// Adam's Custom PHP MySQL Pagination Tutorial and Script

// http://www.youtube.com/watch?v=K8xYGnEOXYc
include 'core/init.php';
//////////////  QUERY THE MEMBER DATA INITIALLY LIKE YOU NORMALLY WOULD
$sql = mysql_query("SELECT userid, first_name, last_name FROM users ORDER BY userid ASC");
//////////////////////////////////// Adam's Pagination Logic    //
$nr = mysql_num_rows($sql); // Get total of Num rows from the database query
if (isset($_GET['pn'])) { // Get pn from URL vars if it is present
$pn = preg_replace('#[^0-9]#i', '', $_GET['pn']); // filter everything but numbers for security(new)
//$pn = ereg_replace("[^0-9]", "", $_GET['pn']); // filter everything but numbers for security(deprecated)
} else { // If the pn URL variable is not present force it to be value of page number 1
$pn = 1;
}
//This is where we set how many database items to show on each page
$itemsPerPage = 10;
// Get the value of the last page in the pagination result set
$lastPage = ceil($nr / $itemsPerPage);
// Be sure URL variable $pn(page number) is no lower than page 1 and no higher than $lastpage
if ($pn < 1) { // If it is less than 1
$pn = 1; // force if to be 1
} else if ($pn > $lastPage) { // if it is greater than $lastpage
$pn = $lastPage; // force it to be $lastpage's value
}
// This creates the numbers to click in between the next and back buttons
// This section is explained well in the video that accompanies this script
$centerPages = "";

// This line sets the "LIMIT" range... the 2 values we place to choose a range of rows from database in our query
$limit = 'LIMIT ' .($pn - 1) * $itemsPerPage .',' .$itemsPerPage;

// $sql2 is what we will use to fuel our while loop statement below

这个问题是它显示的信息非常粗糙和可怕。我还没有将它插入我的网站设计中。我希望能够在我网站上使用的整洁表格中呈现信息,这里是该空表的标准代码:

<table class="table table-striped">
                                <thead>
                                    <tr>
                                        <th>
                                            #
                                        </th>

                                    </tr>
                                </thead>

                                    </tr>
                                    <tr>
                                        <td>
                                            3
                                        </td>
                                        <td>
                                            Larry
                                        </td>
                                        <td>
                                            the Bird
                                        </td>
                                        <td>
                                            @twitter
                                        </td>
                                    </tr>
                                </tbody>
                            </table>

如何从顶级代码中获取信息以显示在整洁的表格中?显然,一旦新用户注册,代码就必须自动添加新行和列,或者不确定如何做到这一点?我是PHP和MYSQL的新手,所以如果你能提供令人惊叹的细节!

谢谢!

您可以用以下内容替换while:

$outputList = '<table class="table table-striped">
                                <thead>
                                    <tr>
                                        <th>
                                            #
                                        </th>
                                        <th>
                                            First Name

}

$outputList .= '</tbody>
