我有这个代码,为什么我的标题位置不起作用？它是一种更新,编辑和删除我的控制面板中的一些页面的形式...我在form.php的同一个文件夹中有一个index.php文件...有什么帮助吗？()我试着把标题放在后面编辑和删除...仍然转到表单页面而不是索引...
<?php
include "../../includes/site_includes.php";
//send
if ((isset($_POST["send"])) && ($_POST["send"] == 1)) {
$pageid = $_POST["page_id"];
$pagetitle = $_POST["page_title"];
$nameinmenu = $_POST["page_menu_name"];
$nameinurl = $_POST["page_name_url"];
$link = $_POST["page_link"];
$picture = $_POST["page_pic"];
$desc = $_POST["page_desc"];
$content = $_POST["page_content"];
}
if ((isset($_POST["act"])) && ($_POST["act"] == "add")) {
$sql = insertpage();
if ($result = $mysqli->prepare($sql)) {
$result->bind_param("sssssss", $pagetitle, $nameinmenu, $nameinurl, $link, $picture, $desc, $content);
$result->execute();
$result->store_result();
$rows = $result->num_rows;
}
}
////edit
if ((isset($_GET["act"])) && ($_GET["act"] == "edit")) {
$sql = getfrompages();
if ($result = $mysqli->prepare($sql)) {
$rekza = $_GET["id"];
$result->bind_param("i", $rekza);
$result->execute();
$result->store_result();
$rowsZ = $result->num_rows;
}
if ($rowsZ > 0) {
$row = fetch($result);
$pageid = $row[0]["page_id"];
$pagetitle = $row[0]["page_title"];
$nameinmenu = $row[0]["page_menu_name"];
$nameinurl = $row[0]["page_name_url"];
$link = $row[0]["page_link"];

$desc = $row[0]["page_desc"];
$content = $row[0]["page_content"];
}
}
if ((isset($_GET["act"])) && ($_GET["act"] == "delete")) {
$thedelid = $_GET["id"];
$sql2 = delpage();
if ($result2 = $mysqli->prepare($sql2)) {
$result2->bind_param("i", $thedelid);
$result2->execute();
$result2->store_result();
$rowsZ2 = $result2->num_rows;

解决: 用@ Mihai Iorga代码我添加了ob_start();

那是因为你有一个输出:
?>
<?php
导致空行输出.
必须在发送任何实际输出之前调用header(),无论是普通HTML标记,文件中的空行还是PHP
合并所有PHP代码,并确保文件开头没有任何空格.
如果您还有其他任何脚本,请在header('location: index.php');添加之后exit();.
也可以在最后一个之后移动重定向标题if.

删除空间
正确:标题("位置:home.php"); 或标题("Location:home.php");
不正确:标题("Location:home.php");
删除位置和:- >标题之间的空格("位置(删除空格):home.php");
函数ob_start()将打开输出缓冲.当输出缓冲处于活动状态时,不会从脚本(标头除外)发送输出,而是将输出存储在内部缓冲区中.因此浏览器将不会收到任何输出,并且标题将起作用.我们还应确保在代码顶部使用header().
ob_start();
应添加到第 1 行本身。就像下面的例子一样
<?php
ob_start(); // needs to be added here
?>
<!DOCTYPE html>
<html lang="en">
// your code goes here
</html>
<?php
if(isset($_POST['submit']))
{
//code to save data in db goes here
}
header('location:index.php?msg=sav');
?>
将其添加到 html 下面也不起作用。像下面这样
<!DOCTYPE html>
<html lang="en">
// your code goes here
</html>
<?php
ob_start(); // it doesnt work even if you add here
if(isset($_POST['submit']))
{
//code to save data in db goes here
}
header('location:index.php?msg=sav');
?>
