我覺得我問了很多問題。PHP分頁不工作,我不知道爲什麼
不管怎樣,我正在寫一些數據庫條目分頁,它看起來聲音給我,但是當我點擊鏈接它只是顯示前10個職位,並沒有別的。
整個事情就在這裏:
<?php
$post_limit = 10;
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("failed to connect: " . $conn->connect_error);
}
$sql = "SELECT count(id) FROM $tablename";
$result = mysqli_query($conn, $sql);
if (!$result) {
echo "you fucked up";
} else {
echo $row["id"];
}
$row = mysqli_fetch_array($result, MYSQL_NUM);
$post_count = $row[0];
if(isset($_GET['page'])) {
$page = $_GET['page'] + 1;
$offset = $post_limit * $page;
} else {
$page = 0;
$offset = 0;
}
$post_left = $post_count - ($page * $post_limit);
$sql = "SELECT id, upvotes, downvotes, name, title, message, date, time FROM posts ORDER BY date DESC, time DESC LIMIT $offset, $post_limit";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
while($row = $result->fetch_assoc()) {
echo "<br><div id='messageBar'>";
echo " ❖ </b>";
echo "Posted by <b>";
echo htmlspecialchars($row["name"]);
echo "</b> on ";
echo $row["date"];
echo " at ";
echo $row["time"];
if (!empty($row['title'])) {
echo " - <b>";
echo htmlspecialchars($row["title"]);
echo "</b>";
}
echo "<span style='float: right'>#";
echo $row["id"];
echo "</span>";
echo "</div><div id='messageContent'>";
echo htmlspecialchars($row["message"]);
echo "<br><br><span id='commentLink'><a class='commentLink' href='thread.php?id=$row[id]'>view thread </a></span>";
echo "<br></div><br><hr>";
}
} else {
echo "<br>";
echo "<center><i>it's dusty in here</i></center>";
echo "<br>";
}
if ($page > 0) {
$last = $page - 2;
echo "<a href='$_PHP_SELF?page = $last'>previous page</a> | ";
echo "<a href='$_PHP_SELF?page = $page'>next page</a>";
} else if ($page == 0) {
echo "<a href='$_PHP_SELF?page = $page'>next page</a>";
} else if ($post_left < $post_limit) {
$last = $page - 2;
echo "<a href='$_PHP_SELF?page = $last'>previous page</a>";
}
$conn->close();
?>
的鏈接,下一個頁面出現在底部,但點擊它把你帶到你已經在用相同的最近10個帖子的頁面。
我想學習PHP的,因爲我去,所以我感謝所有幫助。謝謝!
正確的語法是'$ _GET [ '頁']','不是$ _GET { '頁面'}'。 – aynber
謝謝,修正了這種語法,但問題仍然存在。 – Treedot
這是我經常提醒我編程時很糟糕 – Treedot
