搜索特定类(class)后，结果会正确显示，但一旦我更改页面，它就会恢复显示所有可用结果。如何保留搜索词结果？
这是代码
<?php
$con = mysqli_connect("localhost", "root", "root", "courses");
// $total = mysqli_query($con, "SELECT count(title) as total")->fetch()['total']);
if(isset($_GET['searchword'])){
$searchword = $_GET['searchword'];
}
else {
$searchword = "";
}
$result = mysqli_query($con, "SELECT count(title) FROM course WHERE title LIKE '$searchword%'");
$row = mysqli_fetch_row($result);
// Total rows.
$rowstotal = $row[0];
//pages
$page = isset($_GET['page']) ? (int)$_GET['page'] : 1;
$perPage = isset($_GET['per-page']) && $_GET['per-page'] <= 100 ? (int)$_GET['per-page'] : 10;
$start = ($page > 1) ? ($page * $perPage) - $perPage : 0;
$pages = $rowstotal / $perPage;
$sql = "SELECT * FROM course WHERE title LIKE '%$searchword%' ORDER BY title ASC LIMIT {$start},{$perPage}";
$query = mysqli_query($con, $sql);
$resultsText = "$rowstotal results";
$resultsList = '';
while($row = mysqli_fetch_array($query, MYSQLI_ASSOC)){
$courseId = $row["id"];
$courseAward = $row["award"];
$courseName = $row["title"];
$courseDetails = $row["summary"];
$resultsList .= '<a href="course-page.php?id='.$courseId.'">'.$courseAward.' '.$courseName.'</a> <br>'.$courseDetails.'<br/>';
}
mysqli_close($con);
?>

最佳答案
您的页面链接不保留 searchword 参数。改变这个:
<a href="?page=<?php echo $x; ?>&per-page=<?php echo $perPage; ?>"<?php if($page === $x) { echo ' class="selected"'; } ?>><?php echo $x; ?></a>
为此:
<a href="?page=<?php echo $x; ?>&per-page=<?php echo $perPage; ?>&searchword=<?php echo $searchword; ?>"<?php if($page === $x) { echo ' class="selected"'; } ?>><?php echo $x; ?></a>
