标头位置在我的php代码中不起作用

php

我有此代码,为什么我的标题位置不起作用?它是一种在我的控制面板中更新,编辑和删除某些页面的形式…并且我在form.php的同一文件夹中有一个index.php文件…任何帮助吗?()我试图将标题放在编辑和删除…并且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"];
        $picture = $row[0]["page_pic"];
        $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;
    }
}
header('location: index.php');
exit();
?>

解决: 使用@ Mihai Iorga代码,我添加了ob_start();

那是因为您有一个输出:

?>
<?php

导致空白行输出。

在发送任何实际输出之前,必须通过常规HTML标记,文件中的空白行或从PHP中调用header()

合并所有PHP代码,并确保文件开头没有空格。

如果您还有其他脚本,也可以在header('location: index.php');添加之后exit();

还要将您的重定向标头移到last之后if

如果有内容,那么您还可以通过注入javascript进行重定向:

<?php
    echo "<script>window.location.href='target.php';</script>";
    exit;
?>
