您好,我在 1 页上编写了从数据库加载 5 个元素的代码,但它向我显示了一条通知: undefined index :recordstart

这是我的代码

   <?php
include 'php_script/init.php';
$pagesize = 5;

$recordstart = (int) $_GET['recordstart'];
$recordstart = (isset($_GET['recordstart'])) ? $recordstart : 0;


$sql01 = "SELECT * FROM movies ORDER BY year DESC LIMIT $recordstart, $pagesize";
$records=mysql_query($sql01);

$result = mysql_query("SELECT count(id) FROM movies");
$totalrows = mysql_fetch_row($result);

while ($movies=mysql_fetch_assoc($records)){
echo '<div class="movie_box"><p><div class="news_img"><div class="cover"><img src="'.$movies['cover'].'" width = "183px" height = "271px"/></div><br><button class="trailer_button" type="button">Trailer</button></div><strong><p class="h3"><div class="content">'.$movies['name'].'</p></strong>'.$movies['plot'].'<br><br><strong>Žanr</strong>:'.$movies['genre'].'<br><strong>IMDB ocjena</strong>:'.$movies['IMDBrating'].'<br><strong>Director</strong>:'.$movies['director'].'<br><strong>Glumci</strong>:'.$movies['Starring'].'<br><strong>Ocjena korisnika</strong>:</div><br><div class="trailer">'.$movies['trailer'].'</div><div class="dark"></div></p></div>';
}

if ($recordstart > 0){
$prev = $recordstart - $pagesize;
$url = $_SERVER['PHP_SELF'].'?recordstart=$prev';
printf('<a id="prev" href="%s"><<</a>',$url);
}

if ($totalrows > ($recordstart + $pagesize)){
$next = $recordstart + $pagesize;
$url = $_SERVER['PHP_SELF'].'?recordstart=$next';
printf('<a id="next" href="%s">>></a>',$url);
}
?>

我无法用其他答案解决我的问题!!!
