php - 显示数据库中的条目，从最新到最旧列出它们并在一定数量后停止？

Question

我的数据库中有以下表格：

1. ID
2. 标题
3. 标题
4. 内容
5. 日期
6. 标签
7. 用户名
8. 像
9. 不喜欢
10. 评论

我已经连接了数据库，以便它显示行中的内容，但我不知道如何制作它，以便每次创建新条目时它都会生成并列出一个“发布块”。我还想将它们从最新帖子到最旧帖子列出，同时将帖子限制为每页 10-20 个。

<?php

$connect = mysql_connect('localhost','root','','andrewryan') or die('error connection');

mysql_select_db('andrewryan');

$query = "Select * FROM entry";
$result = mysql_query($query);
$row = mysql_fetch_array($result);

$username = $row['username'];
$title = $row['title'];
$heading = $row['heading'];
$content = $row['content'];
$tags = $row['tags'];
$like = $row['like'];
$dislike = $row['dislike'];
$comment = $row['comment'];
$date = $row['date'];
?>

我还有另一个页面，只有一个 html 块。这是 post 框架，所有变量都在需要的地方给出。如果有帮助，可以在此链接中找到有关我要做什么的任何参考：这里

Answer 1

1. 选择您有兴趣获取的所有字段。
2. 使用 DATE_FORMAT 函数格式化日期字段并分配给新别名。我将其命名为 ndate。
   1. 然后按日期订购

SELECT username,title,heading,content,tags,like,dislike,comment,DATE_FORMAT(date, '%d-%M-%Y') AS ndate FROM entry ORDER BY ndate

获取日期为 $row['ndate']

Answer 2

至于查询：

// Tildes on date since it is a keyword and some databases will error out without them
// Order by date is if you are using a compatible storing: unix timestamp or DateTime field
$query = "Select * FROM entry ORDER BY `date` DESC";
$result = mysql_query($query);
$rowCount = 0;
while($row = mysql_fetch_array($result)) {
    $username[$rowCount] = $row['username'];
    $title[$rowCount] = $row['title'];
    $heading[$rowCount] = $row['heading'];
    $content[$rowCount] = $row['content'];
    $tags[$rowCount] = $row['tags'];
    $like[$rowCount] = $row['like'];
    $dislike[$rowCount] = $row['dislike'];
    $comment[$rowCount] = $row['comment'];
    $date[$rowCount] = $row['date'];
    $rowCount++;
}

这是就显示帖子而言：

// limit is used to show the max posts per page.
$limit = 20;

//The following for is for paging
for($i = 1; $i <= $numofpages; $i++){
    if($i == $page){
        echo $i . " ";
    }else{
        echo "<a href='page.php?page=" . $i . "'>" . $i . "</a> ";
    }
}

// The following is to show your post blocks
for($j = 0; $j < $limit; $j++){
    //This will give you the appropriate post for the page
    $temp = $j + (($page * $limit) - $limit);
    // Your code to show your post blocks
    echo $username[$temp]; //For example, just format for your site layout.
}
