在我一直在努力的當前頁面上，我已經設置了代碼，它可以用作實時博客/更新類型的系統。問題是，我從我的數據庫中加載我的PHP中的東西，然後我有AJAX鏈接到另一個文件，它將獲取數據庫內容並刷新它包含在我的網站上的區域。AJAX刷新 - 重複已經加載的數據來自數據庫的數據
因此'這意味着它會自動更新每15000毫秒與來自數據庫的數據。問題是，它已經加載了現有的數據。所以無論如何。每15000毫秒將刷新該div，因此頁面上已有的數據將被複制。
更加清晰Bulletpoint形式
- PHP查詢數據庫，回聲的出來的數據。
- AJAX每15000毫秒檢查一個php頁面，並在第一頁上顯示回顯。
- 不只是發佈新內容，它只是複製原始內容。 （可以有雙帖或甚至tripple。它似乎有所不同）
我只是真的進入PHP，我沒有把很多時間放進去，我的AJAX知識是不存在的，所以它提出這樣的問題。我試着搜索如何僅在第一頁上回顯現有數據，即使第二頁正在處理更新。
但是，這是代碼，對不起，如果它是凌亂的，或正確地做的事情。我仍然在學習這種語言。
第一頁matchdayupdates.php？ID =（在這種情況下，id爲6）
$id = $_GET['id'];
if(isset($_GET['id'])) {
$requestMatchInformation = mysqli_query($connect, "SELECT * FROM matchinfo WHERE pageid='$id' LIMIT 500");
while ($row = mysqli_fetch_assoc($requestMatchInformation)) {
$pageid = $row['pageid'];
$type = $row['type'];
$postheader = $row['postheader'];
$postcontent = $row['postcontent'];
$posttime = $row['posttime'];

<br />
<p class='post-content'>$postcontent</p>
</div>
</div>
</div>
</div>";
}
$requestEventsInformation = mysqli_query($connect, "SELECT * FROM events WHERE id='$id'");
while($row = mysqli_fetch_assoc($requestEventsInformation)) {
$opponent = $row['opponent'];
$datetime = $row['datetime'];
$datetimedisplay = $row['datetimedisplay'];
$location = $row['location'];
$datepassed = $row['datepassed'];
$rowonescore = $row['rowonescore'];
$rowtwoscore = $row['rowtwoscore'];
$rowoneplayers = $row['rowoneplayers'];
$rowtwoplayers = $row['rowtwoplayers'];
}
}
else {
}
if(!$requestEventsInformation && !$requestMatchInformation) {
echo '<div class="match-notice"><h4>There are currently no updates, this page will auto-update when there are new updates.</h4></div>';
}
echo $id;
?>
<script>
var auto_refresh = setInterval(function() {
$('.center-match-container').fadeOut('slow', function() {
$(this).load('/esports/match/matchinforequest.php?id=<?php echo $id; ?>', function() {
$(this).fadeIn('slow');
});
});
$.ajaxSetup({ cache: true });
}, 15000);
</script>第二頁matchinforequest.php？ID =（再次此ID 6）
$id = $_GET['id'];
if(isset($_GET['id'])) {
$requestMatchInformation = mysqli_query($connect, "SELECT * FROM matchinfo WHERE pageid='$id' LIMIT 500");
while ($row = mysqli_fetch_assoc($requestMatchInformation)) {
$pageid = $row['pageid'];

<br />
<br />
<p class='post-content'>$postcontent</p>
</div>
</div>
</div>
</div>";
}
$requestEventsInformation = mysqli_query($connect, "SELECT * FROM events WHERE id='$id'");
while($row = mysqli_fetch_assoc($requestEventsInformation)) {
$opponent = $row['opponent'];
$datetime = $row['datetime'];
$datetimedisplay = $row['datetimedisplay'];

echo "Received Data";

else {
}
而不是追加數據，取而代之的是什麼問題... –
