Question

我在完成任务后尝试将config.php文件包含在数据库中，重定向到其他页面但显示此错误消息。

“警告：无法修改标头信息 - 已发送的标头（输出始于 /home/prasan/public_html/theyplay.in/texttospeech/config.php:16）in /home/prasan/public_html/theyplay.in/texttospeech/input.php上线 14"

<?php
include("config.php");  
try {

$mi = $_POST['main'];
$i = $_POST['item'];

$dbo->query("INSERT INTO LD (mainitem, subitem, item,fav)VALUES ('$mi','$i',0)") ;

} catch (Exception $e) {
echo 'Caught exception: ',  $e->getMessage(), "\n";
}
header("Location: index.php");
?>

修改：config.php

<?php
$dbhost_name = "localhost";
$database    = "rrr";
$username    = "rrr";
$password    = "rrr";
try {
    $dbo = new PDO('mysql:host=' . $dbhost_name . ';dbname=' . $database, $username, $password);
}
catch (PDOException $e) {
    print "Error!: " . $e->getMessage() . "<br/>";
    die();
}
?>

Answer 1

标题重定向位置在try里面。因为你在header函数之前有一个回声

<?php
include("config.php");  
try {

    $mi = $_POST['main'];
    $i = $_POST['item'];

    $dbo->query("INSERT INTO LD (mainitem, subitem, item,fav)VALUES ('$mi','$i',0)") ;

    header("Location: index.php");

} catch (Exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "\n";
}

?>

Answer 2

这里，php已经在第16行

config.php 中向网络服务器发送了标头和输出缓冲区
你应该在任何回音或打印之前设置所有标题，

尝试从配置文件中删除任何/所有echo语句，否则从input.php中删除header("Location: index.php");

编辑：有一个选项供您使用，请替换为此代码

<?php include("config.php"); try { $mi = $_POST['main']; $i = $_POST['item']; $dbo->query("INSERT INTO LD (mainitem, subitem, item,fav)VALUES ('$mi','$i',0)") ; } catch (Exception $e) { echo 'Caught exception: ', $e->getMessage(), "\n"; } echo '<script>document.location = "index.php";</script>'; ?>

include和header函数不能在单个php文件中一起工作
