标签： php header

我在成功注册后重定向页面，代码正在正常工作，但标题功能不起作用＆amp;页面不重定向。页面没有重定向。我的代码如下所示

  <?php

    $email=$_POST["tb_email"];
    $pass=$_POST["tb_pass"];
    $repass=$_POST["tb_repass"];
    $contact=$_POST["tb_contact"];

    $select_email=mysql_query("select email from user_reg where email='$email'");
    $rows=mysql_fetch_row($select_email);
    $e_id=$rows[0];

    if(!$email==$e_id && $pass==$repass)
    {
        $insert="insert into user_reg ( fname ,email ,password ,contact,Activation)    values      ('$fname' , '$email' , '$pass' ,'$contact' ,'$activation')";

输出内容后无法发送标题。在这里，您将在PHP标记之前输出whitespcace：

  <?php
^^ remove this whitespace

检查错误日志，你会发现：

  

警告：无法修改标头信息 - 已发送的标头

您的重定向代码后应该有exit;。请参阅this comment。

答案 2 :(得分：1)

尝试使用输出缓冲区

<?php ob_start() ?>

位于此代码的顶部

答案 3 :(得分：1)

使用它。它对我有用。将此函数放在代码顶部：

function move_to(){
    header("Location:page_example.php");
}

并在任何地方调用该函数：

move_to()

使用headers_sent函数来检测问题。 http://php.net/manual/en/function.headers-sent.php

  

检查标头是否或已经发送到哪里。

     

您不能使用header（）函数添加任何标题行一次   标题块已经发送。使用此功能，您可以在   至少可以防止获得与HTTP头相关的错误消息另一个   选项是使用输出缓冲。

// An example using the optional file and line parameters, as of PHP 4.3.0
// Note that $filename and $linenum are passed in for later use.
// Do not assign them values beforehand.
if (!headers_sent($filename, $linenum)) {
    header('Location: http://www.example.com/');
    exit;

// You would most likely trigger an error here.
} else {

    echo "Headers already sent in $filename on line $linenum\n" .
          "Cannot redirect, for now please click this <a " .
          "href=\"http://www.example.com\">link</a> instead\n";
    exit;
}

?>

p.s：也看看“DEMO”;在你的代码中，它应该在行的开头，不应该吗？ 重定向后使用exit。 删除之前的空格
