PHP中分页列和行的问题

我想在5列4行中显示20条记录，并在底部显示“下一条”/“上一条”按钮

由于某些原因，

$rowsperpage=5

会在1行5列中结束。如果我增加这个数字，它只会增加另一列

实际分页工作正常，但列和行不配合

你知道我怎样才能达到预期的效果吗

以下是我使用的代码：

<?php
// find out how many rows are in the table 
$sql = "SELECT COUNT(*) FROM users";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);
$r = mysql_fetch_row($result);
$numrows = $r[0];

// number of rows to show per page

$rowsperpage = 5;
// find out total pages
$totalpages = ceil($numrows / $rowsperpage);

// get the current page or set a default
if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) {
    // cast var as int
    $currentpage = (int) $_GET['currentpage'];
} else {
    // default page num
    $currentpage = 1;
} // end if

// if current page is greater than total pages...
if ($currentpage > $totalpages) {
    // set current page to last page
    $currentpage = $totalpages;
} // end if
// if current page is less than first page...
if ($currentpage < 1) {
    // set current page to first page
    $currentpage = 1;
} // end if

// the offset of the list, based on current page 
$offset = ($currentpage - 1) * $rowsperpage;

// get the info from the db 
$sql = "SELECT id, name, picture, phone, address1 FROM users LIMIT $offset,             $rowsperpage";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);

// while there are rows to be fetched...
echo "<table  style='width: 800px; height: 250px'>";

echo "<tr style='width: 800px;'>";

while ($list = mysql_fetch_assoc($result)) {
    // echo data
    echo "<td align='center' style='width: 800px; height: 250px'>" . $list        ['name'] . "<br /><a href='http://www.snarrf.com/onsale/detail.php?id=" . $list    ['id'] .

} // end while

    $prevpage = $currentpage - 1;
    // show < link to go back to 1 page
    //echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$prevpage'><</a> ";
} // end if 

// loop to show links to range of pages around current page
for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
    // if it's a valid page number...
    if (($x > 0) && ($x <= $totalpages)) {
        // if we're on current page...
        if ($x == $currentpage) {
            // 'highlight' it but don't make a link

        } // end else

我相信

while ($list = mysql_fetch_assoc($result)) {
    echo "<td align='center' style='width: 800px; height: 250px'>" . $list          ['name'] . "<br /><a href='http://www.snarrf.com/onsale/detail.php?id=" . $list    ['id'] . "'><img src='http://www.snarrf.com/onsale/nooks/" . $list['picture'] . "'     height='100' width='100'  border='0' /></a><br />" . $list['address1'] ."</td>" ;
}

while（$list=mysql\u fetch\u assoc（$result））{
回显“$list['name']”。

“$list['address1']”；
}

与

$rows\u计数器=0；
而（$list=mysql\u fetch\u assoc（$result））{
回显“$list['name']”。

“$list['address1']”；
如果（！（++$rows\u计数器%5）和$rowsperpage！=$rows\u计数器）
回声“；
}

应该做你想做的事。

太棒了，谢谢-我不得不稍微修改一下号码，但我得到的只是供参考的$行\计数器=20；结束时必须与$rowsperpage=20的值相同；在我的例子中，20（表示我想要的总记录数）和if（！（++$rows\u计数器%5）应反映所需的行数，因此5行20条记录，产生4列=成功！感谢帮助！！！Ranty-我如何直接与您联系？-如果可能，我想发言。您可能对我正在进行的项目感兴趣。请随时发送邮件给我：skylight@list.ru
