我有一些問題，每次刷新頁(yè)面時(shí)它都會(huì)復(fù)制最后一條評(píng)論。我嘗試使用重定向命令：header("location:../../index.php");但它給了我這個(gè)錯(cuò)誤：警告：無法修改標(biāo)頭信息 - 標(biāo)頭已發(fā)送（輸出開始于 /home/timpovodnik/gymshark.timpovodnik.xyz/header.php:87）在 /home/timpovodnik/gymshark.timpovodnik.xyz/PHP/comments.php 上第 9 行。這是我的代碼：<?php function setComments($conn) { // Funkcija, ki jo kasneje kli?em v LoseFat in GainMuscles datoteki //zraven dodamo se spremenljivko $conn, ki je iz datoteke baza.php if(isset($_POST['commentSubmit'])) { // ?e kliknemo na gumb za?ene kodo $uid = $_POST['uid']; $date = $_POST['date']; $message = $_POST['message']; $sql = "INSERT INTO komentarji (uime, sporocilo, datum, uporabnik_id, program_id, objava_id) VALUES ('$uid', '$message', '$date', '1', '1', '1')"; $result = mysqli_query($conn, $sql); // IZVEDE v BAZI header("location:../index.php"); exit(); } } function getComments($conn) { $sql = "SELECT * FROM komentarji"; $result = mysqli_query($conn, $sql); // IZVEDE v BAZI while ($row = mysqli_fetch_assoc($result)) { // da v tabelo in jo shrani v $row echo "<div class='row'>"; echo "<div class='comment-box'>"; echo $row['uime']."<br>"; echo $row['datum']."<br>"; echo nl2br($row['sporocilo']); echo "</div>"; echo "</div>"; } }?>

我修復(fù)了它并向其添加了 Mysqli 函數(shù)。
謝謝你的所有建議。
<?php
include 'baza.php';
if(isset($_POST['commentSubmit'])) { // ?e kliknemo na gumb za?ene kodo
$uid = $_POST['uid'];
$date = $_POST['date'];
$message = $_POST['message'];
$sql = "INSERT INTO komentarji (uime, sporocilo, datum) VALUES (?, ?, ?);";
$stmt = mysqli_stmt_init($conn);
if (!mysqli_stmt_prepare($stmt, $sql)) {
header("Location: ../loseFat.php?error=sqlerror"); // ?e stavek ne dela
exit();
}
else {
mysqli_stmt_bind_param($stmt, "sss", $uid, $message, $date);
mysqli_stmt_execute($stmt); // Executa stavek v DB
header("Location: ../loseFat.php?comment=success");
exit();
}
}
function getComments($conn) {
$sql = "SELECT * FROM komentarji";
$result = mysqli_query($conn, $sql); // IZVEDE v BAZI
while ($row = mysqli_fetch_assoc($result)) { // da v tabelo in jo shrani v $row
echo "<div class='row'>";
echo "<div class='comment-box'>";
echo $row['uime']."<br>";
echo $row['datum']."<br>";
echo nl2br($row['sporocilo']);
echo "</div>";
echo "</div>";
}
}
