Question

每当我提交表单时，我都会通过启用php中的错误报告来遇到此错误：

警告：无法修改标头信息 - 已在/ Applications / MAMP / htdocs / cranium / includes / register中发送的标头（输出从/Applications/MAMP/htdocs/cranium/includes/header.inc.php:14开始）第65行的.inc.php

在我的header.inc.php中，我有这段代码：

<!doctype html>
<!--[if lt IE 7]> <html class="no-js lt-ie9 lt-ie8 lt-ie7" lang="en"> <![endif]-->
<!--[if IE 7]>    <html class="no-js lt-ie9 lt-ie8" lang="en"> <![endif]-->
<!--[if IE 8]>    <html class="no-js lt-ie9" lang="en"> <![endif]-->
<!--[if gt IE 8]><!--> <html class="no-js" lang="en"> <!--<![endif]-->
<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
  <title>Cranium eSolutions</title>
  <meta name="viewport" content="width=device-width">
  <link rel="stylesheet" href="/cranium/css/style.css">
  <script src="/cranium/js/libs/modernizr-2.5.3.min.js"></script>
</head>
<body>

我使用include_once在我的页面中包含此代码。（第14行指向body标签，之后没有空格或任何空格。）

在我的register.inc.php中：

<?php
error_reporting(E_ALL); ini_set('display_errors', 'On');
$username = mysql_real_escape_string(stripcslashes($_POST['txtUser']));

//generate password
$password = generatePassword(10,5);


$email = mysql_real_escape_string(stripcslashes($_POST['txtEmail']));

//random code
$com_code = sha1(uniqid(rand()));


$fName = mysql_real_escape_string(stripcslashes($_POST['txtFname']));
$lName = mysql_real_escape_string(stripcslashes($_POST['txtLname']));
$address = mysql_real_escape_string(stripcslashes($_POST['txtAddress']));
$city = mysql_real_escape_string(stripcslashes($_POST['txtCity']));
$zip = (int)$_POST['txtZip'];
$country = $_POST['txtCountry'];
$mobile = mysql_real_escape_string(stripcslashes($_POST['txtMobileNo']));
$office = mysql_real_escape_string(stripcslashes($_POST['txtOfficeNo']));
$specialty = $_POST['txtFOS'];
$prof = $_POST['txtProf'];



//checkbox
$practiceFetch = $_POST['chkSOP'];
$n = count($practiceFetch);
$practice = '';
for ($i = 0; $i < $n; ++$i) {
    $practice .= $practiceFetch[$i].', ';
}
$practice = substr($practice,0,-2);



$coordinator = mysql_real_escape_string(stripcslashes($_POST['txtPrimaryCoord']));
$relationship = mysql_real_escape_string(stripcslashes($_POST['txtRelationship']));
$relEmail = mysql_real_escape_string(stripcslashes($_POST['txtRelEmail']));
$feedback = mysql_real_escape_string(stripcslashes($_POST['txtHow']));

//service concat
//if ($_POST['txtSubService']) $subService = mysql_real_escape_string(stripcslashes(' - '.$_POST['txtSubService']));
//$service = mysql_real_escape_string(stripcslashes($_POST['txtService'])).$subService;
$service = 'tae';


//start Query
require_once('../includes/db.config.php');
$checkQuery = "SELECT username FROM tblAccounts WHERE username='$username'";
$checkResult = mysqli_query($cxn,$checkQuery);
if (mysqli_num_rows($checkResult) <= 0) {
    $query = "INSERT INTO tblAccounts VALUES('','$username','$password','$fName','$lName','$address','$email','$com_code','$city',$zip,'$country',$mobile,$office,'$specialty','$prof','$practice','$coordinator','$relationship','$relEmail','$feedback','$service')";
    $result = mysqli_query($cxn,$query);
    //email confirmation
    $to = $email;
    $subject = "Confirmation from Cranium eSolutions Inc., to $username";
    $header = "Cranium eSolutions Inc.: Confirmation from craniumesolutions.com";
    $message = "Please click the link below to verify and activate your account. <br />";
    $message .= "http://imageworkz.asia/Cranium-Trial/confirm.php?passkey=$com_code";
    $sentmail = mail($to, $subject, $message, $header);
    if($sentmail) {
        header('Location: http://www.google.com');
    } else {
        header('Location: http://localhost/cranium/verificationfail.html');
    }
} else {

    echo '<span style="color:red;">Username already exists</span>';

}
?>

第65行指向标题（'位置：www.google.com。'）;

有什么想法吗？谢谢！

Answer 1

在header()来电之前，您无法输出任何内容。如果正在回复某些内容，或者显示有任何错误，请检查您的代码。

查看header.inc.php第14行。这就是输出内容的地方。

Answer 2

您可以使用输出缓冲区解决此问题。

http://php.net/manual/de/function.ob-start.php

这将缓冲输出，直到您刷新它或脚本完成为止。在=＆gt;之前没有输出没问题！

Answer 3

header.ing.php IS输出。

你运行的分段秒“include（'header.inc.php'）你有输出。

解决方案：稍后运行。

此外，在标题（位置）命令后添加“exit”以停止正在执行的其余脚本。 PHP将继续运行。

php标题位置无法在脚本中运行
