Question

在下面的代码中，我尝试在将值写入数据库后重定向页面。但是一旦写入数据，页面就不会被重定向

代码是

IMPORT EMPLOYEE DETAILS
        </h2>
        <br><br>
        <form method="post" action="import.php" enctype="multipart/form-data">
          <!--  <input type="text" name="excelname"> -->
          Please Choose your excel(in .xls format):  <input type="file" name="file" id="file" class="multifile">
           DATE: <input type="date" name="period" id="date" value="">
            <input type="submit" value="IMPORT" name="submit" class="button">&nbsp;&nbsp;

        </form>
<?php
if($_POST["period"])
{
$Date=$_POST["period"];



  $sql1="INSERT INTO report (report_date) VALUES ('$Date') ";
mysqli_query($connection,$sql1);

}
$Date=NULL;
    $excel = new Spreadsheet_Excel_Reader();

    if(isset($_POST['submit'])){

    $name=$_FILES["file"]["name"];

move_uploaded_file($_FILES["file"]["tmp_name"],
      "excel/" . $_FILES["file"]["name"]);
$upload_name='excel/'.$name;


echo'<br>';

    if($name != null)
    {
    $excel->read($upload_name);
    $x=1;
    while($x<=$excel->sheets[0]['numRows']) {
      echo "\t<tr>\n";
      $y=1;
      $index=0;
      $arr = array();
      while($y<=$excel->sheets[0]['numCols']) {
        $cell = isset($excel->sheets[0]['cells'][$x][$y]) ? $excel->sheets[0]['cells'][$x][$y] : '';
        //echo "\t\t<td>$cell</td>\n";
        if($x>1)
        {
         $arr[$index]=$cell;

          $index++;
        }
        $y++;

      }

    if(!empty($arr))
     {

if(!empty($n1))

{

 $n1=null;
        }

             header('Location: http://localhost/kmtcrg/confirm.php');
    } 
    } 
    ?>

任何人都可以帮助我，我没有在这个

中出错

Answer 1

之前标题不能是任何输出。

将PHP脚本移到HTML上方。

<?php

// your code
header();

?>

Your HTML

Answer 2

您需要使用ob_start read about ob_start

在代码的最开头缓冲

并将你的PHP代码移到顶部，如黑豹建议的那样。所以你的代码看起来更像是

<?php
ob_start(); //using ob_start is a good practice 

// your code
header();

?>

Your HTML

header（）不会将我重定向到另一个页面
