Question

我有一个数据库，我试图通过PHP显示进行编辑。在主页面上，我只想显示表格的前15行，然后让用户点击以生成更多的表格行。

<?php 
include('../config.php'); 
$result = $mysqli->query("SELECT uid, title, description, tblFacilityHrsDateTimes.* FROM tblFacilityHrs LEFT JOIN tblFacilityHrsDateTimes ON tblFacilityHrs.uid = tblFacilityHrsDateTimes.owner_uid ORDER BY tblFacilityHrs.title") or die($mysqli->error);
    while($row =$result->fetch_assoc()){ 
        extract ($row);
        echo "<tr>";  
            echo "<td> {$id} </td>";  //hide when finished
            echo "<td> {$title} </td>"; 
            echo "<td> {$description} </td>";
            echo "<td> {$startEventDate} </td>";
            echo "<td> {$endEventDate} </td>";
            echo "<td> {$startTime} </td>";
            echo "<td> {$endTime} </td>";
            echo "<td> {$days} </td>";
            echo "<td> {$recurrence} </td>";
            echo "<td> {$finalDate} </td>";
            echo "<td>";
            echo "<a class=\"buttons\" href=edit.php?id={$id}&uid={$uid}>Edit</a><span class='icon'></span></a>
";
            echo " / ";
            echo "<a class=\"buttons\" href='javascript: Confirm()'>Delete</a>";
            echo "</td>";
        echo "</tr>";
        echo "</div>"; 
    } 

echo "</table>";

$result->free();
$mysqli->close();

?>

Answer 1

使用LIMIT：

"SELECT uid, title, description, tblFacilityHrsDateTimes.* FROM tblFacilityHrs LEFT JOIN tblFacilityHrsDateTimes ON tblFacilityHrs.uid = tblFacilityHrsDateTimes.owner_uid ORDER BY tblFacilityHrs.title LIMIT 15"

Answer 2

查看limit语法in this manual page。 select * from table limit 0,15将返回以offset 0（第一行）开头的15行。对于第二页，您使用limit 15, 15获取第16-30行，然后使用limit 30,15，依此类推。

你需要看看Paging。本教程可能有所帮助：http://www.php-mysql-tutorial.com/wikis/php-tutorial/paging-using-php.aspx

Answer 4

可能你正在寻找分页，这可以通过mysql LIMIT

来完成

像这样的东西

$result = $mysqli->query("SELECT uid, title, description, tblFacilityHrsDateTimes.* FROM tblFacilityHrs LEFT JOIN tblFacilityHrsDateTimes ON tblFacilityHrs.uid = tblFacilityHrsDateTimes.owner_uid ORDER BY tblFacilityHrs.title LIMIT 15, $page ")

$ page用于抵消
