if(isset( $_POST['Submit'])
      {
      if( $msg!='')
      {?>
        <div class="erroroutput"><p><?php echo $msg; ?><br></p></div>

    <?php } else{?>
    <div><center><h2>Thank you for submission</h2></center></div>
    <?php }
     }?>

Answer 4

你必须在你的else-if循环中检查提交任务。

用以下代码替换您的代码：

<input name="Submit" type="submit" class="submitbtn" value="Submit" />
        <?php if(isset( $_POST['Submit']) && $msg!='' )
        {?>
            <div class="erroroutput"><p><?php echo $msg; ?><br></p></div>

        <?php } elseif (isset( $_POST['Submit'])) { ?>
        <div><center><h2>Thank you for submission</h2></center></div>
        <?php }?>
</form>

<input name="Submit" type="submit" class="submitbtn" value="Submit" />
<?php if(isset( $_POST['Submit']) && $msg!='' ){?>
     <div class="erroroutput"><p><?php echo $msg; ?><br></p></div>
<?php } else if(isset($_POST['Submit]){?>
        <div><center><h2>Thank you for submission</h2></center></div>
<?php }?>
