在我的内容执行后,我正在尝试进行PHP重定向,但是我无法让代码执行.
如果我加载它,它会重定向页面,但不会向数据库插入任何内容.如果我注释掉标题重定向行,它会将数据输入我的数据库.
如何让PHP运行并执行,然后重定向页面？
<?php require("gplus.php"); ?>
<?php require("database.php");?>
<?php if(isset($personMarkup)): ?>
<?php
$checkuser = "SELECT gid FROM user WHERE gid = '$id'";
$updateuser = "UPDATE user SET name = '$name', pic = '$img' WHERE gid = '$id'";
$adduser = "INSERT INTO user (gid, name, pic) VALUES ('$id','$name','$img')";
$checkuserrlt = mysqli_query($con, $checkuser);
if(mysqli_num_rows($checkuserrlt) > 0) {
$result = mysqli_query($con, $updateuser) or die(mysqli_error());
} else {
$result = mysqli_query($con, $adduser) or die(mysqli_error());
}
?>
<?php endif ?>
<?
mysqli_close($con);
?>
<?php
header( …我收到以下错误:
警告:无法修改标题信息 - 已在第4行的/home/content/89/11421189/html/notfound.php中发送的标题(在/home/content/89/11421189/html/notfound.php:2处开始输出)
在我的文件'notfound.php'中,它使用以下代码:
<!DOCTYPE html>
<?php//Line 2
ob_start();
header('Location:http://www.website.com/index.php?page=404.php', true, 302);
exit;
?>
<head>
</head>
<html>
</html>
请注意,PHP标记之前或之后没有空格.无论我将它移动到哪里(即使它都在同一条线上),该行是错误的罪魁祸首.我在这做错了什么？
[编辑]注意:如果我将PHP移动到DOCTYPE标记之前,导航到此文件会给出错误403:禁止.位置很好,因为我可以将其复制/粘贴到地址栏中而不会出现问题.你能通过header()传递GET参数吗？
我知道这个问题已被多次询问,但是,我似乎无法找到与我的情况相关的解决方案,因为它们主要处理wordpress.
这是我的邮件表格:

Invite.php
PHP:
<?php
if(isset($_POST['submit'])){
$email = $_POST['email']; }
$length = 10;
$inviteCode = "";
$characters = "0123456789abcdefghijklmnopqrstuvwxyz";

HTML:
<form action="save.php" method="POST">
<div class="form-email">

</form>
save.php:

mysql_query("INSERT INTO referrals (email, inviteCode)

在将信息成功发送到数据库之后,我如何将用户从save.php重定向回invite.php？
我是php的新手,所以任何反馈,评论或帮助都非常感谢,谢谢(Y)
我有一个文件,它启动<?php session_start();?>,并返回一个错误
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\xampp2\htdocs\index.php:1) in C:\xampp2\htdocs\index.php on line 3
现在看看当下,我无法理解当我将我的文件的所有内容复制到另一个文件时,它开始工作.有人可以解释它是如何发生的.谢谢
我没有任何白色空间,至少我看不到它们
<div id="left-body-part-innerpage">
<h1 class="mainheading">Contact Us</h1>

// Insert you code for processing the form here, e.g emailing the submission, entering it into a database.
session_destroy();

?>
我收到警告:session_start()[function.session-start]:无法发送会话缓存限制器 - 网站已经发送(网站开始输出)

谁能帮我？
提前致谢....
我相信你们都知道这个错误:
Warning: Cannot modify header information - headers already sent by (output started at /homepages/4/d374499247/htdocs/wp-content/themes/tyler/mail.php:1) in /homepages/4/d374499247/htdocs/wp-content/themes/tyler/mail.php on line 34
这是代码:
if (strpos($email,'@') !== false) {
ob_start();
mail($to,$subject,$message,$headers);
header("Location: thankyou.html");
ob_end_flush(); }
谁能在这里提供任何帮助？我只想要邮件()信息,然后转到位置页面
编辑:这是整个代码..

但是索引页面上的输出表明会话变量未定义。我该如何解决这个问题，为什么它是未定义的？
